Summary:
- NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft has experienced a problem with its power system, and the agency is pessimistic about the chances of recovering the spacecraft.
- MAVEN has been orbiting Mars since 2014 to study the planet's upper atmosphere and its interaction with the solar wind, which has helped scientists understand how Mars lost most of its atmosphere over time.
- The loss of MAVEN would be a significant setback for Mars exploration, as it is the only spacecraft currently studying the Martian upper atmosphere, which is crucial for understanding the planet's climate and habitability.
