NASA’s InSight Mars lander detects 3 biggest marsquakes to date

NASA’s InSight lander has detected its three most powerful marsquakes yet, potentially giving scientists an even clearer picture of the Red Planet’s interior.

InSight spotted 4.2- and 4.1-magnitude temblors on Aug. 25, then picked up another roughly 4.2-magnitude quake on Sept. 18 that lasted for nearly 90 minutes, NASA officials announced on Wednesday (Sept. 22).

The previous record holder, which InSight measured in 2019, clocked in at magnitude 3.7 — about five times less powerful than a 4.2-magnitude quake.
