Curiosity Rover's robotic arm workspace on mission sol 4554 (May 30, 2025) after a drive to the south-southwest of ~29 meters (~96 ft) and a climb of 2.6 meters (8.6ft). The mosaic was assembled from 15 overlapping Bayer-reconstructed L-MastCam sub-frame images. NASA/JPL-Caltech/MSSS/fredk.

What would be more appropriate for the summer solstice than a picture of the Sun itself?

Looks as if #Perseverance was chased out of Krokodillen by a dust devil 😀 🙃, but outran it!

Summer solstice coming up in 7 ½ hours, in the northern hemisphere of Mars (i.e. when Lₛ → 90°, now at 89.81°).

Watch it live 😎 🙃 along with #Perseverance and #Ingenuity¹ (which is presently watching sand shift in the light summer breeze at the Valinor Hills beach), with Mars24, a Java program by #NASA, based on equations by Allison and McEwen:

#NASA's #MMGIS has moved (probably some time ago) to a new dataset prepared by the #USGS which includes areas west of Jezero Crater, which may be where the Mars Sample Return mission (#MSR) could land, if the mission ever takes off.

For those interested in Martian maps and #GIS, here is where to find the new data:

Guillotine

Unknown use on Mars; last used in France in 1977, to execute a child murderer. No, #Netanyahu is alive and wanted by the #ICC for murdering thousands of #Palestinian children and other #warCrimes.

#MarsPoetica

Speaking about the University of Arizona, home of #HiRISE, the High Resolution Imaging Science Experiment in Mars orbit:

"We believe that HiRISE is an intersection between science and culture. We often post lines of poetry, aphorisms and literary quotations in different languages […] paired with an image that is meant to show that Mars can also be a place of inspiration and reflection."

#Perseverance appears to be ready for some close examination of the bedrock at its new location at RMC 74.0000.

As with every change of site number, i.e. when drive numbers are reset to 0000 and the x, y, z data zeroed, localizing the rover is more difficult. Here I've done it by manual triangulation, using NAVCAM_RIGHT images whose center lines are seen on the map.

Used #QGIS to draw the map, with data from #NASA's #MMGIS, #HiRISE and #USGS
