MAVEN Status Update: Oct. 15, 2014
Commissioning activities have gone extremely well over the few weeks since MAVEN entered Mars orbit on September 21. Since then, we have successfully completed four engine burns to lower MAVEN’s orbit. MAVEN now orbits Mars every 4.6 hours with a periapsis (closest distance from the Mars surface) of 175 kilometers. All instruments are activated, and we are seeing data that represents exciting first science from the Mars upper atmosphere. Just yesterday the science team held a telephone conference call with the media to discuss early results.
MAVEN: Mars Atmosphere and Volatile EvolutioN
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.
