MAVEN
The Mars Atmosphere and Volatile Evolution (MAVEN) mission is the first mission devoted to understanding the Martian upper atmosphere.
The Mars Atmosphere and Volatile Evolution (MAVEN) mission has helped scientists determine how much of the Martian atmosphere has been lost over time by measuring the current rate of escape to space and gathering enough information about the relevant processes to allow extrapolation backward in time.

NASA Anomaly Review Board Investigates MAVEN Loss of Signal
NASA convened the review board in mid-February, to evaluate the recovery efforts undertaken for the MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft orbiting Mars. The spacecraft was last heard from on Dec. 6. The board also will assess the probable current state of the spacecraft and the likelihood of its recovery.<br>Among other efforts, the agency has been working to reconnect with MAVEN using NASA’s Deep Space Network and the U.S. National Science Foundation’s Green Bank Observatory.

Citizen Science Project
Using data collected from MAVEN's Imaging Ultraviolet Spectrograph (IUVS), you can help answer questions about Mars' atmosphere and climate. Questions include:
- What are the daily, seasonal, or annual patterns in Martian cloud shapes and distributions?
- How well do cloud forms reflect prevailing wind patterns?
- Do the structural similarities between Earth's and Mars' cloud types point to similar formation mechanisms?
