Living microbes might have even arisen, some scientists believe, starting Mars down the path toward becoming a second life-filled planet next door to our own. http://www.physorg.com/news177179617.html Space & Earth - Space Exploration Wed, 11 Nov 2009 16:34:12 EST news177179617 Sunspots, which rotate around the sun's surface, tell us a great deal about our own planet. Scientists rely on them, for instance, to measure the sun's rotation or to prepare long-range forecasts of the Earth's health. http://www.physorg.com/news177169609.html Space & Earth - Space Exploration Wed, 11 Nov 2009 14:50:01 EST news177169609 The Sun is a bubbling mass. Packages of gas rise and sink, lending the sun its grainy surface structure, its granulation. Dark spots appear and disappear, clouds of matter dart up - and behind the whole thing are the magnetic fields, the engines of it all. The SUNRISE balloon-borne telescope, a collaborative project between the Max Planck Institute for Solar System Research in Katlenburg-Lindau and partners in Germany, Spain and the USA, has now delivered images that show the complex interplay on the solar surface to a level of detail never before achieved. http://www.physorg.com/news177164239.html Space & Earth - Space Exploration Wed, 11 Nov 2009 12:17:58 EST news177164239 This year's Leonid meteor shower peaks on Tuesday, Nov. 17th. If forecasters are correct, the shower should produce a mild but pretty sprinkling of meteors over North America followed by a more intense outburst over Asia. The phase of the Moon will be new, setting the stage for what could be one of the best Leonid showers in years. http://www.physorg.com/news177093817.html Space & Earth - Space Exploration Tue, 10 Nov 2009 16:46:47 EST news177093817 The Voyager spacecraft are now in the outermost layer of the heliosphere, traveling toward interstellar space - the first man-made spacecraft to travel such a vast distance from Earth. http://www.physorg.com/news177092513.html Space & Earth - Space Exploration Tue, 10 Nov 2009 16:40:01 EST news177092513 A Soyuz rocket carrying a new Russian-made module for the International Space Station blasted off on Tuesday from the Baikonur space base in Kazakhstan, television pictures showed. http://www.physorg.com/news177083298.html Space & Earth - Space Exploration Tue, 10 Nov 2009 13:49:54 EST news177083298 (AP) -- Four years after its first solar sail ended up in the ocean instead of orbit, The Planetary Society announced Monday that by the end of 2010 it will try again to launch a spacecraft that will be propelled by the subtle pressure of sunlight. http://www.physorg.com/news177020675.html Space & Earth - Space Exploration Mon, 09 Nov 2009 21:00:01 EST news177020675 (AP) -- A Seattle team has collected a $900,000 prize in a NASA-backed competition to develop the concept of an elevator to space - an idea spurred by science fiction novels. http://www.physorg.com/news176809468.html Space & Earth - Space Exploration Sat, 07 Nov 2009 09:45:52 EST news176809468 The station crew prepared Friday for the arrival of the Russian Mini-Research Module 2 (MRM2) which is scheduled for launch from the Baikonur Cosmodrome, Kazakhstan on Nov. 10.

The stratospheric dust includes minute grains that likely formed inside stars that lived and died long before the birth of our sun, as well as material from molecular clouds in interstellar space. This "ultra-primitive" material likely wafted into the atmosphere after the Earth passed through the trail of an Earth-crossing comet in 2003, giving scientists a rare opportunity to study cometary dust in the laboratory. http://www.physorg.com/news176400764.html Space & Earth - Space Exploration Mon, 02 Nov 2009 17:00:02 EST news176400764
