NASA’s first Perseverance rover Mars weather report will give you chills.

I love to imagine the Perseverance Mars rover as a weather reporter standing in front of a green screen with the Jezero Crater’s map view telling us all about the fresh, chilly air that swept across Mars in the day. that We will pay according to NASA’s statement Tuesday giving the rover the first weather report from the Red Planet.

Perseverance is equipped with the Mars Environmental Dynamics Analyzer (MEDA) system that collects data on air and ground temperature, relative humidity, radiation, pressure and wind speed and direction.

The first reading of the MEDA was read on Feb. 19, shortly after the probe landed on Mars. The first weather report showed a temperature of about minus 4 degrees Fahrenheit (minus 20 degrees Celsius) at the water surface, the temperature dropped over the next 30 minutes to minus 14 degrees Fahrenheit (minus 25.6 degrees Celsius).

The system has collected data since the first weather report and recorded temperatures as low as 117.4 degrees Fahrenheit (minus 83 degrees Celsius) with gusts of up to 22 miles per hour (10 meters per second).

Climate will be of great importance in the experiment. Intelligent helicopter The first test flight is approaching. Rotorcraft must Keep warm throughout the cold Mars night. And the wind is a potential danger when it rises into the air.

“Over the next year, MEDA will provide valuable data on temperature cycles, heat fluxes, dust cycles and how dust particles interact with light, ultimately affecting both temperature and weather,” NASA said. Scientists plan future missions for both machines and humans.

Mars fans can compare the weather in Jezero Crater with other spots on the red planet. The Curiosity rover delivers weather from Gale Crater, and InSight lander checks the Elysium Planitia (although Lander’s report is currently in busy).

They all agree, though: Mars is cold.
