NASA has officially ended the mission of the MAVEN (Mars Atmosphere and Volatile Evolution) probe after losing contact with the spacecraft in December 2025. Despite extensive attempts by NASA to re-establish communication via the Deep Space Network, the agency confirmed the probe is non-recoverable and can no longer perform scientific tasks or transmit data.
Why Did the MAVEN Mission End?
The MAVEN probe, launched in November 2013 on an Atlas V rocket from Cape Canaveral, reached Mars in September 2014. According to NASA, the spacecraft went silent in December 2025 while positioned on the side of Mars facing away from Earth. Although the agency detected the probe again in February 2026, it failed to respond or provide scientific data. A committee tasked with evaluating the situation concluded that the mission could no longer proceed. While the loss of contact was unexpected, Mike Morrow, project manager at NASA’s Goddard Space Flight Center, noted that the probe’s ultimate fate remains consistent with its original design. It will continue to orbit the planet for 50 to 100 years before gradually descending into the Martian atmosphere.
What Is the "Martian Orbital Graveyard"?
MAVEN joins a growing list of defunct spacecraft orbiting the Red Planet. Since the success of the U.S. Mariner 9 in 1971, at least 16 orbital missions have reached Mars, deployed by space agencies from the United States, the Soviet Union, the European Space Agency, India, the United Arab Emirates, and China.
Currently, only six orbiters remain operational:
- Mars Odyssey
- Mars Express
- Mars Reconnaissance Orbiter
- ExoMars Trace Gas Orbiter
- Hope Probe
- Tianwen-1
Other missions, such as the Soviet Mars 2, 3, and 5, or NASA’s Mars Global Surveyor, have either lost contact or ended their scientific service. This orbital collection sits alongside surface relics like the Spirit and Opportunity rovers, the Ingenuity helicopter, the Pathfinder lander, and the Chinese Zhurong rover. Only Curiosity and Perseverance remain active on the Martian surface.
Did you know?
MAVEN stands for "Mars Atmosphere and Volatile Evolution." The mission was specifically designed to uncover how the Red Planet transformed from a warm, moist environment into the cold, dry desert observed today.
What Scientific Legacy Does MAVEN Leave Behind?
MAVEN’s primary contribution to planetary science was identifying the mechanisms behind the loss of Mars’ atmosphere. Data collected over its decade-long mission confirms that solar winds gradually stripped away the planet’s once-thick atmosphere. According to NASA, this process occurred between 4.2 and 3.7 billion years ago—roughly the same era when life was beginning to emerge on Earth. By determining how gases were lost over time, MAVEN provided essential insights into the habitability of planets within our solar system and beyond.
Frequently Asked Questions
Is MAVEN still orbiting Mars?
Yes. According to NASA, the probe remains in an orbit similar to its operational path and will continue to circle the planet for several decades before eventually falling into the atmosphere.
Why couldn’t NASA fix the probe?
Following the loss of contact in December 2025, engineers spent months sending commands and attempting to restore the link. After detecting the probe in February 2026 without receiving a response or data, a review committee determined it was non-recoverable.
How many spacecraft are currently active on Mars?
As of June 2026, there are six operational orbiters and two active rovers (Curiosity and Perseverance) on the surface.
Will NASA release more information?
Yes. NASA has confirmed it is continuing to investigate the cause of the communication failure and plans to publish a detailed final report later this year.
