NASA announced that the MAVEN Mars orbiter is officially dead following months of radio silence [1].
The loss of the spacecraft ends a primary mission to study the Martian atmosphere and understand how the Red Planet lost its water. MAVEN provided critical data on the evolution of the Martian climate, which helps scientists determine if the planet was once habitable.
According to NASA, an onboard anomaly caused the orbiter to spin out of control [1]. This malfunction led to a total loss of communication between the spacecraft and mission control. The agency spent several months attempting to re-establish contact before making the official declaration [1].
The mission lasted between 11 [3] and 12 years [1] of productive exploration. During this time, the orbiter circled the planet to analyze the upper atmosphere, and the effects of solar wind. The discrepancy in mission length reflects different reporting periods for the operational phase of the craft.
While the orbiter is no longer functional, it remains in space. NASA officials said the spacecraft is expected to crash into Mars within the next 100 years [2]. Until that event occurs, MAVEN will continue to drift in a decaying orbit around the planet.
NASA did not provide specific details regarding the nature of the anomaly that triggered the spin. The agency said its final reports focused on the legacy of the data collected during the decade of operation [1].

The conclusion of the MAVEN mission marks the end of a dedicated era of atmospheric monitoring at Mars. While the loss of the hardware is a setback, the decade of accumulated data provides a baseline for future missions to understand planetary atmospheric escape. The eventual crash of the orbiter serves as a reminder of the long-term orbital debris challenges associated with deep-space exploration.
