NASA gets first weather report from the Jerezo Crater Mars using a system strapped to Perseverance
NASA has shared the first weather report from Jezero Crater on Mars – and the as soon as historic lake seems to expertise frigid temperatures.
The Mars Environmental Dynamics Analyzer (MEDA) system aboard the Perseverance rover captured the surrounded temperatures for half-hour February 19 at round 10:25pm ET.
The information reveals that it was just under -4F on the floor when MEDA turned on, however dropped to -14F half-hour later.
MEDA is designed with a suite of environmental sensors to document mud ranges and 6 atmospheric situations, together with the potential to measure radiation budge close to the floor that may assist put together the first people to discover Mars.

Jose Antonio Rodriguez Manfredi, MEDA principal investigator with the Centro de Astrobiología (CAB) at the Instituto Nacional de Tecnica Aeroespacial in Madrid, stated: ‘After a nail-biting entry descent and touchdown section, our MEDA crew anxiously awaited the first information that may affirm our instrument landed safely.
‘Those had been moments of nice depth and pleasure. Finally, after years of labor and planning, we obtained the first information report from MEDA.
‘Our system was alive and sending its first meteorological information and pictures from the SkyCam.’
MEDA is strapped to Perseverance’s mast by an extendable arm that’s launched periodically to test the weather.

It weighs about 12 kilos and is ready to seize wind (each pace and course), stress, relative humidity, air temperature, floor temperature and radiation (from each the Sun and house).
The system wakes itself up each hour, and after recording and storing information, it goes to sleep independently of rover operations.
And MEDA can function even when Perseverance is asleep.
When NASA obtained the first weather report, they shortly went to work to piece it collectively.

MEDA’s radiation and mud sensor confirmed Jezero was experiencing a cleaner environment than Gale Crater round the identical time, roughly 2,300 miles away, in accordance to reviews from the Rover Environmental Monitoring Station (REMS) aboard the Curiosity rover stationed inside Gale.
And MEDA’s stress sensors instructed engineers the stress on Mars was 718 Pascals, effectively inside the 705-735 Pascal vary predicted by their fashions for that point on Mars.
The system will acquire, retailer and transmit particles work together with gentle, in the end affecting each the temperature and weather.
Although these information factors assist NASA higher put together Perseverance, the measurements are additionally very important for future house faring heroes and hobbits that may in the future journey to Mars.
Manuel de la Torre Juárez, deputy principal investigator for MEDA at NASA’s Jet Propulsion Laboratory in Southern California, stated: ‘We’re very excited to see MEDA working effectively.

As Ingenuity achieved pre-flight milestones, a MEDA report from the forty third and forty fourth Martian days, or sols, of the mission (April 3 to 4 on Earth) confirmed a temperature excessive of -7.6F and low of -117.4 F in Jezero Crater. MEDA additionally measured wind gusts at round 22 mph
‘MEDA’s reviews will present a higher image of the surroundings close to the floor. Data from MEDA and different instrument experiments will reveal extra items of the puzzles on Mars and assist put together for human exploration. We hope that its information will assist make our designs stronger and our missions safer.’
MEDA can document the temperature at three atmospheric heights: 2.76 ft, 4.76 ft , and 98.43 ft, as well as to the floor temperature.
The system makes use of sensors on the rover’s physique and mast and an infrared sensor able to measuring temperature almost 100 ft above the rover, which is essential for when the Ingenuity helicopter takes flight.

Perseverance, together with its journey companion Ingenuity, touched down on Mars February 18 with the mission of seek for indicators of historic life in the Jezero Crater in a bid to assist scientists higher perceive how life developed on Earth.
