The stunning image above shows a new crater which was spotted by NASA’s Mars Reconnaissance Orbiter and taken with the probe’s onboard HiRise camera.
The hole is only about 30 meters (100 ft) in diameter – that’s smaller than an Olympic sized swimming pool, yet the explosion that generated the crater tossed out debris as far as 15 km (9.3 mi)! That’s enough to cover all of Central London – as shown below.
But this crater is nothing compared to the biggest impact crater on Earth. Vredefort crater in South Africa is the largest verified impact crater on Earth, which is more than 300 km across!
