I do not need a weatherman to know how the wind blows on Mars



NASA's newest Mars lander has a very accurate weather package, and you can check the daily conditions on Elysium Planitia online. However, the data seems to have led to a riddle. According to Ars Technica, there is an inexplicable peak in air pressure every day at 7:00 am and at 7:00 pm local time.

The TWINS package of the Spanish Centro de Astrobiología shows the small peaks regularly since the lander encountered him ground in November. They seem to correspond to the local sunrise and sunset. Remember that the pressure on Mars is very low (about 1% of the earth's atmosphere), and scientists have already ruled out equipment problems.

The technical side of TWINS includes thermometers and an anemometer for measuring wind speed and direction twice per second. Additional sensors include the InSight FluxGate (IFG) magnetometer provided by UCLA to measure the direction and magnitude of magnetic fields. and a highly sensitive barometer from JPL. The sensors have picked up a few puzzles, including an unexplained "infrasound". Further information about the weather station can be found on the NASA website.

As proof that social media is everywhere, the lander has its own Twitter account . and post small selfies and tidbits about his day. If you want to hear what Lander hears you can enjoy the NASA phone system recorded in the following video.

We looked at InSight extensively last year. Before you begin planning your next Elysium Planitia holiday, read the following. [1
