NASA’s Perseverance Rover captures detailed geological features that provide clues to the region’s mysterious past.


Ask space explorers and they have one or two favorite photos from their mission. For astrobiologist and planetary scientist Jorge Nuñez, who works for NASA’s Perseverance Rover science team, one of his current favorites is the Rover’s Eyes in the “South Seita” region of the Martian Jezero Crater. It is a panorama of. Exploration of geological units was one of the main objectives of the team’s first scientific campaign. Because it may contain some of the deepest and potentially oldest rocks in the giant crater.

Nunez, based at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, said, “To get the first view of your destination, just like excited tourists approaching the end of a major expedition. I stopped by with an eye out. ” “This panorama is spectacular because it feels like it’s there. This panorama shows not only the incredible scale of the area, but also all the exploration possibilities that South Seita offers. Multiple interesting There are rock outcrops and ridges, each of which seems to be better. Last. If it’s not the dream of a field geologist, it’s pretty close. “

Consisting of 84 individually highlighted images that were later stitched together, the mosaic was created by the Mastcam-Z camera system on September 12 (Mission 201 Mars Day, or Zol) when the Rover was parked elevated. It was taken. It overlooks just outside the entrance to South Seita. Patience has just completed a record of driving 190 yards (175 meters) in front of the sol.

The mosaic was shot at maximum magnification and stretched so that subtle color differences between rocks and soil were visible to the naked eye. The left side of the center and half of the image are the gray, dark gray, Swiss coffee-colored rocky dew of the ridge called “Faillefeu” (named after a medieval monastery in the French Alps). The apparently thin, sometimes sloping layered structures found in some of Faillefeu’s rocks are at the top of the scientific team’s list of subjects, as the sloping layered structure suggests potential structural activity. However, along with other compelling geology, similar functionality appeared on another ridgeline that the mission’s science team chose to explore instead.

The “Martre Ridge” (named after the commune in southeastern France) is similar to Faillefeu except that it is three times as large. It contains not only lowland flat rocks near the base of the ridge, but also rock outcrops with a thin layer at the base and a huge caprock near the top of the ridge. Caprocks are usually made of a harder, more resistant material than the ones stacked underneath, suggesting potential differences in the way the materials are deposited.

“Another great thing about this image is that on the right side of the background, you can see the path of patience on the way to South Seita,” says Nunez. “And finally, there is a peak of” Santa Cruz “in the distance. Currently, I have no plans to go there. It’s too far. But it’s geologically interesting and shows how great the team is strengthening. You can choose here at Jezero. That is also cool. ”
