ANU astrophysicist and cosmologist Dr Brad Tucker says the largest quake ever – a magnitude 5 quake – has been recorded on Mars.
“Mars quakes have been monitored now for about a couple years, since NASA’s Insight mission landed in 2018,” he told Sky News Australia.
“We’re starting to find a lot of interesting things, so we found a lot of these Mars quakes but most of them are weak, magnitude 3 or 4.”
Dr Tucker said the quakes are expected to get bigger and this quake was “quite sizable”.
“This is going to interesting for not just understanding the history of the planet because we want to know is it active underneath Mars’ surface, why is it apparently less active than earth, and this tells us a lot about potentially what is underneath,” he said.
