Mission concludes after eleven years
On 24 June 2026 NASA officially ended operations of the Mars Atmosphere and Volatile Evolution (MAVEN) orbiter. Launched in November 2013 and arriving at Mars in September 2014, the spacecraft completed its primary science objectives and was placed into a safe standby mode.
Key scientific findings
During its extended mission MAVEN measured the interaction of solar radiation, the solar wind, and the Martian atmosphere. The data confirmed that the planet has been losing a substantial portion of its original atmosphere to space over billions of years, primarily through atmospheric erosion processes.
Support for surface missions
Beyond its scientific payload, MAVEN acted as a communications relay for landers and rovers, including the Perseverance rover. By providing direct links to Earth, the orbiter increased the data return rates for surface assets.
Future prospects
Although MAVEN is now inactive, its extensive data archive will continue to be analyzed by researchers worldwide. The findings will inform upcoming Mars missions, especially planned orbiters that aim to conduct even more detailed atmospheric studies.
Overall assessment
International scientists describe MAVEN as one of the most successful Mars orbiters, noting its combination of robust atmospheric science and reliable communications support has significantly advanced our understanding of the Red Planet.
