NASA has officially declared the MAVEN Mars orbiter dead after months of radio silence followed a technical anomaly [1].
The loss of the spacecraft ends a mission that provided critical data on the Martian atmosphere. Because MAVEN studied how Mars lost its water and air over time, its absence leaves a gap in the active monitoring of the planet's upper atmosphere.
Contact with the orbiter was lost on Dec. 6, 2023 [2]. NASA officials spent several months attempting to re-establish a link with the craft before announcing the mission's end in June 2024 [2].
Investigations revealed that an anomaly in the spacecraft’s rotation speed caused an unexpected loss of power [3]. This failure prevented the orbiter from maintaining the necessary energy to transmit signals back to Earth, leading to the eventual termination of the mission [3].
The orbiter operated for about 12 years [4]. During this period, which spanned more than a decade, the mission provided a wealth of data regarding the Red Planet [4].
Although the mission is over, the spacecraft remains in orbit around Mars. NASA expects the dead orbiter to eventually crash into the planet's surface within the next 100 years [4].

The termination of MAVEN marks the end of a primary source of atmospheric data for Mars. While the mission exceeded its expected lifespan, the loss of the orbiter emphasizes the risks of long-term autonomous operations in deep space, where a single mechanical anomaly in rotation or power can lead to the total loss of a multi-decade scientific asset.
