NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) mission, dedicated to studying the Martian atmosphere for over 11 years, has concluded after experiencing a loss of signal on December 6. The spacecraft was initially launched in November 2013 and completed its primary mission within the first year before continuing its operations for nearly another decade.
A media teleconference is scheduled for 2 p.m. EDT today to discuss MAVEN’s achievements. In February, NASA convened an anomaly review board which concluded that MAVEN is not recoverable and can no longer perform its scientific and data relay missions. This aligns with findings from the mission team.
Prior to the December signal loss, telemetry indicated all subsystems were functioning normally. However, upon re-emergence from behind Mars, no signal was detected from MAVEN. Preliminary analysis of recorded radio signals indicated that the spacecraft entered a safe mode and was rotating at a high rate, leading to drained batteries and a loss of communication capabilities.
The specific cause of this anomaly is still being investigated, and a final report from the review board is expected later this year. NASA is beginning the decommissioning process for MAVEN, which includes archiving its mission dataset.
Insights gained from MAVEN will continue to inform future missions, particularly in preparing for human exploration of Mars, according to Louise Prockter, director of the Planetary Science Division at NASA Headquarters. MAVEN’s 11 years of data collection has provided critical information regarding the Martian atmosphere, climate, and habitability.
Major discoveries from MAVEN’s mission include the impact of solar storms on atmospheric loss, the identification of various types of auroras on Mars, and observations of atmospheric sputtering. MAVEN was also involved in studying the effects of global dust storms on the Martian atmosphere.
Additionally, MAVEN supported the observation of comet 3I/ATLAS, capturing high-resolution images to analyze the comet’s composition. Throughout its mission, the MAVEN science team produced over 800 publications, with more anticipated.
MAVEN also played a crucial role in NASA’s Mars Relay Network, facilitating data communication from Mars rovers to Earth, and set a record for the most data relayed from another planet in a single day.
Participants in today’s media teleconference will include leaders from various NASA divisions involved with the MAVEN mission.
