Sols 4366–4367: One of Those Days on Mars (Sulfate-Bearing Unit to the West of Upper Gediz Vallis)

The Monday plan and drive had executed successfully, so the team had high hopes for APXS and MAHLI data on several enticing targets in the rover’s workspace. Alas, it was not to be: The challenging terrain had resulted in an awkwardly perched wheel at the end of the drive, so we couldn’t risk deploying the arm from this position. Maybe next drive!
