A European-Russian spacecraft headed out from our humble little planet to space today, in search for life on Mars.
Mixed emotions. That's what NASA astronaut Scott Kelly says he's feeling upon returning to Earth after 340 days on the International Space Station. Read the rest
NASA reports that astronaut and Expedition 46 Commander Scott Kelly and his Russian counterpart Mikhail Kornienko have returned to Earth Tuesday night, after a historic 340-day mission aboard the International Space Station. The space travelers touched down in Kazakhstan at 11:26 p.m. EST (10:26 a.m. March 2 Kazakhstan time).
NASA has released recordings of weird sounds Apollo 10 astronauts heard while flying around the far side of the moon, and the crew responding to the strange phenomenon.
Mitchell was the sixth human to walk on the moon. He died Thursday night after a short illness. It was exactly one day before the 45th anniversary of the day he landed in the Moon's hilly Fra Mauro region, with crewmate Alan Shepard.
Mitchell was into the paranormal, and the possibility that ESP (psychic communication) could help humans stay connected out in space.
Famous for attempting an experiment in extra-sensory perception on his way back from the moon, Mitchell founded the Institute of Noetic Sciences in 1973 "to support consciousness research and promote awareness of evolving human consciousness," the family said in a statement released by the Astronaut Scholarship Foundation.
Andrew Chaikin, author of "A Man On The Moon -- The Voyages Of The Apollo Astronauts," said in a recent interview with CBS News that Mitchell was "super bright" and "an intellectual."
"Just a real lover of ideas," Chaikin said. "It shows in his post-NASA career because he pursued this question of consciousness and the nature of consciousness. On his flight, he had kind of a mountain-top experience where on the flight home, looking at the Earth, he felt that he was experiencing the universe as an intelligent entity, almost an organism. And that really changed him."
Here are NASA Administrator Charles Bolden's remarks on his death:
NASA astronaut Scott Kelly demonstrates ping pong with a sphere of water on the International Space Station. From NASA:
The paddles are polycarbonate laser etched so that the surfaces are actually arrays of 300 micrometer posts (0.3mm). The surfaces were then spray coated with a Teflon coat. The combined effects of surface roughness and non-wettability produce a super-hydrophobic surface capable of preventing water adhesion in dynamic processes. The larger the drop, the less force it takes to break it up. The smaller the drop, the harder you can hit it. Scott is demonstrating about a 4 mL drop (over 100 times larger than a rain drop).

NASA just released this beautiful composite infrared view of Saturn's moon Titan. The Cassini spacecraft captured the image last month during its flyby about 6,200 miles above the moon's surface. From NASA:

The view looks toward terrain that is mostly on the Saturn-facing hemisphere of Titan. The scene features the parallel, dark, dune-filled regions named Fensal (to the north) and Aztlan (to the south), which form the shape of a sideways letter "H."
Several places on the image show the surface at higher resolution than elsewhere. These areas, called subframes, show more detail because they were acquired near closest approach. They have finer resolution, but cover smaller areas than data obtained when Cassini was farther away from Titan.

NASA's Solar Dynamics Observatory (SDO) in orbit keeps a constant vigil on the Sun to help us understand how solar variations impact life on Earth. Launched in 2010, the SDO is part of NASA's Living With a Star (LWS) Program. NASA just released this magnificent 4K video shot by the SDO of our star's nuclear fire. It's titled "Thermonuclear Art."
Geoff Marcy, a famous and respected American astronomer, has announced his intention to step down as a faculty member at the University of California, Berkeley, according to an email obtained by BuzzFeed News.
Marcy also works with NASA on the search for extraterrestrial life, via the NASA Kepler Mission.
Buzzfeed first broke today's news of Marcy's plans to step aside. It is the first real fallout he's facing from sexual harassment claims that the reported victims say were ignored for years.
Why would those claims be ignored by UC Berkeley? Because Marcy is kind of a big deal in the field of astronomy, and his name meant money for the struggling California academic institution. Read the rest
