KENNEDY SPACE CENTER, FL – OSIRIS-Rex, the first American sponsored probe aimed at retrieving “pristine materials” from the surface of an asteroid and returning them to Earth has been fully assembled at its Florida launch base and is ready to blastoff ten days from today on Sep. 8. It’s a groundbreaking mission that could inform us about astrobiology and the ‘Origin of Life.’

“We are interested in that material because it is a time capsule from the earliest stages of solar system formation,” said Dante Lauretta, principal investigator for OSIRIS-REx at the University of Arizona, Tucson, in an interview with Universe Today beside the completed spacecraft inside the Payloads Hazardous Servicing Facility, or PHSF, clean room processing facility at NASA’s Kennedy Space Center in Florida.

With virtually all prelaunch processing complete, leading members of the science, engineering and launch team including Lauretta met with several members of the media, including Universe Today, inside the clean room for a last and exclusive up-close look and briefing with the one-of-its-kind $800 million Asteroid sampling probe last week.

NASA’s Origins, Spectral Interpretation, Resource Identification, Security – Regolith Explorer (OSIRIS-REx) spacecraft will launch from Space Launch Complex 41 at Cape Canaveral Air Force Station on a United Launch Alliance Atlas V rocket on September 8 at 7:05 p.m. EDT.

OSIRIS-REx goal is to fly on a roundtrip seven-year journey to the near-Earth asteroid target named Bennu and back. 101955 Bennu is a near Earth asteroid and was selected specifically because it is a carbon-rich asteroid.

While orbiting Bennu it will move in close and snatch pristine soil samples containing organic materials from the surface using the TAGSAM collection dish, and bring them back to Earth for study by researchers using all of the most sophisticated science instruments available to humankind.

“The primary objective of the OSIRIS-Rex mission is to bring back pristine material from the surface of the carbonaceous asteroid Bennu, OSIRIS-Rex Principal Investigator Dante Lauretta told Universe Today in the PHSF, as the probe was undergoing final preparation for shipment to the launch pad.

“It records the very first material that formed from the earliest stages of solar system formation. And we are really interested in the evolution of carbon during that phase. Particularly the key prebiotic molecules like amino acids, nucleic acids, phosphates and sugars that build up. These are basically the biomolecules for all of life.”

OSIRIS-REx will gather rocks and soil and bring at least a 60-gram (2.1-ounce) sample back to Earth in 2023. It has the capacity to scoop up to about 1 kg or more.

The mission will help scientists investigate how planets formed and how life began. It will also improve our understanding of asteroids that could impact Earth by measuring the Yarkovsky effect.

I asked Lauretta to explain in more detail why was Bennu selected as the target to answer fundamental questions related to the origin of life?

“We selected asteroid Bennu as the target for this mission because we feel it has the best chance of containing those pristine organic compounds from the early stage of solar system formation,” Lauretta told me.

“And that information is based on our ground based spectral characterization using telescopes here on Earth. Also, space based assets like the Hubble Space Telescope and the Spitzer Space Telescope.”

What is known about the presence of nitrogen containing compounds like amino acids and other elements on Bennu that are the building blocks of life?

“When we look at the compounds that make up these organic materials in these primitive asteroidal materials, we see a lot of carbon,” Lauretta explained.

“But we also see nitrogen, oxygen, hydrogen, sulfur and phosphorous. We call those the CHONPS. Those are the six elements we really focus on when we look at astrobiology and prebiotic chemistry and how those got into the origin of life.”

The OSIRIS-REx spacecraft was built for NASA by prime contractor Lockheed Martin at their facility near Denver, Colorado and flown to the Kennedy Space Center on May 20.

For the past three months it has undergone final integration, processing and testing inside the PHSF under extremely strict contamination control protocols to prevent contamination by particle, aerosols and most importantly organic residues like amino acids that could confuse researchers seeking to discover those very materials in the regolith samples gathered for return to Earth.

The PHFS clean room was most recently used to process the Orbital ATK Cygnus space station resupply vehicles. It has also processed NASA interplanetary probes such as the Curiosity Mars Science Laboratory and MAVEN Mars orbiter missions.

The spacecraft will reach Bennu in 2018. Once within three miles (5 km) of the asteroid, the spacecraft will begin at least six months of comprehensive surface mapping of the carbonaceous asteroid, according to Heather Enos, deputy principal investigator, in an interview with Universe Today.

“We will then move the spacecraft to within about a half kilometer or so to collect further data,” Enos elaborated.

It will map the chemistry and mineralogy of the primitive carbonaceous asteroid. The team will initially select about 10 target areas for further scrutiny as the sampling target. This will be whittled down to two, a primary and backup, Enos told me.

After analyzing the data returned, the science team then will select a site where the spacecraft’s robotic sampling arm will grab a sample of regolith and rocks. The regolith may record the earliest history of our solar system.

Engineers will command the spacecraft to gradually move on closer to the chosen sample site, and then extend the arm to snatch the pristine samples the TAGSAM sample return arm.

PI Lauretta will make the final decision on when and which site to grab the sample from.

“As the Principal Investigator for the mission I have responsibility for all of the key decisions during our operations,” Lauretta replied. “So we will be deciding on where we want to target our high resolution investigations for sample site evaluation. And ultimately what is the one location we want to send the spacecraft down to the surface of the asteroid to and collect that sample.”

“And then we have to decide like if we collected enough sample and are we ready to stow it in the sample return capsule. Or are we going to use one of our 2 contingency bottles of gas to go for a second attempt.”

“The primary objective is one successful sampling event. So when we collect 60 grams or 2 ounces of sample then we are done!”

“In the event that we decide to collect more, it will be intermixed with anything we collected on the first attempt.”

The priceless sample will then be stowed in the on board sample return capsule for the long journey back to Earth.

Bennu is an unchanged remnant from the collapse of the solar nebula and birth of our solar system some 4.5 billion years ago, little altered over time.

Bennu is a near-Earth asteroid and was selected for the sample return mission because it could hold clues to the origin of the solar system and host organic molecules that may have seeded life on Earth.

OSIRIS-REx is the third mission in NASA’s New Frontiers Program, following New Horizons to Pluto and Juno to Jupiter, which also launched on Atlas V rockets.

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is responsible for overall mission management.

OSIRIS-REx complements NASA’s Asteroid Initiative – including the Asteroid Redirect Mission (ARM) which is a robotic spacecraft mission aimed at capturing a surface boulder from a different near-Earth asteroid and moving it into a stable lunar orbit for eventual up close sample collection by astronauts launched in NASA’s new Orion spacecraft. Orion will launch atop NASA’s new SLS heavy lift booster concurrently under development.

NASA’s JUNO spacecraft successfully swooped over the Jovian cloud tops today, Saturday, Aug. 27, gathering its first up close images and science observations of the ‘King of the Planets’ since braking into orbit on America’s Independence Day.

Saturdays’ close encounter with Jupiter soaring over its north pole was the first of 36 planned orbital flyby’s by Juno during the scheduled 20 month long prime mission.

“Soarin’ over #Jupiter. My 1st up-close look of the gas-giant world was a success!” the probe tweeted today post-flyby.

NASA released Juno’s first up-close image taken by the JunoCam visible light camera just hours later – as seen above.

Juno was speeding at some 130,000 mph (208,000 kilometers per hour) during the time of Saturday’s closest approach at 9:44 a.m. EDT (6:44 a.m. PDT 13:44 UTC) over the north polar region.

It passed merely 2,600 miles (4,200 kilometers) above the turbulent clouds of the biggest planet in our solar system during its initial 53.5 day polar elliptical capture orbit.

And apparently everything proceeded as the science and engineering team leading the mission to the gas giant had planned.

“Early post-flyby telemetry indicates that everything worked as planned and Juno is firing on all cylinders,” said Rick Nybakken, Juno project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California, in a statement.

Indeed Saturday’s encounter will count as the closest of the entire prime mission. It also marks the first time that the entire suite of nine state-of-the-art science instruments had been turned on to gather the totally unique observations of Jupiter’s interior and exterior environment.

“We are getting some intriguing early data returns as we speak,” said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio, in a statement.

“This is our first opportunity to really take a close-up look at the king of our solar system and begin to figure out how he works.”

Additional up-close high resolution imagery of the Jovian atmosphere, swirling cloud tops and north and south poles snapped by JunoCam will be released in the coming weeks, perhaps as soon as next week.

“We are in an orbit nobody has ever been in before, and these images give us a whole new perspective on this gas-giant world,” said Bolton.

“It will take days for all the science data collected during the flyby to be downlinked and even more to begin to comprehend what Juno and Jupiter are trying to tell us.”

The prime mission is scheduled to end in February of 2018 with a suicide plunge into the Jovian atmosphere to prevent any possible contamination with Jupiter’s potentially habitable moons such as Europa and Ganymede.

“No other spacecraft has ever orbited Jupiter this closely, or over the poles in this fashion,” said Steve Levin, Juno project scientist from NASA’s Jet Propulsion Laboratory in Pasadena, California. “This is our first opportunity and there are bound to be surprises. We need to take our time to make sure our conclusions are correct.”

The team did release an approach image taken by JunoCam on Aug. 23 when the spacecraft was 2.8 million miles (4.4 million kilometers) from the gas giant planet on the inbound leg of its initial 53.5-day capture orbit.

One additional long period orbit is planned. The main engine will fire again in October to reduce the orbit to the 14 day science orbit.

The solar powered probe will collect unparalleled new data that will unveil the hidden inner secrets of Jupiter’s origin and evolution as it peers “beneath the obscuring cloud cover of Jupiter and study its auroras to learn more about the planet’s origins, structure, atmosphere and magnetosphere.”

The $1.1 Billion Juno was launched on Aug. 5, 2011 from Cape Canaveral Air Force Station, Florida atop the most powerful version of the Atlas V rocket augmented by 5 solid rocket boosters and built by United Launch Alliance (ULA). That same Atlas V 551 version recently launched MUOS-5 for the US Navy on June 24.

The Juno spacecraft was built by prime contractor Lockheed Martin in Denver.

The last NASA spacecraft to orbit Jupiter was Galileo in 1995. It explored the Jovian system until 2003.

In the final weeks of the approach before Jupiter Orbit Insertion (JOI), JunoCam captured dramatic views of Jupiter and all four of the Galilean Moons moons — Io, Europa, Ganymede and Callisto.

At the post JOI briefing at JPL on July 5, these were combined into a spectacular JunoCam time-lapse movie released by Bolton and NASA.

Watch and be mesmerized -“for humanity, our first real glimpse of celestial harmonic motion” says Bolton.

Video caption: NASA’s Juno spacecraft captured a unique time-lapse movie of the Galilean satellites in motion about Jupiter. The movie begins on June 12th with Juno 10 million miles from Jupiter, and ends on June 29th, 3 million miles distant. The innermost moon is volcanic Io; next in line is the ice-crusted ocean world Europa, followed by massive Ganymede, and finally, heavily cratered Callisto. Galileo observed these moons to change position with respect to Jupiter over the course of a few nights. From this observation he realized that the moons were orbiting mighty Jupiter, a truth that forever changed humanity’s understanding of our place in the cosmos. Earth was not the center of the Universe. For the first time in history, we look upon these moons as they orbit Jupiter and share in Galileo’s revelation. This is the motion of nature’s harmony.

KENNEDY SPACE CENTER, FL – Scarcely three weeks after the mesmerizing midnight launch and landing of a SpaceX Falcon 9 rocket that delivered over two tons of science and critical hardware to the space station for NASA, the innovative firm is set to repeat the back to back space feats – with a few big twists – during a post midnight launch this Sunday, Aug.14 of a Japanese telecom satellite.

In less than 24 hours, a freshly built SpaceX Falcon 9 is set to transform night into day and launch the JCSAT-16 communications satellite from Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida.

And some nine minutes later, the 15 story Falcon 9 first stage is scheduled to make a pinpoint soft landing on a tiny, prepositioned drone ship at sea in the vast Atlantic Ocean.

To date SpaceX has successfully soft landed 5 first stage boosters over the past eight months – two by land and three by sea.

Nighttime liftoffs are always a viewing favorite among the general public – whether visiting from near or far. And this one is virtually certain to offer some spectacular summer fireworks since the weather looks rather promising – if all goes well.

Sunday’s launch window opens at 1:26 a.m. EDT and extends two hours long for the 229 foot tall Falcon 9 rocket. The window closes at 3:26 a.m. EDT.

The commercial mission involves lofting the JCSAT-16 Japanese communications satellite to a Geostationary Transfer Orbit (GTO) for SKY Perfect JSAT – a leading satellite operator in the Asia – Pacific region. JCSAT-16 will be positioned 22,300 miles (35,800 kilometers) above the equator.

Sunday’s launch is the second this year for SKY Perfect JSAT. The JCSAT-14 satellite was already launched earlier this year on May 6.

You can watch the launch live via a special live webcast from SpaceX.

The SpaceX webcast will be available starting at about 20 minutes before liftoff, at approximately 1:06 a.m. EDT at SpaceX.com/webcast

The weather currently looks very good. Air Force meteorologists are predicting an 80 percent chance of favorable weather conditions at launch time in the wee hours early Sunday morning.

The primate concerns are for violations of the Cumulus Cloud and Think Cloud rules.

The U.S. Air Force’s 45th Space Wing will support SpaceX’s Falcon 9 launch of JCSAT-16.

In cases of any delays for technical or weather issues, a backup launch opportunity exists 24 hours later on Monday morning with a 70 percent chance of favorable weather.

The rocket has already been rolled out to the launch pad on the transporter and raised to its vertical position.

The path to launch was cleared following the successful Aug. 10 hold down static fire test of the Falcon 9 first stage Merlin 1-D engines. SpaceX routinely performs the hot fire test to ensure the rocket is ready.

Watch this crystal clear video of the Static Fire Test from USLaunchReport:

Via a fleet of 15 satellites, Tokyo, Japan based SKY Perfect JSAT provides high quality satellite communications to its customers.
The JCSAT-16 communications satellite was designed and manufactured by Space Systems/Loral for SKY Perfect JSAT Corporation.

JCSAT-16 satellite will separate from the second stage and will be deployed about 32 minutes after liftoff from Cape Canaveral. The staging events are usually broadcast live by SpaceX via stunning imagery from onboard video cameras.

A secondary objective is to try and recover the first stage booster via a propulsive landing on an ocean-going platform.

This booster is again equipped with 4 landing legs and 4 grid fins.

Following stage separation, SpaceX will try to soft land the first stage on the “Of Course I Still Love You” drone ship positioned about 400 miles (650 km) off shore of Florida’s east coast in the Atlantic Ocean.

But SpaceX officials say landings from GTO mission destinations are extremely challenging because the first stage will be subject to extreme velocities and re-entry heating.

If all goes well with the supersonic retropropulsion landing on the barge, the booster will arrive back into Port Canaveral a few days later.

The ‘Return to Flight’ launch of Orbital ATK’s re-engined Antares rocket on a cargo resupply launch for NASA bound for the space station has been postponed for at least another month into September due to the need for further analysis of the revamped booster and other factors.

Today’s announcement by Orbital ATK of a launch delay to mid-September comes barely two weeks before the long hoped for liftoff – which had been scheduled for late afternoon on August 22 from Orbital ATK’s launch base on Virginia’s picturesque eastern shore.

The Antares 230 medium-class commercial launch vehicle rocket has been upgraded with new first stage Russian-built RD-181 engines that must be fully validated before launching NASA’s precious cargo to the International Space Station (ISS).

Almost simultaneously, the Japan Aerospace Exploration Agency (JAXA) decided to postpone the upcoming launch of their next HTV H-11 Transfer Vehicle “KOUNOTORI6” (HTV6) which had been slated for October 1 from the Tanegashima Space Center.

JAXA said a leak was detected during pressure testing which must be fixed before any launch attempt.

Antares could potentially take the launch slot vacated by JAXA.

Orbital ATK cited multiple factors for the launch postponement from NASA’s Wallops Flight Facility in a short statement released today, August 10.

“Due to a variety of interrelated factors, including the company’s continuing processing, inspection and testing of the flight vehicle at Wallops Island, and NASA’s scheduling of crew activities on the International Space Station in preparation for upcoming cargo and crew launches, Orbital ATK is currently working with NASA to target a window in the second half of September for the launch of the OA-5 mission,” Orbital ATK announced.

Also there are reports that the re-engined Antares experience some form of unexpected ‘vibrations’ during the recent static fire test conducted in May.

This is the latest in a string of Antares launch delays, running back to the start of 2016.

Furthermore, a new launch date won’t be announced for at least several more weeks.

“A more specific launch date will be identified in the coming weeks,” said Orbital ATK.

Orbital ATK’s Antares commercial rocket had to be overhauled with completely new first stage engines following the catastrophic launch failure nearly two years ago on October 28, 2014 just seconds after blastoff that doomed the Orb-3 resupply mission to the space station.

The goal of the Antares ‘Return to Flight’ mission is to launch Orbital ATK’s Cygnus cargo freighter on the OA-5 resupply mission for NASA to the International Space Station (ISS).

To that end the aerospace firm recently completed a successful 30 second long test firing of the re-engined first stage on May 31 at Virginia Space’s Mid-Atlantic Regional Spaceport (MARS) Launch Pad 0A – as I reported here earlier.

Teams from Orbital ATK and NASA have been scrutinizing the data in great detail ever since then to ensure the rocket is really ready before committing to the high stakes launch.

“Orbital ATK completed a stage test at the end of May and final data review has confirmed the test was successful, clearing the way for the Antares return to flight,” said the company.

“Simultaneously, the company has been conducting final integration and check out of the flight vehicle that will launch the OA-5 mission to ensure that all technical, quality and safety standards are met or exceeded.”

Antares launches had immediately ground to a halt following the devastating launch failure 22 months ago which destroyed the rocket and its critical payload of space station science and supplies for NASA in a huge fireball just seconds after blastoff – as witnessed by this author.

As a direct consequence of the catastrophic launch disaster, Orbital ATK managers decided to outfit the Antares medium-class rocket with new first stage RD-181 engines built in Russia.

The RD-181 replaces the previously used AJ26 engines which failed moments after liftoff during the last launch on Oct. 28, 2014 resulting in a catastrophic loss of the rocket and Cygnus cargo freighter.

The RD-181 flight engines are built by Energomash in Russia and had to be successfully tested via the static hot fire test to ensure their readiness.

Whenever it does fly on the OA-5 mission, Orbital ATK’s Cygnus cargo craft will be loaded with approximately 2,400 kg (5,290 lbs.) of supplies and science experiments for space station and its six person crews.

Under the Commercial Resupply Services (CRS) contract with NASA, Orbital ATK will deliver approximately 28,700 kilograms of cargo to the space station. OA-5 is the sixth of these missions.

How Long Does it Take to get to the Asteroid Belt?

It's long been thought that a giant asteroid, which broke up long ago in the main asteroid belt between Mars and Jupiter, eventually made its way to Earth and led to the extinction of the dinosaurs. New studies say that the dinosaurs may have been facing extinction before the asteroid strike, and that mammals were already on the rise. Image credit: NASA/JPL-Caltech

Between the orbits of Mars and Jupiter lies the Solar System’s Main Asteroid Belt. Consisting of millions of objects that range in size from hundreds of kilometers in diameter (like Ceres and Vesta) to one kilometer or more, the Asteroid Belt has long been a source of fascination for astronomers. Initially, they wondered why the many objects that make it up did not come together to form a planet. But more recently, human beings have been eyeing the Asteroid Belt for other purposes.

Whereas most of our efforts are focused on research – in the hopes of shedding additional light on the history of the Solar System – others are looking to tap for its considerable wealth. With enough resources to last us indefinitely, there are many who want to begin mining it as soon as possible. Because of this, knowing exactly how long it would take for spaceships to get there and back is becoming a priority.

Distance from Earth:

The distance between the Asteroid Belt and Earth varies considerably depending on where we measure to. Based on its average distance from the Sun, the distance between Earth and the edge of the Belt that is closest to it can be said to be between 1.2 to 2.2 AUs, or 179.5 and 329 million km (111.5 and 204.43 million mi).

However, at any given time, part of the Asteroid Belt will be on the opposite side of the Sun, relative to Earth. From this vantage point, the distance between Earth and the Asteroid Blt ranges from 3.2 and 4.2 AU – 478.7 to 628.3 million km (297.45 to 390.4 million mi). To put that in perspective, the distance between Earth and the Asteroid Belt ranges between being slightly more than the distance between the Earth and the Sun (1 AU), to being the same as the distance between Earth and Jupiter (4.2 AU) when they are at their closest.

But of course, for reasons of fuel economy and time, asteroid miners and exploration missions are not about to take the long way! As such, we can safely assume that the distance between Earth and the Asteroid Belt when they are at their closest is the only measurement worth considering.

Past Missions:

The Asteroid Belt is so thinly populated that several unmanned spacecraft have been able to move through it on their way to the outer Solar System. In more recent years, missions to study larger Asteroid Belt objects have also used this to their advantage, navigating between the smaller objects to rendezvous with bodies like Ceres and Vesta. In fact, due to the low density of materials within the Belt, the odds of a probe running into an asteroid are now estimated at less than one in a billion.

The first spacecraft to make a journey through the asteroid belt was the Pioneer 10 spacecraft, which entered the region on July 16th, 1972 (a journey of 135 days). As part of its mission to Jupiter, the craft successfully navigated through the Belt and conducted a flyby of Jupiter (in December of 1973) before becoming the first spacecraft to achieve escape velocity from the Solar System.

At the time, there were concerns that the debris would pose a hazard to the Pioneer 10 space probe. But since that mission, 11 additional spacecraft have passed through the Asteroid Belt without incident. These included Pioneer 11, Voyager 1 and 2, Ulysses, Galileo, NEAR, Cassini, Stardust, New Horizons, the ESA’s Rosetta, and most recently, the Dawn spacecraft.

For the most part, these missions were part of missions to the outer Solar System, where opportunities to photograph and study asteroids were brief. Only the Dawn, NEAR and JAXA’s Hayabusa missions have studied asteroids for a protracted period in orbit and at the surface. Dawn explored Vesta from July 2011 to September 2012, and is currently orbiting Ceres (and sending back gravity data on the dwarf planet’s gravity) and is expected to remain there until 2017.

Fastest Mission to Date:

The fastest mission humanity has ever mounted was the New Horizons mission, which was launched from Earth on Jan. 19th, 2006. The mission began with a speedy launch aboard an Atlas V rocket, which accelerated it to a a speed of about 16.26 km per second (58,536 km/h; 36,373 mph). At this speed, the probe reached the Asteroid Belt by the following summer, and made a close approach to the tiny asteroid 132524 APL by June 13th, 2006 (145 days after launching).

However, even this pales in comparison to Voyager 1, which was launched on Sept. 5th, 1977 and reached the Asteroid Belt on Dec. 10th, 1977 – a total of 96 days. And then there was the Voyager 2 probe, which launched 15 days after Voyager 1 (on Sept. 20th), but still managed to arrive on the same date – which works out to a total travel time of 81 days.

Not bad as travel times go. At these speed, a spacecraft could make the trip to the Asteroid Belt, spend several weeks conducting research (or extracting ore), and then make it home in just over six months time. However, one has to take into account that in all these cases, the mission teams did not decelerate the probes to make a rendezvous with any asteroids.

Ergo, a mission to the Asteroid Belt would take longer as the craft would have to slow down to achieve orbital velocity. And they would also need some powerful engines of their own in order to make the trip home. This would drastically alter the size and weight of the spacecraft, which would inevitably mean it would be bigger, slower and a heck of a lot more expensive than anything we’ve sent so far.

Another possibility would be to use ionic propulsion (which is much more fuel efficient) and pick up a gravity assist by conducting a flyby of Mars – which is precisely what the Dawn mission did. However, even with a boost from Mars’ gravity, the Dawn mission still took over three years to reach the asteroid Vesta – launching on Sept. 27th, 2007, and arriving on July 16th, 2011, (a total of 3 years, 9 months, and 19 days). Not exactly good turnaround!

Proposed Future Methods:

A number of possibilities exist that could drastically reduce both travel time and fuel consumption to the Asteroid Belt, many of which are currently being considered for a number of different mission proposals. One possibility is to use spacecraft equipped with nuclear engines, a concept which NASA has been exploring for decades.

In a Nuclear Thermal Propulsion (NTP) rocket, uranium or deuterium reactions are used to heat liquid hydrogen inside a reactor, turning it into ionized hydrogen gas (plasma), which is then channeled through a rocket nozzle to generate thrust. A Nuclear Electric Propulsion (NEP) rocket involves the same basic reactor converting its heat and energy into electrical energy, which would then power an electrical engine.

In both cases, the rocket would rely on nuclear fission or fusion to generates propulsion rather than chemical propellants, which has been the mainstay of NASA and all other space agencies to date. According to NASA estimates, the most sophisticated NTP concept would have a maximum specific impulse of 5000 seconds (50 kN·s/kg).

Using this engine, NASA scientists estimate that it would take a spaceship only 90 days to get to Mars when the planet was at “opposition” – i.e. as close as 55,000,000 km from Earth. Adjusted for a distance of 1.2 AUs, that means that a ship equipped with a NTP/NEC propulsion system could make the trip in about 293 days (about nine months and three weeks). A little slow, but not bad considering the technology exists.

Another proposed method of interstellar travel comes in the form of the Radio Frequency (RF) Resonant Cavity Thruster, also known as the EM Drive. Originally proposed in 2001 by Roger K. Shawyer, a UK scientist who started Satellite Propulsion Research Ltd (SPR) to bring it to fruition, this drive is built around the idea that electromagnetic microwave cavities can allow for the direct conversion of electrical energy to thrust.

According to calculations based on the NASA prototype (which yielded a power estimate of 0.4 N/kilowatt), a spacecraft equipped with the EM drive could make the trip to Mars in just ten days. Adjusted for a trip to the Asteroid Belt, so a spacecraft equipped with an EM drive would take an estimated 32.5 days to reach the Asteroid Belt.

Impressive, yes? But of course, that is based on a concept that has yet to be proven. So let’s turn to yet another radical proposal, which is to use ships equipped with an antimatter engine. Created in particle accelerators, antimatter is the most dense fuel you could possibly use. When atoms of matter meet atoms of antimatter, they annihilate each other, releasing an incredible amount of energy in the process.

According to the NASA Institute for Advanced Concepts (NIAC), which is researching the technology, it would take just 10 milligrams of antimatter to propel a human mission to Mars in 45 days. Based on this estimate, a craft equipped with an antimatter engine and roughly twice as much fuel could make the trip to the Asteroid Belt in roughly 147 days. But of course, the sheer cost of creating antimatter – combined with the fact that an engine based on these principles is still theoretical at this point – makes it a distant prospect.

Basically, getting to the Asteroid Belt takes quite a bit of time, at least when it comes to the concepts we currently have available. Using theoretical propulsion concepts, we are able to cut down on the travel time, but it will take some time (and lots of money) before those concepts are a reality. However, compared to many other proposed missions – such as to Europa and Enceladus – the travel time is shorter, and the dividends quite clear.

As already stated, there are enough resources – in the form of minerals and volatiles – in the Asteroid Belt to last us indefinitely. And, should we someday find a way to cost-effective way to send spacecraft there rapidly, we could tap that wealth and begin to usher in an age of post-scarcity! But as with so many other proposals and mission concepts, it looks like we’ll have to wait for the time being.

We frequently call the HiRISE camera on board the Mars Reconnaissance Orbiter “our favorite camera” and for good reason. HiRISE, the High Resolution Imaging Science Experiment, is the largest and most powerful camera ever flown on a planetary mission, sending back incredibly beautiful, high-resolution images of Mars. While previous cameras on other Mars orbiters can identify objects about the size of a school bus, HiRISE brings it to human scale, imaging objects as small as 3 feet (1 meter) across.

The HiRISE team has just released more than 1,000 new observations of Mars for the Planetary Data System archive, showing a wide range of gullies, dunes, craters, geological layering and other features on the Red Planet. Take a look at some of the highlights (click on each image for higher resolution versions and more info):

MRO orbits at about 300 km above the Martian surface. The width of a HiRISE image covers about about 6 km, with a 1.2 km strip of color in the center. The length of the images can be up to 37 km. If you click on each of these images here, or go to the HiRISE website, you can see the full images in all their glory. To fully appreciate the images, you can download the special HiView application, which allows you to see the images in various formats.

HiRISE has been nicknamed “The People’s Camera“ because the team allows the public to choose specific targets for the camera to image. Check out the HiWISH page here if you’d like a certain spot on Mars imaged.

The lead image (the link to the image on the HiRISE site is here) shows a possible recurring slope lineae (RSL), mysterious dark streaks on slopes that appeared to ebb and flow over time. They darken and appear to flow down steep slopes during warm seasons, and then fade in cooler seasons. One possibility is this is evidence of liquid water present on Mars today. Some scientists said it could be a salty, briny liquid water flowing down the slopes. But a recent analysis says the RSLs show no mineralogical evidence for abundant liquid water or its by-products, and so it might be mechanisms other than the flow of water — such as the freeze and thaw of carbon dioxide frost — as being the major drivers of recent RSLs.

SpaceX Adopts Lessons Learned From Multiple Booster Landings – Test Fires Recovered 1st Stage: Videos

KENNEDY SPACE CENTER, FL – SpaceX founder Elon Musk’s daring dream of rocket recycling and reusability is getting closer and closer to reality with each passing day. After a breathtaking series of experimental flight tests aimed at safely landing the firms spent Falcon 9 first stages on land and at sea over the past half year the bold effort achieved another major milestone by just completing the first full duration test firing of one of those landed boosters.

On Thursday, July 28, SpaceX engineers successful conducted a full duration static engine test firing of the 156-foot-tall (47-meter) recovered Falcon 9 first stage booster while held down on a test stand at the company’s rocket development test facility in McGregor, Texas. The engines fired up for about two and a half minutes.

The SpaceX team has been perfecting the landing techniques by adopting lessons learned after each landing campaign attempt.

What are the lessons learned so far from the first stage landings and especially the hard landings? Are there any changes being made to the booster structure? How well did the landing burn scenario perform?

During SpaceX’s recent CRS-9 launch campaign media briefings at NASA’s Kennedy Space Center on July 18, I asked SpaceX VP Hans Koenigsmann for some insight.

“We learned a lot … from the landings,” Hans Koenigsmann, SpaceX vice president of Flight Reliability, told Universe Today during the recent media briefings for the SpaceX CRS-9 space station cargo resupply launch on July 18.

“There are no structural changes first of all.”

“The key thing is to protect the engines,” Koenigsmann elaborated, while they are in flight and “during reentry”.

The SpaceX Falcon 9 first stage is outfitted with four landing legs at the base and four grid fins at the top to conduct the landing attempts.

“In general I think the landing concept with the legs, and the number of burns and the way we perform those seems to work OK,” Koenigsmann told Universe Today.

After separating from the second stage at hypersonic speeds of up to some 4000 mph, the first stage engines are reignited to reverse course and do a boost backburn back to the landing site and slow the rocket down for a soft landing, via supersonic retropulsion.

Proper engine performance is critical to enabling a successful touchdown.

“The key thing is to protect the engines – and make sure that they start up well [in space during reentry],” Koenigsmann explained. “And in particular the hot trajectory, so to speak, like the ones that comes in after a fast payload, like the geo-transfer payload basically.”

“Those engines need to be protected so that they start up in the proper way. That’s something that we learned.”

Elon Musk’s goal is to radically slash the cost of launching rockets and access to space via rocket reuse – in a way that will one day lead to his vision of a ‘City on Mars.’

SpaceX hopes to refly a once flown booster later this year, sometime in the Fall, using the ocean landed Falcon from NASA’s CRS-8 space station mission launched in April, says Koenigsmann.

But the company first has to prove that the used vehicle can survive the extreme and unforgiving stresses of the violent spaceflight environment before they can relaunch it.

The July 28 test firing is part of that long life endurance testing and involved igniting all nine used first stage Merlin 1D engines housed at the base of a used landed rocket.

The Falcon 9 first stage generates over 1.71 million pounds of thrust when all nine Merlin engines fire up on the test stand for a duration of up to three minutes – the same as for an actual launch.

Watch the engine test in this SpaceX video:

The used 15 story Falcon booster had successfully carried out an intact soft landing on an ocean going platform after launching a Japanese commercial telecommunications satellite only two months ago on May 6 of this year.

Just 10 minutes after launching the JCSAT-14 telecom satellite to a Geostationary Transfer Orbit (GTO), the used first stage relit a first stage Merlin 1D engine.

It conducted a series of three recovery burns to maneuver the rocket to a designated landing spot at sea or on land and rapidly decelerate it from supersonic speeds for a propulsive soft landing, intact and upright using a quartet of landing legs that deploy in the final moments before a slow speed touchdown.

However, although the landing was upright and intact, this particular landing was also classed as a ‘hard landing’ because the booster landed at a higher velocity and Merlin 1D first stage engines did sustain heavy damage as seen in up close photos and acknowledged by Musk.

“Most recent rocket took max damage, due to v high entry velocity. Will be our life leader for ground tests to confirm others are good,” Musk tweeted at the time.

Nevertheless it all worked out spectacularly and this was the first one to be recovered from the much more demanding, high velocity trajectory delivering a satellite to GTO.

Indeed prior to liftoff, Musk had openly doubted a successful landing outcome, since this first stage was flying faster and at a higher altitude at the time of separation from the second stage and thus was much more difficult to slow down and maneuver back to the ocean based platform compared to ISS missions, for example.

So although this one cannot be reflown, it still serves another great purpose for engineers seeking to determining the longevity of the booster and its various components – as now audaciously demonstrated by the July 28 engine test stand firing.

“We learned a lot even on the missions where things go wrong with the landing, everything goes well on the main mission of course,” said Koenigsmann.

Altogether SpaceX has successfully soft landed and recovered five of their first stage Falcon 9 boosters intact and upright since the history making first ever land landing took place just seven months ago in December 2015 at Cape Canaveral Air Force Station in Florida.

The most recent launch and landing occurred last week on July 18, 2016 during the dramatic midnight blastoff of the SpaceX CRS-9 commercial cargo resupply mission to the International Space Station (ISS) under contract for NASA.

See the stupendous events unfold in up close photos and videos herein.

CRS-9 marks only the second time SpaceX has attempted a land landing of the 15 story tall first stage booster back at Cape Canaveral Air Force Station – at the location called Landing Zone 1 (LZ 1).

Watch this exquisitely detailed up close video showing the CRS-9 first stage landing at LZ 1, as shot by space colleague Jeff Seibert from the ITL causeway at CCAFS- which dramatically concluded with multiple shockingly loud sonic booms rocketing across the Space Coast and far beyond and waking hordes of sleepers:

Video caption: This was the second terrestrial landing of a SpaceX Falcon 9 booster on July 18, 2016. It had just launched the CRS9 Dragon mission towards the ISS. The landing took place at LZ1, formerly known as Pad 13, located on CCAFS and caused a triple sonic boom heard 50 miles away. Credit: Jeff Seibert

The history making first ever ground landing successfully took place at Landing Zone 1 (LZ 1) on Dec. 22, 2015 as part of the ORBCOMM-2 mission. Landing Zone 1 is built on the former site of Space Launch Complex 13, a U.S. Air Force rocket and missile testing range.

SpaceX also successfully recovered first stages three times in a row at sea this year on an ocean going drone ship barge using the company’s OCISLY Autonomous Spaceport Drone Ship (ASDS) on April 8, May 6 and May 27.

OCISLY is generally stationed approximately 400 miles (650 kilometers) off shore and east of Cape Canaveral, Florida in the Atlantic Ocean. The barge arrives back in port at Port Canaveral several days after the landing, depending on many factors like weather, port permission and the state of the rocket.

However while trying to extend the touchdown streak to 4 in a row during the latest drone ship landing attempt following the June 15 Eutelsat telecom launch to GTO, the booster basically crashed because it descended too quickly due to insufficient thrust from the Merlin descent engines.

The rocket apparently ran out of liquid oxygen fuel in the final moments before touchdown, hit hard, tipped over and pancaked onto the deck.

“Looks like early liquid oxygen depletion caused engine shutdown just above the deck,” Musk explained via twitter at the time.

“Looks like thrust was low on 1 of 3 landing engines. High g landings v sensitive to all engines operating at max.”

“We learned a lot even on the mission where things go wrong with the landing,” Koenigsmann explained. “Everything goes well on the main mission of course.”

“That’s actually something where you have successful deploy and the landing doesn’t quite work- and yet its the landing that gets all the attention.”

“But even on those landings we learned a lot. In particular on the last landing [from Eutelsat launch] we learned a lot.”

“We believe we found a way to operationally protect these engines and to make it safer for them to start up – and to come up to full thrust and stay at full thrust.”

What exactly does “protecting the engines” mean “in flight?”

“Yes I mean protecting the engines during reentry,” Koenigsmann told me.

“That’s when the engines get hot. We enter with the engines facing the flow. So its basically the engines directly exposed to the hot flow. And that’s when you need to protect the engines and the gases and liquids that are in the engines. To make sure that nothing boils off and does funny things.”

“So all in all these series of drone ship landings has been extremely successful, even when we didn’t recover all the first stages [fully intact].”

CAPE CANAVERAL AIR FORCE STATION, FL — Riding atop the crackling roar of an Atlas V rocket, a clandestine surveillance satellite for our nation’s spy masters was carried aloft by a powerful booster from the Florida space coast to an undisclosed orbit at breakfast time today, Thursday, July 28.

The United Launch Alliance (ULA) Atlas V rocket carrying the NROL-61 surveillance satellite for the National Reconnaissance Office (NRO) lifted off from Space Launch Complex-41 right at the appointed time of 8:37 a.m. EDT this morning with approximately 1.5 million pounds of thrust.

The top secret NROL-61 satellite bolted on top and inside the 4 meter diameter nose cone was launched in support of US national defense and is vital to US national security.

“Thank you to the entire mission team for years of hard work and collaboration on today’s successful launch of NROL-61. We are proud the U.S. Air Force and NRO Office of Space Launch have entrusted ULA with delivering this critical asset for our nation’s security,” said Laura Maginnis, ULA vice president of Custom Services, in a statement.

“Our continued one launch at a time focus and exceptional teamwork make launches like today’s successful.”

The launch was webcast live by ULA and featured video recorded call in questions about spaceflight from the general public – especially children!

The rocket roared off pad 41 atop an ever expanding plume of smoke and ash into a brilliant and cloudless blue sky under absolutely ideal weather conditions with clear lines of sight enjoyed by hordes of spectators gathered here from near and far, and lining the space coast beaches and surrounding viewing areas.

Many local area hotels were packed with space enthusiasts hoping for a space spectacular at this unusually convenient launch time – and they were not disappointed!!

Because the Atlas rocket was equipped with a pair of powerful solid rocket boosters to augment its liftoff thrust, the smoke plume was visible for as long as we could see it.

The rocket soon arced over, racing southeasterly to orbit and towards the African continent.

Virtually everything about the clandestine payload, its mission, purpose and goals are classified top secret on a mission of vital importance to America’s national security and defense needs.

The NRO is the government agency that runs a vast fleet of powerful orbital assets hosting a multitude of the most advanced, wide ranging and top secret capabilities.

The most recent NRO payload, known as NROL 37, was just launched by ULA last month on their Delta IV Heavy – the most powerful rocket in the world on June 11 – read my story here.

The venerable ULA Atlas V rocket sports a 100% record of launch success and its unusual for technical issues to hold up a launch. The ever changeable Florida weather is another matter entirely.

The NROL-61 mission counts as ULA’s sixth launch of 2016 and the 109th overall since the company was founded in 2006.

The 20 story tall Atlas V launched in its 421 configuration – the same as what will be used for manned launches with the crewed Boeing ‘Starliner’ space taxi carrying astronaut crews to the International Space Station.
This was the sixth Atlas V to launch in the 421 configuration.

The Atlas 421 vehicle includes a 4-meter diameter Extra Extended Payload Fairing (XEPF) payload fairing and two solid rocket boosters that augment the first stage. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine and the Centaur upper stage was powered by the Aerojet Rocketdyne RL10C-1 engine.

The RD-180 burns RP-1 (Rocket Propellant-1 or highly purified kerosene) and liquid oxygen and delivers 860,200 lb of thrust at sea level.

The strap on solids deliver approximately 500,000 pounds of thrust.

The solids were jettisoned about 2 minutes after liftoff.

Virtually everything about the clandestine payload, its mission, purpose and goals are classified top secret.

The NRO is the government agency that runs a vast fleet of powerful orbital assets hosting a multitude of the most advanced, wide ranging and top secret capabilities.

The possible roles for the reconnaissance payload include signals intelligence, eavesdropping, imaging and spectroscopic observations, early missile warnings and much more.

The NRO was formed in response to the Soviet launch of Sputnik and secretly created on September 6, 1961.

“The purpose is overseeing all satellite and overflight reconnaissance projects whether overt or covert. The existence of the organization is no longer classified today, but we’re still pressing to perform the functions necessary to keep American citizens safe,” according to the official NRO website.

MICHOUD ASSEMBLY FACILITY, NEW ORLEANS, LA – NASA has just finished welding together the very first fuel tank for America’s humongous Space Launch System (SLS) deep space rocket currently under development – and Universe Today had an exclusive up close look at the liquid hydrogen (LH2) test tank shortly after its birth as well as the first flight tank, during a tour of NASA’s New Orleans rocket manufacturing facility on Friday, July 22, shortly after completion of the milestone assembly operation.

“We have just finished welding the first liquid hydrogen qualification tank article …. and are in the middle of production welding of the first liquid hydrogen flight hardware tank [for SLS-1] in the big Vertical Assembly Center welder!” explained Patrick Whipps, NASA SLS Stages Element Manager, in an exclusive hardware tour and interview with Universe Today on July 22, 2016 at NASA’s Michoud Assembly Facility (MAF) in New Orleans.

“We are literally putting the SLS rocket hardware together here at last. All five elements to put the SLS stages together [at Michoud].”

This first fully welded SLS liquid hydrogen tank is known as a ‘qualification test article’ and it was assembled using basically the same components and processing procedures as an actual flight tank, says Whipps.

“We just completed the liquid hydrogen qualification tank article and lifted it out of the welding machine and put it into some cradles. We will put it into a newly designed straddle carrier article next week to transport it around safely and reliably for further work.”

And welding of the liquid hydrogen flight tank is moving along well.

“We will be complete with all SLS core stage flight tank welding in the VAC by the end of September,” added Jackie Nesselroad, SLS Boeing manager at Michoud. “It’s coming up very quickly!”

“The welding of the forward dome to barrel 1 on the liquid hydrogen flight tank is complete. And we are doing phased array ultrasonic testing right now!”

SLS is the most powerful booster the world has even seen and one day soon will propel NASA astronauts in the agency’s Orion crew capsule on exciting missions of exploration to deep space destinations including the Moon, Asteroids and Mars – venturing further out than humans ever have before!

The LH2 ‘qualification test article’ was welded together using the world’s largest welder – known as the Vertical Assembly Center, or VAC, at Michoud.

And it’s a giant! – measuring approximately 130-feet in length and 27.6 feet (8.4 m) in diameter.

See my exclusive up close photos herein documenting the newly completed tank as the first media to visit the first SLS tank. I saw the big tank shortly after it was carefully lifted out of the welder and placed horizontally on a storage cradle on Michoud’s factory floor.

Finishing its assembly after years of meticulous planning and hard work paves the path to enabling the maiden test launch of the SLS heavy lifter in the fall of 2018 from the Kennedy Space Center (KSC) in Florida.

The qual test article is the immediate precursor to the actual first LH2 flight tank now being welded.

“We will finish welding the liquid hydrogen and liquid oxygen flight tanks by September,” Whipps told Universe Today.

Technicians assembled the LH2 tank by feeding the individual metallic components into NASA’s gigantic “Welding Wonder” machine – as its affectionately known – at Michoud, thus creating a rigid 13 story tall structure.

The welding work was just completed this past week on the massive silver colored structure. It was removed from the VAC welder and placed horizontally on a cradle.

I watched along as the team was also already hard at work fabricating SLS’s first liquid hydrogen flight article tank in the VAC, right beside the qualification tank resting on the floor.

Welding of the other big fuel tank, the liquid oxygen (LOX) qualification and flight article tanks will follow quickly inside the impressive ‘Welding Wonder’ machine, Nesselroad explained.

The LH2 and LOX tanks sit on top of one another inside the SLS outer skin.

The SLS core stage – or first stage – is mostly comprised of the liquid hydrogen and liquid oxygen cryogenic fuel storage tanks which store the rocket propellants at super chilled temperatures. Boeing is the prime contractor for the SLS core stage.

To prove that the new welding machines would work as designed, NASA opted “for a 3 stage assembly philosophy,” Whipps explained.

Engineers first “welded confidence articles for each of the tank sections” to prove out the welding techniques “and establish a learning curve for the team and test out the software and new weld tools. We learned a lot from the weld confidence articles!”

“On the heels of that followed the qualification weld articles” for tank loads testing.

“The qualification articles are as ‘flight-like’ as we can get them! With the expectation that there are still some tweaks coming.”

“And finally that leads into our flight hardware production welding and manufacturing the actual flight unit tanks for launches.”

“All the confidence articles and the LH2 qualification article are complete!”

What’s the next step for the LH2 tank?

The test article tank will be outfitted with special sensors and simulators attached to each end to record reams of important engineering data, thereby extending it to about 185 feet in length.

Thereafter it will loaded onto the Pegasus barge and shipped to NASA’s Marshall Space Flight Center in Huntsville, Alabama, for structural loads testing on one of two new test stands currently under construction for the tanks. The tests are done to prove that the tanks can withstand the extreme stresses of spaceflight and safely carry our astronauts to space.

“We are manufacturing the simulators for each of the SLS elements now for destructive tests – for shipment to Marshall. It will test all the stress modes, and finally to failure to see the process margins.”

The SLS core stage builds on heritage from NASA’s Space Shuttle Program and is based on the shuttle’s External Tank (ET). All 135 ET flight units were built at Michoud during the thirty year long shuttle program by Lockheed Martin.

“We saved billions of dollars and years of development effort vs. starting from a clean sheet of paper design, by taking aspects of the shuttle … and created an External Tank type generic structure – with the forward avionics on top and the complex engine section with 4 engines (vs. 3 for shuttle) on the bottom,” Whipps elaborated.

“This is truly an engineering marvel like the External Tank was – with its strength that it had and carrying the weight that it did. If you made our ET the equivalent of a Coke can, our thickness was about 1/5 of a coke can.”

“It’s a tremendous engineering job. But the ullage pressures in the LOX and LH2 tanks are significantly more and the systems running down the side of the SLS tank are much more sophisticated. Its all significantly more complex with the feed lines than what we did for the ET. But we brought forward the aspects and designs that let us save time and money and we knew were effective and reliable.”

The SLS core stage is comprised of five major structures: the forward skirt, the liquid oxygen tank (LOX), the intertank, the liquid hydrogen tank (LH2) and the engine section.

The LH2 and LOX tanks feed the cryogenic propellants into the first stage engine propulsion section which is powered by a quartet of RS-25 engines – modified space shuttle main engines (SSMEs) – and a pair of enhanced five segment solid rocket boosters (SRBs) also derived from the shuttles four segment boosters.

The tanks are assembled by joining previously manufactured dome, ring and barrel components together in the Vertical Assembly Center by a process known as friction stir welding. The rings connect and provide stiffness between the domes and barrels.

The LH2 tank is the largest major part of the SLS core stage. It holds 537,000 gallons of super chilled liquid hydrogen. It is comprised of 5 barrels, 2 domes, and 2 rings.

The LOX tank holds 196,000 pounds of liquid oxygen. It is assembled from 2 barrels, 2 domes, and 2 rings and measures over 50 feet long.

The material of construction of the tanks has changed compared to the ET.

“The tanks are constructed of a material called the Aluminum 2219 alloy,” said Whipps. “It’s a ubiquosly used aerospace alloy with some copper but no lithium, unlike the shuttle superlightweight ET tanks that used Aluminum 2195. The 2219 has been a success story for the welding. This alloy is heavier but does not affect our payload potential.”

“The intertanks are the only non welded structure. They are bolted together and we are manufacturing them also. It’s much heavier and thicker.”

Overall, the SLS core stage towers over 212 feet (64.6 meters) tall and sports a diameter of 27.6 feet (8.4 m).

NASA’s Vehicle Assembly Center is the world’s largest robotic weld tool. The domes and barrels are assembled from smaller panels and piece parts using other dedicated robotic welding machines at Michoud.

The total weight of the whole core stage empty is 188,000 pounds and 2.3 million pounds when fully loaded with propellant. The empty ET weighed some 55,000 pounds.

Considering that the entire Shuttle ET was 154-feet long, the 130-foot long LH2 tank alone isn’t much smaller and gives perspective on just how big it really is as the largest rocket fuel tank ever built.

“So far all the parts of the SLS rocket are coming along well.”

“The Michoud SLS workforce totals about 1000 to 1500 people between NASA and the contractors.”

Every fuel tank welded together from now on after this series of confidence and qualification LOX and LH2 tanks will be actual flight article tanks for SLS launches.

“There are no plans to weld another qualification tank after this,” Nesselroad confirmed to me.

What’s ahead for the SLS-2 core stage?

“We start building the second SLS flight tanks in October of this year – 2016!” Nesselroad stated.

The world’s largest welder was specifically designed to manufacture the core stage of the world’s most powerful rocket – NASA’s SLS.

The Vertical Assembly Center welder was officially opened for business at NASA’s Michoud Assembly Facility in New Orleans on Friday, Sept. 12, 2014.

NASA Administrator Charles Bolden was personally on hand for the ribbon-cutting ceremony at the base of the huge VAC welder.

The state-of-the-art welding giant stands 170 feet tall and 78 feet wide. It complements the world-class welding toolkit being used to assemble various pieces of the SLS core stage including the domes, rings and barrels that have been previously manufactured.

The maiden test flight of the SLS/Orion is targeted for no later than November 2018 and will be configured in its initial 70-metric-ton (77-ton) Block 1 configuration with a liftoff thrust of 8.4 million pounds – more powerful than NASA’s Saturn V moon landing rocket.

Although the SLS-1 flight in 2018 will be uncrewed, NASA plans to launch astronauts on the SLS-2/EM-2 mission slated for the 2021 to 2023 timeframe.

The exact launch dates fully depend on the budget NASA receives from Congress and who is elected President in the November 2016 election – and whether they maintain or modify NASA’s objectives.

“If we can keep our focus and keep delivering, and deliver to the schedules, the budgets and the promise of what we’ve got, I think we’ve got a very capable vision that actually moves the nation very far forward in moving human presence into space,” said William Gerstenmaier, associate administrator for the Human Exploration and Operations Mission Directorate at NASA Headquarters in Washington, during the post QM-2 SRB test media briefing in Utah last month.

“This is a very capable system. It’s not built for just one or two flights. It is actually built for multiple decades of use that will enable us to eventually allow humans to go to Mars in the 2030s.”

Looking for a way to commemorate the 47th anniversary of the Apollo 11 mission landing on the Moon? Here are a few different ways look back on this historic event and take advantage of advances in technology or new data.

Below is a video that uses data from the Lunar Reconnaissance Orbiter and its amazing suite of cameras, offering a side-by-side view of Apollo 11’s descent, comparing footage originally shot from the Eagle lunar module’s window with views created from reconstructed LRO imagery. This is a fun way to re-live the landing — 1202 alarms and all — while seeing high definition views of the lunar surface.

The National Air and Space Museum in Washington, DC has a special way to mark the Apollo 11 anniversary. They have posted online high-resolution 3-D scans of the command module Columbia, the spacecraft that carried astronauts Neil Armstrong, Buzz Aldrin and Michael Collins to the Moon. This very detailed model allows you to explore the entire spacecraft’s interior, which, if you’ve ever visited the Air & Space museum and seen Columbia in person, you probably know is a tremendous ‘upgrade,’ since you can only see a portion of the interior through couple of small hatches and windows. The Smithsonian is also making the data files of the model available for download so it can be 3-D printed or viewed with virtual-reality goggles. Find all the details here.

While 3D scanning the Apollo 11 Command Module, museum staff uncovered writing on the interior walls of the module.The main control panel of the spacecraft contains essential switches and indicators that had to be referred to and operated during the most crucial aspects of the flight. Numbers and references written by hand onto the panel can be checked against the audio and written transcripts from the mission to provide a more vivid picture of just what transpired.

Here’s a remastered version of the original mission video as aired in July 1969 depicting the Apollo 11 astronauts conducting several tasks during the moonwalk (EVA) operations on the surface of the moon, which lasted approximately 2.5 hours.

If you’re pressed for time, here’s a quick look at the entire Apollo 11 mission, all in just 100 seconds from Spacecraft Films:

Here’s a very cool detailed look at the Apollo 11 launch in ultra-slow motion, with narration:

Enjoy, and happy anniversary!
