    Images Mars
In summary, the conversation discussed various images from NASA's Mars Reconnaissance Orbiter, including a close-up of a trough and a cutout from CTX 033783_1509 which showed an impact crater and a collapse depression. The formations seen in these images were described as resembling glacial crevasses and bedforms resulting from fluid flow.

Who's got some ideas?

This image from NASA's Mars Reconnaissance Orbiter is a close-up of a trough, along with channels draining into the depression. Some HiRISE images show strange-looking formations. Sometimes it helps to look at Context Camera images to understand the circumstances of a scene -- like this cutout from CTX 033783_1509 -- which here shows an impact crater with a central peak, and a collapse depression with concentric troughs just north of that peak.

the right ones remind me of glacial crevasses .. but no glaciers here

Definitely weird

This ridges appear to be a classic example of bedforms. which result from fluid flow over sand or similar aggregates. Note how they tend to align perpendicular to 'walls' of the canyon in which they reside.

What is HiRISE?

HiRISE (High Resolution Imaging Science Experiment) is a camera on board the Mars Reconnaissance Orbiter, a satellite orbiting Mars. It is designed to capture high-resolution images of the Martian surface.

What do the strange-looking formations in HiRISE images represent?

The strange-looking formations in HiRISE images are geological features on the surface of Mars. These features can include mountains, craters, canyons, dunes, and other formations created by geological processes on the planet.

Why are the formations in HiRISE images important?

The formations in HiRISE images provide valuable information about the geology and history of Mars. By studying these formations, scientists can better understand the processes that have shaped the planet and how it has changed over time. These images also help in identifying potential landing sites for future missions to Mars.

What causes the formations in HiRISE images to look strange?

The formations in HiRISE images may appear strange due to a combination of factors such as lighting, composition, and perspective. The images are taken at a high resolution, which can reveal details that may not be visible in lower-resolution images. Additionally, Mars has a complex geological history, which can result in a variety of unique and interesting formations.

How are HiRISE images captured and processed?

HiRISE images are captured using a telescopic camera that can take photos in visible and infrared light. The images are then processed and enhanced by scientists to improve the contrast and color to better reveal the details of the Martian surface. The images are also stitched together to create a larger and more detailed view of the area being studied.
