Comment on India fails to re-establish communication with its Moon probe
PetDinosaurs@lemmy.world 1 year agoThe Mars has an atmosphere and a more typical day length. It doesn’t get that cold there.
The length of a day on the moon is 29.5 days, and there’s not atmosphere.
The rover spend 14 days at a few degrees above absolute zero.
Electronics don’t survive that. Weird shit happens when it gets that cold.

Er, no. Absolute zero is -273.15°C (-459.67°F) while the moon at its coldest is about -173.15°C (-297.67°F) so you’re about 100°C off.

Whoops. You’re right…F and C confusion.

Ha, I do it all the time as a Canadian living in the States.

Yeah. I’m used to all the scientific stuff being metric, and only conventional for stuff that doesn’t matter. I saw -270 when I looked it up and thought “that’s about 3 K, I guess that’s feasible”.
I do think unit fights are stupid, though. Units are about communicating and understanding.
I learned that DC fast chargers are around 250 kW. I can tell you how fast that could boil a cubic meter of water or all kinds of science things, but that’s not meaningful to me.
I can then tell you that that’s enough to trip the big breaker on five houses. That’s a bit more meaningful to me, but how much is a house.
Now, how many ovens set to max is that? I know how hot an oven is. It’s more than 80 ovens. That’s a much better unit, but I still can’t really understand 80 ovens.

As someone who grew up in Canada during the transition to metric, I think I might go into an infinite loop if I moved to the US. Ok the temp is 72 f which is 22 C which is 72 f which is…
