NASA Ends MAVEN Mars Mission

NASA declared the Mars Atmosphere and Volatile Evolution (MAVEN) mission concluded on 3 June 2026 after a prolonged loss of contact with the spacecraft. MAVEN was launched in November 2013 and operated for more than 11 years in orbit around Mars.

MAVEN Mission Profile

MAVEN stands for Mars Atmosphere and Volatile Evolution. It was a NASA orbiter designed to study the upper atmosphere of Mars and the planet’s atmospheric escape processes. The spacecraft exceeded its primary one-year mission and continued scientific operations for over a decade. MAVEN also served as a data relay orbiter for NASA’s Curiosity and Perseverance rovers.

Loss of Contact and Anomaly Review

The last successful communication with MAVEN took place on 6 December 2025 before a scheduled occultation behind Mars. NASA’s Deep Space Network did not detect a signal when the spacecraft was expected to re-emerge. Brief telemetry data showed that MAVEN entered safe mode and began rotating at an unusually high rate. The rapid spin is believed to have drained the onboard batteries and cut power to the communications system. An anomaly review board convened by NASA in February 2026 determined that the spacecraft could not be recovered and could no longer perform its science and data relay missions. The final root-cause report is expected later in 2026.

Scientific Role of MAVEN

MAVEN studied how the Sun and solar activity contributed to the loss of most of Mars’s atmosphere over geological time. Its findings are linked to the transition of Mars from a warmer and wetter planet to a dry and cold world. The mission formed part of NASA’s Mars exploration programme and added atmospheric data to the broader study of Martian climate history.
