Ridiges of South Seitah


NASA’s Perseverance rover captures a geologic feature with details that offer clues to the area’s mysterious past.

Ask any space explorer, and they’ll have a favorite photograph or two from their mission. 

For Jorge Núñez, an astrobiologist and planetary scientist working on the science team of NASA’s Perseverance rover, one of his current favorites is a rover’s-eye panorama of the “South Séítah” region of Mars’ Jezero Crater. 

Exploring the geologic unit was among the major objectives of the team’s first science campaign because it may contain some of the deepest, and potentially oldest, rocks in the giant crater.

“Just like any excited tourist approaching the end of a major road trip, we stopped at a lookout to get a first view of our destination,” said Núñez, who is based at Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. 

“This panorama is spectacular because you feel like you are there. It shows not only the incredible scale of the area, but also all the exploration possibilities South Séítah has to offer. With multiple intriguing rocky outcrops and ridgelines, each one is seemingly better than the last. If it’s not a field geologist’s dream, it’s pretty close.”

Composed of 84 individual enhanced-color images that were later stitched together, the mosaic was taken on September 12 (the 201st Martian day, or sol, of the mission) by the Mastcam-Z camera system as the rover was parked on an elevated overlook just outside its entry point into South Séítah. 

Perseverance had just completed a record 190-yard (175-meter) drive the previous sol.  READ MORE...
