(PhysOrg.com) -- NASA's Mars Rover Opportunity is investigating a metallic meteorite the size of a large watermelon that is providing researchers more details about the Red Planet's environmental history. http://www.physorg.com/news169145414.html Space & Earth Mon, 10 Aug 2009 17:50:41 EST news169145414 (PhysOrg.com) -- Composition measurements by NASA's Mars Exploration Rover Opportunity confirm that this rock on the Martian surface is an iron-nickel meteorite. http://www.physorg.com/news168801850.html Space & Earth Thu, 06 Aug 2009 18:24:44 EST news168801850 (PhysOrg.com) -- The Opportunity rover has eyed an odd-shaped, dark rock, about 0.6 meters (2 feet) across on the surface of Mars, which may be a meteorite. http://www.physorg.com/news168534413.html Space & Earth Mon, 03 Aug 2009 16:30:02 EST news168534413 In one of the most remarkable engineering feats of our time, the aging Mars rovers Spirit and Opportunity are still taking orders and sending home pictures more than five years after they were supposed to turn into slabs of space junk. http://www.physorg.com/news165402360.html Space & Earth Sun, 28 Jun 2009 10:06:33 EST news165402360 (PhysOrg.com) -- One of NASA's two Mars rovers has recorded a compelling saga of environmental changes that occurred over billions of years at a Martian crater. http://www.physorg.com/news162139346.html Space & Earth Thu, 21 May 2009 15:43:39 EST news162139346 In January 2004, NASA landed two identical robotic rovers named Spirit and Opportunity on the surface of Mars. The twins were primed for a brief 3-month mission to tell us a story of water and possibly life itself in the planet's past. More than five years later, the dynamic duo are still roving the Red Planet, engaged in a saga of overachievement that has transformed Mars exploration. http://www.physorg.com/news157305969.html Space & Earth Thu, 26 Mar 2009 17:06:52 EST news157305969 (PhysOrg.com) -- On a plain that stretches for miles in every direction, the panoramic camera on NASA's Mars rover Opportunity has caught a first glimpse on the horizon of the uplifted rim of the big crater that has been Opportunity's long-term destination for six months. http://www.physorg.com/news156621141.html Space & Earth Wed, 18 Mar 2009 18:54:50 EST news156621141 (PhysOrg.com) -- NASA rovers Spirit and Opportunity may still have big achievements ahead as they approach the fifth anniversaries of their memorable landings on Mars. http://www.physorg.com/news149872296.html Space & Earth Tue, 30 Dec 2008 15:11:36 EST news149872296 (PhysOrg.com) -- The Mars rover Opportunity, which has just crawled out of the 800-meter-wide (875 yards) Victoria Crater is setting out on the longest journey of its life. It will take the rover roughly two years of driving at its top speed -- up to 100 meters (109 yards) a day -- to reach its new target, a crater 20 times the size of Victoria that the Mars Exploration Rover team has unofficially dubbed "Endeavour." http://www.physorg.com/news141576125.html Space & Earth Thu, 25 Sep 2008 15:42:05 EST news141576125 (PhysOrg.com) -- 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. http://www.physorg.com/news141318410.html Space & Earth Mon, 22 Sep 2008 16:06:50 EST news141318410 (PhysOrg.com) -- NASA's Mars Exploration Rover Opportunity has climbed out of the large crater that it had been examining from the inside since last September. http://www.physorg.com/news139496555.html Space & Earth Mon, 01 Sep 2008 14:02:35 EST news139496555 (PhysOrg.com) -- 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. http://www.physorg.com/news138985571.html Space & Earth Tue, 26 Aug 2008 16:06:11 EST news138985571
