Our latest assessment period over sols 3872 and 3873 was a "touch and go" plan: some contact science and other observations, followed by a drive. We performed some imaging and DRT (Dust Removal Tool) brushing on the "Madero" bedrock target, to allow for contact science using APXS.

Detailed analysis of data obtained by the Zhurong rover of dunes located on the southern Utopian Plain of Mars suggests the planet underwent a major shift in climate that accompanied changes in prevailing winds. This shift likely occurred about 400,000 years ago, which coincides with the end of the last glacial period on Mars.

Observations of two Type II supernovae, Supernova 2004et (SN 2004et) and Supernova 2017eaw (SN 2017eaw), have revealed large amounts of dust within the ejecta of each of these objects.
