NASA officially ended the MAVEN Mars-orbiter mission on Wednesday after the spacecraft experienced six months of radio silence [4], [6].
The loss of the probe marks the end of a long-term effort to study the Martian atmosphere. Because the spacecraft is no longer communicating with Earth, the agency can no longer collect data on how Mars loses its atmosphere to space.
MAVEN was launched in 2013 [1] and entered orbit around Mars in 2014 [2]. While the mission was originally planned to last only one to two years [5], it continued to provide valuable scientific data for more than a decade [3].
The agency declared the spacecraft dead after months of attempting to re-establish contact. The probe had fallen silent in December 2025 [7], a period of radio silence that lasted half a year before the official termination announcement [4].
NASA officials said the mission's longevity allowed for a comprehensive understanding of the Red Planet's evolution. The spacecraft's ability to operate for approximately 11 years [3] provided a window into the planet's atmospheric history that far exceeded initial expectations.
Despite the loss of the orbiter, the data collected over the last 12 years remains available to the scientific community. The agency said the mission's end is a result of the total loss of contact, leaving no viable way to command the craft or retrieve further telemetry.
“NASA officially ended the MAVEN Mars-orbiter mission on Wednesday after the spacecraft experienced six months of radio silence.”
The termination of MAVEN represents the conclusion of a primary atmospheric study of Mars. By operating for 11 years instead of two, the mission provided a longitudinal dataset that helps scientists understand the transition of Mars from a potentially habitable world to a frozen desert. The sudden loss of contact underscores the inherent risks of long-term deep-space hardware degradation.
