Perseverance begins the Margin Campaign on Mars, exploring the origins and significance of Jezero Crater's marginal carbonates over the next 230 sols. This week on Mars, Perseverance officially kicked off the Margin Campaign by arriving at Mandu Wall and performing the first abrasion of a rock
, using a combination of autonomous and directed drives to dodge hazards in the rough terrain.
The lithological boundary at Mandu Wall marks an important waypoint along the climb towards Jezero Crater’s rim, as it comprises an abundance of carbonate-bearing rocks hypothesized to have formed through precipitation, as a result of aqueous activity that dominated the once-watery Martian surface several billion years ago. Water-driven alteration of igneous minerals is another possible mechanism that could explain the carbonate’s origin.
The Margin Campaign is dedicated to exploring the origin, alteration, and astrobiological relevance of thethat circle the upper edge of Jezero Crater.
This fourth segment of the Mars 2020 mission is expected to take about 230 sols and will see Perseverance rove across the marginal carbonates and up to Jezero Crater’s rim, stopping to conduct remote and proximity science observations and drill up to 4 cores along the way.
In the near term, proximity science observations of the new “Amherst Point” abrasion patch at Mandu Wall are planned for the next few sols as the Margin Campaign marches on. Once downlinked to Earth, this data collected by
