Last week on Mars, dust-lifting events continued over southern Aonia and Sirenum. The eastward movement of these storms lofted dust into the Argyre impact basin on multiple sols. The Hellas impact basin, on the other hand, was largely unobscured from atmospheric dust — making the floor discernible most afternoons. Moving our attention to the northern lowlands, a mixture of dust and water ice clouds remained along the receding seasonal north polar ice cap edge.
