Example count for the Crater Floor campaign


Perseverance has spent just over an Earth year in Jezero Crater. Over the past week, the team reached a very special milestone as we officially wrapped up our first scientific campaign focused on the bottom of Jezero Crater.

During our Crater Bottom campaign, we occupied Perseverance! As we learned more about our surroundings, we characterized the rocks that make up the crater floor into two formations, both of which we believe are of igneous origin. A formation is a geological term for a sequence of rocks large enough to be mapped on the surface and distinguishable from other formations.

The first formation encountered by Perseverance is the Máaz Formation, and within this we abraded 4 rocks and sealed 6 sample tubes. These tubes contain 4 rock core samples, an atmospheric sample and a control sample (intended for the evaluation of contamination). From the second formation in the crater floor, the Séítah Formation, we performed abrasions on 3 rocks and filled 4 sample tubes, all of which contain rock cores. All of this hard work brought the total number of sample tubes to 10 as a result of our investigation of the floor of Jezero Crater.

Next up for Perseverance is a phase we’re calling Rapid Traverse, or more colloquially, our “drive, drive, drive” campaign. As the names suggest, during this phase, it’s full steam ahead; we will try to make as much progress as possible on each soil, with the aim of reaching the location of our next scientific campaign as quickly as possible. While Perseverance is behind the wheel, the science team is busy planning our next campaign, which will take place in the Jezero Crater Delta. As a member of the Scientific Operations team, I am involved in both the development and execution of our sampling strategy and the campaign planning process for our upcoming delta campaign. I feel a deep sense of connection to the samples Perseverance is collecting in Jezero Crater, and I’m very excited to see what the delta has in store for us!
