Hypnotic animation shows how seismic waves spread across Mars months after NASA's InSight Lander recorded earthquakes on the red planet for the first time.
- NASA announced in April that the InSight lander had recorded its first Marsquake with its SEIS instrument.  According to NASA, tremors on different planets behave differently, depending on which material they need to travel.
- Scientists compared the Martian data with data from quakes recorded on Earth and on the Moon to simulate them.
Scientists have simulated the path of seismic waves across the red planet
The way earthquakes look and feel Depends on the materials they pass through, which means they may behave very differently What we are used to here on Earth is explained by the Space Agency.
A new animation shows how this could happen under the surface of Mars.

WHAT MAKES INSIGHT'S SEISMOMETER?
With the seismometer, scientists can look into the interior of Mars by studying the ground movement – also known as Marsquakes.
Every Martian earthquake acts as a kind of flash that illuminates the structure of the planet's interior.
By analyzing the passage of seismic waves through the layers of the planet, scientists can derive the depth and composition of these layers.
The new simulation comes from a team from the Swiss Research University ETH Zurich that uses data from the Apollo era, seismometers on the moon, earthquakes recorded on Earth and two Marsquakes recorded by the Seismic Experiment for Interior Structure (SEIS) instrument ,
According to NASA, however, the earthquakes were extremely weak.
& # 39; Researchers Need to Amplify Marsquake signals a factor of 10 million to sense the quiet and distant tremors compared to the similarly amplified moonquakes and unextended earthquakes. "InSight has measured a seismic signal in a recent release and recorded 6 – its 128th Mars Day.
While other disturbances were recorded, it is believed that earlier signals were caused by activities above the surface like wind.  However, the alleged Marsquake, known as Marsian Sol 128, seems to have come from the depths.
InSight's efforts build on the work of Apollo astronauts on the Moon in the late 1960s and 1970s, which for the first time revealed clues to the seismic activity of the Moon and the interior of the Moon.
Similarly, it is hoped that the seismometer measurements will help to improve our understanding of the events deep inside Mars.
While other disturbances were recorded, it is believed that earlier signals were caused by activities above the surface like wind. The lander is pictured up in December.
The team said the first seismic event was too small Gather solid data on this front, but they expect it to be only the first of many.
& # 39; The Mars Sol 128 event is exciting because its size and longer duration match the profile of the moonquakes that were detected during the Apollo missions on the lunar surface. "said Lori Glaze, director of the Planetary Science Division at NASA headquarters.
A robot stationed on the red planet has first discovered what a "Marchquake" is.
The scientists InSight al So detected seismic signals on March 14 (Sol 105), April 10 (Sol 132) and April 11 (Sol 133).
These were smaller and were more sensitive NASA and scientists are still working to determine their causes.
But the larger Sol 128 event seems promising so far.
"We have months on a signal like this serviced, "said Philippe Lognonn é, head of the SEIS team at the Institut de Physique du Globe de Paris (IPGP) in France.
"It's so exciting to finally prove that Mars is still seismically active," says the researcher. We had the opportunity to analyze it.
INSIGHT'S THREE KEY INSTRUMENTS
The More Information on the Origin of the Earth: InSight Landing for Mars Landing on November 26
With three key instruments, the InSight lander can measure the pulse of the Red Planet:
Seismometer : The InSight lander carries  Seismometer SEIS, listening to the pulse of Mars.
The seismometer detects the waves that travel through the inner structure of a planet.
The study of seismic waves tells us what the waves could produce.
On Mars, scientists suspect that the perpetrators may be Marsquakes or meteorites beating the surface.
Heat Probe: InSight's HP3 heat flow sensor digs deeper than any other blades, drills, or probes on Mars.
It is investigated how much heat still flows from Mars.
Radio Antennas: Like Earth, Mars wobbles a little as it turns around its axis.
To investigate, two radio antennas that are part of the RISE instrument closely track the lander's position.
This helps scientists to test the planet's reflections and explains how the deep internal structure affects the planet's motion around the sun.
