Just in time for the holidays, NASA’sCuriosity rover is celebrating Christmas 2015 at a Red Planet Paradise – spectacular “Namib Dune.” And she marked the occasion by snapping her first ever color self-portrait with the mast mounted high resolution Mastcam 34 mm camera.
NASA managers have just made the difficult but unavoidable decision to scrub the planned March 2016 launch of the InSight lander, the agency’s next mission to Mars, by at least two years because of a vacuum leak that was just detected in the probes flawed seismometer instrument which cannot be fixed in time.
After many months of painstaking driving, NASA’s Curiosity Mars rover has reached the edge of a massive field of spectacular rippled sand dunes located at the base of Mount Sharp that range up to two stories tall. And she has now begun humanity’s first up-close investigation of currently active sand dunes anywhere beyond Earth.
NASA’s Curiosity rover is on the Martian road to soon start the first ever study of currently active sand dunes anywhere beyond Earth. The dunes are located nearby, at the foothills of Mount Sharp, and Curiosity is due to arrive for an up close look in just a few days to start her unique research investigations.
The eerily dark dunes, named the “Bagnold Dunes,” skirt the northwestern flank of Mount Sharp. Ascending and diligently exploring the sedimentary layers of Mount Sharp is the primary goal of the mission.
“The ‘Bagnold Dunes’ are tantalizingly close,” says Ken Herkenhoff, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in a mission update on Wednesday, Nov. 18.
The “Bagnold Dunes” have been quite noticeable in numerous striking images taken from Marsorbit, during the vehicles nail biting ‘7 Minutes of Terror’ descent from orbit, as well as in thousands upon thousands of images taken by Curiosity herself as the robot edged ever closer during her over three year long traverse across the floor of the Gale Crater landing site.
Curiosity must safely cross the expansive dune field before climbing Mount Sharp.
Although multiple NASA rovers, including Curiosity, have studied much smaller Martian sand ripples or drifts, none has ever visited and investigated up close these types of large dunes that range in size as tall as a two story building or more and as wide as a football field or more.
Moreover the Martian dunes are shifting even today.
“Shifting sands lie before me,” Curiosity tweeted. “Off to image, scoop and scuff active dunes on Mars. I’ll be the first craft to visit such dunes beyond Earth!”
“The Bagnold Dunes are active: Images from orbit indicate some of them are migrating as much as about 3 feet (1 meter) per Earth year. No active dunes have been visited anywhere in the solar system besides Earth,” notes NASA.
Curiosity is currently only some 200 yards or meters away from the first dune she will investigate, simply named “Dune 1.”
As the rover approaches closer and closer, the dune research campaign is already in progress as she snaps daily high resolution images and gathers measurements of the area’s wind direction and speed.
“We’ve planned investigations that will not only tell us about modern dune activity on Mars but will also help us interpret the composition of sandstone layers made from dunes that turned into rock long ago,” said Bethany Ehlmann of the California Institute of Technology and NASA’s Jet Propulsion Laboratory, in Pasadena, California, in a statement.
After arriving at the dune, the team will command Curiosity to scoop up samples for analysis by the rover’s pair of miniaturized chemistry instruments inside its belly. It will also scuff the dune with a wheel to examine and compare the surface and interior physical characteristics.
The dark dunes are informally named after British military engineer Ralph Bagnold (1896-1990), who conducted pioneering studies of the effect of wind on motion of individual particles in dunes on Earth. Curiosity will carry out “the first in-place study of dune activity on a planet with lower gravity and less atmosphere.”
Although the huge Bagnold dunes are of great scientific interest, the team will also certainly exercise caution in maneuvering the car sized six wheel robot.
Recall that NASA’s smaller golf cart Spirit Mars rover perished a few years back – albeit over 6 years into her 3 month mission – when the robot became unexpectedly mired in a nearly invisible sand ripple from which she was unable to escape.
Likewise, sister Opportunity got stuck in a sand ripple earlier in her mission that took the engineering team weeks of painstaking effort to extricate from a spot subsequently named ‘Purgatory’ that resulted in many lessons learned for future operations.
Opportunity is still hard at work – currently exploring Marathon Valley – nearly a dozen years into her planned 3 month mission.
Based on orbital observations by the CRISM and HiRISE instruments aboard NASA’s Mars Reconnaissance Orbiter, the science team has concluded that the Bagnold Dunes are mobile and also have an uneven distribution of minerals, such as olivine.
“We will use Curiosity to learn whether the wind is actually sorting the minerals in the dunes by how the wind transports particles of different grain size,” Ehlmann said.
“If the Bagnold campaign finds that other mineral grains are sorted away from heavier olivine-rich grains by the wind’s effects on dune sands, that could help researchers evaluate to what extent low and high amounts of olivine in some ancient sandstones could be caused by wind-sorting rather than differences in alteration by water,” say researchers.
“These dunes have a different texture from dunes on Earth,” said team member Nathan Bridges, of the Johns Hopkins University’s Applied Physics Laboratory, Laurel, Maryland.
“The ripples on them are much larger than ripples on top of dunes on Earth, and we don’t know why. We have models based on the lower air pressure. It takes a higher wind speed to get a particle moving. But now we’ll have the first opportunity to make detailed observations.”
Last month Curiosity conducted her eighth drill campaign for sample chemical analysis at the ‘Big Sky’ site, before moving on to ‘Greenhorn’. Big Sky was an area of cross-bedded sandstone rock in the Stimson geological unit on the lower slopes of Mount Sharp.
Curiosity has already accomplished her primary objective of discovering a habitable zone on the Red Planet – at the Yellowknife Bay area – that contains the minerals necessary to support microbial life in the ancient past when Mars was far wetter and warmer billions of years ago.
As of today, Sol 1168, November 19, 2015, she has driven over 6.9 miles (11.1 kilometers) kilometers and taken over 282,100 amazing images.

Just shy of an unfathomable 4200 Sols traversing ravishing alien terrain on the Red Planet, the longest living ‘Martian’ – NASA’s robot ‘Opportunity’ – is driving between “lily pads” down steep walled Marathon Valley in search of life giving sun that enables spectacular science yielding clues to Marswatery past. All this as she strives to survive utterly harsh climate extremes, because ‘winter is coming’ for her seventh time on the fourth rock from the sun!
“Opportunity is driving east and southeast down Marathon Valley, bisecting the region in which we detect smectites [clay minerals] using CRISM [spectrometer] data,” Opportunity Deputy Principal Investigator Ray Arvidson, of Washington University in St. Louis, told Universe Today.
As NASA’s Opportunity rover approaches the 12th anniversary of landing on Mars, her greatest science discoveries yet are likely within grasp in the coming months since she has successfully entered Marathon Valley from atop a Martian mountain and is now prospecting downhill for outcrops of water altered clay minerals.
The valley is the gateway to alien terrain holding significant caches of the water altered minerals that formed under environmental conditions conducive to support Martian microbial life forms, if they ever existed. But as anyone who’s ever climbed down a steep hill knows, you have to be extra careful not to slip and slide and break something, no matter how beautiful the view is – Because no one can hear you scream on Mars! See the downward looking valley view above.
After a years long Martian mountain climbing and mountain top exploratory trek, Opportunity entered a notch named Marathon Valley from atop a breathtakingly scenic ridge overlook atop the western rim of Endeavour Crater.
Marathon Valley measures about 300 yards or meters long and cuts downhill through the west rim of Endeavour crater from west to east. Endeavour crater spans some 22 kilometers (14 miles) in diameter.
See our photo mosaics illustrating Opportunity’s view around and about Marathon Valley and Endeavour Crater, created by the image processing team of Ken Kremer and Marco Di Lorenzo.
Our mosaic above affords a downward looking view from Marathon Valley on Sol 4144, Sept. 20. It uniquely combines raw images from the hazcam and navcam cameras to gain a wider perspective panoramic view of the steep walled valley, and also shows the rover at work stretching out the robotic arm to potential clay mineral rock targets at left. Opportunity’s shadow and wheel tracks are visible at right.
In late July, Opportunity began the decent into the valley from the western edge and started investigating scientifically interesting rock targets by conducting a month’s long “walkabout” survey ahead of the upcoming frigid Martian winter – the seventh since touchdown at Meridiani Planum in January 2004.
The walkabout was done to identify targets of interest for follow up scrutiny in and near the valley floor. Opportunity’s big sister Curiosity conducted a similarly themed “walkabout” at the base of Mount Sharp near her landing site located on the opposite side of the Red Planet.
“The valley is somewhat like a chute directed into the crater floor, which is a long ways below. So it is somewhat scary, but also pretty interesting scenery,” writes Larry Crumpler, a science team member from the New Mexico Museum of Natural History & Science, in a mission update.
“Its named Marathon Valley because the rover traveled one marathon’s distance to reach it,” Prof. Ray Arvidson, the rover Deputy Principal Investigator of Washington University told Universe Today.
The NASA rover exceeded the distance of a marathon on the surface of Mars on March 24, 2015, Sol 3968. Opportunity has now driven over 26.46 miles (42.59 kilometers) over nearly a dozen Earth years.
Now for the first time in history, a human emissary has arrived to conduct an up close inspection of and elucidate clues into this regions potential regarding Martian habitability.
The ancient, weathered slopes around Marathon Valley hold a motherlode of ‘phyllosilicate’ clay minerals, based on data obtained from the extensive Mars orbital measurements gathered by the CRISM spectrometer on NASA’s Mars Reconnaissance Orbiter (MRO) – accomplished earlier at the direction of Arvidson.
Initially the science team was focused on investigating the northern region of the valley while the sun was still higher in the sky and generating more power for research activities from the life giving solar arrays.
“We have detective work to do in Marathon Valley for many months ahead,” said Opportunity Deputy Principal Investigator Ray Arvidson, of Washington University in St. Louis.
But now that the rover is descending into a narrow valley with high walls, the rovers engineering handlers back on Earth have to exercise added caution regarding exactly where they send the Opportunity on her science forays during each sols drive, in order to maintain daily communications.
The high walls to the north and west of the valley ridgeline has already caused several communications blackouts for the “low-elevation Ultra-High-Frequency (UHF) relay passes to the west,” according to the JPL team controlling the rover.
Indeed on two occasions in mid September – coinciding with the days just before and after our Sol 4144 (Sept. 20) photo mosaic view above, “no data were received as the orbiter’s flight path was below the elevation on the valley ridgeline.
On Sept 17 and Sept. 21 “the high ridgeline of the valley obscured the low-elevation pass” and little to no data were received. However the rover did gather imagery and spectroscopic measurements for later transmission.
Now that winter is approaching the rover is moving to the southern side of Marathon Valley to soak up more of the sun’s rays from the sun-facing slope and continue research activities.
“During the Martian late fall and winter seasons Opportunity will conduct its measurements and traverses on the southern side of the valley,” says Arvidson.
“When spring arrives the rover will return to the valley floor for detailed measurements of outcrops that may host the clay minerals.”
The shortest-daylight period of this seventh Martian winter for Opportunity will come in January 2016.
As of today, Sol 4168, Oct, 15, 2015 Opportunity has taken over 206,300 images and traversed over 26.46 miles (42.59 kilometers).

Looking up from beneath the enlarged exhaust hole of the Mobile Launcher to the 380 foot-tall tower astronauts will ascend as their gateway for missions to the Moon, Asteroids and Mars. The ML will support NASA’s Space Launch System (SLS) and Orion spacecraft during Exploration Mission-1 at NASA’s Kennedy Space Center in Florida. Credit: Ken Kremer/kenkremer.com
“We just finished up major structural steel modifications to the ML, including work to increase the size of the rocket exhaust hole,” Eric Ernst, NASA Mobile Launch project manager, told Universe Today during an exclusive interview and inspection tour up and down the Mobile Launcher.
Construction workers are hard at work upgrading and transforming the 380-foot-tall, 10.5-million-pound steel structure into the launcher for SLS and Orion – currently slated for a maiden blastoff no later than November 2018 on Exploration Mission-1 (EM-1).
“And now we have just started the next big effort to get ready for SLS.”
SLS and Orion are NASA’s next generation human spaceflight vehicles currently under development and aimed at propelling astronauts to deep space destinations, including the Moon and an asteroid in the 2020s and eventually a ‘Journey to Mars’ in the 2030s.
The mobile launcher was originally built several years ago to accommodate NASA’s less powerful, lighter and now cancelled Ares-1 rocket. It therefore requires extensive alterations to accommodate the vastly more powerful and heavier SLS rocket.
“The ML was initially developed for Ares 1, a much smaller rocket,” Ernst explained to Universe Today.
“So the exhaust hole was much smaller.”
Whereas the Ares-1 first stage booster was based on using a single, more powerful version of the Space Shuttle Solid Rocket Boosters, the SLS first stage is gargantuan and will be the most powerful rocket the world has ever seen.
The SLS first stage comprises two shuttle derived solid rocket boosters and four RS-25 power plants recycled from their earlier life as space shuttle main engines (SSMEs). They generate a combined 8.4 million pounds of thrust – exceeding that of NASA’s Apollo Saturn V moon landing rocket.
Therefore the original ML exhaust hole had to be gutted and nearly tripled in width.
“The exhaust hole used to be about 22 x 22 feet,” Ernst stated.
“Since the exhaust hole was much smaller, we had to deconstruct part of the tower at the base, in place. The exhaust hole had to be made much bigger to accommodate the SLS.”
Construction crews extensively reworked the exhaust hole and made it far wider to accommodate SLS compared to the smaller one engineered and already built for the much narrower Ares-1, which was planned to generate some 3.6 million pounds of thrust.
“So we had to rip out a lot of steel,” Mike Canicatti, ML Construction Manager told Universe Today.
“For the exhaust hole [at the base of the tower], lots of pieces of [existing] steel were taken out and other new pieces were added, using entirely new steel.”
“The compartment for the exhaust hole used to be about 22 x 22 feet, now it’s about 34 x 64 feet.”
In fact this involved the demolition of over 750 tons of old steel following by fabrication and installation of more than 1,000 tons of new steel. It was also reinforced due to the much heavier weight of SLS.
“It was a huge effort and structural engineers did their job. The base was disassembled and reassembled in place” – to enlarge the exhaust hole.
“So basically we gutted major portions of the base out, put in new walls and big structural girders,” Ernst elaborated.
“And we just finished up that major structural steel modification on the exhaust hole.”
Meanwhile the 380 foot-tall tower that future Orion astronauts will ascend was left in place.
“The tower portion itself did not need to be disassembled.”
The Ares rockets originally belonged to NASA’s Constellation program, whose intended goal was returning American astronauts to the surface of the Moon by 2020.
Ares-1 was slated as the booster for the Orion crew capsule. However, President Obama cancelled Constellation and NASA’s Return to the Moon soon after entering office.
Since then the Obama Administration and Congress worked together in a bipartisan manner together to fashion a new space hardware architecture and granted approval for development of the SLS heavy lift rocket to replace the Ares-1 and heavy lift Ares-5.
Sending astronauts on a ‘Journey to Mars’ is now NASA’s agency wide and overarching goal for the next few decades of human spaceflight.
But before SLS can be transported to its launch pad at Kennedy’s Space Launch Complex 39-B for the EM-1 test flight the next big construction step has to begin.
“So now we have just started the next big effort to get ready for SLS.”
This involves installation of Ground Support Equipment (GSE) and a wide range of launch support services and systems to the ML.
“The next big effort is the GSE installation contract,” Ernst told me.
“We have about 40+ ground support and facility systems to be installed on the ML. There are about 800 items to be installed, including about 300,000-plus feet of cable and several miles of piping and tubing.”
“So that’s the next big effort to get ready for SLS. It’s about a 1.5 year contract and it was just awarded to J.P. Donovan Construction Inc. of Rockledge, Florida.”
“The work just started at the end of August.”
NASA currently plans to roll the ML into the Vehicle Assembly Building in early 2017 for stacking of SLS and Orion for the EM-1 test flight.
The SLS/Orion mounted stack atop the ML will then roll out to Space Launch Complex 39B for the 2018 launch from the Kennedy Space Center.
Pad 39B is also undergoing radical renovations and upgrades, transforming it from its use for NASA’s now retired Space Shuttle program into a modernized 21st century launch pad. Watch for my upcoming story.

These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are indeed formed by liquid water. The blue color seen upslope of the dark streaks are thought not to be related to their formation, but instead are from the presence of the mineral pyroxene. The image is produced by draping an orthorectified (Infrared-Red-Blue/Green(IRB)) false color image (ESP_030570_1440) on a Digital Terrain Model (DTM) of the same site produced by High Resolution Imaging Science Experiment (University of Arizona).

NASA and Mars planetary scientists announced today (Sept. 28) that salty “liquid water flows intermittently” across multiple spots on the surface of today’s Mars – trumpeting a major scientific discovery with far reaching implications regarding the search for life beyond Earth and bolstering the chances for the possible existence of present day Martian microbes.
Utilizing spectroscopic measurements and imaging gathered by NASA’s Mars Reconnaissance Orbiter (MRO), researchers found the first strong evidence confirming that briny water flows on the Red Planet today along dark streaks moving downhill on crater slopes and mountain sides, during warmer seasons.
“Mars is not the dry, arid planet that we thought of in the past. Today we announce that under certain circumstances, liquid water has been found on Mars,” said Jim Green, NASA Planetary Science Director at NASA Headquarters, at a media briefing held today, Sept 28.
“When you look at Earth, water is an essential ingredient. Everywhere we go where there’s liquid water, whether its deep in the Earth or in the arid regions, we find life. This is tremendously exciting.”
“We haven’t been able to answer the question – does life exist beyond Earth? But following the water is a critical element of that. We now have great opportunities to be in the right locations on Mars to thoroughly investigate that,” Green elaborated.
“Water! Strong evidence that liquid water flows on present-day Mars,” NASA officials tweeted about the discovery.
The evidence comes in the form of the detection of mysterious dark streaks, as long as 100 meters, showing signatures of hydrated salt minerals periodically flowing in liquid water down steep slopes on the Red Planet that “appear to ebb and flow over time.”
The source of the water is likely from the shallow subsurface or possibly absorbed from the atmosphere.
Water is a key prerequisite for the formation and evolution of life as we know it. So the new finding significantly bolsters the chances that present day extant life could exist on the Red Planet.
“Our quest on Mars has been to ‘follow the water,’ in our search for life in the universe, and now we have convincing science that validates what we’ve long suspected,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington.
“This is a significant development, as it appears to confirm that water — albeit briny — is flowing today on the surface of Mars.”
“This increases the chance that life could exist on Mars today,” noted Grunsfeld.
The data were gathered by and the conclusions are based on using two scientific instruments – the high resolution imaging spectrometer on MRO known as High Resolution Imaging Science Experiment (HiRISE), as well as MRO’s mineral mapping Compact Reconnaissance Imaging Spectrometer for Mars (CRISM).
The mysterious dark streaks of downhill flows are known as recurring slope lineae (RSL).
They were first detected in 2010 at dozens of sites on the sun facing slopes of deep craters by Lujendra Ojha, then a University of Arizona undergraduate student.
The new finding is highly significant because until today’s announcement, there was no strong evidence that liquid water could actually exist on the Martian surface because the atmospheric pressure was thought to be far too low – its less than one percent of Earth’s.
The flow of water is occasional and not permanent, seasonally variable and dependent on having just the right mix of atmospheric, temperature and surface conditions with salt deposits on Mars.
Portions of Mars were covered with an ocean of water billions of years ago when the planet was far warmer and more hospitable to life. But it underwent a dramatic climate change some 3 billion years ago and lost most of that water.
The RSL with flowing water appear in at least three different locations on Mars – including Hale crater, Horowitz crater and Palikir crater – when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius). They appear during warm seasons, fade in cooler seasons and disappear during colder times.
Pure surface water ice would simply sublimate and evaporate away as the temperature rises. Mixing in surface salts lowers the melting point of ice, thereby allowing the water to potentially liquefy on Mars surface for a certain period of time rather than sublimating rapidly away.
“These are dark streaks that form in late spring, grow through the summer and then disappear in the fall,” said Michael Meyer lead scientist for the Mars Exploration Program at NASA Headquarters, at the media briefing.
Years of painstaking effort and laboratory work was required to verify and corroborate the finding of flowing liquid water.
“It took multiple spacecraft over several years to solve this mystery, and now we know there is liquid water on the surface of this cold, desert planet,” said Meyer. “It seems that the more we study Mars, the more we learn how life could be supported and where there are resources to support life in the future.”
Along with the media announcement, the researchers published their findings today in a refereed scientific paper in the Sept. 28 issue of Nature Geoscience.
“We found the hydrated salts only when the seasonal features were widest, which suggests that either the dark streaks themselves or a process that forms them is the source of the hydration. In either case, the detection of hydrated salts on these slopes means that water plays a vital role in the formation of these streaks,” said Lujendra Ojha, now at the Georgia Institute of Technology (Georgia Tech) in Atlanta, and lead author of the Sept. 28 publication in Nature Geoscience.
The scientists “interpret the spectral signatures as caused by hydrated minerals called perchlorates.”
Ojha said the chemical signatures from CRISM were most consistent with the detection of mixtures of magnesium perchlorate, magnesium chlorate and sodium perchlorate, based on lab experiments.
“Some perchlorates have been shown to keep liquids from freezing even when conditions are as cold as minus 94 degrees Fahrenheit (minus 70 Celsius).”
Perchlorates have previously been detected in Martian soil by two of NASA’s surface missions – the Phoenix lander and the Curiosity rover. There is also some evidence that NASA’s Viking missions in the 1970s measured signatures of these salts.
On Earth concentration of perchlorates are found in deserts.
This also marks the first time perchlorates have been identified from Mars orbit.
So NASA astronaut Mark Kelly exclaimed that he was also super excited about the findings, from his perch serving as Commander aboard the International Space Station (ISS), where he is a member of the first ever “1 Year ISS Mission Crew” aimed at learning how the human body will adapt to the long term missions required to send astronauts to Mars and back.
“One reason why NASA’s discovery of liquid water on #Mars is so exciting: we know anywhere there’s water on Earth, there’s some form of life,” Kelly tweeted today from on board the ISS, upon hearing today’s news.
The discovery of liquid water on Mars could also be a boon to future astronauts who could use it as a natural resource to ‘live off the land’ for sustenance and to make rocket fuel.
“If going to Mars on my Year In Space, I’d arrive soon to find water! H20 > rocket fuel, which means I could find my way back home too!,” Kelly wrote on his Facebook page.
“When most people talk about water on Mars, they’re usually talking about ancient water or frozen water,” Ojha explained.
“Now we know there’s more to the story. This is the first spectral detection that unambiguously supports our liquid water-formation hypotheses for RSL.”

The excitement is building for the worldwide movie premiere of ‘The Martian’ on Oct. 2.
Based on the bestselling book by Andy Weir, ‘The Martian’ tells the story of how NASA astronaut Mark Watney, played by Matt Damon, is accidentally stranded on the surface of Mars during a future manned expedition, after a sudden and unexpectedly fierce dust storm forces the rest of the crew to quickly evacuate after they believe he is dead.
In the video above, Matt Damon discusses NASA’s ongoing real life efforts focused on turning science fiction dreams into reality and sending astronauts to Mars.
Watney actually survived the storm but lost contact with NASA. The film recounts his ingenious years long struggle to survive, figure out how to tell NASA he is alive and send a rescue crew before he starves to death on a planet where nothing grows. Watney’s predicament is a survival lesson to all including NASA.
‘The Martian’ was written by Andy Weir in 2010 and has now been produced as a major Hollywood motion picture starring world famous actor Matt Damon and directed by the world famous director Ridley Scott from 20th Century Fox.
NASA’s overriding strategic goal is to send humans on a ‘Journey to Mars’ by the 2030s.
‘The Martian’ is a rather realistic portrayal of how NASA might accomplish the ‘Journey to Mars.’
“Sending people to Mars and returning them safely is the challenge of a generation,” says Damon in the video.
“The boot prints of astronauts will follow the rover tracks [of NASA’s Curiosity rover] thanks to innovations happening today.”
The current six person crew serving aboard the ISS even got a sneak preview of The Martian this past weekend!
Gleeful NASA astronaut Scott Kelly, commander of the Expedition 45 crew, just tweeted a photo of the crew watching ‘The Martian’ while soaring some 250 miles (400 kilometers) above Earth.
“Watched @MartianMovie on @Space_Station last night! Today working towards our #JourneyToMars during my #YearInSpace!” tweeted NASA astronaut Scott Kelly.
Kelly comprises one half of the first ever ‘1 Year ISS Crew’ along with Russian cosmonaut Mikhail Kornienko, aimed at determining the long term physical and psychological effects on the human body of people living and working in the weightlessness of space.
The 1 Year ISS mission is an important data gathering milestone on the human road to Mars since the round trip time to the Red Planet and back will take approximately 3 years or more.
