MAVEN

NASA’s MAVEN mission investigated the Martian upper atmosphere, ionosphere, and interaction with the solar wind, while its communications package relayed data from surface missions. The Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder coordinated the science team, science operations and data management, and provided the Imaging Ultraviolet Spectrograph and Langmuir Probe and Waves instruments. The University of California, Berkeley Space Sciences Laboratory managed the particles-and-fields package and contributed instruments measuring solar-wind particles and energetic particles. These university teams also co-led education and public outreach.

Description
NASA’s MAVEN mission investigated the Martian upper atmosphere, ionosphere, and interaction with the solar wind, while its communications package relayed data from surface missions. The Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder coordinated the science team, science operations and data management, and provided the Imaging Ultraviolet Spectrograph and Langmuir Probe and Waves instruments. The University of California, Berkeley Space Sciences Laboratory managed the particles-and-fields package and contributed instruments measuring solar-wind particles and energetic particles. These university teams also co-led education and public outreach.
Destination
Elliptical Mars orbit at 75° inclination, with approximately 150 km periapsis and 6,000 km apoapsis (later reduced by aerobraking), for studying the upper atmosphere, ionosphere, and atmospheric escape while relaying data from surface missions
End Date
2026-06-03
Launch Site
Outcome
MAVEN entered Mars orbit in September 2014 and transformed understanding of atmospheric escape and solar-wind forcing. NASA declared the mission ended on June 3, 2026, after a December 2025 loss of signal and review-board determination that the spacecraft was unrecoverable.
