Just a feeling based on the fractures, that’s why I put it out there and asked the question. When we’ve seen mineral filled fractures in rocks on Mars the fractures have usually been in fairly straight lines following the crystalline structure in the host rock, or at separations of the sedimentary layers. It could be an optical illusion, but many of the fractures are far from straight in this target, almost like series of large crystals in a honeycomb like arrangement. The appearance of sandstone could just be a dust covering. Appreciate the feedback :)
Looking forward to hearing how the team call this float rock :)
Edit: fixed typo
The distance of the drive was 12.7 meters (41.7 ft) towards the Northwest.
During the drive the rover climbed 1.4 meters (4.6 ft).
The rover is now at site number 54.1010, stationed in the Northeast of a major science waypoint called ‘Bright Angel’.
The latest map (after a few more drives) should give you a clue ;)
Looks that way (IMHO) I believe it likely that they drove over there to investigate the step in the bedrock. We’ll know more when they release the mission blog
Not intentional (this time) but they have done that in the past (a long time back)
Thank you for the additional information :).
You’re most welcome. I’ll post any updates from the science team, but they are fairly rare

It is possible, as the rover is heading for Bright Angel (BA) it’s the west of the current location. This float rock could be from Bright Angel, so could have been washed down Neretva Vallis by floods etc ~3 billion years ago. BA appears to the white in the HIRISE images, BA is thought to be the oldest rocks the rover will encounter and probably predate the impact that formed the crater, so they could be of volcanic origin… Watch this space
Edit. fixed typos
Yes - 1 Sol is a Martian Solar Day ~39.5 minutes longer than an Earth day
The average duration of the day-night cycle on Mars - i.e., a Martian day - is 24 hours, 39 minutes and 35.244 seconds
It’s assembled from 15 overlapping images using MS-ICE. It’s fully a fully automated process for the assembly, but always seems to favour the terrain rather than the arm name plate. I guess there are more matching control points on the terrain 😊
The stitching software concentrates on the ground, not on the name tag :) Hence the §
I don’t have tools to scale these images properly, but I estimate the fractured rock is around 50cm to 75 cm wide
You’re most welcome :)
Correct that’s the 2 calibration targets for the mast cameras. It’s not an automatic calibration though in the camera, they image the cal targets regularly and then use those images later in the lab to calibrate the images that come down from the rover. The early colour images that arrive from the rover that we see on the public image server are uncalibrated and compressed for public release, that compression alters the colours a little (adds a green hue, the amount of green depends on the level of compression) I removed that green hue on this post.

Cliffs and Mars rovers are probably best kept apart, but the rover drivers are usually more afraid of the soft sands…
Mars Days, but a Mars day is a little longer than Earth days. It’s about 40 minutes longer.
So today in Gale crater it is currently Sol 4182… That’s 4297 earth days since the rover landed on August 6, 2012. Or 11 years, 9 months, 6 days including the landing date :)
