NASA has declared its MAVEN spacecraft orbiting Mars officially dead and unrecoverable after a total loss of signal [1, 2].
The loss of the probe ends a primary mission that provided critical data on the Martian atmosphere and its evolution over time. By confirming the spacecraft is in an unrecoverable state, the agency can now transition from recovery efforts to the final analysis of the data already collected [1, 3].
Contact with the spacecraft was first lost in December 2023 [4, 5]. NASA spent approximately six months attempting to re-establish communication before announcing the mission's end in June 2024 [5, 6]. The probe had been operating for 11 years prior to the loss of contact [7].
Technical reports indicate that an anomaly in the spacecraft’s rotation speed caused an unexpected loss of power [1, 8]. This malfunction occurred while the craft was positioned behind Mars, cutting off the line of sight to Earth. While the rotation speed is cited as the trigger for the power failure, the precise root cause of the anomaly remains unknown [8].
MAVEN, which stands for Mars Atmosphere and Volatile Evolution, was designed to study the upper atmosphere and the way the solar wind stripped away the planet's water. The mission's 11-year tenure provided a vast archive of information regarding the planet's transition from a warmer, wetter world to the cold desert seen today [7].
NASA officials said the spacecraft is now considered dead. The agency will focus on the scientific legacy of the mission, and the data transmitted before the signal vanished [1, 2].
“NASA has declared its MAVEN spacecraft orbiting Mars officially dead and unrecoverable.”
The loss of MAVEN represents the end of a decade-long window into the Martian atmosphere's interaction with solar radiation. While the primary mission is over, the existing data set will likely serve as the baseline for future missions attempting to understand if Mars ever supported life, as the probe's findings on atmospheric escape are central to that determination.
