It wasn't easy, though. Controllers expected to get the spacecraft orienting on its target star within a few days, but it took weeks because sunlight reflecting off of dust particles confused its tracking system. Engineers also had to tweak the spacecraft's software to compensate for cosmic rays that flashed into its telescope. Everything's working fine now, and in a year or so, we should have some answers. http://www.universetoday.com/am/publish/gravity_probe_b_ready_tough.html <a href="http://www.universetoday.com/am/publish/gravity_probe_b_ready_tough.html";>AOL Link</a> ENVISAT WATCHES HURRICANE FRANCES Sep 3, 2004 - The European Space Agency's Envisat Earth has a whole suite of tools to analyze Hurricane Frances with, and that's just what it's done. The Earth observation satellite has both optical and radar instruments, and it can observe high-atmosphere cloud structure in both the visible and infrared spectrum, and use radar backscatter to look at the roughness of the water underneath to calculate wind speeds. Frances is expected to make landfall in Florida on Saturday and cause a significant amount of damage. http://www.universetoday.com/am/publish/envisat_watches_hurricane_frances.html <a href="http://www.universetoday.com/am/publish/envisat_watches_hurricane_frances.html";>AOL Link</a> SATURN'S COOL... WELL, ITS RINGS ARE Sep 2, 2004 - According to NASA's Cassini spacecraft, the temperature of Saturn's rings range from cold to really really cold. In this false-colour image, the red signifies 110 Kelvin (-261 degrees F), and the blue is 70 Kelvin (-333 degrees F). Cassini has shown that opaque regions of the rings are cooler, while transparent sections are warmer; this was predicted by scientists before the spacecraft arrived. The data was gathered using one of Cassini's 12 scientific instruments, the composite infrared spectrometer. http://www.universetoday.com/am/publish/cool_saturn_rings.html <a href="http://www.universetoday.com/am/publish/cool_saturn_rings.html";>AOL Link</a> Additional headlines from Universe Today http://www.universetoday.com/am/exec/search.cgi?start=5&perpage=8&template=index/default.html <a href="http://www.universetoday.com/am/exec/search.cgi?start=4&perpage=8&template=index/default.html";>AOL Link</a> All contents copyright (c) 2004 Universe Today ----------------------------------------------------- -- To unsubscribe from: Universe Today - Daily Edition (Text), just follow this link: http://www.universetoday.com/mojo/mojo.cgi?f=u&l=ut%2dtext&[EMAIL PROTECTED]&p=4996766 Click this link, or copy and paste the address into your browser.
