NASA Ames: On August 25, 2009 from 1:00 p.m. until 2:30 p.m., Ames Research Center will conduct a ceremonial groundbreaking and dedication event for what we expect will become the highest performing building in the federal government.
NASA and the Department of Energy have completed tests on several fission surface power components within the last few weeks. The agencies are researching technologies that could enable possible use of nuclear power on the surface of the moon and Mars. Nuclear power is part of the range of options that are being examined for potential human missions on the moon and Mars.
Teide Volcano on the Canary Islands of Spain is featured in this image photographed by an Expedition 20 crew member on the International Space Station. This detailed photograph features two stratovolcanoes - Pico de Teide and Pico Viejo - located on Tenerife Island, part of the Canary Islands of Spain.
astro-ph: "We conclude that, as far as we have been exhaustive, we have discovered a planetary companion, named CoRoT-7b, for which we derive a period of 0.853 59 +/- 3 10-5 day and a radius of Rp = 1.68 +/- 0.09 REarth. Analysis of preliminary radial velocity data yields an upper limit of 21 MEarth for the companion mass, supporting the finding. CoRoT-7b is very likely the first Super-Earth with a measured radius."
Astronauts John "Danny" Olivas (foreground) and European Space Agency's (ESA) Christer Fuglesang, both STS-128 mission specialists, use virtual reality hardware in the Space Vehicle Mock-up Facility at NASA's Johnson Space Center to rehearse some of their duties on the upcoming mission to the International Space Station. This type of virtual reality training allows the astronauts to wear a helmet and special gloves while looking at computer displays simulating actual movements around the various locations on the station hardware with which they will be working. high res (1.7 M) low res (101 K)
The Cassini spacecraft looks down on the north pole of Titan, showing night and day in the northern hemisphere of Saturn's largest moon. This view is centered on terrain at 49 degrees north latitude, 243 degrees west longitude. The north pole of Titan is rotated about 23 degrees to the left and it lies on the terminator above and to the left of the center of the image.
