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.
09.08.08 - The recent flurry of tropical cyclones in the Atlantic is a reminder that we are now entering the peak of the Atlantic hurricane season, and this season is turning out to be well above average.
09.05.08 - Cassini has detected a faint, partial ring orbiting with one small moon of Saturn, and has confirmed the presence of another partial ring orbiting with a second moon.
09.04.08 - A fork-like conductivity probe has sensed humidity rising and falling beside Phoenix, but when stuck into the ground, its measurements so far indicate soil that is thoroughly and perplexingly dry.
09.03.08 - NASA's 50th anniversary was celebrated with an all-star gathering of legendary American astronauts.
08.26.08 - NASA's Mars Exploration rover Opportunity is heading back out to the Red Planet's surrounding plains nearly a year after descending into a large Martian crater to examine exposed ancient rock layers.
08.25.08 - The next sample of Martian soil being grabbed for analysis is coming from a trench about three times deeper than any other trench NASA's Phoenix Mars Lander has dug.
08.22.08 - The booster carrying NASA's Hypersonic Boundary Layer Transition (HYBOLT) and Sub-Orbital Aerodynamic Re-entry Experiments (SOAREX) had to be destroyed shortly after liftoff Aug. 22.
› Mission Overview08.18.08 - A new analysis of environmental conditions over the Atlantic Ocean shows that hot, dry air associated with dust outbreaks from the Sahara desert likely contributed to the quieter-than-expected 2007 hurricane season.
08.14.08 - Researchers have identified the common thread that determines how aerosols from human activity, like the particles released from forest fires, influence cloud cover and affect climate.
