Using its High-Resolution Imaging Science Experiment (HiRISE), the spacecraft photographed the new feature on 17 April 2019 from an altitude of 255 kilometres (158 miles), according to a HiRise press release.
The crater is located in the Valles Marineris region near the equator, and it formed at some point between September 2016 and February 2019.
We can’t yet monitor the entire Martian surface at shorter intervals, hence the uncertainty as to when it formed.
The HiRise release described the new photo as a “work of art,” saying “the darker material exposed beneath the reddish dust” is what makes this particular crater stand out.
The bluish areas in the false-colour image above show areas in which the red surface material was most disrupted by the impact.
HiRISE team member and University of Arizona staff scientist Veronica Bray told Space.com that the crater is about 15 to 16 metres (49 to 53 feet) wide.
