One powerful tool in that impact hunting toolkit is the Mars Reconnaissance Orbiter (MRO). It has a variety of instruments on it that make it possible to both track down areas of interest and then follow up with high resolution imagery, incluidng HiRISE, the camera that took the picture above. That is exactly what happened with a new crater that the satellite noticed on one of its flybys.
The new crater shows up as a bright spot, which scientists theorize might be shallow subsurface materials that were blasted into the open on impact. This contrasts with many new craters, which show up as dark spots as dust from the ejecta is covered in a darker material. Those bright spots are significantly bright in the attached image though, as it was color enhanced in post processing.

The new crater is 13m in diameter, and shows up spectacularly on the newly released image. It goes to show just how active our solar system still is, and how a little rock can make a big impact when there's little to nothing to stop it.
