Competition for hypersonic vehicles resumes
Moscow (Voice of Russia) Jan 21, 2013 – The Russian Defence Ministry will start testing advanced hypersonic missiles in the coming summer. At present, Russia is conducting research in several areas of developing hypersonic technology, but it’s unclear which will be successful. The work on hypersonic vehicles conducted by the Soviet Union and the U.S. during the Cold War was suspended after it was ended. But it has restarted now. … more
Martian Crater May Once Have Held Groundwater-Fed Lake
Pasadena CA (JPL) Jan 21, 2013 – A NASA spacecraft is providing new evidence of a wet underground environment on Mars that adds to an increasingly complex picture of the Red Planet’s early evolution. The new information comes from researchers analyzing spectrometer data from NASA’s Mars Reconnaissance Orbiter, which looked down on the floor of McLaughlin Crater. The Martian crater is 57 miles (92 kilometers) in diameter a … more

Titan Gets a Dune “Makeover”
Greenbelt MD (SPX) Jan 21, 2013 – Titan’s siblings must be jealous. While most of Saturn’s moons display their ancient faces pockmarked by thousands of craters, Titan – Saturn’s largest moon – may look much younger than it really is because its craters are getting erased. Dunes of exotic, hydrocarbon sand are slowly but steadily filling in its craters, according to new research using observations from NASA’s Cassini spacecraft. … more

US scientists find evidence of ancient Martian lake
Washington (AFP) Jan 20, 2013 – A US spacecraft orbiting Mars has provided evidence of an ancient crater lake fed by groundwater, adding further support to theories that the Red Planet may once have hosted life, NASA said Sunday. Spectrometer data from NASA’s Mars Reconnaissance Orbiter (MRO) shows traces of carbonate and clay minerals usually formed in the presence of water at the bottom of the 1.4-mile (2.2-kilometer) de … more






Landsat Senses a Disturbance in the Forest
Greenbelt MD (SPX) Jan 20, 2013 – A new way of studying and visualizing Earth science data from a NASA and U.S. Geological Survey satellite program is resulting in, for the first time, the ability to tease out the small events that can cause big changes in an ecosystem. Called LandTrendr, this computer program is able to find patterns previously buried within vast amounts of scientific data. Still in development, it’s alre … more

An Astronaut’s Guide
Houston TX (SPX) Jan 20, 2013 – Humans make rather poor beasts of burden. Fortunately, nowadays heavy loads are pretty much relegated to machines, saving our spines for recreational activities like donning backpacks and heading into the wilderness. Speaking of which, the suspension system for backpacks-the part that connects the load to our bodies through a series of straps-is relevant to our attempts to keep our muscles and b … more
