NASA scientists have made an amazing discovery on Mars with their Insight lander – a mysterious roaring noise from inside the planet.
Researchers believe that the sudden release of energy from the planet may have caused seismic events, but the nature of that release is unknown and confusing.
Oddly enough, the new commotion is believed to have come from a place on Mars called Cerberus fossa, where The previous two candidate events Their origin is believed to be.
Although these disturbances are sometimes referred to as “earthquakes”, the planet does not have an active tectonic system similar to Earth’s, which is believed to cause earthquakes.
Strangely, previous seismic events were detected by the space agency’s Insight lander Came to the surface of the planet In 2018 – North Mars summer occurred with almost a full Mars year or two Earth years.
Scientists had predicted that this time of year would be the best chance to hear earthquakes as the planet’s air is calm.
Insight’s seismic measurement, also known as seismic testing for the interior structure (SEIS), should be covered with a dome shield to protect it from the wind and prevent it from freezing during use.
Even so, the wind will still cause enough vibrations to mask the attempted seismic signals. So the NASA team began to isolate the delicate cable.
To do this, the team placed the end of the Insight robot arm on a swinging floor above the dome-shaped shield and lowered it into the cable.
The purpose is to bring the floor as close to the shield as possible without compromising on the ground waterproofing.
Researchers are learning to differentiate between seismic signals
One of the objectives of the next phase of this project, which NASA recently extended to two years until December 2022, is to bury seismic bonding.
But despite the confusion that wind causes insight seismic measurement, it does not help much to lander the solar panels, which are covered in dust.
Energy is now low as Mars moves away from the Sun, although energy levels are expected to increase as the planet approaches the Sun again after July.
Until then, the panel will turn off the Insight tools one by one so it can go to sleep. It would inevitably wake up to check its own health and send a message to Earth.
NASA says the team hopes to be out for a month or two before the quake’s magnitude goes off.
