Space Plants in a BRIC.
NASA Commentator Lori Meggs at the Marshall Space Flight Center talks with Sarah Swanson, a researcher at the University of Wisconsin-Madison, who has grown plants on the International Space Station inside a unique container called a BRIC – Biological Research in Canister. The experimenters hope that what they learn from the BRIC experiment can be used to help plants cope with the physical realities of a microgravity environment, where the lack of buoyancy-driven convection can cause low-oxygen conditions around the plant which impede its growth.
Orion's Thermal Protection System.
Jared Vander Kam works as the Orion Thermal Protection System (TPS) manager at NASA's Ames Research Center. Orion's TPS or heat shield is the largest ablative heat shield ever made and is vital technology to helping astronauts safely return to Earth after a Mars mission. At Ames, lots of Arc Jet testing is conducted with very small samples of the ablative material to evaluate how they’ll do on reentry into the earth’s atmosphere. The Orion TPS group is excited about playing such a huge role in this next giant leap NASA is taking by sending humans to Mars and, most importantly safely returning them home.
Space Station Crew Bids Sayonara to Japanese Cargo Ship.
Aboard the International Space Station, Expedition 45 Flight Engineer
Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) used the
station’s Canadarm2 robotic arm to release the unpiloted Japanese
“Kounotori” H-II Transfer Vehicle (HTV-5) Sept. 28, completing its
five-week stay at the complex. The HTV delivered five tons of supplies
and scientific experiments to the outpost following its launch from the
Tanegashima Space Center in southern Japan Aug. 19 and its arrival at
the station Aug. 24.

Making Oxygen On Mars.
Diane Linne, is a Senior Research Engineer at NASA’s Glen Research Center, working on ways to make oxygen on Mars – for rocket fuel and for breathing. Believe it or not, one possible way is with dirt! That’s because we now believe there is quite a bit of water in the soil, either as bound water or as hydrated minerals. Wait ‘till you find out how you get water out of dirt – it’s real “MacGyver-like” ingenuity! This type of real NASA science is enabling the Journey to Mars and, most importantly, ensuring our astronauts can get off Mars and back home to Earth.

NASA Discovers Evidence for Liquid Water on Mars.
A NASA spacecraft circling Mars has found evidence of flowing water
on the Red Planet’s surface – and in our time, not in some dim and more
verdant past.
Humans may like to think Earth has the solar system’s monopoly on water, but a new study reveals that Earth’s close neighbor boasts multiple seeps of salt-laden water that were wet, or at least damp, as recently as last year.Until now, “we thought of the current Mars as a barren, extremely dry and cold desert,” SETI Institute planetary scientist Janice Bishop, who did not take part in the research, said via email. “What is new and exciting here is that this provides evidence for liquid water on Mars in the current environment.”
Eons ago, Mars had enough water to fill enormous lakes and rivers. Scientists prospecting for the wet stuff in recent decades, however, had to content themselves with ice at the planet’s poles, small amounts of water vapor in the atmosphere and water locked up in minerals in the Martian soil. The wet Mars of billions of years ago seemed to have become a desiccated world.But five years ago, researchers spotted mysterious dark streaks running down the warm slopes of Martian craters and mountains. The lines disappeared in the cold season and reappeared in the warm season, like spring freshets on Earth. They looked tantalizingly like a sign of liquid water, but landslides or dust couldn’t be ruled out, study co-author Scott Murchie of the Applied Physics Laboratory said.
So Murchie and his colleagues had NASA’s Mars Reconnaissance Orbiter take a closer look. Along the mysterious lines, the spacecraft detected the signature of waterlogged molecules of perchlorate, chemicals made up of chlorine and oxygen, the scientists report in this week’s Nature Geoscience. Something is moistening Mar’s ample deposits of perchlorate, study leader Lujendra Ojha, a graduate student at the Georgia Institute of Technology, said. And that something must be liquid water.

New NASA images reveal Pluto’s giant ice mountains.
The latest images from Pluto taken by NASA’s New Horizons spacecraft
show amazing new details about the dwarf planet’s atmosphere, weather
patterns and streams of frozen nitrogen. NASA is calling it “a
scientific bonanza.”
A stunning panoramic image of
Pluto’s crescent, backlit by the Sun shining through the world’s hazy
atmosphere, was taken just two months ago by NASA’s New Horizon
spacecraft,and downloaded to Earth on September 13. It is the first
spacecraft to fly by Pluto and record images of the intriguing icy dwarf
planet.
The Real Martians.
During an event on Sept. 17 at NASA headquarters, Administrator Charlie Bolden and other agency officials discussed how the film “The Martian” uses real science from the exploration of Mars by NASA to make the movie. The discussion also touched on how the film’s story, which is set in the 2030s, when NASA astronauts are regularly traveling to Mars and living on the surface, closely matches NASA’s story and efforts to land humans on Mars by that time. NASA collaborated on this film with 20th Century Fox Entertainment, providing guidance on production design and serving as technical consultants.
Connecting Space to Village.
During an event hosted by the U.S. Agency for International Development (USAID), NASA Administrator Charlie Bolden and astronauts Terry Virts of NASA and Samantha Cristoforetti or ESA, who recently returned from a mission aboard the International Space Station, discussed the importance of the SERVIR project – a joint venture between the agencies that provides state-of-the-art, satellite-based Earth monitoring, imaging and mapping data, geospatial information, and other products to help improve environmental decision-making abilities for officials in developing countries.

Space Station Commander Pays Tribute to a “Hero of America”
Aboard the International Space Station, Expedition 45 Commander Scott
Kelly of NASA paid tribute to a researcher at NASA’s Marshall Space
Flight Center in Huntsville, Alabama as part of ABC’s “Good Morning,
America” “Above and Beyond” series. The son of a preacher, Trent Griffin
and his six brothers and sisters were raised to reach for the stars and
improve their community with them. Griffin did just that, eventually
becoming a NASA physicist at the Marshall Flight Space Center in his
hometown, working on space station life support systems and building a
new glove box for conducting research in orbit. After coming across
five siblings that shared a single bicycle in Huntsville, Griffin bought
several used bikes, refurbished them and donated them to children in
the community. For his service, Griffin was honored by Kelly and the
hosts of the “Good Morning, America” program.
