Exploring the Depths of Gale Crater: The Last Day on Highfield for Curiosity Rover

Last week, the Curiosity rover completed its final activities at the Highfield drill site. As the Surface Properties Scientist on duty, I noticed that there were no new tasks requiring my analysis. However, the science team was busy filling two science activity blocks with various observations. These observations included targeted imaging with Mastcam and compositional analysis with the ChemCam instrument, closing out any remaining tasks from previous plans.

On the first planned sol, the rover will use the MAHLI instrument to capture high-resolution microscopic images of the Highfield “dump pile.” This is where the rover discards excess sample material. Additionally, the APXS instrument will be placed on the “dump pile” to conduct further analysis. These analyses are crucial in providing insight into the composition of the inner parts of the rock, as opposed to the often weathered exterior.

In addition to these activities, the rover also conducted long-distance imaging to assist in planning the route up Mt. Sharp for future missions in the coming months and years. This strategic planning will help ensure that
