Here is why the core has to be deep inside the tube: the cap has substantial size to ensure that the seal will withstand the harsh environment of Mars, the vacuum of space, reentry in Earth's atmosphere, and landing.

And… we have cigar!

in the shape of a new rock sample () from the rock had abraded recently and just cored as a present to herself for her own "birthday" tomorrow, when she becomes 4 years old on Mars 😍

@PaulHammond51
It may be small and ugly, but that is definitely a piece of rock in there. And the tube is capped and sealed, which makes it (animated image below).

Yesterday @PaulHammond51 noticed the difference in the color of tailings from the "Apollo Temple" abrasion (thanks for the name @JoseAC !) and the drilling for the new sample. Here is a better image showing them both:

This animation superimposes an image of the surface of the rock with the on one of the bottom of the rock sample in the sample tube, suggesting possible similar patterns through the body of the rock sample.

Apparently had another go at rock Bunsen Peak, and this time it succeeded in getting a core. The proof is in the images.

For a 100% successful sample acquisition, the sample has to be measured and the tube capped & sealed before being stashed along with the other samples inside the rover's belly.

Images from Sol 1086 show us that the rover acquired a fractured core, but it appears as though it was lost during transfer to the imaging station (MastCam & CacheCam) Credits: NASA/JPL-Caltech/ASU/MSSS

The last step in the process of acquiring a rock sample: visual proof that the sample is capped and sealed. Then it goes for safekeeping in 's belly.

acquired, capped and sealed a new sample, all in one go, late in the night on Sol 923.

Here is an animation of 20 CACHECAM images with the sample in the measuring station, and after being capped and sealed, played at 5 fps.

had been silent about its rocky business lately, but it has now appeared with a new core in its hollow drill bit:

It appears capped and sealed the last sample tube yestersol, Sol 913.

Meanwhile, is coring that Mount Meeker rock, next to the Dragons Egg abrasion. Here is how it was going, a few hours ago:

Look at this big chunky weirdo. 🪨 I love it.

I spotted this boulder from a distance and have come in for a closer look. It’s harder than most, with an odd shape and makeup. #SamplingMars could be a challenge here, but I’m up for it!

It seems like only "yestersol" since I last saw my original landing site. The two rock cores I collected there in March 2022 capped my exploration of the crater floor, and are unlike any I’ve collected since while #SamplingMars. Learn what makes these two samples so interesting:

One thing I’m #SamplingMars for is organic molecules, the “building blocks” of life. The rock I got these two samples from has signals suggesting they may be present. Signs of biology, or another process, maybe? Hear why scientists would love to study sample #6 or #7 up close:

Spot the “polar bear!” One rock that @NASAPersevere drilled while #SamplingMars had an odd-shaped crystal inside – a mineral that on Earth is good for preserving signs of ancient life. See why one of this rock’s samples could be fascinating to bring to Earth by #MarsSampleReturn.

abraded the rock Ypsilon Lake at about the same spot it had cleared a couple of sols earlier, called Lake Helene.
