MAVEN team at Goddard Space Flight Center for Critical Design Review

The MAVEN team at the Critical Design Review in July 2011. Several hundred additional scientists, engineers, and support personnel are contributing to the success of MAVEN, but were not present at the review. (Courtesy MAVEN)


The MAVEN team includes experts from many institutions and disciplines. The team blog is a forum for these individuals to share their personal experiences with the MAVEN community. From exploring the science of the mission, to the engineering behind the instrumentation, from the complex aspects of project management, to the access and use of data products, we hope you enjoy the opportunity to engage with the MAVEN team through these anecdotes.

MAVEN Status Update: Sept. 21, 2014

September 21

Everything is set for MAVEN’s arrival at Mars tonight. All spacecraft systems are operating nominally. MAVEN is right on track without the need for any further trajectory correction maneuvers.

Tonight MAVEN will slew (turn) to point the main engines in the direction of travel and fire for about 33 minutes in order to slow down the spacecraft enough to “capture” into Mars orbit. Although we have direct line of sight of MAVEN during the entire burn sequence, the observed data back on Earth will actually be viewed 12.5 minutes after the events occur because of the distance between Earth and Mars.

MAVEN Status Update: Sept. 15, 2014

September 15

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

Everything continues to go well with MAVEN as it is readied for arrival at Mars on Sunday, September 21st. All spacecraft systems are operating nominally. We had scheduled a final Trajectory Correction Maneuver (TCM-4) for September 12th. However, the maneuver was cancelled because the flight path did not warrant a correction. MAVEN is right on track.

In the next few days the Mars Orbit Insertion (MOI) sequence will commence on the spacecraft. Most commands will be performed autonomously (without the need for commanding from Earth). However, there are two ground command opportunities still available to alter the spacecraft’s flight path, if necessary, in order to raise altitude for its first pass at Mars. These altitude raise decisions will be made by the Project at approximately 24 hours and 6 hours prior to MOI, in close coordination with the Navigation team and the Navigation Advisory Group. Right now we don’t expect to need an additional maneuver because of how well the spacecraft is flying.

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.

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.

MAVEN Particles and Fields: Exploring the Solar Wind Beyond 1 A.U.

July 2

As part of its goal to explore Mars’ upper atmosphere and its interaction with the sun and the solar wind, MAVEN is exploring propagation of the solar wind and solar energetic particles (SEPs) beyond 1 Astronomical Unit (149,597,871 kilometers or 92,955,807 miles) during its cruise to Mars.
