It is this mountain, or in this direction.

@pomarede
According to the ChemCam RMI azimuth, it should be in this direction.

If I understand correctly, these are epically long, long-distance images, taken by Curiosity with her RMI telescope, in her attempt to capture a crater 91 kilometers away

ℹ️ see post by Abigail Fraeman science.nasa.gov/blog/sols-455

The intent is to compare the long-distance view from the ground with HiRISE orbital images in an attempt to create a 3D view.

After a decade of searching, NASA’s MAVEN (Mars Atmosphere Volatile Evolution) mission has, for the first time, reported a direct observation of an elusive atmospheric escape process called sputtering that could help answer longstanding questions about the history of water loss on Mars.

Perseverance dnes 29.5.2025 / sol 1519 pokračovala v další cestě. Jela 92 minut východním směrem, během kterých ujela vzdálenost 137 m a do kopce vystoupala 28 m. První snímky z nového místa byly pořízené předními kamerami HazCam ve 12:08 UTC / 13:09 LMST.

Two galaxies seen in a 'joust' preceding a cosmic mega-merger

At the heart of one of the galaxies resides a quasar. The intense radiation unleashed by the quasar is seen disrupting clouds of gas and dust, known as molecular clouds, in the other galaxy.

When searching for habitable worlds around other #stars, we must occasionally pause and appreciate the wonderful living organisms of our own #planet.

Nestled in the rocky terrain of La Silla Observatory in Chile, an unexpected guest is paying the ESO 3.6-metre telescope a visit.   Despite its excellent camouflage, the fuzzy face and pointed ears are a dead giveaway for the presence of a Culpeo Fox, who seems to be basking in the warm sunlight of the Atacama Desert. These ‘foxes’ are technically more closely related to wolves than to other foxes, and they can be found in many of South America’s most mountainous regions.  Clearly, this particular Culpeo has a passion for astronomy, since our furry friend has parked itself in front of a significant piece of ESO’s history. The ESO 3.6-metre telescope in the background saw first light back in 1976, and through consistent upgrades still finds itself at the forefront of astronomical research. Specifically, this telescope hosts one of the most successful exoplanet-hunting instruments ever — the High Accuracy Radial velocity Planet Searcher (HARPS).  Much like how the Culpeo uses its enhanced senses to hunt for rabbits, or other snack-sized animals, the ESO 3.6-metre telescope uses HARPS to scour the cosmos for new exoplanets. This instrument carefully measures wobbles and irregularities in the motion of stars, implying the presence planets through the effects of its gravity on the star’s orbit. These two hunters might well be at the top of their game, but right now it seems that both are taking a well-deserved rest. Credit: F. Murgas/ESO

Mars Guy Episode 216:

Curiosity Rover enters bizarre terrain.

Nearly two decades after they were first discovered, the Curiosity rover has begun to explore web-like features known as boxwork structures. Answers to how they formed and why they’re bigger than any on Earth are now emerging.
