Older models of Mars assumed a liquid metal core beneath a solid mantle of silicates, but recent studies indicate that structure is missing at least one layer. Using data from the InSight lander's seismometer, two teams independently calculated that a liquid silicate layer must surround the planet's core. (Image credit: Mars - NASA/JPL-Caltech/University of Arizona, illustration - J.

There's also the ongoing question of life on Mars. Scientists think that liquid water lakes might be present below the surface. They also very much might not be, but if they are, they would require some sort of heating source to maintain a habitable temperature. The presence of magma would do it.
Rumbles detected deep inside Mars have promoted speculations over volcanic activity on the red planet from "possible" to "likely".
After studying a cluster of marsquakes detected by NASA's InSight lander, researchers have concluded that molten magma is probably still present beneath the crust of Mars â meaning that the surface of Mars continues to be shaped by volcanism to this day.
It's the latest in a series of clues pointing to volcanic activity persisting on Mars long after it was presumed to have fallen silent.
Don't mind me, just staring into the void trying to process the word "marsquake", because of fucking course. WHAT ELSE WOULD AN EARTHQUAKE ON MARS BE CALLED. I love language
So the story was, that Mars having long lost itâs molten interior and atmosphere, was now a dead world.Â
Well, itâs not quite as dead as was thought ! NASAâs Insight probe has detected 174 Marsquakes over the last 10 months, some as much as 4 on the Richter scale.
Insight will continue to map the seismic activity and give a better picture of what is actually going on below the surface. Â

âMarsquakesâ could help scientists learn more about the Red Planetâs inner activity.
Letâs get ready to rumble! NASA appears to have just captured the first recording of a quake on Mars. On April 6, the seismometer on the Mars InSight lander recorded a short series of howls, grumbles and pings. One of those sounds â that grumble â is raising suspicions. Itâs the first recorded sound from the Red Planetâs interior, and scientists say itâs likely a long-sought quake.
NASA released the 40-second recording on April 23, 2019. It begins with a faint, eerie howling of the Martian wind. Next comes the low rumble of the possible Marsquake. A large ping toward the end is the spacecraftâs robotic arm moving.
Explainer: Seismic waves come in different âflavorsâ
InSight landed on Mars in November 2018. Its mission is to probe the Red Planetâs interior. InSight does this by tracking seismic waves rippling through the ground. Mars lacks Earthâs powerful quakes, which are caused by shifting tectonic plates. But as the planet cools and contracts, it has smaller quakes, crackles and rumbles.
Scientists hope that InSightâs data will reveal Marsâ internal structure. That includes the size and density of its crust, mantle and core. Some of these data also might detail how heat flows through the planetâs insides as well as uncover hints of water there.
This new recording isnât long enough to provide much insight about the Martian interior, scientists say. But it shows Mars is seismically active. It also kicks off a brand-new field of research: Martian seismology.
This is what a marsquake sounds like. A seismometer on the planet picked up three different sounds. That initial howling is Martian wind. The low grumble that follows is a possible Marsquake. Finally, the ping is the spacecraftâs moving arm.
