InSight’s Spectrogram of Big Martian Quake: This spectrogram shows the largest quake ever detected on another planet. Estimated at magnitude 5, this quake was discovered by NASA’s InSight lander on May 4, 2022, the 1,222nd Martian day, or sol, of the mission. Credits: NASA/JPL-Caltech/ETH Zurich.

Mars science discoveries can be so superficial — the search for water caches, terrestrial sampling, and other technical marvels tend to take place on the surface of the Red Planet (or a little above it). But while NASA’s Perseverance rover scoots around in Mars’s dust and gravel, there’s plenty deep within the planet itself that’s … Read more
NASA‘s InSight lander has measured one of the biggest and longest marsquakes yet, which featured tremors of 4.2 magnitude lasting nearly an hour and a half, the space agency said. The robotic seismometre celebrated 1,000 days on the Red Planet on September 18, when it detected the largest tremor since it arrived at the Elysium … Read more
After succeeding in a bold attempt to brush dangerous amounts of dust from its solar panels, NASA’s InSight Mars lander has hit two major milestones: 1,000 sols (Mars days) on the surface, and the detection of the three largest marsquakes ever recorded. Earlier this year, says the mission’s principal investigator, Bruce Banerdt of NASA’s Jet … Read more
Scientists successfully give InSight Mars lander Power Boost to continue mission in Aphelion Just as earthquakes occur on Earth, marsquakes occur on Mars. Quakes vary in appearance and feel according to the material through which their seismic waves flow. Whether these marsquakes will have an effect on human colonisation in the future remains a challenging … Read more
The lander cleared enough dust from one solar panel to keep its seismometer on through the summer, allowing scientists to study the three biggest quakes they’ve seen on Mars. On Sept. 18, NASA’s InSight lander celebrated its 1,000th Martian day, or sol, by measuring one of the biggest, longest-lasting marsquakes the mission has ever detected. … Read more
WASHINGTON (Reuters) – Seismic waves from quakes detected by NASA’s robotic InSight lander have helped scientists decipher the anatomy of Mars, including the first estimates of the size of its large liquid metal core, thickness of its crust, and nature of its mantle. The findings disclosed on Thursday shed light on what had been a … Read more
The interior structure of Mars. Credit: NASA/JPL-Caltech. The InSight lander on Mars has detected hundreds of marsquakes, including a few large quakes with strong detections of both P (pressure) and S (shear) waves. Shear waves vibrate perpendicular to their direction of motion like ripples on water, but they do not pass through liquid and pass poorly through … Read more
