Man, it's as nearly perfect as it can be outside-
Cobalt blue sky and a light breeze, 78 degrees with low humidity.
I weeded what the deer have left of my garden, then started tinkering with the old pickup I just bought. (More on that later.)
This weather makes you want to stay out of doors!
When the weather is NOT like today I think about how work gets done. I'm always surprised when I go to visit Big Bubba in Phoenix to see work crews out in temperatures of 110 degrees, but then think, "If they didn't work in these temperatures, no work would ever get done!"
The other night we were watching another episode of "Ice Road Truckers"... they're operating on the "Dalton Highway" in Alaska on this segment. They showed how they prepare trucks to operate in temperatures of -40 degrees and less.
We don't like working in temperature extremes. Our machines don't much like it either. I've done no research on the reasons why, so maybe one of you can educate me, but it seems the reason why is we are limited to using resources formed in our environment, particularly our fuels, lubricants, and cooling fluids. Through our use of chemistry we have learned to operate in more extreme temperatures, both hot and cold. I think we've extended our abilities further into the cold extremes than the hot... witness the two rovers we landed on Mars. Both survive and operate in extreme cold conditions.
Neither we, nor our machines do real well in extended temperatures above 100 degrees Fahrenheit, and almost nothing works for long above a temp. of 130 or so.
Considering these limitations, how will we ever get up close and personal with the extremes we'll encounter on Mercury, or the toxic environment of Venus? Will we continue to make small technological steps until we can build machines that will work there? Or will we have a "Eureka" moment when someone thinks outside the box and solves the problem with a brilliant idea?
I'm sure it'll be a little of both.
And that journey itself will be fun to watch.
