Mars Environmental Dynamics Analyzer

[2][3] Specifically, the information obtained will help address future human exploration objectives, as dust sizes and shapes, daily weather report and information on the radiation and wind patterns on Mars, that are critical for proper design of in situ resource utilization systems.

[2][3] MEDA is a follow-on project from REMS, of the Curiosity rover mission.

On April 8, 2021, NASA reported the first MEDA weather report on Mars: for April 3–4, 2021, the high was "minus-7.6 degrees, and a low of minus-117.4 degrees ... [winds] gusting to ... 22 mph".

[3][8] MEDA is a suite of environmental sensors designed to record dust optical properties and six atmospheric parameters: wind speed/direction, pressure, relative humidity, air temperature, ground temperature, and radiation (UV, visible, and IR ranges of the spectrum).
