Nasa declared the mission of the Maven probe on the planet Marte closed. The North American space agency confirmed this Wednesday, June 3, 2026, the end of operations after more than six months of total silence. The spacecraft, which had been orbiting Marte since 2014, stopped responding in December 2025.
A technical review board concluded that recovery is impossible. The problem occurred when Maven passed behind Marte and did not reappear with a signal. Dados indicate that the probe entered a rapid rotation, which compromised orientation and exhausted the batteries.
Falha technique drove Maven into safe mode without recovery
Maven lost contact on December 6, 2025. The probe was trying to communicate after a period of solar conjunction, when Marte is on the opposite side of Sol in relation to Terra. Equipes from Nasa used the Deep Space Network network and the Green Bank observatory to try to reestablish connection.
Nenhum signal has been recovered. Excessive rotation prevented the solar panels from recharging the batteries. The anomaly board, formed in early 2026, analyzed the available data and pointed out that the spacecraft is no longer capable of operating.
- Maven entered safe mode while passing behind Marte
- Rotação quickly disoriented solar panels
- Baterias are sold out without the possibility of refilling
- Tentativas of recontact lasted months without success
- Revisão technical in February 2026 confirmed irreversible loss
Lançada in 2013, probe exceeded initial expectations of two years
Maven took off in November 2013 and arrived at Marte in September 2014. The main mission expected only one year of operations. However, the spacecraft operated for more than 11 years. Ela studied the Martian atmosphere and how the solar wind removed gases over time.
Cientistas highlight that the data helped to understand the evolution of the red planet. The probe detected proton auroras, tracked the escape of argon into space and linked dust storms to water loss. Além also served as a relay for the Curiosity and Perseverance rovers.
Contribuições scientists from Maven scheduled research on Marte
Maven has produced more than 800 scientific publications. Shannon Curry, mission principal scientist and researcher for University of Colorado Boulder, summarized the spacecraft’s legacy. Ela has advanced knowledge about the Martian atmosphere and its evolution over billions of years.
The probe observed an interstellar comet that passed close to Marte. Também recorded climate variations and helped plan future manned missions. The role as a relay allowed rovers on the surface to send record volumes of data to Terra.
Encerramento of Maven leaves orbit of Marte with less support
With the end of Maven, Nasa loses an important observation and communication tool in Marte. Outras missions still operate on the planet, but the orbital support network is reduced. The agency must evaluate how to redistribute functions among the remaining spacecraft.
The case of Maven reinforces the challenges of maintaining equipment in operation for more than a decade in the hostile environment of deep space. Investigação on the exact cause of the failure remains ongoing.
