After all the probes let's talk about what we have learned.
Mars rotates every 24 hours or so like Earth, but it rotates at half the speed as Dana observed.
This allows for ground temperatures to reach above freezing into the Arctic boundaries.
The atmosphere maintains a pressure of 6.5 millabars. This is above the triple point of water.
Water snow falls above 50 degrees latitude at night, when conditions allow.
Seasonal methane plumes suggest micro biology or geologic activity. It must be argued that geology is not seasonal.
