NASA formally ended the MAVEN Mars atmospheric orbiter mission on June 3 after the spacecraft remained out of contact for six months [1].
The termination of the mission marks the conclusion of a primary effort to understand how Mars lost its atmosphere over billions of years. The loss of the orbiter removes a critical piece of infrastructure for real-time atmospheric monitoring around the red planet.
Mission control at NASA Headquarters in the U.S. said the decision followed investigations that concluded the spacecraft could not be recovered [1], [2]. The orbiter had been missing for six months [1] before the agency declared the mission dead.
MAVEN operated at Mars for more than 10 years [3]. During its tenure, the spacecraft studied the Martian upper atmosphere and the effects of solar wind on the planet's gaseous envelope. The mission provided data that helped scientists determine why Mars transitioned from a potentially habitable world to a cold, dry desert.
NASA officials said the decision to end the mission followed a period of silence that began six months ago. While the agency did not specify the exact cause of the failure, the lack of communication over such a long duration indicated a catastrophic loss of function [2], [4].
The agency's announcement was made during a public teleconference to bid farewell to the spacecraft [5]. This concludes the operational phase of a mission that spanned more than 10 years of active observation [3].

The end of MAVEN represents a transition in Martian exploration from active atmospheric monitoring to the analysis of archived data. While the loss of the orbiter is a setback for current observations, the decade of data collected provides a foundational baseline for future missions seeking to understand planetary evolution and the viability of life on Mars.
