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: August 29, 2014

August 30

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

MAVEN continues on a smooth journey to Mars. All spacecraft systems are operating nominally. Since we are now in a “pre-Mars Orbit Insertion (MOI) moratorium”, all instruments are powered off until after we arrive at the Red Planet.

We had scheduled a final Trajectory Correction Maneuver (TCM-4) for September 12th. The first and second TCMs occurred in December 2013 and February 2014, respectively. The scheduled TCM-3 in July was cancelled because the flight path at the time did not warrant a correction maneuver. As a result of a meeting held on August 26th, it now appears that TCM-4 will also be cancelled. We are tracking right where we want to be. On September 4th we will make a final decision on cancelling this last TCM.
