You can see the insides of a rock on Mars from this view. The Perseverance rover's drill was used to make the hole. The Perseverance rover took a close-up view of the hole after taking the sample.
Kevin Gill uses a technique called focus merge to get the best view. A "focus merge" uses a series of images taken at different focuses, stacks them up and uses whichever of the two is the best. There is a larger version on Kevin's website.
Gill said that it was called "Auto merge." It is possible that the rover does this onboard. I wrote my own method of computation.
The camera and drill are on the end of the robot arm. The sample from the rock is about the size of a thumb. The first sample from the Jezero delta is the 10th core sample taken by Perseverance. Evidence of past life on Mars may be provided by this region, which appears to be an ancient river Delta.
The first few rocks that were tested were found to be too rough to place the drill.
Skinner Ridge was the best candidate. After the first tests, it was time to core the rock.
Brockie wrote that it was the longest core of the mission so far. It was exciting to see that the same clasts were visible in the core.
With the proposed Mars sample return mission, which will bring back selected core samples that the rover has collected, the core sample may get a one-way ticket back to Earth.
The current area is named after the U.S. national park.
