Almost there. RMC 52.0870.

seems to be determined to reach Bright Angel as soon as possible, even if it has to do it in short drives every sol, through rocky ground.

If the does take an RTE picture every Martian morning as stated, then it will most probably capture the rover as it descends slowly the slope of Neretva riverbank. The only question then is when we will see those images.

This one on Sol 1019 appears to have been another one where AutoNav had a hard time finding its way, but also had RIFMAX ops planned.

Inching closer. Another ~70m to go and, maybe, will check to see if is still functioning, by taking a couple of RTE images, and hopefully have it get a last glimpse of before it disappears below the horizon.

And, don't say the rover has turned its back on little , even if it appears to be so in the image. For it has a duty, and a long mission still ahead. Say, hasta la vista lil'sis!

zoomed in on what appears to be the path forward on its way to Bright Angel. That area at the center where slope increases is approximately where the rover will enter the field-of-view of 's RTE camera, about 150m W from its current location.

What's really exciting about the drive down the slope of the Neretva riverbank is that at some point along the way, maybe within a week or two from now, the rover will be visible by 's RTE camera, at the top right corner of an RTE image, as seen in this graphic by @stim3on where I marked a possible appearance with "future Perseverance".

is on the move again, and this time it's made its plan unambiguous: onward to Bright Angel!

Here starts a torturous trek down the ancient Neretva riverbank, to be followed by a crossing of the sandy and flat(ter) riverbed, and finally the arrival at Bright Angel, maybe by late summer.

This image shows the actual inclination of the ground at RMC 52.0130, the current location of on Sol 1131, and, maybe, why the trip to Bright Angel down the ancient riverbank and into the sandy Neretva riverbed might be risky.

Which way to go?
White route leads to Bright Angel.
Green route leads inland and eventually upward toward the cater rim. The photo shows the (guessed) start of the green route.

So, where is the when you need it?
