We are pretty used to getting weather reports here on Earth but the Mar’s Perseverance Rover is now sending back weather reports from the Red Planet. The MEDA (Mars Environmental Dynamics Analyzer) system powered on about 30 minutes after the rover’s landing back on February 19th. Meteorological instruments have been included on previous landers and rovers including a similar system called REMS (Rover Environmental Monitoring Station) on the Curiosity rover.
More recent data from this past week has been released in preparation for the Ingenuity helicopter’s first flight in the coming few weeks. The MEDA recorded some pretty brutal weather from the surface of Mars with a high temperature of -7.6°F and a low of -117.4°F with maximum wind gusts of around 22 mph.
The MEDA instrument is also capable of recording many meteorological readings including relative humidity, pressure, ground temperature, and temperatures as much as 100 meters up. This instrument is expected to help improve the understanding of Martian weather and climate including heat fluxes and dust patterns.
