Searching for new gases in the Martian atmosphere
Today’s Video of the Day from the European Space Agency describes the mission of the ESA-Roscosmos ExoMars Trace Gas Orbiter to search for new gases and their sources in the atmosphere surrounding Mars.
For example, ExoMars discovered that hydrogen chloride appeared during a global dust storm in 2018 and then disappeared again.
According to the ESA, seasonal change that triggers dust activity is thought to be the driving force behind the observation.
