(PhysOrg.com) -- NASA's Dawn spacecraft re-entered our solar system's asteroid belt today, Nov. 13, and this time it will stay there. http://www.physorg.com/news177615422.html Space & Earth Mon, 16 Nov 2009 18:30:02 EST news177615422 Astronomer and long time science advocate Carl Sagan once said that he was "not very good at singing songs." But on Nov. 9 in Washington D.C., his voice could be heard singing about the wonders of universe -- 13 years after his death. http://www.physorg.com/news177269555.html Other Sciences Thu, 12 Nov 2009 17:33:02 EST news177269555 As the flames of the raging brush fire dubbed the Station Fire threatened the northern edge of NASA's Jet Propulsion Laboratory on Saturday, Aug. 29, the managers of NASA's Deep Space Network prepared for the worst. http://www.physorg.com/news171820880.html Space & Earth Thu, 10 Sep 2009 17:03:10 EST news171820880 (PhysOrg.com) -- With Mars disappearing in its metaphorical rearview mirror, NASA's Dawn spacecraft's next stop is the asteroid belt and the giant asteroid Vesta. Dawn got as close as 549 kilometers (341 miles) to the Red Planet during its Tuesday, Feb. 17, flyby. http://www.physorg.com/news154966600.html Space & Earth Fri, 27 Feb 2009 14:17:33 EST news154966600 (PhysOrg.com) -- Launched in September of 2007, and propelled by any one of a trio of hyper-efficient ion engines, NASA's Dawn spacecraft passed the orbit of Mars last summer. At that time, the asteroid belt (where Dawn's two targets, asteroid Vesta and the dwarf planet Ceres reside), had never been closer. In early July the spacecraft began to lose altitude, falling back towards the inner solar system. Then on October 31, 2008, after 270 days of almost continuous thrusting, the ion drive turned off. http://www.physorg.com/news153759402.html Space & Earth Fri, 13 Feb 2009 14:57:28 EST news153759402 (PhysOrg.com) -- The images, produced by scientists at Durham University's Institute for Computational Cosmology, show the "Cosmic Dawn" - the formation of the first big galaxies in the Universe. http://www.physorg.com/news153549252.html Space & Earth Wed, 11 Feb 2009 04:34:50 EST news153549252 (PhysOrg.com) -- NASA's Dawn spacecraft shut down its ion propulsion system today as scheduled. The spacecraft is now gliding toward a Mars flyby in February of next year. http://www.physorg.com/news146495840.html Space & Earth Fri, 21 Nov 2008 13:17:20 EST news146495840 What does Jack LaLanne have in common with a Jamaican lizard? Like the ageless fitness guru, the lizards greet each new day with vigorous push-ups. That's according to a new study showing that male Anolis lizards engage in impressive displays of reptilian strength -- push-ups, head bobs, and threatening extension of a colorful neck flap called a dewlap -- to defend their territory at dawn and dusk. http://www.physorg.com/news139060816.html Biology Wed, 27 Aug 2008 13:00:16 EST news139060816
