A small space rock crashed into Mars, and NASA has captured a stunning view over the crater grave, as well as the track of an avalanche caused by the impact.
The new Mars crater was probably caused by a meteor impact in the past 10 years, NASA officials explained in an image description. NASA’s Mars Reconnaissance Orbiter (MRO)spotted in the crater of a job and the agency released the image on June 15.
“The crater itself is only 5 metres [16.5 ft] about to come, but the slash is the started is 1 kilometer long!” NASA officials wrote. “Slope streaks occur when the dry dust avalanches behind dark swaths on the dusty Martian hills. The faint scar of an old avalanche is also visible on the side of the new dark stripe.” [Latest Photos by NASA’s Mars Reconnaissance Orbiter]
The impact crater is small, but the traces that he left behind, as you can see in the image, is huge. If the meteor that caused this crater hit Mars, it disrupts the slope, it collided with that caused an avalanche of Mars dust, dirt and sand. This event left a dark stripe, which is known as a slope streak on Mars surface. And as NASA pointed out, you can still see the “scar” of an earlier avalanche in the area.

Attractions such as long, dark streaks on a Mars hill are not uncommon on the surface of the Red Planet. And researchers agree that these dark slope streaks are caused by dust avalanches.
The martian surface is covered with sand, dirt, and dust grains, and the planet is known for its storms and be hit by meteoroids. (A meteor is a small rock in space. When it is in atmosphere and ignites, it is known as a meteor. Only fragments that reach the surface are meteorites called.)
However, for years, scientists have pondered the origin of these brands. Previously, researchers suggested that these dark streaks can be caused by the transient, flowing salty water, perhaps indicating that Mars is habitable, as many suspect, over time. Researchers had thought that the underground water may rise to the surface, causing the dark streaks. This theory was supported in the MRO detected the hydrated salts in these stripes. Some even suggested that the streaks were caused by the seasonal carbon dioxide frost. However, a study published last spring in the journal Nature Geoscience points to avalanches as the main cause of the stripes.
MRO took this spectacular new impact crater image with the HiRISE High Resolution Imaging Science Experiment, which is manufactured by Ball Aerospace & Technologies Corp., Boulder, Colorado,and is operated by the University of Arizona. HiRISE has some of the most spectacular and detailed images of the martian surface to date.
NASA’s MRO spacecraft launched to Mars in August 2005 and came out in the beginning of 2006. It is the study of the Red Planet from space.
