NASA declares end to MAVEN Mars mission

Summary

NASA formally ended its Mars Atmosphere and Volatile Evolution (MAVEN) mission on June 3, six months after losing contact with the Mars orbiter in December. A review board concluded the spacecraft was unrecoverable following an anomaly. Controllers last heard from MAVEN on December 6, with subsequent efforts to restore communication unsuccessful. Investigators recovered telemetry, revealing the spacecraft was rotating at an unexpected 2.7 revolutions per minute, which drained its batteries. The root cause is under investigation, with a final report expected in months. Launched in November 2013, MAVEN entered Mars orbit in September 2014, primarily studying the planet's upper atmosphere and its interaction with solar wind. It also served as a crucial communications relay, handling 18% of data for surface missions. Its loss highlights the urgency for the Mars Telecommunications Network (MTN) mission, funded with \$700 million and required to launch by 2028, with proposals due June 15 and a contract by October 1. MAVEN is expected to remain in orbit for 50 to 100 years.

Key takeaway

For space mission planners and engineers developing future Mars endeavors, the MAVEN mission's end underscores the fragility of single-point communication assets. You should prioritize robust, redundant relay network designs and accelerate the deployment of dedicated infrastructure like the Mars Telecommunications Network. This ensures continuous data return and operational resilience, mitigating risks from unexpected spacecraft anomalies and safeguarding long-term scientific objectives.

Key insights

The MAVEN Mars mission concluded after an unrecoverable anomaly, underscoring the critical need for robust space communication infrastructure.

Principles

• Spacecraft anomalies require rapid telemetry analysis.
• Redundant communication networks are vital for deep space.
• Long-term orbital tracking prevents future collisions.

Method

Investigators analyzed recovered telemetry from a radio science experiment to determine the spacecraft's unexpected rotation rate of 2.7 RPM, leading to battery drain and unrecoverable status.

In practice

• Prioritize telemetry recovery post-anomaly.
• Invest in resilient relay networks like MTN.
• Conduct long-term trajectory propagation for defunct orbiters.
