What does outgassing mean?
The process by which a substance releases gas, especially a gas that was trapped or dissolved within it. This can occur naturally, such as in the case of volcanic eruptions, or artificially, such as in the case of spacecraft venting gases.
Example
"The spacecraft's outgassing was a major concern for the mission planners, as it could affect the performance of the satellite's instruments."
