NASA Just Recorded a Quake on Mars: U.S. Space Agency NASA’s robotic Mars Insight Lander has recorded the possibility of entering “Marsquake” for the first time. The unconscious seismic signal detected by the Seismic Experiment for Interior Structure (SEIS) use of the instrument was recorded on April 6, at 128th Martian Day in Lander. NASA said in a statement that this is the first recorded trembling that came from inside the planet, as it is due to the powers above the surface. Scientists are still investigating the data to determine the exact cause of the signal.
“The first reading of the insight runs on the science that began with NASA’s Apollo mission,” said Insight Principal Investigator Bruce Banerdt of NASA’s Jet Propulsion Laboratory (JPL) in the U.S. “We are collecting background noise till now, but this first incident officially kills a new area: Martian seismology!” Mr. Banerdt said.

The new seismic event was too small to provide solid data on Martian Interior, which is one of the main objectives of Insight. Martian’s surface is extremely quiet, allowing SEIS, Insight’s specially designed seismometer, unconscious rumble.
On the contrary, Earth’s surface is continuously separated from seismic noise created by oceans and seasons. In Southern California, an event of this size is lost between dozens of small cracks daily. Lori Glaze, director of the Planetary Science Division at NASA headquarters, said, “Martian Sol 128 event is exciting because its size and long duration are fit according to the size of the moon found on the surface of the moon during Apollo missions.” For the latest updates, you can visit www.indiatimelines.com.
NASA’s Apollo astronauts established five seismic chakras, which measured thousands of chakras while operating on the Moon between 1969 and 1977, revealing seismic activity on the Moon. Various materials can change the speed of seismic waves or reflect them, allowing scientists to use these waves to learn about the internal structure of the Moon and to model their formation.
NASA is currently planning to bring astronauts back to the moon by 2024, which will lay the foundation that will ultimately enable the human discovery of Mars.
Insight’s seismometer, which Lander placed on the planet’s surface on December 19, 2018, will enable scientists to collect similar data about Mars.

Three other seismic signals came on March 14, April 10 and April 11. More sensitive details of SEIS were detected by broadband sensors, these signals were smaller and more obscure in origin than Seoul 128 events.

Regardless of this reason, Sol 128 is an exciting milestone for the signal team. “We are waiting for months like this for a sign,” said Philippe Lognonne, in the SEIS team France, Institut de Physique du Globe de Paris (IPGP).
“It is finally so exciting that Mars is still seismically active. Once we get an opportunity to analyze them, then we are hoping to share detailed results”, Mr. Lognonne said.
Most people are familiar with earthquakes on Earth, which are on the flaws caused by the speed of tectonic plates. Mars and the moon do not have tectonic plates, but they still experience earthquakes – in their cases, due to a continuous process of cooling and contraction that creates stress.
This stress grows over time unless it is strong enough to break the crust, causing an earthquake. To find these small lakes, a great achievement of engineering was needed. On Earth, high-quality seismometers are often sealed in the underground vault to separate the temperature and weather changes.
Insight’s tool has several simple insulating barriers, including a cover made by JPL, called Wind End Thermal Shield, so that it can be saved from the planet’s extreme temperature changes and high winds.
