It's now Sol 1038 of the Mars2020 mission, and local Mars time is 21:09:42.

It's now Sol 1032 of the Mars2020 mission, and local Mars time is 01:42:31.
This is a weather report for Jezero, Mars, using data from the #MEDA instrument aboard #Perseverance.
Report Sol: 1029
Ls: 179.4°Temperature ranges in the past 6 sols:
Highs: -10.2 to -5.5°C
Lows: -74.5 to -72.2°CAtmospheric density, a parameter that influences #Ingenuity's flights, is 0.0127kg/m3, still much lower that the 0.0145kg/m3 required for normal rotor rpm.

It's now 05:22 on Sol 1020 for the #Mars2020 mission, and there has been a sign of life from #Perseverance:
A new weather report has been received after more than 10 sols, albeit it's only for Sols 1010, 1011 and 1012.
It too shows that summer is over in Jezero Crater, and maximum temperatures have started reaching below -15°C again, while pressure keeps on rising rapidly.
Note: The last image seen in #NASA's database was captured on Sol 1010.

#Ingenuity is presently experiencing some of the coldest sols since last October, with max avg abt -25°C through the week but reaching as low as -28°C max during daylight on some sols.
The animation shows a few of the last flights of the #MarsHelicopter. It's notable that all those flights occurred during max temperatures around -20°C, which might explain why #Flight51 has most probably not taken place yet. #NASA's weather feed updates lag by a few sols

The weather in Jezero, Mars, according to the MEDA instrument onboard #Perseverance.
Report Sol: 761
Temperature extremes were -79.8 and -18.6°C during the past 3 weeks. The average air pressure kept rising, while minimum air density remained above 0.015kg/m3.

The weather in Jezero, Mars, according to the MEDA instrument onboard #Perseverance.
Temperature extremes were -83.6 and -14.7°C during the past week; the average air pressure kept rising slowly, while minimum air density, important for #Ingenuity to be able to fly in low gear, remained around 0.015kg/m3.

The weather in Jezero, Mars, according to the MEDA instrument onboard #Perseverance.
Temperature extremes were -86.6 and -17.8°C during the past week; average air pressure kept rising slowly.
-
The weather in Jezero, Mars, according to the MEDA instrument onboard #Perseverance.
Temperatures averaged between -85 and -19°C during the past week; average air pressure kept rising.
Air density minimum continued rising slowly and is now above 0.015kg/m3, which allows #Ingenuity to fly in low gear.
-
The weather in Jezero, Mars, according to the MEDA instrument onboard #Perseverance.
Temperatures fluctuated between -86 and -13.4°C in the past two weeks; average air pressure kept rising.
Air density minimum is still above 0.0145kg/m3, apparently allowing #Ingenuity to continue flying in low gear.

The weather in Jezero, Mars, according to the MEDA instrument onboard #Perseverance.
The cold weather of last week has given its place to higher temperatures, although the lows are still in the mid -80s; the highs are now at the -13°C range, mostly; average air pressure kept rising.
The combination of increased temperatures and air pressure drives air density low. At a certain point (0.0145kg/m3) #Ingenuity will have to fly at higher gear.

The weather in Jezero, Mars, according to the MEDA instrument onboard #Perseverance.
As it appears, the cold temperatures observed last week may have not been due to the cold draft coming down Cannery Passage, nor the openness of the Three Forks plain. This week temperatures reached even lower (as low as -86.7°C) with highs from -25.7 to -13.4°C; air pressure rose to reach 732 Pa, a few sols ago.

The weather in Jezero, Mars, according to the MEDA instrument onboard #Perseverance.
High temperatures have returned to the -20s °C with one day dropping even below -27, and lows now reaching -84°C.
I'm guessing the change might be related to #Perseverance moving away from the protection of Cape NukShak and Whale Mountain and driving down the valley through the cold drafts of Cannery Passage and into the middle of the Three Forks plain.

The weather in Jezero, Mars, according to the MEDA instrument onboard #Perseverance.
No significant changes this past week. Both barometric pressure and temperature averages appear to have leveled out, resulting in min air density staying above 0.0145 kg/m3. This means #Ingenuity can continue flying with its rotor at lower speed (2,537 rpm).

The weather in Jezero, Mars, according to the MEDA instrument onboard #Perseverance.
Temperatures have been rising this past week, reaching as high as -16.7°C. Barometric pressure continued dropping.
Rising temperatures and dropping pressure make air thinner, which eventually will make it necessary for the #MarsHelicopter to fly with its rotor at higher speed (2700 rpm).

The weather in Jezero, Mars, according to the MEDA instrument onboard #Perseverance.
High temperatures have bounced back this week but have not exceeded -20° and lows have remained below -80°. Air density has remained around 0.0152kg/m3, which is good for #Ingenuity's rotor running at low rpm.
At higher air densities, which happen at night, MOXI oxygen production is higher. Its current record stands at 10.4 grams of oxygen per hour.

The weather in Jezero, Mars:
Another record minimum temperature, -91°C on Sol 550; max still slightly below -20°C.
