10.02.08 - NASA is developing technologies that will allow lunar landers to automatically identify and navigate to the location of a safe landing site while detecting landing hazards during the final descent to the surface.
10.02.08 - Scientists using NASA’s RHESSI spacecraft have measured the roundness of the sun with unprecedented precision and found that it is not a perfect sphere.
10.01.08 - Hot spots near the shattered remains of an exploded star are echoing the blast's first moments, say scientists using data from NASA's Spitzer Space Telescope.
09.30.08 - There's an old saying in astronomy: Galaxies are like people. They're only normal until you get to know them.
09.29.08 - NASA's Phoenix Mars Lander has detected snow falling from Martian clouds. Spacecraft soil experiments also have provided evidence of past interaction between minerals and liquid water, processes that occur on Earth.
09.29.08 - Scientists find that dim areas at the edges of active sunpot regions may hold the key to the sun's energy processes.
09.25.08 - One of the nearest supernovas in the last 25 years has been identified over a decade after it exploded.
09.26.08 - NASA data are showing that for a four-week period in August 2008, sea ice melted faster during that period than ever before.
09.24.08 - Tons, perhaps tens of tons, of carbon molecules in dust particles and meteorites fall on Earth daily. Researchers have noticed that most meteorite carbon are polycyclic aromatic hydrocarbons, the most common carbon-rich compound in the universe.
09.23.08 - Despite a moderate summer, the heat is rising in Southern California.
09.22.08 - NASA's Mars Rover Opportunity is setting its sights on a crater more than 20 times larger than its home for the past two years.
09.22.08 - Project scientist Gerry Soffen called Israel Taback the "father of the Mars Viking Lander," parentage that Taback rejected with his usual wry wit. "It didn't need a father. More of a godfather."
09.19.08 - NASA's Swift satellite has found the most distant gamma-ray burst ever detected. The blast arose from a star 12.8 billion light-years away.
09.17.08 - A new color high-resolution image from the Phoenix Mars Lander shows its crumpled heat shield about 150 meters away from the spacecraft.
09.15.08 - NASA has selected a Mars robotic mission that will provide information about the Red Planet's atmosphere, climate history and potential habitability in greater detail than ever before.
09.16.08 - Arctic sea ice coverage appears to have reached its lowest extent for 2008 and the second-lowest amount recorded since the dawn of the satellite era.
9.17.08 - When it comes to firing telescopes and their instruments into the frigid cold of space, the more you test your hardware, the better.
09.16.08 - These Hubble images offer an unprecedented view of a planetary game of Pac-Man among three red spots clustered together in Jupiter's atmosphere.

09.11.08 - Phoenix has photographed several dust devils dancing across the arctic plain this week and sensed a dip in air pressure as one passed near the lander.
