Hi, Yesterday it was quite a bit warmer on Mars than in most of Canada, and some of the northern States.

http://www.cbc.ca/m/touch/technology/story/1.2895092

It must be Summer there... apparently it gets up as high as +20C (68F) on Mars. Unfortunately the lows around -150C (-238F) are uninhabitable.

Around here (Northern BC, Canada) it often gets to -40C (also -40F), and nothing works well. Plastic items often shatter, tires get flat spots on the bottom. I can't imagine how they make Mars Rovers and stuff like that, that actually work at -150C. They must use totally metals, and talc as a lubricant.

Engine oil and grease are ineffective below -35C (-30F). I often wondered how they lubricate things in space.

Bye for now,

Troy

I once worked for an outfit that designed/built hardware for launch into deep space. We lubricated flight mechanisms with a synthetic products called Tribolube and Alisyn. http://tribolube.net/tribolube-aerospace.php

These products lubricate reliably in hard vacuum and in temps from -160 - 600 degF. But the stuff is also CRAZY expensive!
 
Might be summer there, but if it is, it's also winter somewhere else on Mars, just like it is on Earth. I think that "news story" cherry-picked it's martian temperature.
 
Tell your wife I look a bit like ZZ top, without all that thar rock star money, lol
