NASA announced the official end of the MAVEN spacecraft mission on June 3, 2026 [4].
The decommissioning of the Mars Atmosphere and Volatile Evolution orbiter marks the conclusion of a decade of research into how Mars lost its atmosphere. This data helps scientists understand the planet's transition from a potentially habitable world to a frozen desert.
The spacecraft had been orbiting Mars since 2014 [1]. Over a mission that lasted more than 10 years [2], MAVEN provided critical insights into the solar wind and the erosion of the Martian atmosphere.
NASA lost contact with the orbiter on Dec. 6, 2025 [3]. Data received prior to the silence indicated the spacecraft was spinning unexpectedly. This instability threatened the trajectory of the probe and the life of its batteries, eventually prompting the agency to retire the mission [3].
The loss of the orbiter comes after years of success in mapping the volatile evolution of the planet. While the spacecraft is no longer operational, the archives of its findings remain available for the global scientific community to analyze.
NASA said the mission is now officially closed following the prolonged period of silence from the spacecraft.
“NASA announced the official end of the MAVEN spacecraft mission on June 3, 2026.”
The retirement of MAVEN closes a primary window into the atmospheric history of Mars. Because the spacecraft suffered a mechanical failure involving unexpected spinning, NASA cannot perform a controlled decommissioning, leaving the probe as a piece of orbital debris. Future missions will now rely on MAVEN's decade of data to calibrate new instruments designed to search for signs of ancient life.
