NASA's Perseverance Mars Rover

Perseverance discovered rocks filled with parallel mineral veins similar to ones on Earth referred to as “beef”. But now close-up images reveal that the veins are clogged with bits of other rocks and minerals that changes the origin story.

This channel follows the exploration of Jezero crater by the Perseverance rover and Ingenuity helicopter, presenting science, engineering, and the search for life on Mars using a novel in-person experience.

This project was initiated in part with collaboration from the NASA Infiniscope project.

After months of driving, Perseverance has finally arrived at ‘Bright Angel’, discovering oddly textured rock unlike any the rover has seen before. The team now plans to drive up the slope to uncover the origin of this rock sequence and its relationship to the margin unit.

Having completed a survey of the intriguing and diverse boulders at 'Mount Washburn,’ the rover headed north, parking just in front of an exposure of layered light toned rock. This provided the team with our first close-up look of the rocks that make up the ‘Bright Angel’ exposure, so Perseverance stopped to acquire images, before driving west to a larger and more accessible outcrop where the rover will conduct detailed exploration.

Perseverance arrived at the base of this outcrop on sol 1175, and geologists on the science team were mesmerized by the strange textures of the light toned rocks found there. These rocks are filled with sharp ridges that resemble the mineral veins found at the base of the fan, but there appears to be more of them here. Additionally, some rocks are densely packed with small spheres, and we’ve jokingly referred to this as a ‘popcorn’-like texture. Together, these features suggest that groundwater flowed through these rocks after they were laid down. Next, Perseverance will gradually ascend up the rock exposure, taking measurements as it goes. Over the weekend, the abrasion tool will be used to take a close-up look and acquire detailed chemical information using the instruments on the rover’s arm. With this data in hand, the team will decide whether or not to sample. Once our exploration at ‘Bright Angel’ is complete, we will drive south back across Neretva Vallis and explore a site called ‘Serpentine Rapids’.

The light toned bedrock is 'Bright Angel'. Possibly the oldest rocks in the crater. It was selected for investigation prior to landing.

When the rover is finished at this location it will begin the drive out of the crater...

Bright Rocks and “Bright Angel” - Perseverance Rover mission update, June 10, 2024.

Last week the Perseverance rover descended into Neretva Vallis, an ancient river channel that brought water into Jezero Crater billions of years ago. Rocks found in Neretva Vallis could have come from far upstream, giving us the opportunity to examine material which may have come from many kilometers away. Turning north into the channel has allowed us to complete longer drives, a refreshing change of pace from the rugged terrain we tackled in the Western Margin.

Dodging dunes at Dunraven Pass, we approached Mount Washburn, an outcrop which our Mastcam-Z camera identified from a distance as having spectrally diverse boulders and patches of lighter-toned bedrock. Upon arriving, we were amazed by the variety of colors and textures in the rocks around the rover and immediately got to work planning observations with our remote sensing instruments. Much of our focus was on “Atoko Point”, a bright boulder with dark speckles. After acquiring numerous Mastcam-Z multispectral images and zapping Atoko Point with our SuperCam laser, we began to look towards our next goal: “Bright Angel”. This exposure of light-toned rock, northwest of our current location, stands out vividly in orbital imagery. By examining outcrops at Bright Angel and assessing stratigraphic relationships (i.e. the vertical sequence and stacking of different sets of rocks), it is hoped that we can understand its connection to Neretva Vallis and the crater rim.

Intrigued by what we have found at Mount Washburn, our first stop in the channel, we have now turned to the terrain to the north, where we will add yet another chapter to Perseverance’s story at “Bright Angel”.

Mars Guy - Episode 166 In its search for evidence of ancient microbial life on Mars, Perseverance collected the most promising samples early in the mission at a place affectionately known as the bacon strip. Now it may have come across another one.

Faced with weeks of driving across treacherous rocks or a shortcut across a potential sand trap, Perseverance broke on through the sand and found an island littered with rocks like none ever seen before on Mars.
