MAVEN is on the way to Mars

A picture-perfect launch on an Atlas V rocket has sent MAVEN on her way to Mars. Two weeks ago, a rocket leapt off the launch pad to take India's Mars Orbiter Mission aloft. By comparison, today's launch seemed to take place in slow motion. Here's a replay:

Following the two-stage burn of Atlas and Centaur, the spacecraft coasted for about half an hour before Centaur fired again to place MAVEN on a direct-to-Mars trajectory. After separating from the Centaur, MAVEN quickly established contact with Earth through her low-gain antenna. A few minutes later, the solar panels deployed and started charging her batteries, and she was truly on her own and on her way to Mars.

Shortly after MAVEN launched to Mars on November 18, 2013, its signal was picked up by two 34-meter Deep Space Network antennae in Australia: DSS-34, at center, and DSS-45, at right. Meanwhile, the 70-meter dish, DSS-43 (left), tracked Mars Odyssey and Mars Reconnaissance Orbiter.

Over the next three months, mission controllers will test out spacecraft systems and scientific instruments, culminating in the first use of the high-gain antenna. According to MAVEN's Twitter feed, today's on-time launch puts the mission on course for a September 22, 2014 arrival at Mars. The first trajectory correction maneuver will take place in two weeks, on December 3.
