Pasadena - Mar 09, 2004 - Though the Viking Landers in the 1970s observed the shadow of one Mars' two moons, Phobos, moving across the landscape, and Mars Pathfinder in 1997 observed Phobos emerge at night from the shadow of Mars, no previous mission has ever directly observed a moon pass in front of the sun from the surface of another world.
Moffett Field - Mar 09, 2004 - On the heels of the announcement that the Opportunity site on Mars was 'soaked' in water some time in its distant past, the rover teams have identified candidates for trace water at the Gusev crater site.
Pasadena - Mar 08, 2004 - Like a rabbit in a hat, the identity of an oddity that looks like bunny ears in a picture from Mars has eluded the science and engineering teams. The public, also fascinated with the mysterious object, has asked in a slew of e-mails: What is it?
Pasadena - Mar 05, 2004 - NASA's Spirit has found hints of a water history in a rock at Mars' Gusev Crater, but it is a very different type of rock than those in which NASA's Opportunity found clues to a wet past on the opposite side of the planet.
Moffett Field - Mar 03, 2004 - NASA's Opportunity rover has found convincing evidence that large quantities of water were once present in at least one location on Mars. The rocks here were once soaked in liquid water, said Steve Squyres, principle investigator for the Mars Exploration Rover (MER) mission, referring to the bedrock outcrop near the rover's landing site in Meridiani Planum.
Washington (AFP) Mar 2, 2004 - Water once drenched parts of the planet Mars and conditions may have existed for life as we know it, the US space agency announced Tuesday. NASA associate administrator Ed Weiler told reporters the robotic probe Opportunity has landed in an area of Mars where liquid water once drenched the surface. Moreover, this area would have been a good habitable environment for some period of time.
Washington - Mar 02, 2004 - Scientists have concluded the part of Mars that NASA's Opportunity rover is exploring was soaking wet in the past. Evidence the rover found in a rock outcrop led scientists to the conclusion. Clues from the rocks' composition, such as the presence of sulfates, and the rocks' physical appearance, such as niches where crystals grew, helped make the case for a watery history.
Washington (UPI) Mar 02, 2004 - NASA's $820 million investment in Mars rovers paid off Tuesday as scientists reported the latest data from the Opportunity rover shows liquid water once drenched the surface of the red planet.
Paris (ESA) Mar 01, 2004 - It is the start of eclipse season for Mars Express. That means unavoidable passages of the spacecraft through the shadow of Mars, cutting it off from the sunlight that is converted into electrical power by the orbiter's solar arrays.
Boyertown - Mar 01, 2004 - How many of you would work fifteen hours a day in freezing rain, moving an unwieldy 800 pound piece of metal half a kilometer through mud and rough arctic terrain? And then go back repeatedly to do it all over again? If that appeals to you, then you just might be ready to go to Mars!
Pasadena - Mar 01, 2004 - Dust gradually obscures the Sun during a blue-sky martian sunset seen in a sequence of newly processed frames from NASA's Mars Exploration Rover Opportunity.
Pasadena (JPL) Mar 01, 2004 - Just past the halfway point of its three-month prime mission, NASA's Mars Exploration Rover Spirit has achieved several scientific firsts, but may still have its best Eureka! Moments in front of it.
Pasadena - Mar 01, 2004 - Even before Spirit set foot on martian soil, she was returning stunning images of her new surroundings. And, with her first triumphant roll off the lander, she set out to accomplish lofty science goals. What she left in her wake makes for great bonus science too.
Huntsville - Feb 27, 2004 - When humans go to the moon or Mars, they'll probably take plants with them. NASA-supported researchers are learning how greenhouses work on other planets. Confused? Then you're just like plants in a greenhouse on Mars.
Moffett Field - Feb 25, 2004 - MER engineers at JPL are using a graphical planning tool to plot and scheme the perfect location to place the rock abrasion tool on the rock collection dubbed El Capitan near Opportunity's landing site. El Capitan is located within a larger outcrop nicknamed Opportunity Ledge.
Moffett Field - Feb 25, 2004 - Opportunity has been getting the lion's share of the attention in recent weeks, because its twin sister Spirit has been engaged mostly in long-distance driving. But it may be about to steal the spotlight. For several sols, Spirit has been working its way towards nearby Bonneville crater. But even before it gets there, the mobile robot may make a critical discovery. It may find evidence of liquid water on Mars.
