The Lake Crater average temperature is -55° Celsius
NASA and American Aeronautics shared information about the successes of the Perseverance Rover on the Red Planet.
Many weather sensors are scattered around the rover. Collectively, they are called MEDA (Mars Environmental Dynamics Analyzer). Scientists published a MEDA report that shows the weather conditions for the first 250 sols (Martian days) of the project. Each sol is approximately 40 minutes longer than Earth. The results reveal a remarkablely dynamic atmosphere close to the Red Planet’s surface.
Created by Spanish scientists led by José Antonio Rodríguez-Manfredi of the Center for Astrobiology in Madrid, MEDA includes five button-sized sensors that routinely measure Martian air temperatures at four different altitudes to create a vertical temperature profile; two wind speed sensors; and additional sensors to measure radiation, dust, humidity and atmospheric pressure.
Perseverance has determined that the average air temperature in the Lake Crater is -55°C, but it can vary from -50°C to -60°C. There are also fluctuations in atmospheric pressure daily as well as more seasonally.
The wind is generally calm from noon to 3 p.m. There are strong southeasterly winds at 25 m/s and weak winds at 7 m/s in the afternoon. At night, the wind direction changes and there is no wind between 4 and 6 a.m. local time.
