MAVEN Status Update: Feb. 27, 2014
On Feb. 26, mission controllers performed a successful second trajectory correction maneuver, also known as TCM-2. Post-maneuver data review shows that TCM-2 went according to plan. This burn lasted approximately 19 seconds and imparted a change in velocity of 68.8 centimeters per second (1.54 mph). The maneuver was used to adjust the "aim point" of MAVEN at its closest approach when it arrives at Mars, so that it can properly enter orbit around the planet. All spacecraft systems continue to show nominal performance. TCM-1 occurred on Dec. 3, 2013. TCM-3 is scheduled for July 23.
MAVEN is at a distance of 21.2 million kilometers (13.2 million miles) from Earth and 103.7 million kilometers (64.4 million miles) from Mars. The current velocity is 29.44 kilometers per second (65,855 mph) as it moves around the sun.
MAVEN's principal investigator is based at the University of Colorado Boulder's Laboratory for Atmospheric and Space Physics in Boulder, Colo. The university provided science instruments and leads science operations, as well as education and public outreach, for the mission. NASA's Goddard Space Flight Center in Greenbelt, Md., manages the project and provided two of the science instruments for the mission. Lockheed Martin Space Systems in Denver built the spacecraft and is responsible for mission operations. The University of California at Berkeley's Space Sciences Laboratory provided science instruments for the mission. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, Calif., provides navigation support and Deep Space Network support, in addition to the Electra hardware and operations.

Answers About Mars Climate History
The Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, scheduled for launch in late 2013, will be the first mission devoted to understanding the Martian upper atmosphere.
The goal of MAVEN is to determine the role that loss of atmospheric gas to space played in changing the Martian climate through time. Where did the atmosphere – and the water – go?
- MAVEN will determine how much of the Martian atmosphere has been lost over time by measuring the current rate of escape to space and gathering enough information about the relevant processes to allow extrapolation backward in time.
