The Hayabusa capsule and bus entered the Earth's atmosphere over Woomera, Australia, on June 13 at 11:21 p.m. local time. From the perspective of NASA's DC-8 airborne observation team, the capsule moved below and slightly ahead of the bus and stayed clear of the spectacular breakup of the bus. After the bus had disintegrated, the capsule continued to create a wake, b

Six hundred recent observations of the Mars landscape from an orbiting telescopic camera include scenes of sinuous gullies, geometrical ridges and steep cliffs.Each of the 600 newly released observations from the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter covers an area of several square miles on Mars and reve

Rocks examined by NASA's Spirit Mars Rover hold evidence of a wet, non-acidic ancient environment that may have been favorable for life. Confirming this mineral clue took four years of analysis by several scientists. An outcrop that Spirit examined in late 2005 revealed high concentrations of carbonate, which originates in wet, near-neutral conditions, but dissolves
