NASA lander records massive 90-minute Marsquake in third major tremor in a month
NASA's InSight lander has measured one of the longest marsquakes yet, which had tremors of 4.2 in magnitude and lasted nearly an hour and a half.
The lander has been on the red planet for 1000 days and the tremor was the biggest recorded by the craft since it first arrived in 2018.
This magnitude equals the largest ever recorded on Mars, but on Earth, it wouldn't be considered much as more than 10,000 of that level are detected every year.
It was the third major quake in a month and it isn't clear whether there have been large ones and they have gone undetected.
NASA launched InSight to study the seismic waves and learn more about the red planet to better understand how it formed.
The waves change as they travel through a planet's crust, mantle, and core, providing scientists with a way to peer deep below the surface.
InSight relies primarily on solar power to keep it going, and earlier this year Mars' highly elliptical orbit took it further away from the sun and lowered temperatures.

The team behind the lander were very clever in how they managed the dust build-up. They trickled sand on one solar panel to shift some of the dust which ensured the lander stayed turned on throughout the summer months.
Mars is approaching the Sun again so the power will begin to recharge.
InSight's principal investigator, Bruce Banerdt of NASA JPL said: "If we hadn't acted quickly earlier this year, we might have missed out on some great science,"
