Submission + - Mars Phoenix Spacecraft Corrects Course (space.com)
Raver32 writes: "NASA's Mars-bound Phoenix lander completed its first and biggest course correction planned during the spacecraft's journey.
The second of the remaining five planned adjustments prior to landing is scheduled for mid-October.
"These first two together take out the bias intentionally put in at launch," said Brian Portock, Phoenix navigation team chief at NASA's Jet Propulsion Laboratory.
Phoenix blasted off Earth aboard a Delta 2 rocket on Aug. 4 and now careens through space at 74,200 mph (33,180 meters per second)-a speed necessary to cover the 422 millions miles (679 million kilometers) between Earth and Mars by May 25, 2008."
