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.

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.
New location for #Perseverance on Sol 1156, after a rather short ~16m drive downhill, which brought the rover 2m lower, to RMC 52.2750. There is now a ~10m remaining vertical distance to be covered to the bottom of the riverbank and onto the ancient riverbed of Neretva Vallis.
#Perseverance drove 10m on Sol 1150, to RMC 52.2638. As mentioned earlier, this appears to be the most difficult part of the descent to the ancient riverbed of Neretva Vallis, on the way to Bright Angel, a rock formation of geological interest.
The maps were drawn with @QGIS, using data from #NASA's #MMGIS, imagery from #HiRISE and DTMs from #USGS
New location for #Perseverance on Sol 1144, RMC 52.1950.
This may be the last location visible by #Ingenuity's RTE camera, as the rover has now reached the theoretical limit of its field-of-view (cyan line). The #MarsHelicopter has been programmed to capture one RTE image every sol for as long as it is able to wake up every sol perform its routine of gathering environmental and system data, as a stationary testbed.
New location for #Perseverance on Sol 1143, RMC 52.1700, presumably still within #Ingenuity's field-of-view. It appears there may be as many as 3 frames of the rover crossing the FOV of the color RTE camera of the #MarsHelicopter, now a stationary testbed collecting images, temperature and other data on a solly basis from its final location at Vallinor Hills.
#Perseverance moved to the center of the area which is most probably visible by #Ingenuity, and it could appear in one or more of the color RTE images the #MarsHelicopter is capturing every sol, if everything is going according to plan.
#Perseverance 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 #MarsHelicopter#Ingenuity 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.
New location for #Perseverance on Sol 1136, RMC 52.0606. If all goes smoothly, in two more similar drives the rover will be entering the field-of-view of #Ingenuity's RTE color camera, and Perseverance's team will have their last and only opportunity to have a picture of the rover captured from the ground of Mars, at least for the foreseeable 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.
#Ingenuity is visible, and will be so all the way down to the riverbed.
'The methods used to collect, interpret, and disseminate map data have been evolving ever since [Hawaiian Volcano Observatory's] founding in 1912, and a digital tool newly available to the public continues that legacy of innovation. The new digital tool is an interactive, browser-based display of map data that can be updated in near-real-time with eruption features, such as lava flows.'
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.
#Perseverance moved another ~40m to SW to RMC 51.2390, inching closer to the area where it will again have visibility to #Ingenuity (green on the map). The path shown is a guess.
EDIT: Updated map. New images coming in show that the rover moved further south to avoid some difficult to drive through terrain.
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.
The United States Geological Survey usually detects anywhere between 20 to 50 earthquakes, 2.5 or higher in magnitude, globally, on a daily basis.
In the last 24 hours, there have been no less than 145 earthquakes of this caliber.
