NASA's next mission to Mars went through testing Monday, prior to launch just under a month away.
The Mars Atmosphere and Volatile EvolutioN (MAVEN) mission is part of NASA's Mars Scout program.
It is scheduled to launch on November 18, 2013.
MAVEN went through a 'spin test', which checks the balance and stability of the spacecraft at various revolution rates.
If successful, the next step is to fuel the spacecraft.
NASA says MAVEN data will "determine the role that loss of volatile compounds—such as carbon dioxide, nitrogen dioxide, and water—from the Mars atmosphere to space has played through time, giving insight into the history of Mars' atmosphere and climate, liquid water, and planetary habitability."
NASA continues to look for life on Mars and this next mission will address that issue.
