Astronomers Probe Mysterious Gas In Titan's Atmosphere

Posted by samzenpus on Wednesday March 13, 2013 @11:36AM from the up-in-the-air dept.

sciencehabit writes "A fluorescent glow high in the atmosphere of Titan, Saturn's largest moon, signifies the presence of a gas that astronomers have yet to identify. The glow appears only on the daytime side of the moon at altitudes between 600 and 1250 kilometers, with the largest intensity occurring at an altitude of about 950 km. Detailed analyses reveal that the glow doesn't stem from a problem with the Saturn-orbiting Cassini craft, and it isn't associated with methane or any of the other hydrocarbons already identified as constituents of Titan's atmosphere."

Considering that Cassini is a WORKING orbiter around Saturn, a thing we are unlikely to see again in most of our lifetimes, I'm good with them funding the use of it as long as it keeps running, for no other reason than to keep looking for things it missed the first (or hundredth) time around. Same for any other working interplanetary spacecraft. If (and only if) someone can make the case that defunding Cassini will directly free up funding for the next probe to Saturn, then maybe, but I don't believe that will happen.
