The other day, detailed images of one of the Martian craters appeared on the Web, with a picture taken of a Mars Reconnaissance Orbiter, or more precisely, a HiRISE camera. This camera was created by Ball Aerospace & Technologies and cost the creators about 40 million US dollars.
Wikipedia tells us that “the camera is a 0.5 m aperture reflecting telescope. This telescope is the largest telescope sent into deep space. The camera resolution reaches 30 cm per pixel when it is at a height of 300 km above the surface of Mars. "

"People's" camera is named because the public can offer scientists areas of Mars for shooting. In other words, an ordinary person can become a member of a group that advises to take a snapshot of one or another part of Mars.
And HiRISE does not get tired to surprise both scientists and just fans of astronomy. The other day a snapshot of a crater with a diameter of 1 km was posted on the Web. This crater is located in the northern part of Sinus Meridiani. The crater is interconnected by the fact that it was formed on the conventional line of the junction of two types of Martian landscape.
The western side is aeolian deposits, basalt sand brought by the wind and laid on light rock. The eastern side is a depression filled with light material.

Of course, scientists still have to study this picture in detail, however, its scientific value is not subject to doubt. By the way, one pixel here is about 30 centimeters.
