Just Keep Roving

Image from Perseverance’s Right Navigation Camera, looking back towards rover tracks from past drives, into Jezero crater. The camera is located high on the rover mast, and here the rover is looking back in the direction of the Jezero crater floor. This image was acquired on October 4th, 2024 (Sol 1288) at the local mean solar time of 12:51:26.

Throughout the past week, Perseverancehas continued marching up the Jezero crater rim. This steep ascent through the Martian regolith (soil) can prove to be slow driving for the rover, as the wheels can slip on the steepest areas. This is like trying to run up a hill of sand on a beach – with every step forward, you also slip back a little way down the hill! This just means the Science and Engineering teams work together closely to plan slow and steady drives through this tricky terrain.

Driving through the Mount Ranier quadrangle, the team identified a relatively obstacle-free path to reach the crater rim which they designated Summerland Trail, aptly named from a very popular hiking trail that ascends Mount Ranier. Perseverance is trekking to the next waypoint near an outcrop of rocks called Pico Turquino, where the science team hopes to perform its next proximity science investigations with its instruments PIXL and back-online SHERLOC.

While roving along Summerland Trail, Perseverance is constantly observing the surrounding terrain. SuperCam and Mastcam-Z have been observing rocks on the ground and on a distant hill, called Crystal Creek. In addition, during this time Perseverance can put its eyes to the sky to make observations of the sun and atmosphere. Last week, the Mastcam-Z camera captured images of Phobos (one of Mars’ two moons) transiting in front of the sun!

This image, showing Phobos transiting in front of the sun, was acquired using Perseverance’s Left Mastcam-Z camera. Acquired on September 30th, 2024 (Sol 1285) at the local mean solar time of 11:10:04.

While the Mars2020 team is itching to reach the ancient stratigraphy exposed in the crater rim, for now, the focus is on documenting our surroundings while navigating the ascent.
