Early observations from the ExoMars Trace Gas Orbiter show that, in contrast to previous work, the orbiter did not detect methane on Mars, which raises questions about the reasons for these discrepancies. A second paper describes a rare Martian global dust storm, which may help us to understand how such events affect the Martian atmosphere.
