NASA Mars lander picks up remarkable 1.5-hour-long marsquake

InSight has been feeling some good, good, good vibrations on the red planet.

This story is part of Welcome to Mars, our series exploring the red planet.

NASA’s Mars InSight lander had two big reasons to celebrate on Sept. 18. It marked the lander’s 1,000th Martian day (called a «sol») on the red planet, and it’s also the day it detected a fantastic nearly 1.5-hour-long marsquake estimated to hit a magnitude of 4.2. Talk about shaking things up.

It’s been quite a run of marsquakes for InSight lately. It also picked up quakes of magnitudes 4.1 and 4.2 on Aug. 25. All three of these recent shakers beat out the lander’s previous record holder for magnitude, a 3.7 picked up in 2019. As NASA JPL pointed out in a statement on Wednesday, a 4.2 quake has five times the energy of a 3.7.

Marsquakes tell a story. «The waves change as they travel through a planet’s crust, mantle, and core, providing scientists a way to peer deep below the surface,» NASA said. «What they learn can shed light on how all rocky worlds form, including Earth and its moon.»

InSight landed on Mars in late 2018 and deployed its seismometer in December of that year. The lander’s stationary status might make it seem less compelling than its wheeled rover kin, but the mission has revealed lots of new information about mysterious Mars.

A group of studies released in early 2020 used InSight’s data to paint an intriguing picture of an active Mars underground. InSight established, without a doubt, that Mars is a seismically active planet. Another outpouring of studies from earlier this year showed how scientists could use InSight’s work to map the interior of another planet for the first time.

InSight’s recent marsquakes detections are a triumph for another reason. A thick layer of dust on the lander’s solar panels put the mission in a precarious position. NASA was expecting a whirlwind to come along and clean them off, but that hasn’t happen. To keep the lander operating at a high level, the InSight team came up with a clever way to clean some of the dust off by dribbling a bit of dirt onto the panels. It worked.

Scientists are still studying the most recent quake, but they’ve already figured out that the 4.2 quake from August came from 5,280 miles (8,500 kilometers) away, making it the most distant marsquake yet detected by InSight. The 4.1 originated from a mere 575 miles (925 kilometers) away.

The latest marsquakes data will help build our understanding of the interior of Mars. We know for sure the red planet is giving itself quite a few fair shakes.

Resident Evil Requiem Revealed, but Where’s Leon Kennedy?

The Resident Evil 9 trailer showed off a new character, but not the much-rumored return of Leon.

After a fake-out earlier in Summer Game Fest on Friday, Resident Evil Requiem, or Resident Evil 9, was shown for the first time.

The new title is the first mainline entry since Capcom released Resident Evil Village in 2021, and is rumored to feature series stalwart Leon Kennedy. In the trailer, the only person we saw was a character named Grace Ashcroft, who works for the FBI and appears to have ties to Raccoon City.

For the most hardcore Resident Evil fans, the name Ashcroft will ring a bell. Alyssa Ashcroft was one of the survivors of the online-only title, Resident Evil Outbreak for the PS2. Alyssa was a journalist who was trapped in Raccoon City during the events of Resident Evil 2, and she, along with other survivors, had to escape the city before it was destroyed.

Grace is Alyssa’s daughter, and in the trailer, she is going to visit the Remwood Hotel, where Alyssa was murdered. Later in the trailer, images from what appears to be the remnants of a destroyed Raccoon City are shown — including the police department from RE2 — so it appears Resident Evil 9 will return to where the series started.

Leon’s (rumored) return is a big deal for the series, which has made some of its best games with him in the starring role. He first showed up as a rookie cop in Resident Evil 2, which built on the original game’s success with more story and improved monsters and level design.

He showed up again in Resident Evil 4, which took the series in a new direction by introducing an over-the-shoulder perspective, instead of the usual static camera angles and tank controls. Leon was also one of several playable protagonists in Resident Evil 6, a game that seemed to forget about its survival horror roots. We mostly don’t talk about that one.

But the 2019 remake of Resident Evil 2 was an excellent return to form, bringing RE4’s gameplay and much better graphics to a fan-favorite entry. The RE4 remake was a similar success.

Resident Evil Requiem is set to drop Feb. 27, 2026, for PC, PS5 and Xbox Series consoles, but we’re hoping to get our hands on it this weekend. If you want to catch up on older Resident Evil games, Capcom is having a sale that includes basically all the games, including Village and the three remakes.
