NASA’s Mars InSight lander may have the first recording of a Marsquake
Here’s what a rumbling Red Planet sounds like
Let’s get ready to rumble: NASA may have just captured the first recording of an earthquake on Mars. On April 6, the Mars InSight lander’s seismometer recorded a short series of howls, grumbles and pings. One of those sounds — a grumble — is probably a Marsquake, representing the first recorded sound from the interior of the Red Planet, scientists say.
The recording, released by NASA April 23, lasts about 40 seconds. It begins with the faint, eerie howling of the Martian wind, followed by the low rumble of the possible Marsquake. A large ping toward the end is the spacecraft’s robotic arm moving.
