Meteorites hit Mars and create small craters like the one we've imaged here. Usually we spot these new craters in lower-resolution images from the Context Camera because the impact disturbs dust on the surface and creates a dark mark that's much bigger than the crater. This meteorite hit a dusty area and made a crater, but did something a little more special to the surrounding dust. We can see dozens of dark, dust-free, streaks on slopes surrounding the crater. These slope streaks form when dust slumps downhill and happen naturally on a regular basis. In this case though, the impact and expl…
