NASA is investigating whether incorrect software commands may have doomed the Mars Global Surveyor spacecraft, which abruptly fell silent in November after a decade of meticulously mapping the Red Planet. The space agency said that theory was one of several that might explain the failure of the probe, the oldest of six craft exploring Mars.

Catching a break with the Florida weather Friday afternoon, the space shuttle Discovery made a perfect sunset landing at Kennedy Space Center at 5:32 p.m. EST. Mission controllers had waved off an earlier landing opportunity because of storms and low clouds, but the weather unexpectedly cleared enough to allow the attempt.

Thick clouds over the launch site in central Florida forced the cancellation of Thursday's scheduled launch of the space shuttle Discovery. NASA flight controllers at Kennedy Space Center kept the crew strapped into their seats until the launch window officially closed at 9:36 p.m. EST in the hope that the weather might improve. In the end, however, weather violated two flight regulations, one for the heavy clouds and a second one for the low cloud ceiling.

NASA wrestled with two late-breaking technical concerns that showed up Tuesday, two days before the scheduled launch of space shuttle Discovery, but managers weren't sure whether they would delay the start of the mission. The launch still was scheduled for Thursday night.

NASA officials gave the go-ahead Wednesday for a Dec. 7 launch of the space shuttle Discovery -- the first night launch since NASA resumed shuttle flights after the loss of Columbia in 2003. The last three shuttle missions launched in daylight so newly installed cameras on the ground and aboard the shuttle could get the best possible views of any debris loss during liftoff. Columbia was damaged during launch by a piece of insulating foam that flaked off its giant external fuel tank.

After two weeks of futilely searching for the Mars Global Surveyor, NASA and Jet Propulsion Laboratory officials said Tuesday that the missing spacecraft was probably lost forever. In its 10-year career, the probe has sent back more than 240,000 images of the red planet, providing the first strong evidence that water flowed there as recently as 100,000 years ago. It also charted weather cycles and mapped landing sites for the two rovers now operating on the Martian surface.

A federal probe of NASA Inspector General Robert Cobb outlines allegations that he stifled investigations, mistreated department employees and maintained a close personal relationship with top officials of the agency he was supposed to independently monitor, according to a confidential summary of the findings obtained by the Orlando Sentinel in Florida.

NASA Administrator Michael D. Griffin gave the go-ahead for a repair mission to the Hubble Space Telescope on Tuesday, declaring the goal of saving one of the space agency's most popular science missions to be worth the risk of a shuttle flight. The mission would launch as early as May 2008, carrying new cameras, batteries and gyroscopes. Hubble is operating on only two of six gyroscopes and battery power is running down.

Twin spacecraft blasted off on a mission to study huge eruptions from the sun that can damage satellites, disrupt electrical and communications systems on Earth, and endanger spacewalking astronauts. The two NASA spacecraft, known as STEREO, for Solar Terrestrial Relations Observatory, lifted off Wednesday from Cape Canaveral in Florida, aboard a Delta II rocket.

LAS CRUCES, N.M. -- An attempt by video game designer-turned-rocketeer John Carmack to claim a NASA prize for designing a next-generation lunar lander ended in flames Saturday when Carmack's experimental craft crashed in the New Mexican desert. The liquid-oxygen-ethanol-powered craft plunged into the desert just after liftoff on the second leg of its flight, starting a small fire that was quickly doused, officials said.
