KENNEDY SPACE CENTER, FL – A triad of August liftoffs from the Florida Space Coast inaugurates Monday, Aug. 14 with a science laden commercial SpaceX Dragon bound for the International Space Station (ISS) – loaded with over 3 tons of NASA science, hardware and supplies including a cosmic ray detector, medical research experiments dealing with Parkinson’s disease and lung tissue, vegetable seeds, mice and much more, following a successful engine test firing of the Falcon 9 booster on Thursday.

“Static fire test of Falcon 9 complete,” SpaceX confirmed via Twitter soon after completion of the test at 9:10 a.m. EDT, Aug 10. (1310 GMT) “—targeting August 14 launch from Pad 39A for Dragon’s next resupply mission to the @Space_Station.”

Check out our photos & videos herein of the Aug. 10 static first test of the Falcon 9 first stage that paves the path to blastoff – as witnessed live by Ken Kremer and Jeff Seibert.

The triple headed sunshine state space spectacular kicks off with Monday’s lunchtime launch of the next unmanned SpaceX Dragon cargo freighter to the ISS from seaside pad 39A at NASA’s Kennedy Space Center in Florida, now targeted for Aug. 14 at 12:31 p.m. EDT (1631 GMT).

The closely spaced trio of space launches marches forward barely 4 days later with liftoff of NASA’s amazingly insectoid-looking TDRS-M science relay comsat slated for Friday morning Aug. 18 atop a United Launch Alliance (ULA) Atlas V rocket.

Lastly, a week after TDRS-M and just 11 days after the SpaceX Dragon an Orbital ATK Minotaur 4 rocket is due to blastoff just before midnight Aug. 25 and carry the ORS 5 mission to orbit for the U.S. military’s Operationally Responsive Space program. The Minotaur IV utilizes three stages from decommissioned Peacekeeper ICBMs formerly aimed at the Russians.

Of course getting 3 rockets off the ground from 3 different companies is all highly dependent on Florida’s hugely fickle hurricane season weather and the ever present reality of potential technical glitches, errant boaters and more – possibly resulting in a domino effect of cascading launch scrubs.

And sandwiched in between the Florida Space Coast blastoffs is the Total Solar ‘Eclipse Across America’ on Monday, Aug. 21 – for the first time in 99 years!

Although KSC and central Florida are not within the path of totality, the sun will still be about 85% obscured by the Moon.

So if you’re looking for bang for the space buck, the next two weeks have a lot to offer space and astronomy enthusiasts.

The 20-foot high, 12-foot-diameter Dragon CRS-12 vessel is carrying more than 6,400 pounds ( 2,900 kg) of science experiments and research instruments, crew supplies, food water, clothing, hardware, gear and spare parts to the million pound orbiting laboratory complex. 20 mice are also onboard. This will support dozens of the 250 research investigations and experiments being conducted by Expedition 52 and 53 crew members.

If you can’t personally be here to witness the launch in Florida, you can always watch NASA’s live coverage on NASA Television and the agency’s website.

The SpaceX/Dragon CRS-12 launch coverage will be broadcast on NASA TV beginning noon on Aug. 14 with additional commentary on the NASA launch blog.

SpaceX will also offer their own live webcast beginning approximately 15 minutes before launch at about 12:16 p.m. EDT.

You can watch the launch live at NASA TV at – http://www.nasa.gov/nasatv

You can also watch the launch live at SpaceX hosted Webcast at – spacex.com/webcast

In the event of delay for any reason, the next launch opportunity is Tuesday, Aug. 15 with NASA TV coverage starting about 11:30 a.m. EDT.

The weather looks decent at this time with a 70% chance of favorable conditions at launch time according to U.S. Air Force meteorologists with the 45th Space Wing Weather Squadron at Patrick Air Force Base. The primary concerns on Aug. 14 are cumulus clouds and the potential for precipitation in the flight path.

The odds remain at 70% favorable for the 24 hour scrub turnaround day on Aug. 15.

Everything is currently on track for Monday’s noontime launch of the 230 foot tall SpaceX Falcon 9 on the NASA contracted SpaceX CRS-12 resupply mission to the million pound orbiting lab complex.

However since the launch window is instantaneous there is no margin for error. In case any delays arise during the countdown due to technical or weather issues a 24 hour scrub to Tuesday will result.

The lunchtime launch coincidently offers a convenient and spectacular opportunity for fun for the whole family as space enthusiasts flock in from around the globe.

Plus SpaceX will attempt a land landing of the 156 foot tall first stage back at the Cape at Landing Zone 1 some 8 minutes after liftoff – thus a double whammy of space action !!– punctuated by multiple loud sonic booms at booster landing time that will figuratively knock your socks off.

To date SpaceX has successfully recovered 13 boosters; 5 by land and 8 by sea, over the past 18 months. It’s a feat straight out of science fiction but aimed at drastically slashing the high cost of access to space.

The recent BulgariaSat-1 and Iridium-2 missions counted as the eighth and ninth SpaceX launches of 2017.

CRS-12 marks the eleventh SpaceX launch of 2017 and will establish a new single year record.

In contrast to the prior CRS-11 mission which flew a recycled Dragon, the CRS-12 Dragon is newly built.

The CRS-12 Dragon will be the last newly built one, says NASA. The remaining SpaceX CRS mission will utilize reused spaceships.

The Falcon 9 is also new and will attempt a land landing back at the Cape at Landing Zone-1 (LZ-1).

If the Aug. 14 launch occurs as scheduled, the Dragon will reach its preliminary orbit about 10 minutes later and deploy its life giving solar arrays. Dragon then begins a 2 day orbital chase of the station via a carefully choreographed series of thruster firings that bring the commercial spacecraft to rendezvous with the space station on Aug. 16.

Dragon will be grappled with the station’s Canadian built robotic arm at approximately 7 a.m. EDT on Aug. 16 by astronauts Jack Fischer of NASA and Paolo Nespoli of ESA (European Space Agency). It then will be installed on the Harmony module.

The Dragon spacecraft will spend approximately one month attached to the space station, returning to Earth in mid-September with results of earlier experiments.

Dragon CRS-12 is SpaceX’s third contracted resupply mission to launch this year for NASA.

The prior SpaceX cargo ships launched on Feb 19 and June 3, 2017 on the CRS-10 and CRS-11 missions to the space station. CRS-10 is further noteworthy as being the first SpaceX launch of a Falcon 9 from NASA’s historic pad 39A.

SpaceX leased pad 39A from NASA in 2014 and after refurbishments placed the pad back in service this year for the first time since the retirement of the space shuttles in 2011.

Previous launches include 11 Apollo flights, the launch of the unmanned Skylab in 1973, 82 shuttle flights and five SpaceX launches.

Cargo Manifest for CRS-12:

TOTAL CARGO: 6415.4 lbs. / 2910 kg

TOTAL PRESSURIZED CARGO WITH PACKAGING: 3642 lbs. / 1652 kg
• Science Investigations 2019.4 lbs. / 916 kg
• Crew Supplies 485 lbs. / 220 kg
• Vehicle Hardware 747.4 lbs. / 339 kg
• Spacewalk Equipment 66.1 lbs. / 30 kg
• Computer Resources 116.8 lbs. / 53 kg

UNPRESSURIZED 2773.4 lbs. / 1258 kg
• Cosmic-Ray Energetics and Mass (CREAM) 2773.4 lbs. / 1258 kg

The CREAM instrument from the University of Maryland will be stowed for launch inside the Dragon’s unpressurized trunk. Astronauts will use the stations robotic arm to pluck it from the trunk and attach it to the exposed porch of the Japanese Experiment Module (JEM).

Here is a NASA description of CREAM:

The Cosmic Ray Energetics and Mass (CREAM) instrument, attached to the Japanese Experiment Module Exposed Facility, measures the charges of cosmic rays ranging from hydrogen to iron nuclei. The data collected from the CREAM instrument will be used to address fundamental science questions on the origins and history of cosmic rays. CREAM’s three-year mission will help the scientific community build a stronger understanding of the fundamental structure of the universe.

The LRRK2 experiment seeks to grow larger crystals of the protein to investigate Parkinson’s disease and help develop new therapies:

Here is a NASA description of LRRK2:

Crystallization of Leucine-rich repeat kinase 2 (LRRK2) under Microgravity Conditions (CASIS PCG 7) will use the orbiting laboratory’s microgravity environment to grow larger versions of this important protein, implicated in Parkinson’s disease. Developed by the Michael J. Fox Foundation, Anatrace and Com-Pac International, researchers will look to take advantage of the station’s microgravity environment which allows protein crystals to grow larger and in more perfect shapes than earth-grown crystals, allowing them to be better analyzed on Earth. Defining the exact shape and morphology of LRRK2 would help scientists to better understand the pathology of Parkinson’s and aid in the development of therapies against this target.

Watch this Michael J. Fox video describing the LRRK2 crystallization experiment:

Star Ark: A Living, Self-Sustaining Spaceship

Think of the ease. With a simple command of “Make it so” humans travelled from one star to the next in less time than for drinking a cup of coffee. At least that’s what happens in the time-restricted domain of television. In reality it’s not so easy. Nor does Rachel Armstrong misrepresent this point in her book of essays within “Star Ark – A Living Self-Sustaining Spaceship“; a book that brings some fundamental reality to star travel.

Yes, many people want to travel to other stars. We’re not ready for that. We’re still just planning on getting outside Earth’s protective atmosphere (again). Yet making preparations and doing judicious planning is the aim of this book. Wisely though, this book isn’t technical. It has no mention of specific impulse calculations or ion shields. Rather, this book takes a very liberal view of space travel and ponders deep questions such as whether the cosmos is an ecosystem.

Does our species have an appropriate culture for space travel? What exactly is a human? These concerns get raised in some very thought provoking sections. And given that the editor is an architect and one who apparently considers the emotional qualities of a structure as much as functional qualities, then this book’s presentation tends to be a little more on the philosophical side of things.

In particular, it looks at the benefits of living entities. For instance it notes that humans live in symbiotic relationships with a host of internal and external organisms. Most have already gone into space either within people who have traveled in space or possibly upon probes sent to other planets. So we aren’t the only species that’s traveled beyond Earth. But which beings are sufficient and necessary to keep humans alive for the generations needed to travel to another star? That question and many answers come up often.

As well, the essays get into bigger questions such as: What is life? Could the vessel be an organic construct? How might today’s humans evolve to tomorrow’s star travelers? Should humans travel in space and promote/continue panspermia? Yes, these questions and many more are raised in the essays collected within this book. And true to form for any book considering star travel, there aren’t any strict answers. There are however lots of ideas and concepts to better prepare humans.

Much of this book seems to center around the authors’ involvement with the Persephone project of Icarus Interstellar. Yet there’s very little description of either. However, the book does have wonderful descriptions of Biitschli experiments, explanations of living walls and critiques of theatrical productions.

There are a few fictional passages and some poetry. The long list of references indicates a broad knowledge of the technical issues, though the focus is on humanity and the living aspect. This focus flows through the essays, but having a collection of many authors makes for a disjointed flow. The writing styles are unique, the viewpoints are particular and the emphasis specialized for each. One common viewpoint does keep arising though. That is, we are already on a living spaceship; the Earth. Earth gives a unique platform for assessing the ability to travel to other stars. The essays state that it is or at least was a veritable, closed self-sustaining life support system. And, as seems to be the norm these days, the essays acknowledge that solutions for space travel would be just as good for people remaining behind upon Earth or travelling to the Moon or to Mars and so on. This care and concern for living organism keeps the book grounded, so to speak.

The all-encompassing-solution-finder may be a strength or a weakness to Rachel Armstrong’s collection within the book “Star Ark – A Living Self-Sustaining Spaceship”. As the book’s essays describe, humans have an incredible ability to think and act in abstract fashion. Just envisioning an attempt to send sentient beings to another star demonstrates this. But will we be able to enact this idea and what form might a star vessel take? Reading of this is easy. Will taking the necessary steps be just as easy?

The book is available here through Springer.

Sunshield Layers Installed on NASA’s James Webb Space Telescope as Mirror Cryo Cooling Testing Commences

The complex multilayered sunshield that will protect the delicate optics and state of the art infrared science instruments of NASA’s James Webb Space Telescope (JWST) is now fully installed on the spacecraft bus in California, completing another major milestone on the path to launch, NASA announced.

Meanwhile a critical cryogenic cooling test of Webb’s mirrors and science instrument bus has commenced inside a giant chamber at NASA’s Johnson Space Center in Texas, marking another major milestone as the mammoth telescope comes together after years of development.

NASA’s $8.8 Billion James Webb Space Telescope is the most powerful space telescope ever built and is the scientific successor to the phenomenally successful Hubble Space Telescope (HST).

The Webb telescopes groundbreaking tennis court sized sunshield subsystem consists of five layers of kapton that will keep the optics and instruments incredibly cool, by reducing the incoming sunside facing temperature more than 570 degrees Fahrenheit. Each layer is as thin as a human hair.

“The sunshield layers work together to reduce the temperatures between the hot and cold sides of the observatory by approximately 570 degrees Fahrenheit,” according to NASA. “Each successive layer of the sunshield is cooler than the one below.”

The painstaking work to integrate the five sunshield membranes was carried out in June and July by engineers and technicians working at the Northrop Grumman Corporation facility in Redondo Beach, California.

“All five sunshield membranes have been installed and will be folded over the next few weeks,” said Paul Geithner, deputy project manager – technical for the Webb telescope at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement.

Deployment tests of the folded sunshield start in August.

Webb’s four research instruments cannot function without the essential cooling provided by the sunshield deployment.

“This is a huge milestone for the Webb telescope as we prepare for launch,” said Jim Flynn, Webb sunshield manager, Northrop Grumman Aerospace Systems.

“The groundbreaking tennis court sized sunshield will shield the optics from heat and assist in providing the imaging of the formation of stars and galaxies more than 13.5 billion years ago.”

Webb is designed to look at the first light of the Universe and will be able to peer back in time to when the first stars and first galaxies were forming. It will also study the history of our universe and the formation of our solar system as well as other solar systems and exoplanets, some of which may be capable of supporting life on planets similar to Earth.

After successfully passing a rigorous series of vibration and acoustic environmental tests earlier this year at NASA Goddard in March, the mirror and instrument assembly was shipped to NASA Johnson in May for the cryo cooling tests.

“Those tests ensured Webb can withstand the vibration and noise created during the telescope’s launch into space. Currently, engineers are analyzing this data to prepare for a final round of vibration and acoustic testing, once Webb is joined with the spacecraft bus and sunshield next year,” says NASA.

The cryogenic cooling test will last 100 days and is being carried out inside the giant thermal vacuum known as Chamber A at the Johnson Space Center in Houston.

“A combination of liquid nitrogen and cold gaseous helium will be used to cool the telescope and science instruments to their operational temperature during high-vacuum operations,” said Mark Voyton, manager of testing effort, who works at the NASA Goddard Space Flight Center in Greenbelt, Maryland.

Next year, the tennis-court sized sunshield and spacecraft bus will be combined to make up the entire observatory.

The Webb Telescope is a joint international collaborative project between NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA).

Assembly of the Webb telescope is currently on target and slated to launch on an ESA Ariane V booster from the Guiana Space Center in Kourou, French Guiana in October 2018.

NASA and ESA are currently evaluating a potential launch scheduling conflict with ESA’s BepiColombo mission to Mercury.

Musk Says Maiden Falcon Heavy to Launch in November, Acknowledges High Risk and Releases New Animation

Before the year is out, the long awaited debut launch of the triple barreled Falcon Heavy rocket may at last be in sight says SpaceX CEO and founder Elon Musk, as he forthrightly acknowledges it comes with high risk and released a stunning launch and landing animation earlier today, Aug. 4.

After years of painstaking development and delays, the inaugural blastoff of the SpaceX Falcon Heavy is currently slated for November 2017 from NASA’s Kennedy Space Center in Florida, according to Musk.

“Falcon Heavy maiden launch this November,” SpaceX CEO and billionaire founder Elon Musk tweeted last week.

“Lot that can go wrong in the November launch …,” Musk said today on Instagram, downplaying the chances of complete success.

And to whet the appetites of space enthusiasts worldwide, just today Musk also published a one minute long draft animation illustrating the Falcon Heavy triple booster launch and how the individual landings of the trio of first stage booster cores will take place – nearly simultaneously.

https://www.instagram.com/p/BXXiVWFgphb/

“Side booster rockets return to Cape Canaveral,” explains Musk on twitter. “Center lands on droneship.”

The two side boosters will be recycled from prior Falcon 9 launches and make precision guided propulsive, upright ground soft landings back at Cape Canaveral Air Force Station, Florida. Each booster is outfitted with a quartet of grid fins and landing legs. The center core is newly built and heavily modified.

“Sides run high thrust, center is lower thrust until sides separate & fly back. Center then throttles up, keeps burning & lands on droneship. If we’re lucky!” Musk elaborated.

The center booster will touch down on an ocean going droneship prepositioned in the Atlantic Ocean some 400 miles (600 km) off of Florida’s east coast.

To date SpaceX first stages from KSC launches have touched down either on land at Landing Zone-1 (LZ-1) at the Cape or at sea on the “Of Course I Still Love You” droneship barge (OCISLY).

The launch of the extremely complicated Falcon Heavy booster with 27 first stage Merlin 1D engines also comes associated with a huge risk – and he hopes that it at least rises far enough off the ground to minimize the chances of damage to the historic pad 39A at the Kennedy Space Center.

“There’s a lot of risk associated with Falcon Heavy, a real good chance that that vehicle does not make it to orbit,” Musk said recently while speaking at the International Space Station Research and Development Conference in Washington, D.C. on July 19.

“I want to make sure to set expectations accordingly. I hope it makes it far enough beyond the pad so that it does not cause pad damage. I would consider even that a win, to be honest.”

Musk originally proposed the Falcon Heavy in 2011 and targeted a maiden mission in 2013.

Whenever it does launch, the Falcon Heavy will become the world’s most powerful rocket.

“I think Falcon Heavy is going to be a great vehicle,” Musk stated. “There’s just so much that’s really impossible to test on the ground, and we’ll do our best.

“Falcon Heavy requires the simultaneous ignition of 27 orbit-class engines. There’s a lot that can go wrong there.”

Designing and building Falcon Heavy has proven to be far more difficult than Musk ever imagined, and the center booster had to be significantly redesigned.

“It actually ended up being way harder to do Falcon Heavy than we thought,” Musk explained.

“At first it sounds real easy! You just stick two first stages on as strap-on boosters. How hard can that be?” But then everything changes. All the loads change, aerodynamics totally change. You’ve tripled the vibration and acoustics. You sort of break the qualification levels on so much of the hardware.”

“The amount of load you’re putting through that center core is crazy because you’ve got two super-powerful boosters also shoving that center core. So we had to redesign the whole center core airframe,” Musk added. “It’s not like the Falcon 9 – because it’s got to take so much load. Then you’ve got separation systems.”

Due to the high risk, there will be no payload from a paying customer housed inside the nose cone atop the center core. Only a dummy payload will be installed on the maiden mission.

However future Falcon Heavy missions have been manifested with commercial and science payloads.

Musk also hopes to launch a pair of paying private astronauts on a trip around the Moon and back as soon as 2018 while journeying inside a Crew Dragon spacecraft with the Falcon Heavy – similar to what his company is developing for NASA for commercial ferry missions to low Earth orbit (LEO) and the International Space Station (ISS).

Falcon Heavy will blast off with about twice the thrust of the Delta IV Heavy, currently the worlds most powerful rocket. The United Launch Alliance (ULA) Delta IV Heavy (D4H) has been the world’s mightiest rocket since the retirement of NASA’s Space Shuttles in 2011.

The Falcon Heavy sports about 2/3 the liftoff thrust of NASA’s Saturn V manned moon landing rockets – last launched in the 1970s.

The Falcon Heavy is comprised of three Falcon 9 cores. The Delta IV Heavy is comprised of three Delta Common Core Boosters.

The combined trio of Falcon 9 cores will generate about 5.1 million pounds of liftoff thrust upon ignition from Launch Complex 39A at the Kennedy Space Center in Florida.

“With the ability to lift into orbit over 54 metric tons (119,000 lb)–a mass equivalent to a 737 jetliner loaded with passengers, crew, luggage and fuel–Falcon Heavy can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy, at one-third the cost,” according to the SpaceX website.

“The nice thing is when you fully optimize it, it’s about two-and-a-half times the payload capability of a Falcon 9,” Musk notes. “It’s well over 100,000 pounds to LEO of payload capability, 50 tons. It can even get up a little higher than that if optimized.”

The two stage Falcon Heavy stands more than 229.6 feet (70 meters) tall and is 39.9 feet wide (12.2 meters).

It weighs more than 3.1 million pounds (1.4 million kilograms).

Like the Falcon 9 it will be fueled with liquid oxygen and RP-1 kerosene propellants.

The thunder, power and roar of over 5 million pounds of liftoff thrust from the Falcon Heavy’s 27 engines is absolutely certain to be a thrilling, earth-shaking space spectacular !! Thus placing it in a class of its own unlike any US launch since NASA’s Saturn V and Space Shuttles rocketed to the high frontier from the same pad.

“I encourage people to come down to the Cape to see the first Falcon Heavy mission,” Musk said. “It’s guaranteed to be exciting.”

But before the Falcon Heavy can actually be rolled up to launch position at pad 39A, SpaceX must first complete repairs and refurbishment to nearby pad 40.

That Cape pad was heavily damaged nearly a year ago during a catastrophic launch pad explosion that took place in Sept. 2016 during a routine prelaunch fueling and static fire engine test of a Falcon 9 rocket with the Amos-6 commercial comsat payload bolted on top.

Pad 40 must achieve operational launch status again before SpaceX can commit to the Falcon Heavy launches at Pad 39A. Workers will also need to finish construction work at pad 39A to support the Heavy launches.

To date SpaceX has successfully demonstrated the recovery of thirteen boosters by land and sea.

Furthermore SpaceX engineers have advanced to the next step and successfully recycled, reflown and relaunched two ‘flight-proven first stages this year in March and June of 2017 from the Kennedy Space Center in Florida involving the SES-10 and BulgariaSat-1 launches respectively.

NASA Voyager Probes Still Going Strong After 40 Years

Earth's Greatest Hits: the Golden Record attached to the Voyager 1 and 2 spacecraft. Credit: NASA/JPL.

Forty years ago, the Voyager 1 and 2 missions began their journey from Earth to become the farthest-reaching missions in history. In the course of their missions, the two probes spent the next two decades sailing past the gas giants of Jupiter and Saturn. And while Voyager 1 then ventured into the outer Solar System, Voyager 2 swung by Uranus and Neptune, becoming the first and only probe in history to explore these worlds.

This summer, the probes will be marking the fortieth anniversary of their launch – on September 5th and August 20th, respectively. Despite having traveled for so long and reaching such considerable distances from Earth, the probes are still in contact with NASA and sending back valuable data. So in addition to being the most distant missions from Earth, they are the longest-running mission in history.

In addition to their distance and longevity, the Voyager spacecraft have also set numerous other records for robotic space missions. For example, in 2012, the Voyager 1 probe became the first and only spacecraft to have entered interstellar space. Voyage 2, meanwhile, is the only probe that has explored all four of the Solar System’s gas/ice giants – Jupiter, Saturn, Uranus and Neptune.

Their discoveries also include the first active volcanoes beyond Earth – on Jupiter’s moon Io – the first evidence of a possible subsurface ocean on Europa, the dense atmosphere around Titan (the only body beyond Earth with a dense, nitrogen-rich atmosphere), the craggy surface of Uranus’ “Frankenstein Moon” Miranda, and the ice plume geysers of Neptune’s largest moon, Triton.

These accomplishments have had immeasurable benefits for planetary science, astronomy and space exploration. They’ve also paved the way for future missions, such as the Galileo and Juno probes, the Cassini-Huygens mission, and the New Horizons spacecraft. As Thomas Zurbuchen, the associate administrator for NASA’s Science Mission Directorate (SMD), said in a recent press statement:

“I believe that few missions can ever match the achievements of the Voyager spacecraft during their four decades of exploration. They have educated us to the unknown wonders of the universe and truly inspired humanity to continue to explore our solar system and beyond.”

But what is perhaps most memorable about the Voyager missions is the special cargo they carry. Each spacecraft carries what is known as the Golden Record, a collection of sounds, pictures and messages that tell of Earth, human history and culture. These records were intended to serve as a sort of time capsule and/or message to any civilizations that retrieved them, should they ever be recovered.

As noted, both ships are still in contact with NASA and sending back mission data. The Voyager 1 probe, as of the writing of this article, is about 20.9 billion km (13 billion mi; 140 AU) from Earth. As it travels northward out of the plane of the planets and into interstellar space, the probe continues to send back information about cosmic rays – which are about four times as abundant in interstellar space than around Earth.

From this, researchers have learned that the heliosphere – the region that contains the Solar System’s planets and solar wind – acts as a sort of radiation shield. Much in the say that Earth’s magnetic field protects us from solar wind (which would otherwise strip away our atmosphere), the heliopause protects the Solar planets from atomic nuclei that travel at close to the speed of light.

Voyager 2, meanwhile, is currently about 17.7 billion km (11 billion mi; 114.3 AU) from Earth. It is traveling south out of the plane of the planets, and is expected to enter interstellar space in a few years. And much like Voyager 1, it is also studying how the heliosphere interacts with the surroundings interstellar medium, using a suite of instruments that measure charged particles, magnetic fields, radio waves and solar wind plasma.

Once Voyager 2 crosses into interstellar space, both probes will be able to sample the medium from two different locations simultaneously. This is expected to tell us much about the magnetic environment that encapsulates our system, and will perhaps teach us more about the history and formation of the Solar System. On top of that, it will let us know what kinds of hazards a possible interstellar mission will have to contend with.

The fact that the two probes are still active after all this time is nothing short of amazing. As Edward Stone – the David Morrisroe Professor of Physics at Caltech, the former VP and Director of NASA’s Jet Propulsion Laboratory, and the Voyager project scientist – said:

“None of us knew, when we launched 40 years ago, that anything would still be working, and continuing on this pioneering journey. The most exciting thing they find in the next five years is likely to be something that we didn’t know was out there to be discovered.”

Keeping the probes going has also been a challenge since the amount of power they generate decreases at a rate of about four watts per year. This has required that engineers learn how to operate the twin spacecraft with ever-decreasing amounts of power, which has forced them to consult documents that are decades old in order to understand the probes’ software and command functions.

Luckily, it has also given former NASA engineers who worked on the Voyager probes the opportunity to offer their experience and expertise. At present, the team that is operating the spacecraft estimate that the probes will run out of power by 2030. However, they will continue to drift along their trajectories long after they do so, traveling at a speed of 48,280 km per hour (30,000 mph) and covering a single AU every 126 days.

*The Voyager 1 spacecraft has started to transverse what JPL has dubbed as a “cosmic purgatory” between our solar system – and interstellar space. Credit: NASA/JPL*

At this rate, they will be within spitting distance of the nearest star in about 40,000 years, and will have completed an orbit of the Milky Way within 225 million years. So its entirely possible that someday, the Golden Records will find their way to a species capable of understanding what they represent. Then again, they might find their way back to Earth someday, informing our distant, distant relatives about life in the 20th century.

And if the craft avoid any catastrophic collisions and can survive in the interstellar medium of space, it is likely that they will continue to be emissaries for humanity long after humanity is dead. It’s good to leave something behind!

Veteran Multinational Trio Launches on Soyuz and Arrives at International Space Station

The Soyuz MS-05 rocket is launched with Expedition 52 flight engineer Sergei Ryazanskiy of Roscosmos, flight engineer Randy Bresnik of NASA, and flight engineer Paolo Nespoli of ESA (European Space Agency), Friday, July 28, 2017 at the Baikonur Cosmodrome in Kazakhstan.

An all veteran multinational trio of astronauts and cosmonauts rocketed to orbit aboard a Russian Soyuz capsule and safely arrived at the International Space Station (ISS) after a fast track rendezvous on Friday, July 28.

NASA astronaut Randy Bresnik, Sergey Ryazanskiy of Roscosmos and Paolo Nespoli of ESA (European Space Agency) docked at the orbiting outpost at 5:54 p.m. EDT (2154 GMT) Friday just six hours after departing our Home Planet.

The three crewmates launched aboard the Russian Soyuz MS-05 spacecraft from the Baikonur Cosmodrome in Kazakhstan during a typically hot mid-summers night at 9:41 p.m. Baikonur time, or 11:41 a.m. EDT, 1541 GMT, as the booster and Baikonur moved into the plane of the space station’s orbit. They blasted to space from the same pad as Yuri Gagarin, the first man in space.

The entire launch sequence aboard the Soyuz rocket performed flawlessly and delivered the Soyuz capsule to its targeted preliminary orbit flowing by the planned opening of the vehicles solar arrays and antennas.

Following a rapid series of orbit raising maneuvers, the Soyuz reached the ISS after 4 orbits and six hours to successfully complete all the rendezvous and docking procedures.

The Soyuz docked at the Earth-facing Russian Rassvet module as the spaceships were flying some 250 mi (400 km) over Germany.

Following the standard pressurization and leak checks, the hatches between the spacecraft and station were opened from inside the ISS at about 9:45 p.m. EDT.

The new trio of Bresnik, Ryazanskiy and Nespoli then floated one by one from the Soyuz into the station and restored the outpost to a full strength crew of six humans.

The veteran space flyers join Commander Fyodor Yurchikhin of Roscosmos and Flight Engineers Peggy Whitson and Jack Fischer of NASA who are already serving aboard.

Thus begins Expedition 52 aboard the million pound orbiting science complex.

This is the second space flight for both Bresnik and Ryazanskiy and the third for Nespoli.

Bresnik previously flew to the space station as a member of the STS-129 space shuttle Atlantis mission in November 2009. The 10 day mission delivered two Express Logistics Carriers (ELC racks) to the space station as part of approximately 30,000 pounds of replacement parts.

Bresnik performed two spacewalks for a total of 11 hours and 50 minutes during the STS-129 mission. He is slated to take command of the ISS as a member of Expedition 53.

The new Expedition 52 crew will spend a four and a half month stint aboard the station and continue over 250 ongoing science investigations in fields such as biology, Earth science, human research, physical sciences and technology development.

Bresnik, Ryazanskiy and Nespoli are slated to stay aboard until returning to Earth in December.

Whitson, Fischer and Yurchikhin are in the home stretch of their mission and will retun to Earth in September. Shortly after their departure, NASA astronauts Mark Vande Hei and Joseph Acaba and Russian cosmonaut Alexander Misurkin will launch on the next Soyuz from Kazakhstan to join the Expedition 53 crew.

Whitson is the most experienced US astronaut with time in space. Her record setting cumulative time in space will exceed 600 days and include a 9 month stay on this flight upon her return to Earth.

She most recently launched to the ISS last year on Nov 17, 2016 aboard a Russian Soyuz capsule from the Baikonur Cosmodrome. This is her 3rd long duration stay aboard the station.

Whitson also holds the record for most spacewalks by a female astronaut. Altogether she has accumulated 53 hours and 23 minutes of EVA time over eight spacewalks.

The newly-expanded Expedition 52 crew expect to welcome a pair of unmanned US cargo ships carrying new research experiments and supplies, namely the SpaceX Dragon as soon as August and Orbital ATK Cygnus a month or two later, on NASA-contracted commercial resupply missions.

The SpaceX CRS-12 mission will carry investigations ”the crew will work on including a study developed by the Michael J. Fox Foundation of the pathology of Parkinson’s disease to aid in the development of therapies for patients on Earth. The crew will use the special nature of microgravity in a new lung tissue study to advance understanding of how stem cells work and pave the way for further use of the microgravity environment in stem cell research. Expedition astronauts also will assemble and deploy a microsatellite investigation seeking to validate the concept of using microsatellites in low-Earth orbit to support critical operations, such as providing lower-cost Earth imagery in time-sensitive situations such as tracking severe weather and detecting natural disasters.”

Opportunity Starts Historic Descent of Tantalizing Martian Gully to Find Out How Was It Carved

From the precipice of “Perseverance Valley” NASA’s teenaged Red Planet robot Opportunity has begun the historic first ever descent of an ancient Martian gully – that’s simultaneously visually and scientifically “tantalizing” – on an expedition to discern ‘How was it carved?’; by water or other means, Jim Green, NASA’s Planetary Sciences Chief tells Universe Today.

Since water is an indispensable ingredient for life as we know it, the ‘opportunity’ for Opportunity to study a “possibly water-cut” gully on Mars for the first time since they were discovered over four decades ago by NASA orbiters offers a potential scientific bonanza.

“Gullies on Mars have always been of intense interest since first observed by our orbiters,” Jim Green, NASA’s Planetary Sciences Chief explained to Universe Today.

“How were they carved? muses Green. “Water is a natural explanation but this is another planet. Now we have a chance to find out for real!”

Their origin and nature has been intensely debated by researchers for decades. But until now the ability to gather real ‘ground truth’ science by robotic or human explorers has remained elusive.

“This will be the first time we will acquire ground truth on a gully system that just might be formed by fluvial processes,” Ray Arvidson, Opportunity Deputy Principal Investigator of Washington University in St. Louis, told Universe Today.

“Perseverance Valley” is located along the eroded western rim of gigantic Endeavour crater – as illustrated by our exclusive photo mosaics herein created by the imaging team of Ken Kremer and Marco Di Lorenzo.

After arriving at the upper entryway to “Perseverance Valley” the six wheeled rover drove back and forth to gather high resolution imagery of the inner slope for engineers to create a 3D elevation map and plot a safe driving path down – as illustrated in our lead mosaic showing the valley and extensive wheel tracks at left, center and right.

Having just this week notched an astounding 4800 Sols roving the Red Planet, NASA’s resilient Opportunity rover has started driving down from the top of “Perseverance Valley” from the spillway overlooking the upper end of the ancient fluid-carved Martian valley into the unimaginably vast eeriness of alien Endeavour crater.

Water, ice or wind may have flowed over the crater rim and into the crater from the spillway.

“It is a tantalizing scene,” said Opportunity Deputy Principal Investigator Ray Arvidson of Washington University in St. Louis, in a statement. “You can see what appear to be channels lined by boulders, and the putative spillway at the top of Perseverance Valley. We have not ruled out any of the possibilities of water, ice or wind being responsible.”

Toward the right side of this scene is a broad notch in the crest of the western rim of Endeavour Crater. Wheel tracks in that area were left by NASA’s Mars Exploration Rover Opportunity as it observed “Perseverance Valley” from above in the spring of 2017. The valley is a major destination for the rover’s extended mission. It descends out of sight on the inner slope of the rim, extending down and eastward from that notch. The component pancam images for this view from a position outside the crater were taken during the span of June 7 to June 19, 2017, sols 4753 to 4765.

“With the latest drive on sol 4782, Opportunity began the long drive down the floor of Perseverance Valley here on Endeavour crater, says Larry Crumpler, a rover science team member from the New Mexico Museum of Natural History & Science.

“This is rather historic in that it represents the first time that a rover has driven down an apparent water-cut valley on Mars. Over the next few months Opportunity will explore the floor and sides of the valley for evidence of the scale and timing of the fluvial activity, if that is what is represents.”

NASA’s unbelievably long lived Martian robot reached a “spillway” at the top of “Perseverance Valley” in May after driving southwards for weeks from the prior science campaign at a crater rim segment called “Cape Tribulation.”

“Investigations in the coming weeks will “endeavor” to determine whether this valley was eroded by water or some other dry process like debris flows,” explains Crumpler.

“It certainly looks like a water cut valley. But looks aren’t good enough. We need additional evidence to test that idea.”

NASA’s Opportunity rover acquired this Martian panoramic view from a promontory that overlooks Perseverance Valley below – scanning from north to south. It is centered on due East and into the interior of Endeavour crater. Perseverance Valley descends from the right and terminates down near the crater floor in the center of the panorama.

The valley slices downward from the crest line through the rim from west to east at a breathtaking slope of about 15 to 17 degrees – and measures about two football fields in length!

Huge Endeavour crater spans some 22 kilometers (14 miles) in diameter on the Red Planet. Perseverance Valley slices eastwards at approximately the 8 o’clock position of the circular shaped crater. It sits just north of a rim segment called “Cape Byron.”

Why go and explore the gully at Perseverance Valley?

“Opportunity will traverse to the head of the gully system [at Perseverance] and head downhill into one or more of the gullies to characterize the morphology and search for evidence of deposits,” Arvidson elaborated to Universe Today.

“Hopefully test among dry mass movements, debris flow, and fluvial processes for gully formation. The importance is that this will be the first time we will acquire ground truth on a gully system that just might be formed by fluvial processes. Will search for cross bedding, gravel beds, fining or coarsening upward sequences, etc., to test among hypotheses.”

Exploring the ancient valley is the main science destination of the current two-year extended mission (EM #10) for the teenaged robot, that officially began Oct. 1, 2016. It’s just the latest in a series of extensions going back to the end of Opportunity’s prime mission in April 2004.

Before starting the gully descent, Opportunity conducted a walkabout at the top of the Perseverance Valley in the spillway to learn more about the region before driving down.

“The walkabout is designed to look at what’s just above Perseverance Valley,” said Opportunity Deputy Principal Investigator Ray Arvidson of Washington University in St. Louis, in a statwemwent. “We see a pattern of striations running east-west outside the crest of the rim.”

“We want to determine whether these are in-place rocks or transported rocks,” Arvidson said. “One possibility is that this site was the end of a catchment where a lake was perched against the outside of the crater rim. A flood might have brought in the rocks, breached the rim and overflowed into the crater, carving the valley down the inner side of the rim. Another possibility is that the area was fractured by the impact that created Endeavour Crater, then rock dikes filled the fractures, and we’re seeing effects of wind erosion on those filled fractures.”

Having begun the long awaited gully descent, further movements are temporarily on hold since the start of the solar conjunction period which blocks communications between Mars and Earth for about the next two weeks, since Mars is directly behind the sun.

In the meantime, Opportunity will still collect very useful panoramic images and science data while standing still.

The solar conjunction moratorium on commanding extends from July 22 to Aug. 1, 2017.

As of today, July 27, 2017, long lived Opportunity has survived over 4800 Sols (or Martian days) roving the harsh environment of the Red Planet.

Opportunity has taken over 221,625 images and traversed over 27.95 miles (44.97 kilometers.- more than a marathon.

See our updated route map below. It shows the context of the rovers over 13 year long traverse spanning more than the 26 mile distance of a Marathon runners race.

The rover surpassed the 27 mile mark milestone on November 6, 2016 (Sol 4546) and will soon surpass the 28 mile mark.

As of Sol 4793 (July 18, 2017) the power output from solar array energy production is currently 332 watt-hours with an atmospheric opacity (Tau) of 0.774 and a solar array dust factor of 0.534, before heading into another southern hemisphere Martian winter later in 2017. It will count as Opportunity’s 8th winter on Mars.

Meanwhile Opportunity’s younger sister rover Curiosity traverses up the lower sedimentary layers at the base of Mount Sharp.

And NASA continues building the next two robotic missions due to touch down in 2018 and 2020.

NASA as well is focusing its human spaceflight efforts on sending humans on a ‘Journey to Mars’ in the 2030s with the Space Launch System (SLS) mega rocket and Orion deep space crew capsule.

SpaceX Dragon Returns Science Cargo to Earth, Falcon 9 Delivers Massive ‘Epic’ Intelsat Comsat to Orbit – Photo/Video Galley

KENNEDY SPACE CENTER, FL – July has begun with SpaceX maintaining a blistering pace of blasting rockets and spaceships flying to space and returning to Earth for a host of multipronged missions furthering NASA science both on the International Space Station (ISS) and beyond, commercial space endeavors in the US and overseas and fulfilling billionaire founder Elon Musk’s dreams of creating reusable rocketry to slash launch costs and advance humanity’s push to the stars.

On July 2, SpaceX conducted the first launch attempt of the Intelsat 35e telecomsat that ultimately culminated with a spectacularly successful launch on the third try on July 5 at dusk that lit up the Florida Space Coast skies.

A Falcon 9 roared off SpaceX’s seaside launch pad 39A at NASA’s Kennedy Space Center in Florida precisely on time at 7:38 p.m. EDT, or 2338 UTC July 5 carrying the massive Intelsat 35e communications satellite for commercial high speed broadband provider Intelsat.

On July 3, the first reflown SpaceX Dragon cargo freighter returned to Earth with a splashdown in the Pacific Ocean after a month-long stay at the International Space Station.

SpaceX contracted ships recovered Dragon from the ocean and hauled it onto deck for return to Port and handover of the science experiments to NASA and teams of research investigators.

The Dragon CRS-11 spacecraft completed the first re-flight mission of a commercial spacecraft to and from the orbiting laboratory.

The gumdrop shaped Dragon spacecrft brought back more than 4,100 pounds of cargo and research samples gathered by members of the stations multinational crews.

Meanwhile, the doubly ‘flight-proven’ SpaceX Falcon 9 booster from the BulgariaSat-1 launch that propulsoively soft landed upright and intact on the sea going OCISLY drone ship hundreds of mile (km) offshore in the Atlantic Ocean sailed back into Port Canaveral.

After berthing in port, technicians removed its quartet of landing legs and lowered it horizontally for transport back to KSC for refurbishment operations.

Intelsat 35e marks the tenth SpaceX launch of 2017 – establishing a new single year launch record for SpaceX.

The recent BulgariaSat-1 and Iridium-2 missions counted as the eighth and ninth SpaceX launches of 2017.

Including those last two ocean platform landings, SpaceX has now successfully recovered 13 boosters; 5 by land and 8 by sea, over the past 18 months.

Lightfoot, Jr., Senator Marco Rubio and Lockheed Martin CEO Marillyn Hewson inside the Neil Armstrong Operations and Checkout Building at KSC. Credit: Ken Kremer/kenkremer.com

KENNEDY SPACE CENTER, FL – Vice President Mike Pence, during a whirlwind visit to NASA’s Kennedy Space Center in Florida, vowed that America would fortify our leadership in space under the Trump Administration with impressive goals by forcefully stating that “our nation will return to the moon, and we will put American boots on the face of Mars.”

“American will once again lead in space for the benefit and security of all of our people and all of the world,” Vice President Mike Pence said during a speech on Thursday, July 6, addressing a huge crowd of more than 500 NASA officials and workers, government dignitaries and space industry leaders gathered inside the cavernous Vehicle Assembly Building at the Kennedy Space Center – where Apollo/Saturn Moon landing rockets and Space Shuttles were assembled for decades in the past and where NASA’s new Space Launch System (SLS) megarocket and Orion deep space crew capsule will be assembled for future human missions to the Moon, Mars and beyond.

Pence pronounced the bold space exploration goals and a reemphasis on NASA’s human spaceflight efforts from his new perch as Chairman of the newly reinstated National Space Council just established under an executive order signed by President Trump.

“We will re-orient America’s space program toward human space exploration and discovery for the benefit of the American people and all of the world.”

However Pence was short on details and he did not announce any specific plans, timetables or funding during his 25 minute long speech inside the iconic VAB at KSC.

It remains to been seen how the rhetoric will turn to reality and all important funding support.

The Trump Administration actually cut their NASA 2018 budget request by $0.5 Billion to $19.1 Billion compared to the enacted 2017 NASA budget of $19.6 Billion – including cuts to SLS and Orion.

By contrast, the Republican led Congress – with bipartisan support – is working on a 2018 NASA budget of around 19.8 Billion.

“Let us do what our nation has always done since its very founding and beyond: We’ve pushed the boundaries on frontiers, not just of territory, but of knowledge. We’ve blazed new trails, and we’ve astonished the world as we’ve boldly grasped our future without fear.”

“From this ‘Bridge to Space,’ our nation will return to the moon, and we will put American boots on the face of Mars.” Pence declared.

Lined up behind Pence on the podium was the Orion spacecraft flown on Exploration Flight Test-1 (EFT-1) in 2014 flanked by a flown SpaceX cargo Dragon and a mockup of the Boeing CST-100 Starliner crew capsule.

The crewed Dragon and Starliner capsules are being developed by SpaceX and Boeing under NASA contracts as commercial crew vehicles to ferry astronauts to the International Space Station (ISS).

Pence reiterated the Trump Administrations support of the ISS and working with industry to cut the cost of access to space.

Acting NASA Administrator Robert Lightfoot also welcomed Vice President Pence to KSC and thanked the Trump Administration for its strong support of NASA missions.

“Here, of all places, we can see we’re not looking at an ‘and/or proposition’,” Lightfoot said.

“We need government and commercial entities. We need large companies and small companies. We need international partners and our domestic suppliers. And we need academia to bring that innovation and excitement that they bring to the next workforce that we’re going to use to actually keep going further into space than we ever have before.”

After the VAB speech, Pence went on an extensive up close inspection tour of KSC facilities led by Kennedy Space Center Director and former shuttle astronaut Robert Cabana, showcasing the SLS and Orion hardware and infrastructure critical for NASA’s plans to send humans on a ‘Journey to Mars’ by the 2030s.

“We are in a great position here at Kennedy, we made our vision a reality; it couldn’t have been done without the passion and energy of our workforce,” said Kennedy Space Center Director Cabana.

“Kennedy is fully established as a multi-user spaceport supporting both government and commercial partners in the space industry. As America’s premier multi-user spaceport, Kennedy continues to make history as it evolves, launching to low-Earth orbit and beyond.”

Titan’s Lakes are Nice and Calm. The Perfect Spot for a Landing

Ever since the Cassini orbiter and the Huygens lander provided us with the first detailed glimpse of Saturn’s moon Titan, scientists have been eager to mount new missions to this mysterious moon. Between its hydrocarbon lakes, its surface dunes, its incredibly dense atmosphere, and the possibility of it having an interior ocean, there is no shortage of things that are worthy of research.

The only question is, what form would this mission take (i.e. aerial drone, submarine, balloon, lander) and where should it set down? According to a new study led by the University of Texas at Austin, Titan’s methane lakes are very calm and do not appear to experience high waves. As such, these seas may be the ideal place for future missions to set down on the moon.

Their study, which was titled “Surface Roughness of Titan’s Hydrocarbon Seas“, appeared in the June 29th issue of the journal Earth and Planetary Science Letters. Led by Cyril Grima, a research associate at the University of Texas Institute for Geophysics (UTIG), the team behind the study sought to determine just how active the lakes are in Titan’s northern polar region are.

As Grima explained in a University of Texas press release, this research also shed light on the meteorological activity on Titan:

“There’s a lot of interest in one day sending probes to the lakes, and when that’s done, you want to have a safe landing, and you don’t want a lot of wind. Our study shows that because the waves aren’t very high, the winds are likely low.”

Towards this end, Grima and his colleagues examined radar data obtained by the Cassini mission during Titan’s early summer season. This consisted of measurements of Titan’s northern lakes, which included Ontario Lacus, Ligeia Mare, Punga Mare, and Kraken Mare. The largest of the three, Kraken Mars, is estimated to be larger than the Caspian Sea – i.e. 4,000,000 km² (1,544,409 mi²) vs 3,626,000 km²(1,400,000 mi²).

With the help of the Cassini RADAR Team and researchers from Cornell University, the Johns Hopkins University Applied Physics Laboratory (JHUAPL), NASA’s Jet Propulsion Laboratory (JPL) and elsewhere, the team applied a technique known as radar statistical reconnaissance. Developed by Grima, this technique relies on radar data to measure the roughness of surfaces in minute detail.

This technique has also been used to measure snow density and the surface roughness of ice in Antarctica and the Arctic. Similarly, NASA has used the technique for the sake of selecting a landing site on Mars for their Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (Insight) lander, which is scheduled to launch next year.

From this, Grima and his colleagues determined that waves on these lakes are quite small, reaching only 1 cm in height and 20 cm in length. These findings indicate that these lakes would be a serene enough environment that future probes could make soft landings on them and then begin the task of exploring the surface of the moon. As with all bodies, waves on Titan could be wind-driven, triggered by tidal flows, or the result of rain or debris.

As a result, these results are calling into question what scientists think about seasonal change on Titan. In the past, it was believed that summer on Titan was the beginning of moon’s windy season. But if this were the case, the results would have indicated higher waves (the result of higher winds). As Alex Hayes, an assistant professor of astronomy at Cornell University and a co-author on the study, explained:

“Cyril’s work is an independent measure of sea roughness and helps to constrain the size and nature of any wind waves. From the results, it looks like we are right near the threshold for wave generation, where patches of the sea are smooth and patches are rough.”

These results are also exciting for scientists who are hoping to plot future missions to Titan, especially by those who are hoping to see a robotic submarine sent to Titan’s to investigate its lakes for possible signs of life. Other mission concepts involve exploring Titan’s interior ocean, its surface, and its atmosphere for the sake of learning more about the moon’s environment, its organic-rich environment and probiotic chemistry.

And who knows? Maybe, just maybe, these missions will find that life in our Solar System is more exotic than we give it credit before, going beyond the carbon-based life that we are familiar with to include the methanogenic.
