The average temperature at Jezero Crater is a chilly minus 67 degrees Fahrenheit (minus 55 degrees Celsius).
that is in contact with the planet's surface. Heat and mass in the form of dust are exchanged between the surface and the ASL, with each region affecting the other. Perseverance measured the average air temperature at Jezero to be minus 67 degrees Fahrenheit , but this can vary by as much as 90 to 110 degrees F , particularly between day and night.
Air pressure also fluctuated, both daily and more noticeably on a seasonal basis as the carbon dioxide frost at the poles sublimated in the early summer"heat," bolstering the thin atmosphere. "The pressure and temperature of Mars' atmosphere oscillate with periods of the Martian solar day … following the daily cycle of sunshine greatly influenced by the amount of dust and the presence of clouds in the atmosphere," a co-author of the report, Agustín Sánchez-Lavega of the Planetary Sciences Group at the University of the Basque Country in Spain, said in aAs the daytime sun warms the surface and lower atmosphere, pockets of air begin to rise, creating gentle turbulence that leads to some of the observed temperature fluctuations. The turbulence stops in the evening assinks down toward the horizon and solar heating drops off, allowing the air to settle, at least for a short time. Then, Perseverance often measured instability returning to the ASL at the equivalent of about 2 a.m. local time on Mars. Similar returning instability was also witnessed by NASA's, which ended its mission in December after four years on the Red Planet. MEDA has now confirmed that this is the result of the warm surface of the local terrain, enhanced by winds with gentle speeds to 6.5 to 13 feet per second driven by differences in the temperature of the surface. Speaking of the wind, MEDA measured a daily wind cycle, with strong south-easterly gusts of 82 feet per second around midday, weaker winds of 23 feet per second in the afternoon, a wind-direction reversal at night, and no winds at all between 4 a.m. and 6 a.m. local time. have shown how Perseverance has detected dust devils passing over the rover and the accompanying change in air pressure.
