NASA scientists have reported an exciting discovery of the Mars Insight spacecraft – a mysterious thunder from inside the planet.
Researchers believe that the sudden release of energy from inside the planet can lead to seismic events, but the nature of this release is unknown and surprising.
Interestingly, new purrs are believed to come from a site on Mars called Cerberus Phusse, where Two other programs are past candidates It is considered to be native.
Although these vibrations are sometimes referred to as “earthquakes on Mars”, the planet is not considered to have an active tectonic system similar to Earth that causes earthquakes.
Oddly enough, previous seismic events were detected by the Insight spacecraft of the Space Agency He reached the surface of the planet In 2018 – This happened during the northern summer of Mars, about a year ago on Mars, or two years ago on Earth.
Scientists predicted that this weather would provide the lander with the best chance of hearing an earthquake as the winds on the planet would cool down.
The Insight Seismometer, called the Internal Structure Seismic Experiment (SEIS), is so sensitive that it must be covered with a dome-shaped screen to keep it out of the air and to protect it from freezing when in use.
Despite this, the winds still produced enough vibrations to circumvent the seismic signals they were looking for, so the NASA team began to try to isolate the sensitive cable.
To do this, the team deployed a shovel at the end of Insight’s robotic arm to deform the ground on a dome-shaped shield, allowing it to infiltrate the cable.
The intention is to allow the ground to come as close to the shield as possible without interfering with its seal.
Burial of the seismic cord is a goal of the next phase of the mission, which NASA has recently extended for two years until December 2022.
But despite the wind blowing from the Insight’s seismometer, it does not give much hand to the landing craft’s solar panels, which are covered in dust.
Now the energy decreases as Mars moves away from the Sun, although energy levels are expected to rise after July when the planet starts approaching the Sun again.
Until then, the team will turn off the Insight devices one by one, so that they stay awake from time to time, checking their health only by periodically waking up and sending messages back to Earth.
NASA said the team was expected to run the seismometer for a month or two before closing.
