MRO Enters Mars Orbit, Will Search for Future Landing Sites

摘要

After seven months of interplanetary spaceflight, NASA's Mars Reconnaissance Orbiter (MRO) successfully reached the red planet March 10 to take an in-depth look at the dusty world. The $450 million spacecraft, aimed at tracking Mars' watery past and hunting for landing sites to aid future missions, entered orbit at about 4:24 p.m. EST March 10, after firing six main engines to slow itself from an, 17,702 kilometer-per-hour gait.
