The Mars Atmosphere and Volatile Evolution mission (MAVEN) launched on November 18, 2013, and is on track to arrive at Mars on September 21, 2014. The mission’s goal is to explore the planet’s upper atmosphere, ionosphere, and interactions with the Sun and solar wind. Scientists will use MAVEN data to explore the loss of volatile compounds—such as CO2, N2, and H2O—from the Martian atmosphere to space. Understanding atmospheric loss will give scientists insight into the history of Mars' atmosphere and climate, liquid water, and planetary habitability.

MAVEN Status Update: July 31, 2014

July 31

David F. Mitchell, MAVEN Project Manager at NASA’s Goddard Space Flight Center

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.
