Washington DC, Apr 13: The Perseverance Rover was launched by NASA on 30th July 2020. It landed on the Jezero Crater of Mars on 18th February 2021. After landing, Perseverance started the second phase of its mission – sending back Mars’ weather report to Earth. Sensors called MEDA are being used in this mission. MEDA stands for Mars Environmental Dynamics Analyzer. These sensors can measure the temperature, wind speed and direction, atmospheric pressure, relative humidity, and dust size and shape. This was first powered (for about half an hour) on 19th February 2021. On the same day, around 8:25 Pacific Daylight Time (PST), NASA received the first data from MEDA. According to the data received, when the system just started recording, the temperature was -4 degrees Fahrenheit. Within the next 30 minutes, the temperature came down to -14 degrees Fahrenheit.
