Home / Science / Scientists are waiting for a "Marsquake" to reveal what is hidden beneath the surface of Mars

Scientists hope that an imminent voyage to Mars will show what is below the surface of the Red Planet.

But they will not degrade to the core, but plan to wait for an asteroid shatters the surface of Mars and causes an earthquake ̵

1; or more precisely, a Martian earthquake.

The InSight spacecraft (interior exploration with seismic surveys, geodesy, and heat transport) will be a stationary landing mission that measures seismic activity.

The goal is to understand the formation and evolution of Mars.

Curtin University researcher Katarina Miljkovic works with NASA to analyze the returned data and explain that not everything burns out due to Mar's thinner atmosphere

"So, when we look at the earth, We often see fireballs or shooting stars in the atmosphere, and these are space rocks that burn in the atmosphere, "she said.

"The atmosphere on Mars The sphere is much thinner, and when these meteorites cross the atmosphere on Mars, they do not necessarily burn in the Martian atmosphere.

" We would expect to see a star, but also one Impact on the ground. "

It is these ground effects that Ms. Miljkovic will use to read what's below the surface

"They cause seismic tremors and they cause a kind of quake," she said. [19659005] "It's similar to earthquakes, although we mostly get tectonic earthquakes on Earth, but on Mars we expect more quakes as a result of collisions."

Ms. Miljkovic said every seismic wave was different than different materials (19659005) "That can tell us how thick the crust was, what physical properties the crust had, whether we had reached the mantle and what properties it has" she said] "So basically it gives us direct information about the structure of the interior."

Despite the interest in Mars as the future home of humanity, little is known about the composition of the planet.

Ms. Miljkovic said the InSight lander should be deep in what dive the planet consists of.

"We know a bit about the crust, but we do not know much about the deep inside," she said.

"We do not know details about the crust and there is a lot of uncertainty associated with the knowledge we know so far.

" So we're really trying to gain new depths of knowledge through InSight because that's the first time we do that. "[19659026] A Story of Failures

The mission begins next month, and NASA hopes to land the spacecraft on Mars by November.

Professor Jonti Horner said "The story of the missions on Mars is well filled with failure." [19659005] "It's remarkable how difficult it was in history to ever come to Mars," he said.

"I think for all missions on Mars we speak With a success rate of 50 percent many missions went wrong.

"We are better at it, but we should always keep in mind that space flight is not safe, it is still a challenge."

Nevertheless, Professor Horner hopes the mission will be able to reveal how Mars was created.

"What we do as astronomers is sitting on the scene of a four and a half year, millions of years after it happened," he said.

"The planet has formed and we are now picking up the pieces and looking at the clues trying to put this process together."
