#Perseverance moved a little again. These days a simple detour around a regolith bump seems to be a real feat for the rover, and to take ages to plan and complete.
Oh, then… maybe that Visual Language Model, a.k.a. "AI" is involved again? That could explain the extreme caution of the operators that we are witnessing.
But that's just speculation. We've been living in the dark since the team's last report in December last year.

#Perseverance either drove into a dead end and is now surrounded by heaps of sand, or found something interesting there, which we don't see yet…

After a very long stay at Pine Pond #Perseverance has now moved further down hill, apparently reaching the bottom of the Witch Hazel Hill area, where it has spent the last 120 sols examining rocks.
The path shown is a guess. Elevations are from the Octavia E. Butler landing location.
The map was made in #QGIS, using #NASA's #MMGIS and #HiRISE and #USGS imagery and DTMs.

#Perseverance has now arrived at the area called Broom's Point.
Tosol is Sol 1435 of the #Mars2020 mission, Lₛ is 52.1, and the local time in Jezero Crater is now 18:21.

#Perseverance's 5th campaign, named Northern Rim, on the map (comes out being about 9km from Lookout Hill to Singing Canyon).
Now, if you call this part of *western* Jezero Crater 'northern', then it follows that there will also be a *southern* rim campaign in the future 😎

#Ingenuity would be easy to spot in an image if it occupied a few visible pixels, since the line-of-sight to the #MarsHelicopter passes right above the Mount Washburn group of hills, where #Perseverance had been 102 sols ago.

It looks like #Perseverance went for the bacon¹ 🙂
On Sol 1168 the rover moved to RMC 52.5032 across the ancient riverbed and stopped a few meters away from a light colored layer of rock at the foot of the northern bank, which appears to be the same layer with that of Bright Angel.
¹"the bacon strip": unofficial name for a light colored layer of rock back at the Three Forks area.

This Memorial Day added an interesting twist to the daily grind of #Perseverance 🙂 Not only did it clear the rest of the rego-ripples it had to the north, but took advantage of the holiday to go on a picnic at a nice hill to the northeast 😀 🙃. Apparently the hill has a geological story to tell and the team's geologists are eager to hear it.
The path is a wild guess.

Any idea where JPL have moved the Mars mission maps to? The old URL for M20 and MSL are broken. They have just reformatted a number of mission pages (raw images, home pages etc), but I cant find the new URLs for the maps...

New 30m drive and new location for #Perseverance on Sol 1114, RMC 51.2990, the closest so far to #Ingenuity, just 360m south of it, and very close to the edge of the south Neretva Vallis riverbank.

Finally on Sol 1063 #Perseverance did the right thing and backed off 23m to an area where it (most probably) has line-of-site to #Ingenuity, so more images of the #MarsHelicopter can be captured, especially images with its SUPERCAM telescope.
The previous location where Perseverance captured images of the Ingenuity is shown with a green rover.

Another sol, another drive for #Perseverance. The rover is approaching the northern edge of the rocky Margin Unit, getting closer to where #Ingenuity is located after its eventful #Flight72, but it still has no line-of-sight to the #MarsHelicopter. It may be in a better position for a first look in a sol or two, as seen in the visibility plot below.
The path shown is a guess.

Looks as if #Perseverance was hit by a meteorite; or its RAM was hit by a neutron; or (most probably) is looking for the right rock to have a drilling conversation (monologue) with 😬
New site number and RMC: 49.0000 on Sol 1019.

Any #RStats #GeoSpatial gurus out there familiar with using #NASA #MMGIS with #Leaflet? We have issues with Leaflet actually _rendering_ tiles from the the #Mars #M20 provider. We know it's doing the #slippymath and requesting the correct tiles, but they don't show.

This is what #Ingenuity saw from a 24m altitude when it flew its #Flight61 yestersol (if it did; no image confirmation yet)
Note: While NASA's announcements of #MarsHelicopter flights contain numbers seemingly "precise" to fractions of seconds or meters, they fail to correctly specify date/time (is it EST, PST, UT?) or Sol.

New location for #Perseverance on Sol 908: RMC 44.3978.
Initial estimate, based solely on metadata, has the rover about 280m to the west, descending to lower ground through a smooth opening on the edge of Mandu Wall, right on the planned route.
The path shown is just a guess.

#Ingenuity is about to take to the skies for its 43rd flight: https://mars.nasa.gov/technology/helicopter/status/439/flight-43-preview-by-the-numbers/. No indication if it'll be one-way or round-trip. Interestingly, the post gives distance to cover with two decimals precision, i.e. centimeters 🤔
The map shows two green circles: the inner one is the round-trip range and the outer the one-way range of ~377m, as given by the report, rounded to meters.

New location and path estimate for #Perseverance on Sol 700. The rover drove a distance of about 10m (white) through a "gate" clearing the ridge leading to the "bacon strip" plateau. It had used the same "gate" on its way down from that plateau, around Sol 538, last August. It's a ~30% slope that justifies the caution. My prediction for the next drive(s) is shown in green.

It looks like #Ingenuity flew its 42nd flight last Saturday, i.e. Sol 697; #NASA now shows flight path and landing on the #MMGIS map.
Apparently it flew above the same area it had previously scouted in its round-trip 41st flight, and then went NNW and landed very close to the guesstimate location. Dark areas are not visible by the #MarsHelicopter:

We've seen this place before.
New location estimate for #Perseverance on Sol 694 and RMC 32.2340. The rover covered about 186m of ground, and seems rather determined to reach its next target ASAP, judging from its (guessed) straight line track 😃
