Getting into orbit is a bit tricky but it worked out well this time:
The spacecraft fired its six main engines at 4:24 p.m. ET and was captured by Mars' gravity. The burn lasted 27 minutes.More details over at CNN.
"Burn baby burn," a team member at NASA's Jet Propulsion Laboratory in California said when the maneuver began.
Twenty-one minutes in, the spacecraft disappeared behind Mars, and was out of radio contact with mission control for a nerve-wracking half-hour.
At 5:16 p.m., the team erupted in cheers when a signal was received back from the craft.
