The weather plays a major role in our daily routine. You can wear a light jacket when the forecast calls for cool air or delays your travel plans due to an impending storm. NASA engineers use weather data to report their plans, which is why they are exploring conditions millions of miles away on Mars.
The Mars Eco Dynamics Analyzer (MEDA) system on NASA’s diligent rover first runs for 30 minutes on February. February 19, almost a day after the rover touched down on the Red Planet. At 8:25 pm on the same day BST, the engineers received the initial data from Meda.
“After the nail biting entry descent and landing phase, our meta team was eagerly awaiting the first data to confirm that our instrument landed safely,” said Jose Antonio-Rhoda, Meta’s Chief Investigator with Centro de Astrobiology (CAP) at the Institute. National de Technica Aerospace in Madrid. “Those were moments of great intensity and excitement. Finally, after many years of work and planning, we received the first data report from Meta. Our system was alive and sending its first weather data and images from Skycom.”
The Meta weighs about 12 pounds (5.5 kilograms) and has a set of environmental sensors to record dust levels and rivers Atmospheric conditions(Wind (both direction and direction), pressure, humidity, Air temperature, Ground temperature and radiation (from both the sun and space). The system wakes itself up every hour, and after recording and storing data, the rover sleeps independently from operations. The computer records whether the rover is awake or not, both day and night.
As engineers received the first data points of the meta on Earth, the team put together its first meteorological report from Mars’ Xero gorge.
Data showed that when the computer started recording it was below minus 4 degrees Fahrenheit (minus 20 degrees Celsius), and that temperature dropped to minus 14 degrees Fahrenheit (minus 25.6 degrees Celsius) within 30 minutes.
According to the Rover Environmental Observatory (REMS) on the Curiosity rover, which was parked inside the creek, the mezzanine’s radiation and dust sensor showed that Jessero was enjoying a cleaner environment than the gale abyss, which is about 2,300 miles (3,700 km) away at the same time. MEDA’s pressure sensors told engineers that the pressure on Mars was 718 pascals, within the range of 705-735 pascals predicted by their models on Mars at the time.
Controlling Atmospheric Space
Thanks to telescopes on Earth and spacecraft orbiting Mars, scientists have a better understanding of the Red Planet’s climate and have some insight into the magnitude of dust storms throughout a Mars year (two Earth years). However, forecasting dust and traffic or how small storms will form larger around the entire planet could be useful for future scientific and research work.
Over the next year, the meta will provide valuable information on temperature cycles, heat fluxes, dust cycles and how dust particles interact with light, which will eventually affect both temperature and weather. Meta’s readings on solar radiation intensity, cloud patterns, and local winds may indicate the design of the planned Mars model return mission. In addition, these measurements will help engineers better understand how to prepare humans and habitats to cope with the conditions on Mars.
REMS at Curiosity Rover currently offers similar daily weather and atmospheric data. Meda, formed through an international collaboration, develops REMS’s autonomous weather station system and has undergone some improvements. This system was provided by Spain and developed by CAB with the contribution of the Finnish Meteorological Agency. The U.S. contributions were funded by the Game Transformation Development Program within NASA’s Directorate of Space Technology Mission.
Boasting higher overall life and additional temperature measurements, the meta temperature can be recorded at three atmospheric altitudes: 2.76 feet (0.84 m), 4.76 feet (1.45 m), and 98.43 feet (30 m), in addition to the surface temperature. The system uses the rover’s body and mast sensors, as well as an infrared sensor that can measure 100 feet above the rover. It also records the radiation budget near the meta surface, which is ready for future human exploration missions to Mars.
With Meta’s weather reports, engineers now have atmospheric data from three different locations on the Red Planet – diligence, curiosity and NASA’s Insight Lander, which provides temperature and wind sensors for the Insight (Twins). The trio will help you gain a deeper understanding of Mars’ weather patterns, events and atmospheric turbulence, which could affect plans for future missions. In the near future, Meda’s data will help determine the best atmospheric conditions for intelligent helicopter flights.
A meta report from the 43rd and 44th Tuesdays, or April 3-4 on Earth, that the temperature reached minus 7.6 degrees Fahrenheit (minus 22 degrees Celsius) and the lower Xero abyss minus 117.4 degrees Fahrenheit (minus 83 degrees Fahrenheit) ). MEDA measures gases of air at 22 miles (10 meters per second).
“We are very pleased to see that Meta is performing better,” said Manuel de la Torre Jures, Meta’s Deputy Chief Analyst at NASA’s Jet Propulsion Laboratory in Southern California. “MEDA’s reports provide a better picture of the environment near the surface. Data from the MEDA and other instrument tests reveal many parts of the mysteries on Mars and are ready for human exploration. We hope that its data will help us to strongly change our designs. Our missions are safe.”
