Mars is too windy NASA has a "yurt" for the insight detector

It has been more than two months since NASA’s “Insights” detectors landed on Mars. The landing process is as smooth as everyone wants, and the location where the robot landed is ideal for placing sensitive “electronic ears”, but there are other factors at work.

In a new blog post, NASA's Jet Propulsion Laboratory revealed that the Insight Lander successfully installed a shield on top of its seismometer using its robotic arm to protect it from the common on Mars. The effects of wind and temperature changes.

The main task of Insight is to get a close look at the inner workings of Mars and to paint a clearer picture of what is happening inside Mars. Scientists want to know how similar the interior of Mars is to the Earth, and the ultra-sensitive electronic ear is the best tool for discovery.

Unfortunately, Mars is very windy and gusts can disturb the robot's readings. To mitigate the effects of the wind, a dome-shaped mask is placed on top of the sensor to protect it. The shield also has the added advantage of helping to regulate temperature and prevent the sensor from becoming too hot or too cold.

“Temperature is one of our biggest problems,” said Bruce ·, chief investigator of Insights. In a statement, Bennett said, “You can think of a shield as a cover for food on the table, it makes a seismograph. The device won't get too hot during the day and won't cool too much at night. In general, we want to keep the temperature as stable as possible. ”

According to the relevant agency, the smooth appearance of the mask helps to keep out the wind, and it is comfortably located on the surface of Mars, thanks to a “blank” made of “rugs”.

The Insight has been on Mars for a long time and the planned schedule for the mission will exceed 700 days. Of course, in the next few months, we will learn some new information about the planet, but now it is important for NASA to protect its investment from Mars.
