NASA ends MAVEN mission after a decade in Mars orbit

What's happened

NASA has ceased efforts to locate MAVEN after it lost contact behind Mars in December 2025. The mission, launched in 2013 to study Mars’ atmosphere, has been decommissioned following a review that concluded the spacecraft is no longer recoverable. MAVEN had provided key insights into atmospheric escape and acted as a communications relay.

What's behind the headline?

Analysis

• The story marks the end of a long-running mission that has shaped our understanding of Mars’ atmosphere. NASA has confirmed the decommissioning after attempting to recover the craft following a loss of signal as Mars occulted the spacecraft.
• The loss of MAVEN underscores the challenges of deep-space operations, where prolonged communications gaps can end a mission despite past successes.
• The coverage shows a consensus across outlets that MAVEN has advanced knowledge of atmospheric escape and planetary habitability; the scope now shifts to leveraging other orbiters for relay roles and to future missions that fill the data gaps MAVEN leaves behind.
• Readers should note the distinction between MAVEN’s scientific legacy and its practical end-of-life status, which affects ongoing data analysis and mission planning for Mars exploration.

How we got here

MAVEN arrived at Mars in 2014 to study the interaction between the Martian atmosphere and the solar wind. It exceeded its prime mission by years, delivering crucial data on atmospheric loss and helping relay information from rovers on the surface. In December 2025, MAVEN lost contact while behind Mars, leading NASA to begin recovery attempts that were unsuccessful and ultimately conclude with decommissioning.

Our analysis

Ars Technica reports MAVEN’s end after an 11-year mission and details the incompleteness of its recovery. France 24 highlights MAVEN’s scientific contributions and the ongoing investigation into the loss of contact. AP News and NY Post summarize NASA’s conclusion that MAVEN is unusable and cannot be recovered, while noting its role in relaying rover data.

• MAVEN - Former NASA Mars orbiter

  MAVEN is an inactive NASA spacecraft orbiting Mars that studied the loss of its atmospheric gases to space, providing insight into the history of the planet's climate and water. The name is an acronym for "Mars Atmosphere and Volatile Evolution" while the word maven also denotes "a person who has special knowledge or experience; an expert". MAVEN was launched on an Atlas V rocket from Cape Canaveral Air Force Station, Florida, on 18 November 2013 and went into orbit around Mars on 22 September 2014. It was the first NASA mission to study the Mars atmosphere. The probe analyzed the planet's upper atmosphere and ionosphere to examine how and at what rate the solar wind is stripping away volatile compounds. On 6 December 2025, MAVEN lost contact with Earth. Despite recovery efforts at NASA's Deep Space Network, contact could not be re-established as of January 2026. A review board was convened in February 2026, which determined the spacecraft was likely not recoverable. On 3 June 2026, NASA officially declared the spacecraft dead and its mission concluded. The principal investigator for the mission was Shannon Curry at the University of California, Berkeley. She took over from Bruce...
