NASA's NuSTAR Ships To Vandenberg For March 14 Launch
2012-01-26 06:41:18

NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, shipped to Vandenberg Air Force Base, Calif., on Tuesday, to be mated to its Pegasus launch vehicle. The observatory will detect X-rays from objects ranging from our sun to giant black holes billions of light-years away. It is scheduled to launch March 14 from an aircraft operating out of Kwajalein Atoll in the Marshall Islands. "The NuSTAR mission is unique because it will be the first NASA mission to focus X-rays in the high-energy...

After 16 years in space, NASA's Rossi X-ray Timing Explorer (RXTE) has made its last observation. The satellite provided unprecedented views into the extreme environments around white dwarfs, neutron stars and black holes. RXTE sent data from its last science observation to the ground early on Jan. 4. After performing engineering tests, controllers at NASA's Goddard Space Flight Center in Greenbelt, Md., successfully decommissioned the satellite on Jan. 5. RXTE far exceeded its original...

GALEX Finds Stellar Extremophiles
2011-11-08 10:03:53

[ Watch the Video ] Back in the 1970s, biologists were amazed to discover a form of life they never expected.  Tiny microorganisms with ancient DNA were living in the hot springs of Yellowstone National Park.  Instead of dissolving in the boiling waters, the microbes were thriving, ringing the springs with vibrant color. Scientists coined the term extremophile, which means "extreme-loving", to describe the creatures--and the hunt was on for more.  Soon, extremophiles were...

NASA has selected 11 science proposals for evaluation as potential future science missions. The proposals outline prospective missions to study the Earth's atmosphere, the sun, the Milky Way galaxy, and Earth-like planets around nearby stars. The selections were made from responses to Announcements of Opportunity for Explorer Missions and Explorer Missions of Opportunity released by the agency last November. The proposals were judged to have the best science value and feasible development...
