Mysterious noises inside Mars, discovered by the landing of NASA | Science and technology news



NASA scientists have reported the fascinating discovery of his landing Insight on Mars – a mysterious rumble coming from the depths of the planet.

Researchers believe that seismic events may be caused by a sudden release of energy from the bowels of the planet, but the nature of this release remains unknown and mysterious.

Ironically, new noises are believed to have originated in a place on Mars called Cerberus Fossa, where two other previous events of the candidates it is believed that they arose.

Although these murmurs have sometimes been called “marshers,” the planet is not thought to have the same active tectonic system as Earth, which causes earthquakes.

Interestingly, the previous seismic events discovered by the InSight space agency are arrived on the surface of the planet in 2018, an almost complete Martian year occurred, or two Earth years ago, during Martian northern summer.

Scientists have predicted that this season will offer the probe the best opportunity to listen to earthquakes, as the winds on the planet will become calmer.

The InSight seismometer, called the Internal Structure Seismic Experiment (SEIS), is so sensitive that it must be covered by a domed shield to block it from the wind and prevent it from freezing during use.

Despite this, the wind can still cause enough vibration to mask the seismic signals it is looking for, and so the NASA team began trying to isolate the sensitive cable.

To do this, the team placed a scoop on the end of the robotic InSight lever to contaminate the soil on top of the domed shield, allowing it to drain onto the cable.

The intention is to allow the soil to approach the shield without interfering with its compaction by the ground.

Burial of the seismic rope itself is one of the goals of the next phase of the mission, which NASA recently extended for two years until December 2022.

But despite the break the wind causes in the InSight seismometer, it doesn’t do much to help the solar panels, which remain covered in dust.

Now the power ends when Mars moves away from the Sun, although the energy level is expected to increase after July, when the planet will begin to approach the Sun again.

By this time, the team is going to turn off InSight tools one by one so that it can hibernate, waking up only periodically to check on its own health, and sending messages back to Earth.

NASA said the team hopes to keep the seismometer for another month or two before it has to be turned off.
