05.22.08 - I keep getting asked about whether Phoenix will find life on Mars, so I've thought quite a bit about what Phoenix is and is not doing.
05.20.08 - I keep getting asked about whether Phoenix will find life on Mars, so I've thought quite a bit about what Phoenix is and is not doing.
05.16.08 - Phoenix successfully performed a maneuver on May 17 to adjust its course slightly toward the center of the approved landing area.
05.15.08 - New observations from NASA's Mars Reconnaissance Orbiter indicate that the crust and upper mantle of Mars are stiffer and colder than previously thought.
05.16.08 - NASA news briefings, live commentary and updates before and after the scheduled Sunday, May 25 arrival of the agency's Phoenix Mars Lander will be available on NASA Television and on the Web.
05.14.08 - This is a list of events around and during the Phoenix landing on Mars.
05.13.08 - NASA's Phoenix Mars Lander is preparing to end its long journey and begin a three-month mission to taste and sniff fistfuls of Martian soil and buried ice.
05.09.08 - NASA's Phoenix Mars Lander continues on course for its May 25 arrival at Mars.
04.23.08 - A small motor in the robotic arm of NASA's Mars Exploration Rover Opportunity that began stalling occasionally more than two years ago has become more troublesome recently.
04.10.08 - NASA engineers have adjusted the flight path of the Phoenix Mars Lander, setting the spacecraft on course for its May 25 landing on the Red Planet.
04.09.08 - A new stereo view of Phobos, the larger and inner of Mars' two tiny moons, has been captured by a NASA spacecraft orbiting Mars.
03.31.08 - High school students in three states are working with Mars researchers on observations for an instrument on NASA's Mars Reconnaissance Orbiter.
03.20.08 - NASA's Mars Odyssey orbiter has found evidence of salt deposits.
03.03.08 - A NASA spacecraft in orbit around Mars has taken the first ever image of active avalanches near the Red Planet's north pole.
02.28.08 - Three Mars spacecraft are adjusting their orbits to be over the right place at the right time to listen to NASA's Phoenix lander as it enters the Martian atmosphere on May 25.
02.15.08 - Like salt used as a preservative, high concentrations of dissolved minerals in the wet, early-Mars environment known from discoveries by NASA's Opportunity rover may have thwarted any microbes from developing or surviving.
01.23.08 - Mars has an ethereal, tenuous atmosphere with less than one-percent the surface pressure of Earth, which challenges scientists to explain complex, wind-sculpted landforms seen with unprecedented detail in images from NASA's Mars Reconnaissance Orbiter.
12.21.07 - As expected, scientists at JPL's Near-Earth Object Office have further refined the trajectory estimate for asteroid 2007 WD5 and ruled out any possibility of a Mars impact on Jan. 30.
12.11.07 - Scrutiny by NASA's newest Mars orbiter is helping scientists learn the stories of some of the weirdest landscapes on Mars, as well as more familiar-looking parts of the Red Planet.
11.13.07 - The flight team for NASA's Mars Reconnaissance Orbiter has put the spacecraft back into operations. Science instruments have been powered up, and observations of Mars have resumed.
