To the average person, probably the most shocking aspect of the daily weather report is that the temperature regularly drops below 130 degrees Fahrenheit and rarely goes above 15 degrees Fahrenheit. You may also notice that it's rather windy – the most recent wind speed recorded at 37.8 mph. And the atmospheric pressure, usually somewhere around 700 Pascals, is considerably lower than Earth's, where the average sea-level atmospheric pressure is more than 1
InSight's package of sensors, called Auxiliary Payload Subsystem (APSS), is being used to detect sources of 'noise' that could influence readings from the lander's seismometer. " APSS includes a magnetometer – the first ever placed on the surface of another planet – to pick up changes in the local magnetic field, but the planet's extreme temperature swings, high winds and low atmospheric pressure can all mask "marsquakes." And what NASA really wants to know is if there's seismic activity, which could tell us more about how Earth formed. While the agency sorts that out, it figures out why not share some of the lighter data with us Earthlings.
