June 3 (UPI) — NASA has officially concluded the Mars Atmosphere and Volatile Evolution (MAVEN) mission after losing contact with the spacecraft, marking the end of a groundbreaking 11-year exploration of Mars’ atmosphere.
The last communication from MAVEN was received on December 6, 2024, when the satellite passed behind Mars. Despite efforts to reestablish contact, no signals were detected, leading NASA to declare the mission unrecoverable. The agency is investigating the cause, though preliminary analysis suggests the spacecraft may have been spinning excessively, depleting its batteries and preventing it from reestablishing communication.
Launched in November 2013 aboard an Atlas V rocket, MAVEN was designed to study the Martian atmosphere and its interaction with solar wind. Originally slated for a one-year mission, it operated far beyond its expected lifespan, providing critical insights into Mars’ atmospheric evolution and its transformation from a potentially habitable world to the arid planet we see today.
“MAVEN’s contributions have fundamentally reshaped our understanding of Mars’ atmospheric dynamics,” said Shannon Curry, MAVEN’s principal investigator and a professor at the University of Colorado Boulder. “The data collected will continue to inform future missions and our broader goals in planetary science.”
Throughout its mission, MAVEN made several key discoveries, including the detection of unique auroras on Mars and detailed analyses of its dust storms. It also served as a vital communication relay for NASA’s Mars rovers, including Curiosity and Perseverance, until other orbiters took over this role.
“The insights from MAVEN are essential for planning human missions to Mars,” said Louise Prockter, director of NASA’s planetary science division. “Understanding the planet’s atmospheric and radiation environment is critical for ensuring the safety of future astronauts.”
While MAVEN’s operational life has ended, its legacy endures. The mission’s data will remain a cornerstone for future research, offering a wealth of information on planetary atmospheres and the processes that shape them. NASA’s Mars Reconnaissance Orbiter and Odyssey spacecraft will continue to support surface missions, ensuring the continuity of exploration efforts.
As the scientific community reflects on MAVEN’s achievements, the mission stands as a testament to the
