2.The orbiter will continue to explore Saturn and its moons for four more year.
3.The team proposed the theory after studying data from the Thermal Emission Imaging System on the Mars Odyssey orbiter.
5.In September 1999 its Mars Climate Orbiter was lost as a failed rocket burn plunged it into the Martian atmosphere.
6.To let this happen, the orbiter fired thruster enginers to slow its nearly 18,000 kilometer per hour speed by one-third.
7.Over the last year three teams, one using instruments on the Mars Express orbiter and two using ground-based telescopes, say they have detected methane in the Martian atmosphere.
8.Plans for the coming days include attempts to capture images of the errant spacecraft from Mars Reconnaissance Orbiter and to communicate with it using the Mars Exploration Rovers.
9.The most sophisticated robotic spacecraft ever built, the Cassini orbiter and the attached Huygens probe, were poised atop the launch vehicle, and seven years of interplanetary voyaging lay ahead.
10.The NASA budget announced in February mows down a scarily long list of science missions, from a Europa orbiter to a space-based gravitational-wave observatory.
