The HiRISE team said: “Named after Eugène Michael Antoniadi, a Greek astronomer, Antoniadi is 394 kilometres in diameter, and once contained rivers and lakes.
“HiRISE has imaged numerous inverted channels in this crater.”
The picture was taken on May 10, 2018 when the MRO flew 173 miles (180km) over Mars.
There is a second Antoniadi Crater in the solar system located on our Moon.
Another of NASA’s MRO pictures shows a colourful “impact ejecta” or the material thrown out by a space rock impact.
