US - NASA craft settles into Mars orbit

The AP reports.

PASADENA, Calif. - The most powerful spacecraft ever sent to Mars has settled into a nearly circular orbit, a move that allows scientists to begin studying the planet in unprecedented detail, NASA said Tuesday.

The Mars Reconnaissance Orbiter fired its thrusters for 12 minutes Monday to adjust to its final position six months after it arrived at the planet. Its altitude ranges between 155 to 196 miles above the surface.

"Getting to this point is a great achievement," said Dan Johnston, deputy mission manager at the space agency's Jet Propulsion Laboratory, which manages the $720 million mission.

Over the next several months, the orbiter will deploy its 33-foot antenna and remove a lens cap from one of its instruments. It will begin collecting data in November, and scientists expect the resolution of those images to be nine times higher.
