NASA InSight lander records largest earthquake on Mars ever, scientists say
NASA’s InSight Mars Lander recorded the largest earthquake ever on Mars.
According to new research published in the journal Geophysical Research Letters of the American Geophysical Union (AGU), the international team said that on Earth’s night of May 4, the lander’s seismometer detected an earthquake at least five times the magnitude of an earthquake. second largest recorded earthquake. on the red planet.
“This was definitely the largest marsquake we’ve seen,” Taichi Kawamura, lead author and planetary scientist at the Institut de physique du globe de Paris, France, said in a press release.
Co-author and seismologist John Clinton, of the Swiss Federal Institute of Technology in Zurich, said the energy released by the single marsquake is equivalent to the cumulative energy of all other marsquakes observed so far.
Clinton, who is a co-leader with Kawamura on the marsquake service, said the waves recorded at InSight were so large they nearly saturated the seismometer.
The waves of the Marsquake last about 10 hours.
No previous marsquake wave had exceeded an hour in length.
The previous largest quake, recorded in August 2021, had a magnitude of about 4.2, while the earthquake in May had a magnitude of 4.7.
The epicenter of the earthquake was outside the most seismically active region on Mars.
This seismic event was also rare because it showed characteristics of both high and low frequency earthquakes.
Data from this major earthquake was released in October by the Mars Seismic Experiment for Interior Structure (SEIS), NASA Planetary Data System (PDS), and the Incorporated Research Institutions for Seismology (IRIS) data service, along with the marsquake service catalog.
Seismology on Mars can help researchers better understand what lies beneath the surface and its evolution.
It is believed that most marsquakes occur due to foul movements.
InSight is believed to be nearing its operational end as dust has gradually covered the solar panels and reduced its power.
“We are impressed that we had this very remarkable event almost at the end of the extended mission,” Kawamura said.
Based on the data collected from the marsquake“I would say this mission was an extraordinary success,” he continued.
“My strength is very low, so this may be the last photo I can send. Don’t worry about me though, my time here has been both productive and serene. If I can keep talking to my mission team, I will — but I’ll be signing off here soon,” Insight’s 25-30-strong team posted on the lander’s Twitter on Monday. “Thanks for staying with me.”
Since landing in November 2018, the lander has provided insight into Mars’ liquid core and the composition of the other inner layers. It has detected hundreds of earthquakes.
