I know its memes, but the astronaut tim peake discussed the space suits on No Such Thing As A Fish where he said that the whole get-up is like 16+ layers thick, and the only heating inside is for your fingertips, so you dont lose fine motor function. He said you can be sitting working on a panel outside the station, with one hand facing the sun and one hand facing the shade, and the delta-T of your two hands could be something like 500°C.
Maaaaadness! (It's been a while since I listened to this episode, my memory of numbers could be skewed.)
What is a "delta-T?"
Yeah, sorry. Its difference in temperature. I got delta-T in my head and blinkered in on either making a 'triangle' to denote delta or just write it out, instead of just saying temperature difference.
Apologies.
Difference in temperature.
