Almost 40 years ago, NASA's Mariner 9 spacecraft relayed to Earth the first video images of Mars' northern polar ice cap, revealing a strange pattern of spiral swirls that has puzzled scientists ever since. Using new data from the Mars Reconnaissance Orbiter (MRO), researchers have finally uncovered the secrets of the troughs that snake through the ice cap like a spiraled maze. Jack Holt of the University of Texas and his graduate student Isaac Smith used radar data from MRO's Shallow...

From May 17 to 21, NASA's Mars Odyssey orbiter will conduct a fourth and final campaign to check on whether the Phoenix Mars Lander has come back to life. During that period, Odyssey will listen for a signal from Phoenix during 61 flights over the lander's site on far-northern Mars. The orbiter detected no transmission from the lander in earlier campaigns totaling 150 overflights in January, February and April. In 2008, Phoenix completed its three-month mission studying Martian ice, soil and...

NASA's Mars Odyssey orbiter heard no signal from the Phoenix Mars Lander when it listened from orbit while passing over Phoenix 60 times last week. Odyssey had also listened for a signal from Phoenix during periods in January and February. During the third campaign, April 5 through April 9, the sun stayed above the horizon continuously at the arctic site where Phoenix completed its mission in 2008. The solar-powered lander examined ice, soil and atmosphere at the site for two months longer...

NASA's Phoenix Mars Lander showed no sign during February that it has revived itself after the northern Mars winter. NASA's Mars Odyssey orbiter will check again in early April. The solar-powered Phoenix lander operated for two months longer than its planned three-month mission in the Martian arctic in 2008. It was not designed to withstand winter conditions. However, in case the return of abundant springtime sunlight to the site does revive Phoenix, Odyssey is conducting three periods of...
