HiRISE Eyes Fresh Craters on Mars
Just to remind you that things are still indeed going “boom” in our Solar System, here is a cluster of fresh craters on Mars created by an impact that occurred sometime between 2008 and 2014.
The craters are a result of a meteorite that broke apart during entry, striking the surface as fragments within a localized area. The largest crater’s ejecta field spans about 100 meters across.
It’s kinda like Mars’ way of saying “how’s that space program coming along?”
The image, captured in infrared wavelengths by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter on Oct. 4, 2016, shows at least 20 individual impact sites. The craters were first discovered with a different camera, but this is the first image of them using HiRISE. See a map-projected view of the region here.

Also below is a look at likely an even fresher crater, which was created between May 2012 and Sept. 2016. Also captured by HiRISE, it’s about 200 miles away from where the now-silent rover Spirit is, with a central crater of 8 meters across but an ejecta field nearly 1 km wide. (Source)
