America’s first ever mission designed to retrieve samples from the surface of an asteroid and return them to Earth – OSIRIS-Rex – has arrived at its Florida launch base for processing to get ready for blastoff barely three and one half months from today.
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.
OSIRIS-REx was flown to NASA’s Kennedy Space Center from prime contractor Lockheed Martin’s facility near Denver, Colorado via Buckley Air Force Base. It arrived safely inside its shipping container on Friday, May 20 aboard an Air Force C-17 at the Shuttle Landing Facility.
It was soon offloaded and transported to Kennedy’s Payloads Hazardous Servicing Facility, or PHSF. OSIRIS-REx came out of the shipping container today, Saturday, May 21.

A busy first week of processing starts Monday.
NASA officials say it will go onto a rotation fixture on Monday, May 23, have a spin test May 24-25. It then will be hoisted onto a dolly May 26 for other upcoming activities. A partial solar array deployment test is scheduled on May 31.
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 mission.
The spacecraft will reach Bennu in 2018. Once within three miles of the asteroid, the spacecraft will begin six months of comprehensive surface mapping of the carbonaceous asteroid.
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.
OSIRIS-REx will gather rocks and soil and bring at least a 60-gram (2.1-ounce) sample back to Earth in 2023 for study by researchers here with all the most sophisticated science instruments available.
The mission will help scientists investigate how planets formed and how life began, as well as improve our understanding of asteroids that could impact 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,” says NASA.
OSIRIS-Rex will return the largest sample from space since the American and Soviet Union’s moon landing missions of the 1970s.

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.
OSIRIS-REx will launch on a United Launch Alliance (ULA) Atlas V rocket similar to this launch carrying the GPS IIF-12 mission which lifted off at 8:38 a.m. EST on Feb. 5, 2016 from Space Launch Complex 41 on Cape Canaveral Air Force Station, Fla. Credit: Ken Kremer/kenkremer.com

The next Orion crew module in line to launch to space on NASA’s Exploration Mission-1 (EM-1) has passed a critical series of proof pressure tests which confirm the effectiveness of the welds holding the spacecraft structure together.
Any leaks occurring in flight could threaten the astronauts lives.
Engineers and technicians conducted the pressure tests on the Orion EM-1 pressure vessel, which was welded together at NASA’s Michoud Assembly Facility in New Orleans and then shipped to NASA’s Kennedy Space Center in Florida just 3 months ago.
The pressure vessel is the structural backbone for the vehicles that will launch American astronauts to deep space destinations.
“This is the first mission where the Orion spacecraft will be integrated with the large Space Launch System rocket. Orion is the vehicle that’s going to take astronauts to deep space,” NASA Orion program manager Scott Wilson told Universe Today.
“The tests confirmed that the weld points of the underlying structure will contain and protect astronauts during the launch, in-space, re-entry and landing phases on the Exploration Mission 1 (EM-1), when the spacecraft performs its first uncrewed test flight atop the Space Launch System rocket,” according to a NASA statement.
After flying to KSC on Feb 1, 2016 inside NASA’s unique Super Guppy aircraft, this “new and improved” Orion EM-1 pressure vessel was moved to the Neil Armstrong Operations and Checkout (O&C) Building for final assembly by prime contractor Lockheed Martin into a flight worthy vehicle.

Since then, technicians have worked to meticulously attach hundreds of strain gauges to the interior and exterior surfaces of the vehicle to prepare for the pressure tests.
The strain gauges provide real time data to the analysts monitoring the changes during the pressurization.
Orion was moved to a test stand inside the proof pressure cell high bay and locked inside behind large doors.
Lockheed Martin engineers then incrementally increased the pressure in the proof testing cell in a series of steps over two days. They carefully monitored the results along the way and how the spacecraft reacted to the stresses induced by the pressure increases.
The maximum pressure reached was 1.25 times normal atmospheric pressure – which exceeds the maximum pressure it is expected to encounter on orbit.
“We are very pleased with the performance of the spacecraft during proof pressure testing,” said Scott Wilson, NASA manager of production operations for the Orion Program.
“The successful completion of this test represents another major step forward in our march toward completing the EM-1 spacecraft, and ultimately, our crewed missions to deep space.”

With the pressure testing satisfactorily completed, technicians will move Orion back to birdcage assembly stand for the “intricate work of attaching hundreds of brackets to the vessel’s exterior to hold the tubing for the vehicle’s hydraulics and other systems.”
To prepare for launch in 2018, engineers and technicians from NASA and prime contractor Lockheed Martin will spend the next two years meticulously installing all the systems amounting to over 100,000 components and gear required for flight.
This particular ‘Lunar Orion’ crew module is intended for blastoff to the Moon in 2018 on NASA’s Exploration Mission-1 (EM-1) atop the agency’s mammoth new Space Launch System (SLS) rocket, simultaneously under development. The pressurized crew module serves as the living quarters for the astronauts comprising up to four crew members.

EM-1 itself is a ‘proving ground’ mission that will fly an unmanned Orion thousands of miles beyond the Moon, further than any human capable vehicle, and back to Earth, over the course of a three-week mission.
The 2018 launch of NASA’s Orion on the unpiloted EM-1 mission counts as the first joint flight of SLS and Orion, and the first flight of a human rated spacecraft to deep space since the Apollo Moon landing era ended more than 4 decades ago.
Orion is designed to send astronauts deeper into space than ever before, including missions to the Moon, asteroids and the Red Planet.

SpaceX announced plans today, April 27, for the first ever private mission to Mars which involves sending an uncrewed version of the firms Dragon spacecraft to accomplish a propulsive soft landing – and to launch it as soon as 2018 including certain technical assistance from NASA.
Under a newly signed space act agreement with NASA, the agency will provide technical support to SpaceX with respect to Mars landing technologies for the new spacecraft known as a ‘Red Dragon’ and possibly also for science activities.
“SpaceX is planning to send Dragons to Mars as early as 2018,” the company posted in a brief announcement today on Facebook and other social media about the history making endeavor.
The 2018 commercial Mars mission involves launching the ‘Red Dragon’ – also known as Dragon 2 – on the SpaceX Falcon Heavy rocket from Launch Pad 39A at NASA’s Kennedy Space Center in Florida. It’s a prelude to eventual human missions.
The Red Dragon initiative is a commercial endeavor that’s privately funded by SpaceX and does not include any funding from NASA. The agreement with NASA specifically states there is “no-exchange-of-funds.”
As of today, the identity and scope of any potential science payload is undefined and yet to be determined.
Hopefully it will include a diverse suite of exciting research instruments from NASA, or other entities, such as high powered cameras and spectrometers characterizing the Martian surface, atmosphere and environment.
SpaceX CEO and billionaire founder Elon Musk has previously stated his space exploration goals involve helping to create a Mars colony which would ultimately lead to establishing a human ‘City on Mars.’
Musk is also moving full speed ahead with his goal of radically slashing the cost of access to space by recovering a pair of SpaceX Falcon 9 first stage boosters via successful upright propulsive landings on land and at sea – earlier this month and in Dec. 2015.

The 2018 liftoff campaign marks a significant step towards fulfilling Musk’s Red Planet vision. But we’ll have to wait another 5 months for concrete details.
“Red Dragon missions to Mars will also help inform the overall Mars colonization architecture that SpaceX will reveal later this year,” SpaceX noted.
Musk plans to reveal the details of the Mars colonization architecture later this year at the International Astronautical Congress (IAC) being held in Guadalajara, Mexico from September 26 to 30, 2016.
Landing on Mars is not easy. To date only NASA has successfully soft landed probes on Mars that returned significant volumes of useful science data.
In the meantime a few details about the SpaceX Red Dragon have emerged.
The main goal is to propulsively land something 5-10 times the size of anything previously landed before.
“These missions will help demonstrate the technologies needed to land large payloads propulsively on Mars,” SpaceX further posted.

As part of NASA’s agency wide goal to send American astronauts on a human ‘Journey to Mars’ in the 2030s, NASA will work with SpaceX on some aspects of the Red Dragon initiative to further the agency’s efforts.
According to an amended space act agreement signed yesterday jointly by NASA and SpaceX officials – that originally dates back to November 2014 – this mainly involves technical support from NASA and exchanging entry, descent and landing (EDL) technology, deep space communications, telemetry and navigation support, hardware advice, and interplanetary mission and planetary protection advice and consultation.
“We’re particularly excited about an upcoming SpaceX project that would build upon a current “no-exchange-of-funds” agreement we have with the company,” NASA Deputy Administrator Dava Newman wrote in a NASA blog post today.
“In exchange for Martian entry, descent, and landing data from SpaceX, NASA will offer technical support for the firm’s plan to attempt to land an uncrewed Dragon 2 spacecraft on Mars.”
“This collaboration could provide valuable entry, descent and landing data to NASA for our journey to Mars, while providing support to American industry,” NASA noted in a statement.
The amended agreement with NASA also makes mention of sharing “Mars Science Data.”
As of today, the identity, scope and weight of any potential science payload is undefined and yet to be determined.
Perhaps it could involve a suite of science instruments from NASA, or other entities, such as cameras and spectrometers characterizing various aspects of the Martian environment.
In the case of NASA, the joint agreement states that data collected with NASA assets is to be released within a period not to exceed 6 months and published where practical in scientific journals.
The Red Dragon envisioned for blastoff to the Red Planet as soon as 2018 would launch with no crew on board on a critical path finding test flight that would eventually pave the way for sending humans to Mars – and elsewhere in the solar system.
“Red Dragon Mars mission is the first test flight,” said Musk.
“Dragon 2 is designed to be able to land anywhere in the solar system.”
However, the Dragon 2 alone is far too small for a round trip mission to Mars – lasting some three years or more.
“Wouldn’t be fun for longer journeys. Internal volume ~size of SUV.”
Furthermore, for crewed missions it would also have to be supplemented with additional modules for habitation, propulsion, cargo, science, communications and more. Think ‘The Martian’ movie to get a realistic idea of the complexity and time involved.
Red Dragon’s blastoff from KSC pad 39A is slated to take place during the Mars launch window opening during April and May 2018.
The inaugural liftoff of the Falcon Heavy is currently scheduled for late 2016 after several years postponement.
If all goes well, Red Dragon could travel to Mars at roughly the same time as NASA’s next Mission to Mars – namely the InSight science lander, which will study the planets deep interior with a package of seismometer and heat flow instruments.
InSight’s launch on a United Launch Alliance Atlas V is targeting a launch window that begins May 5, 2018, with a Mars landing scheduled for Nov. 26, 2018. Liftoff was delayed from this year due to a flaw in the French-built seismometer.

Whoever wants to land on Mars also has to factor in the relevant International treaties regarding ‘Planetary Protection’ requirements.
Wherever the possibility for life exists, the worlds space agency’s who are treaty signatories, including NASA, are bound to adhere to protocols limiting contamination by life forms from Earth.
SpaceX intends to take planetary protection seriously. Under the joint agreement, SpaceX is working with relevant NASA officials to ensure proper planetary protection procedures are followed. One of the areas of collaboration with NASA is for them to advise SpaceX in the development a Planetary Protection Plan (PPP) and assist with the implementation of a PPP including identifying existing software/tools.
Red Dragon is derived from the SpaceX crew Dragon vehicle currently being developed under contract for NASA’s Commercial Crew Program (CCP) to transport American astronauts back and forth to low Earth orbit and the International Space Station (ISS).
SpaceX and Boeing were awarded commercial crew contracts from NASA back in September 2014.
Both firms hope to launch unmanned and manned test flights of their SpaceX Crew Dragon and Boeing CST-100 Starliner spacecraft to the ISS starting sometime in 2017.
The crew Dragon is also an advanced descendent of the original unmanned cargo Dragon that has ferried tons of science experiments and essential supplies to the ISS since 2012.

To enable propulsive landings, SpaceX recently conducted hover tests using a Dragon 2 equipped with eight side-mounted SuperDraco engines at their development testing facility in McGregor, TX.
These are “Key for Mars landing,” SpaceX wrote.
“We are closer than ever before to sending American astronauts to Mars than anyone, anywhere, at any time has ever been,” Newman states.

We like to focus on successful space missions and celebrate what those successes add to our knowledge. But, obviously, not all missions are completely successful. And since some missions are at such huge distances from Earth, their fate can remain a mystery.
This was true of the Beagle 2 Lander, until recently.
The Beagle 2 was a UK contribution to the ESA’s Mars Express mission, launched in 2003. Mars Express consisted of two components; the Mars Express Orbiter and the Beagle 2 Lander. The mission arrived at Mars in December 2003, when the Beagle 2 separated from the orbiter and landed on the Martian surface.
Beagle 2’s destination was Isidis Planitia, a vast sedimentary basin. Beagle 2 was supposed to operate for 180 days, with a possible extension up to one Martian year. But the ESA was unable to contact the lander after several attempts, and in February 2004, the ESA declared the mission lost.
The Beagle 2, named after the ship that Darwin took on his famous voyage, had some solid science goals in mind. It was going to study the geology, mineralogy, and the geochemistry of the landing site, and also the physical properties of the atmosphere and Mars’ surface. It was also going to study the Martian meteorology and climate, and search for biosignatures. But all that was lost.
There was lots of conjecture, but the Beagle 2’s fate was a mystery.
Now, thanks to a new method of ‘stacking and matching’ photos of the Martian surface, which results in higher resolution images than previously possible, the likely fate of the Beagle 2 is known. It appears that the spacecraft landed softly as planned, but that solar panels failed to deploy properly. This not only starved the lander of electrical power, but blocked the craft’s antenna from functioning. This is why no signal was ever received from Beagle 2.

It took quite a bit of sleuthing to find the Beagle 2. The MRO has used its High Resolution Imaging Science Experiment (HiRise) camera to search for other craft on the surface of Mars, but the Beagle 2 was harder to find. It never sent even a brief signal after touchdown, which would have made it much easier to locate.
Adding to the difficulty is the huge landing area the Beagle 2 had. Beagle 2’s landing site at the time of its launch was an ellipse 170 km by 100 km in the Isidis Planitia. That’s an enormous area in which to locate a spacecraft that’s less than a few meters across once deployed, with a camera that has an image scale of about 0.2m, (10 inches).
The MRO has been using its HiRise to look for Beagle 2 since it was lost. As it went about the business of its science objectives, it captured occasional images of the Beagle 2’s landing site. Eventually, the lander was identified by Michael Croon, a former member of the ESA’s Mars Express Orbiter team. In HiRise images from February 2013 and June 2014, Croon found visual evidence of the lander and its entry and descent components.
The puzzling thing was that the image seemed to shift around in different photos. This could be because the lander deployed its solar panels like flower petals arranged around the center. The panels will reflect light differently in different lighting conditions, which could make the lander appear to change location in subsequent photos. If Beagle 2 is sitting on an uneven surface, that could add to the illusion.
The HiRise images are consistent with the idea that the panels failed to deploy, and that also makes sense if the panels blocked the antenna from operating. It’s also possible that the sun glinting off the panels only makes it appear that not all of them opened.

But what’s bad news for Beagle 2 is good news for the human endeavour to study Mars. The new technique of combining images of the surface of Mars yields photos with 5 times the resolution that MRO can provide. This will make selecting landing sites for future missions much easier, and will also contribute to the science objectives of the MRO itself.

The Mars Express Orbiter is still in operation above Mars, and has been for over 12 years. Among its achievements are the detection of water ice in Mars’ South Polar cap and the discovery of methane in the atmosphere of Mars. The orbiter also performed the closest-ever flyby of Mars’ moon Phobos.

Every year, the NASA Innovative Advanced Concepts (NIAC) program puts out the call to the general public, hoping to find better or entirely new aerospace architectures, systems, or mission ideas. As part of the Space Technology Mission Directorate, this program has been in operation since 1998, serving as a high-level entry point to entrepreneurs, innovators and researchers who want to contribute to human space exploration.
This year, thirteen concepts were chosen for Phase I of the NIAC program, ranging from reprogrammed microorganisms for Mars, a two-dimensional spacecraft that could de-orbit space debris, an analog rover for extreme environments, a robot that turn asteroids into spacecraft, and a next-generation exoplanet hunter. These proposals were awarded $100,000 each for a nine month period to assess the feasibility of their concept.
Engineers at NASA’s Johnson Space Center in Houston used the space station’s high tech robotic arm to pluck the small module known as the Bigelow Expandable Activity Module (BEAM) out from the unpressurized rear truck section of the recently arrived SpaceX Dragon cargo freighter, and added it onto the orbiting laboratory complex.
BEAM was manufactured by Las Vegas-based Bigelow Aerospace under a $17.8 million contract with NASA. It will remain joined to the station for at least a two-year test period.
The 3115 pound (1413 kg) BEAM will test the use of an expandable space habitat in microgravity with humans for the first time.
It was extracted from the Dragon’s trunk overnight with the robotic Canadarm2 and then installed on the aft port of the Tranquility module at 5:36 a.m. EDT over a period of about 4 hours. The station was flying over the Southern Pacific Ocean at the moment of berthing early Saturday.
NASA astronaut and ISS Expedition 47 crew member Tim Kopra snapped a super cool photo of BEAM in transit, shown above.

BEAM was carried to orbit in a compressed form inside the Dragon’s truck following the April 8 blast off from Cape Canaveral Air Force Station at 4:43 p.m. EDT on the Dragon CRS-8 resupply mission for NASA to the ISS.
BEAM is a prototype inflatable habitat that could revolutionize the method of construction of future habitable modules intended for use both in Low Earth Orbit (LEO) as well as for deep space expeditions Beyond Earth Orbit (BEO) to destinations including the Moon, Asteroids and Mars.
The advantage of expandable habitats is that they offer a much better volume to weight ratio compared to standard rigid metallic structures such as all of the current ISS pressurized modules.
It is constructed of lighter weight reinforced fabric rather that metal. This counts as the first test of an expandable module and investigators want to determine how it fares with respect to protection again solar radiation, space debris and the temperature extremes of space.
Furthermore they also take up much less space inside the payload fairing of a rocket during launch.
Watch this animation showing how Canadarm2 transports BEAM from the Dragon spacecraft to a side berthing port on Tranquility where it will soon be expanded.

Current plans call for the module to be expanded in late May with air. It will expand to nearly five times from its compressed size of 8 feet in diameter by 7 feet in length to roughly 10 feet in diameter and 13 feet in length. Once inflated it will provide 565 cubic feet (16 m3) of habitable volume.
Exactly how it will expand is also an experiment and could happen in multiple ways. Therefore the team will exercise great caution and carefully monitor the inflation and check for leaks.

The astronauts will first enter BEAM about a week after the expansion. Thereafter they will visit it about 2 or 3 times per year for several hours to retrieve sensor data and assess conditions, say NASA officials.
Visits could perhaps occur even frequently more if NASA approves. says Bigelow CEO Robert Bigelow.
BEAM is an extraordinary test bed in itself.

But Robert Bigelow hopes that BEAM can be used to conduct science experiments after maybe a six month shakedown cruise, if all goes well, and NASA approves a wider usage.
Bigelow Aerospace has already taken in the next step in expandable habitats.
Earlier this week, Bigelow and rocket builder United Launch Alliance (ULA) announced they are joining forces to develop and launch the B330 expandable commercial habitat module in 2020 on an Atlas V. It is about 20 times larger and far more capable. Details in my story here.
Robert Bigelow says he hopes that NASA will approve docking of the B330 at the ISS.

The SpaceX Dragon spacecraft delivered almost 7,000 pounds of cargo.
CRS-8 counts as the company’s eighth flight to deliver supplies, science experiments and technology demonstrations to the ISS for the crews of Expeditions 47 and 48 to support dozens of the approximately 250 science and research investigations in progress.

SpaceX has released a slew of up close photos showing the sensational “super smooth” touchdown last week of a Falcon 9 booster on a tiny droneship at sea located several hundred miles (km) off the East coast of Florida.
“This time it really went super smooth,” Hans Koenigsmann, SpaceX VP of Flight Reliability, told Universe Today at the NorthEast Astronomy and Space Forum (NEAF) held in Suffern, NY. “The rest is history almost.”
The dramatic propulsive descent and soft landing of the SpaceX Falcon 9 first stage took place last Friday, April 8 about 9 minutes after blasting off from Cape Canaveral Air Force Station at 4:43 p.m. EDT on the Dragon CRS-8 resupply mission for NASA to the International Space Station (ISS).
The breathtaking new photos show the boosters central Merlin 1D engine refiring to propulsively slow the first stage descent with all four landing legs unfurled and locked in place at the bottom and all four grid fins deployed at the top.
Why did it all go so well, comparing this landing to the prior attempts? Basically the return trajectory was less challenging due to the nature of the NASA payload and launch trajectory.
“We were more confident about this droneship landing,” Koenigsmann said at NEAF.
“I knew the trajectory we had [for CRS-8] was more benign, although not super benign. But certainly benigner than for what we had before on the SES-9 mission, the previous one. The [droneship] landing trajectory we had for the previous one on SES-9 was really challenging.”
“This one was relatively benign. It was really maybe as benign as for the Orbcomm launch [in December 2015] where we had the land landing.”

The diminutive ocean landing platform measures only about 170 ft × 300 ft (52 m × 91 m). SpaceX formally dubs it an ‘Autonomous Spaceport Drone Ship’ or ASDS.
The ocean going ship is named “Of Course I Still Love You” after a starship from a novel written by Iain M. Banks.
It was stationed some 200 miles off shore of Cape Canaveral, Florida surrounded by the vastness of the Atlantic Ocean.

“The CRS-8 launch was one of the easiest ones we ever had.”
The revolutionary rocket recovery event counts as the first successful droneship landing of a rocket in history and is paving the way towards eventual rocket recycling aimed at dramatically slashing the cost of access to space.
The final moments of the 15 story tall boosters approach and hover landing was captured up close in stunning high resolution imagery recorded by multiple remote cameras set up right on the ocean going platform by SpaceX photographer Ben Cooper.
Landing the booster on land rather than at sea was actually an option this time around. But SpaceX managers wanted to try and nail a platform at sea landing to learn more and validate their calculations and projections.
“As Elon Musk said at the post-landing press conference of Friday, we could have actually come back to land- to land this one on land,” Koenigsmann elaborated.
“But we decided to land on the drone ship first to make sure that on the droneship we had worked everything out!”
“And that’s exactly what happened. So I felt this was only going out a little bit on the limb,” but not too much.”

Before the CRS-8 launch, Koenigsmann had rated the chances of a successful landing recovery rather high.
Three previous attempts by SpaceX to land on a droneship at sea were partially successful, as the stage made a pinpoint flyback to the tiny droneship, but it either hit too hard or tipped over in the final moments when a landing leg failed to fully deploy or lock in place.
“Everything went perfect with the launch,” Koengismann said. “We just still have to do the post launch data review.”

The primary goal of the Falcon 9 launch on April 8 was carrying the SpaceX Dragon CRS-8 cargo freighter to low Earth orbit on a commercial resupply delivery mission for NASA to the International Space Station (ISS).
Dragon arrived at the station on Sunday, April 10, loaded with 3 tons of supplies, science experiments and the BEAM experimental expandable module.
Landing on the barge was a secondary goal of SpaceX and not part of the primary mission for NASA.

The recovered booster will be cleaned and defueled, says SpaceX spokesman John Taylor.
SpaceX engineers will conduct a series of 12 test firings to ensure all is well operationally and that the booster can be re-launched.
SpaceX hopes to refly the recovered booster in a few months, perhaps as early as this summer.

On April 12th, 1961, the first human being broke free of the gravity bond with Earth, and orbited the planet.
Though most everyone is familiar with the American Apollo astronauts who walked on the Moon, what it took to get there, and the “One small step…” of Neil Armstrong, fewer people are familiar with Yuri Gagarin, the Soviet cosmonaut who was the first human in space. He orbited Earth in his Vostok 1 spacecraft for 108 minutes.
Gagarin became an international celebrity at the time. He received the USSR’s highest honor, the Hero of the Soviet Union. Quite an honor, and quite an achievement for someone who, as a child, survived the Nazi occupation of Russia by living in a tiny mud hut with those members of his family who were not deported for slave labour by the Germans.
The Space Race between the USA and the USSR was in full swing at the time of Gagarin’s flight, and only one month after Gagarin’s historic journey, American astronaut Alan Shepard reached space. But Shepard’s journey was only a 15 minute sub-orbital flight.
Gagarin only has one space flight to his credit, aboard the Vostok 1 in 1961. He did serve as back-up crew for the Soyuz 1 mission though. Gagarin was a test pilot before becoming a cosmonaut, and he died while piloting a Mig-15 fighter jet in 1968.
Space travel in our age is full of ‘firsts.’ It’s the nature of our times. But there can only ever be one first person to leave Earth, and that accomplishment will echo down the ages. Scores of people have been into space now. Their accomplishments are impressive, and they deserve recognition.

All around, today, April 8, was a great day for the future of space exploration. SpaceX successfully restarted their critical cargo flights for NASA to stock the International Space Station (ISS) with essential supplies and groundbreaking science experiments, while the innovative firm also successfully landed the first stage of their Falcon 9 rocket on a barge at sea.
The triumphant ‘Return to Flight’ launch of the upgraded SpaceX Falcon 9 with the Dragon CRS-8 cargo freighter was the primary goal of Friday’s launch and validated the hardware fixes put in place following the catastrophic failure of the previous Dragon CRS-7 cargo ship two minutes after liftoff on June 28, 2015 due to a faulty strut in the boosters second stage.
Landing the booster safely on a drone ship at sea was the secondary goal of the flight but is critical towards achieving the vision of rocket recovery and reusability at the heart of SpaceX Founder Elon Musk’s dream of slashing the cost of access to space and one day establishing a ‘City on Mars.”
The weather was fantastic in the sunshine state as the two stage SpaceX Falcon 9 rocket boasting over 1.3 million pounds of thrust launched on time Friday at 4:43 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

The Dragon spacecraft is delivering almost 7,000 pounds of cargo, including the Bigelow Expandable Activity Module (BEAM), to the orbital laboratory.
Friday’s launch marks the first for a Dragon since the catastrophic failure of the SpaceX Falcon 9 last June.
CRS-8 counts as the company’s eighth flight to deliver supplies, science experiments and technology demonstrations to the ISS for the crews of Expeditions 47 and 48 to support dozens of the approximately 250 science and research investigations in progress.
Packed aboard the Dragon’s unpressurized trunk section is the experimental Bigelow Expandable Activity Module (BEAM) – an experimental expandable capsule that the crew will attach to the space station. The 3115 pound (1413 kg) BEAM will test the use of an expandable space habitat in microgravity. BEAM will expand to roughly 13-feet-long and 10.5 feet in diameter after it is installed.
Among the new experiments arriving to the station will be Veggie-3 to grow Chinese lettuce in microgravity as a followup to Zinnias recently grown, an investigation to study muscle atrophy and bone loss in space, using microgravity to seek insight into the interactions of particle flows at the nanoscale level and use protein crystal growth in microgravity to help in the design of new drugs to fight disease, as well as reflight of 25 student experiments from Student Spaceflight Experiments Program (SSEP) Odyssey II payload that were lost during the CRS-7 launch failure.
“The cargo will allow investigators to use microgravity conditions to test the viability of expandable space habitats, assess the impact of antibodies on muscle wasting, use protein crystal growth to aid the design of new disease-fighting drugs and investigate how microbes could affect the health of the crew and their equipment over a long duration mission,” said NASA Deputy Administrator Dava Newman.

Dragon reached its preliminary orbit about 10 minutes after launch and deployed its solar arrays as targeted and as seen on the live webcast. It now begins a carefully choreographed series of thruster firings to reach the space station.
After a 2 day orbital chase Dragon is set to arrive at the orbiting outpost on Sunday, April 10.
NASA astronaut Jeff Williams and ESA (European Space Agency) astronaut Tim Peake will then reach out with the station’s Canadian-built robotic arm to grapple and capture the Dragon spacecraft.
Ground commands will be sent from Houston to the station’s arm to install Dragon on the Earth-facing bottom side of the Harmony module for its stay at the space station. Live coverage of the rendezvous and capture will begin at 5:30 a.m. on NASA TV, with installation set to begin at 9:30 a.m.
In a historic first, the launch of a SpaceX Dragon cargo spacecraft sets the stage for the first time that two American cargo ships will be simultaneously attached to the ISS. The Orbital ATK Cygnus cargo freighter launched just launched on March 22 and arrived on March 26 at a neighboring docking port on the Unity module.
Dragon will remain at the station until it returns for Earth on May 11 for a parachute assisted splash down in the Pacific Ocean off the west coast of Baja California. It will be packed with almost 3,500 pounds off cargo and numerous science samples, including those biological samples collected by 1 year ISS crew member Scott Kelly, for return to investigators, hardware and spacewalking tools, some additional broken hardware for repair and some items of trash for disposal.

It’s time to whip out your 3-D glasses to enjoy and scrutinize the remarkable detail of spectacular terrain revealed in a new high resolution stereo image of Pluto – King of the Kuiper Belt! – taken by NASA’s New Horizons spacecraft.
The amazing new stereo Plutonian image focuses on an area dominated by a mysterious feature that geologists call ‘bladed’ terrain – seen above – and its unlike anything seen elsewhere in our solar system.
Its located in a broad region of rough highlands informally known as Tartarus Dorsa – situated to the east of the Pluto’s huge heart shaped feature called Tombaugh Regio. The best resolution is approximately 1,000 feet (310 meters).
The stereo view combines a pair of images captured by New Horizons Ralph/Multispectral Visible Imaging Camera (MVIC) science instruments. They were taken about 14 minutes apart on during history making first ever flyby of the Pluto planetary system on July 14, 2015.
The first was taken when New Horizons was 16,000 miles (25,000 kilometers) away from Pluto, the second when the spacecraft was 10,000 miles (about 17,000 kilometers) away.
The blades align from north to south, typically reach up to about 550 yards (500 meters) high and are spaced about 2-4 miles (3-5 kilometers). Thus they are among the planets steepest features. They are “perched on a much broader set of rounded ridges that are separated by flat valley floors,” according to descriptions from the New Horizons science team.
This color image of Pluto taken by NASA’s New Horizons spacecraft shows rounded and bizarrely textured mountains, informally named the Tartarus Dorsa, rise up along Pluto’s terminator and show intricate but puzzling patterns of blue-gray ridges and reddish material in between. This view, roughly 330 miles (530 kilometers) across, combines blue, red and infrared images taken by the Ralph/Multispectral Visual Imaging Camera (MVIC) on July 14, 2015, and resolves details and colors on scales as small as 0.8 miles (1.3 kilometers).

Mission scientists have also noted that the bladed terrain has the texture of “snakeskin” owing to their “scaly raised relief.”
In the companion global image from NASA (below), the bladed terrain is outlined in red and shown to extend quite far to the east of Tombaugh Regio.
The composite image was taken on July 13, 2015, the day before the closest approach flyby, when the probe was farther away thus shows lower resolution. It combines a pair of images from two of the science instruments – a Ralph/Multispectral Visible Imaging Camera (MVIC) color scan and an image from the Long Range Reconnaissance Imager (LORRI).

The MVIC scan was taken from a range of 1 million miles (1.6 million kilometers), at a resolution of 20 miles (32 kilometers) per pixel. The corresponding LORRI image was obtained from roughly the same range, but has a higher spatial resolution of 5 miles (8 kilometers) per pixel, say officials.
Scientists have developed several possible theories about the origins of the bladed terrain, including erosion from evaporating ices or deposition of methane ices.
Measurements from the Linear Etalon Imaging Spectral Array (LEISA) instrument reveal that that this region “is composed of methane (CH4) ice with a smattering of water,” reports New Horizons researcher Orkan Umurhan.
He speculates that “the material making up the bladed terrain is a methane clathrate. A clathrate is a structure in which a primary molecular species (say water, or H2O) forms a crystalline ‘cage’ to contain a guest molecule (methane or CH4, for example).”
But the question of whether that methane ice is strong enough to maintain the steep walled snakeskin features, will take much more research to determine a conclusive answer.
Umurhan suggests that more research could help determine if the “methane clathrates in the icy moons of the outer solar system and also in the Kuiper Belt were formed way back before the solar system formed – i.e., within the protosolar nebula – potentially making them probably some of the oldest materials in our solar system.”
Pluto continues to amaze and surprise us as the data streams back to eagerly waiting scientists on Earth over many more months to come – followed by years and decades of painstaking analysis.
This new global mosaic view of Pluto was created from the latest high-resolution images to be downlinked from NASA’s New Horizons spacecraft and released on Sept. 11, 2015. The images were taken as New Horizons flew past Pluto on July 14, 2015, from a distance of 50,000 miles (80,000 kilometers). This new mosaic was stitched from over two dozen raw images captured by the LORRI imager and colorized. Annotated with informal place names.

During New Horizons flyby on July 14, 2015, it discovered that Pluto is the biggest object in the outer solar system and thus the ‘King of the Kuiper Belt.”
The Kuiper Belt comprises the third and outermost region of worlds in our solar system.
Pluto is the last planet in our solar system to be visited in the initial reconnaissance of planets by spacecraft from Earth since the dawn of the Space Age.
New Horizons remains on target to fly by a second Kuiper Belt Object (KBO) on Jan. 1, 2019 – tentatively named PT1, for Potential Target 1. It is much smaller than Pluto and was recently selected based on images taken by NASA’s Hubble Space Telescope.
