#Perseverance moved to a new location close by. The image shows my prediction for its next target (ellipse).

EDIT: Updated map, but it looks like it needs some CRS work after my recent change to the new #HiRise imagery.

Circular agricultural structures near Tabarjal, in the barren desert of northern Saudi Arabia.

The circles, each approximately one kilometre wide, are formed by central-pivot irrigation systems. These consist of a well at the centre of each circle, which supplies water from underground aquifers to rotating sprinklers. This type of irrigation helps farmers manage water in a more sustainable way to conserve this precious resource.

It may have moved, but Perseverance rover managed to abrade some of the targets weathered surface for further investigation. Here's two images from Sol 1567 (July 17, 2025), a processed NavCam tile (for context), and a close-up of the patch from the SHERLOC WATSON camera (mounted on the turret next to the drill). For scale the patch has a diameter of about 2 inches (5 cm) - Credits: NASA/JPL-Caltech

Pushing a rock around on Mars! Time lapse from Perseverance Rover's HazCam (timestamps included). Watch closely, to see the movement of the shadows from the robotic arm, the rock, the sand grains, the drill mechanism, and the dust all moving around. Animation of 15 images taken about 1 minute apart, the duration was about 13 minutes on sol 1565 (July 15, 2025).

@PhilStooke
Canals existed on Mars not when people imagined seeing them in the early days of telescopes, but in the 22nd century.

In a strange perturbation of time, as it frequently happens when #SciFi is involved, one of #NASA's Human Exploration of Mars Science Analysis Group (HEM-SAG) proposed landings near crater Pendicton was just 365 km away from the exit of the Soletta Canal, which was burnt into the ground by a huge orbiting mirror made from reflective solar sails.

Whether illuminated by daylight or artificial light, if those were on Earth, I'd swear they were lichens… But, IANAG™, and IANAB™ either.

"The reason why is utterly moronic:

[A] Starship mission to Mars has an 82.6% chance of ending in a giant fiery explosion far closer to Earth than Mars.

With the current huge underperformance in payload, which is unlikely to be resolved anytime soon, it will take at least 33 refueling missions before Starship can head for Mars.

[A]t the current rate of Starship launches, this refueling process would take roughly eight years."

"[W]e can expect even worse dick-swinging to come, because Bezos’ Blue Origin has now been predicted to eventually beat Musk’s SpaceX to Mars.

It’s now an open secret that this upcoming test flight will carry NASA’s ESCAPADE mission to Mars, with the mission expected to enter Martian orbit by 2027."

Huh?!

A pair of SUPERCAM images in a pseudo-3D setting for cross-eyed viewing. The small parallax doesn't offer much of 3D depth.

The little 1.5cm pebble is about 2.8m from the camera (2m horizontal distance), yet another of those #JezeroBrightRocks that #Perseverance keeps a record of.
