The Perseverance rover has transmitted weather data from the Jezero Crater on the Red Planet. The rover records weather conditions using a special monitoring system (MEDA).

The monitoring system has a set of sensors that record the level of dust, wind speed and direction, pressure, relative humidity, air temperature, soil temperature, and radiation. MEDA captures data every hour, day and night. After recording the information, the system goes into sleep mode, regardless of what the rover is doing.

NASA Shared a Sound From Perseverance Rover as It Travels Through Space
DPA Microphones of Alleroed, Denmark, processed the sound file. That same company manufactured the rover’s microphone.

The system first turned on for half an hour on February 19, about a day after Perseverance landed on Mars. The air temperature was minus 20°C, but after half an hour, it dropped to minus 25.6°C.

A dust sensor showed that Jezero Crater has a cleaner atmosphere than Gale Crater, which is 3,700 km away. The dust level in Gale's crater was reported by another rover, Curiosity.

The pressure on the planet was 718 Pascals, the normal atmospheric pressure for Earth is 101,325 Pascals.

On April 3 and 4, the monitoring system recorded the highest temperature below zero – minus 22°C and the lowest – minus 83°C. Wind gusts reached 10 m/s.

The Perseverance Rover Runs on the Same Processor as the 1998 iMac
The iMac G3 used the PowerPC 750, which at one time was way ahead of its competitors in performance. It had a single core clocked at 233 MHz with 6 million transistors and was based on a 32-bit architecture.

NASA's Perseverance Mars rover successfully landed on the planet's surface on February 18. This is already the fifth successfully launched US rover. It will continue the geological exploration of its predecessors.
