For most people, the most shocking aspect of daily weather forecasts is that the temperature drops steadily below 130 degrees Fahrenheit and rarely exceeds 15 degrees Fahrenheit. You may also notice that there is a lot of wind – the most recent wind speed recorded is 37.8 mph. And the atmospheric pressure, generally around 700 Pascals, is considerably lower than that of the Earth, where the average atmospheric pressure at sea level is greater than 100 000 Pascals. But NASA is not so much interested in the weather, but by using these readings to get a better idea of the seismic activity on Mars.
The InSight sensor set, called the Auxiliary Payload Subsystem (APSS), is used "to detect sources of" noise "that can influence the seismometer readings of the LG. " The APSS includes a magnetometer – the first ever installed on the surface of another planet – to detect changes in the local magnetic field, but extreme temperature variations, high winds, and low air pressure can mask "marsquakes". And what NASA really wants to know is if there is seismic activity, which could tell us more about the formation of the Earth. While the agency solves this problem, she understands why not share some of the lighter data with us, Earthlings.
