NASA declared the MAVEN Mars orbiter dead on Wednesday after the spacecraft suffered a loss of contact following a critical onboard anomaly [1], [3].
The loss of the orbiter ends a long-term study of the Martian atmosphere, removing a key source of data on how the Red Planet lost its water and air over time.
According to NASA, the spacecraft began spinning out of control after the anomaly occurred [1], [3]. This instability prevented the orbiter from maintaining a stable communication link with Earth, resulting in several months of radio silence [1]. Despite efforts to re-establish contact, the agency said the mission is over [3].
MAVEN provided a significant amount of data during its operational life. Reports on the total duration of the mission vary slightly, with some sources citing an 11-year exploration [3] and others describing a dozen productive years [2]. This discrepancy reflects the time between the initial launch and the final period of active data transmission.
While the spacecraft is no longer functional, it remains in orbit around Mars [1]. It is not expected to leave the area immediately. Projections indicate the dead orbiter will eventually crash into the surface of the Red Planet within the next 100 years [2].
NASA officials did not provide specific details regarding the nature of the anomaly that caused the spin. The agency said the mission is now concluded [3].
“NASA declared the MAVEN Mars orbiter dead on Wednesday.”
The termination of the MAVEN mission represents a loss of real-time atmospheric monitoring for Mars. While the data collected over the last 11 to 12 years remains available for study, the absence of a dedicated orbiter for this specific purpose may slow the pace of discovery regarding Martian climate evolution until a replacement mission is deployed.
