Mars Atmosphere and Volatile EvolutioN Mission
MAVEN Status Update: Feb. 27, 2014
On Feb. 26, MAVEN mission controllers at Lockheed Martin 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.
Upcoming events in March include continuing calibrations and checkouts
of various instrument and spacecraft systems. 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.
