NASA shared the first weather report of the Jezero crater on Mars – and it seems that the once old one is experiencing colder temperatures.
The Mars Environmental Dynamics Analyzer (MEDA) system aboard the Perseverance Rover captured ambient temperatures for 19 minutes on February 19 at about 10:25 p.m. ET.
The data show that it was just below -4F on the surface when MEDA switched on, but dropped to -14F 30 minutes later.
MEDA is designed with a series of environmental sensors to record dust levels and six atmospheric conditions, along with the ability to measure radiation levels near the surface, which will help prepare the first humans to explore Mars.

Jose Antonio Rodriguez Manfredi, MEDA Principal Investigator at the Centro de Astrobiología (CAB) at the Instituto Nacional de Tecnica Aeroespacial in Madrid, said: ‘After a nail-biting descent and landing phase, our MEDA team was anxiously awaiting the first data that would confirm that our instrument has landed safely.
“It was moments of great intensity and excitement. Finally, after years of work and planning, we received the first data report from MEDA.
“Our system lived and sent its first meteorological data and images from the SkyCam.”
MEDA is fastened to Perseverance’s mast by a durable arm that is regularly released to examine the weather.

MEDA is fastened to Perseverance’s mast by a durable arm that is regularly released to examine the weather. It weighs about 12 kilograms and is capable of capturing wind (both speed and direction), pressure, relative humidity, air temperature, ground temperature and radiation (from both the sun and space).

The system wakes itself up every hour, and after being recorded and stored, it goes to sleep independently of the rover operations.
And MEDA can function, even if perseverance is dormant.
When NASA received the first weather report, they quickly went to work compiling it.

According to reports from MEDA’s radiation and dust sensor, Jezero experienced a cleaner atmosphere at the same time as the Gale crater, about 2,300 kilometers away, according to reports from the Rover Environmental Monitoring Station (REMS) aboard the Curiosity rover in Gale is stationed.
And MEDA’s pressure sensors told engineers that the pressure on Mars was 718 Pascal, which was predicted within the 705-735 Pascal range by their models for that time on Mars.
The system will collect, store and transfer particles, which interact with light, which ultimately affects the temperature and weather.
Although these data points help NASA better prepare for perseverance, the measurements are also essential for future space heroes and hobbits who will one day travel to Mars.
Manuel de la Torre Juárez, deputy chief investigator for MEDA at NASA’s Jet Propulsion Laboratory in Southern California, said: ‘We are very excited to see that MEDA is working well.
Since Ingenuity reached milestones before the flight, a MEDA report of the 43rd and 44th Mars Days, or sols, of the mission (April 3 to 4 on Earth) has a temperature of -7.6F and a minimum of – 117.4 F shown in Jezero crater. . MEDA also measured gusts of approximately 22 km / h
‘MEDA’s reports will give a better picture of the environment near the surface. Data from MEDA and other instrument experiments will reveal more pieces of the puzzles on Mars and help prepare for human exploration. We hope its data will help make our design stronger and our missions safer. ‘
MEDA can record the temperature at three atmospheric heights: 2.76 feet, 4.76 feet and 98.43 feet, in addition to the surface temperature.
The system uses sensors on the body and the machine and an infrared sensor that can measure the temperature of about 100 feet above the car, which is crucial when flying the Ingenuity helicopter.

Perseverance, along with his travel companion Ingenuity, struck on February 18 with the mission to search for signs of ancient life in the Jezero crater, to help scientists better understand how life on earth evolved.
NASA MARCH 2020: THE MISSION WILL SEEK THE PERSEVERANCE ROVER AND INGENUITY HELICOPTER
NASA’s Mars 2020 mission will search for signs of ancient life on the Red Planet in an effort to help scientists better understand how life on Earth evolved.
Named Perseverance, the main car size will explore an ancient river delta in the Jezero crater, which was once filled with a 1600 meter deep lake.
It is believed that the region offered microbial life about 3.5 to 3.9 billion years ago, and the rover will examine soil samples to look for evidence of life.
Nasa’s Mars 2020 rover (artist’s impression) will look for signs of ancient life on Mars to help scientists better understand how life evolved on our own planet.
The $ 2.5 billion Mars 2020 spaceship (£ 1.95 billion) was launched on July 30 with the rover and helicopter inside – and successfully landed on February 18, 2021.
Perseverance has landed in the crater and will collect samples that will eventually be returned to Earth for further analysis.
A second mission will fly to the planet and return the monsters, perhaps by the later 2020s in partnership with the European Space Agency.
