NASA announced on Wednesday that it will officially end its mission to study the atmosphere and evolution of Mars after its probe, MAVEN (Mars Atmosphere and Volatile Evolution), went silent for six months. The spacecraft, which entered Martian orbit in 2014, was initially designed to operate for one to two years but remained active for over a decade before losing contact with Earth in December 2025.
After months of unsuccessful attempts to re-establish communication, NASA has accepted the loss of the spacecraft, which is believed to still be orbiting Mars. The US space agency stated that it will investigate the cause of the communication failure.
Scientific Contributions
Shannon Curry, an astrophysics professor involved in the mission, described MAVEN as the "best Mars mission ever." The probe allowed scientists to study atmospheric escape—the process by which atmospheric gases are lost to space. "We now have a better understanding of atmospheric escape at Mars than at any other planet, including Earth, and consequently Mars serves as an incredible natural laboratory for understanding rocky planet atmospheres," Curry told reporters.
Tiffany Morgan, NASA's exploration program chief, noted that MAVEN "profoundly advanced our understanding of Mars's atmosphere, climate history, and habitability." The probe also served as a critical communications relay between Earth and NASA's rovers on the Martian surface. Other orbiters will now need to take over these relay duties.
Legacy of MAVEN
MAVEN's decade-long mission provided invaluable data on Mars' atmospheric evolution, shedding light on how the planet transitioned from a potentially habitable world to the cold, dry desert it is today. The loss marks the end of a significant chapter in Mars exploration, but the data collected will continue to be analyzed for years to come.
