MAVEN Status Update: July 31, 2014
MAVEN continues on a smooth journey to Mars. All spacecraft and instrument systems are operating nominally. This month was a busy time for spacecraft operations. We performed a series of tests on the Electra telecom relay package, some of the Particles & Fields instruments from the University of California-Berkeley, the mass spectrometer from the Goddard Space Flight Center, and the spacecraft star trackers. The team also did a second round of magnetometer calibrations. The Goddard-built magnetometers are located at the tips of the spacecraft solar arrays. The calibration was conducted by rolling the spacecraft, using thrusters, about the three spacecraft axes.

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.
