[ NASA receives first weather reports from Perseverance rover on Mars at Jezero Crater ]

Many things are taking place:

NASA Perseverance rover’s first Mars weather report will make you shiver

MEDA took its first readings on Feb. 19, not long after the rover’s landing on Mars. That first weather report showed it was about minus 4 degrees Fahrenheit (minus 20 degrees Celsius) at the surface. The temperature dropped over the next 30 minutes to minus 14 degrees Fahrenheit (minus 25.6 degrees Celsius).

The system has been collecting data since its first weather report and has logged temperatures as low as minus 117.4 degrees Fahrenheit (minus 83 degrees Celsius) with wind gusts of up to 22 mph (10 meters per second).

NASA’s first weather report from Jezero Crater on Mars

The weather often plays a role in our daily plans. You might put on a light jacket when the forecast calls for a cool breeze or delay your travel plans because of an impending storm. NASA engineers use weather data to inform their plans, too, which is why they’re analyzing the conditions millions of miles away on Mars. The Mars Environmental Dynamics Analyzer (MEDA) system aboard NASA’s Perseverance rover first powered on for 30 minutes Feb. 19, approximately one day after the rover touched down on the Red Planet. Around 8:25 p.m. PST that same day, engineers received initial data from MEDA.

NASA gets first weather report from the Jerezo Crater Mars

NASA has shared the first weather report from Jezero Crater on Mars ‘ and the once ancient lake appears to experience frigid temperatures.

The data shows that it was just below -4F on the surface when MEDA turned on, but dropped to -14F 30 minutes later.

MEDA is designed with a suite of environmental sensors to record dust levels and six atmospheric conditions, along with the ability to measure radiation budge near the surface that will help prepare the first humans to explore Mars.

Jose Antonio Rodriguez Manfredi, MEDA principal investigator with the Centro de Astrobiolog’a (CAB) at the Instituto Nacional de Tecnica Aeroespacial in Madrid, said: ‘After a nail-biting entry descent and landing phase, our MEDA team anxiously awaited the first data that would confirm our instrument landed safely.

NASA gets first weather report from Mars rover landing site

In addition, the MEDA radiation and dust sensor showed that the crater was experiencing a clearer atmosphere than the Martian Gale Crater around 2,300 miles away.

The MEDA pressure sensors also noted that the pressure on Mar was within a predictable range of 718 Pascals.

Over the course of the next year, MEDA will provide NASA will readings of solar radiation intensity, cloud formations and winds, dust cycles, and heat fluxes and temperature cycles.

It is able to record the temperature at three atmospheric heights and also records the radiation budget near the surface.

The Perseverance rover is sending weather reports back from Mars

And now for the weather ‘from Mars. NASA scientists have analysed the first meteorological reports recorded by its Perseverance rover on the Red Planet. The short version: if you’re planning to spend some time at the Jezero Crater, you’ll need a coat (yes, and a spacesuit) because it’s -20’C on a warm day.

The rover, which landed in February, is equipped with a planet-hopping weather station called the’Mars Environmental Dynamics Analyzer (MEDA). Its sensors record wind speed and direction, air and ground temperature, as well as pressure, humidity and radiation. Its first measurements were taken the day after it landed and MEDA wakes itself up every hour to take fresh readings.
