India fails to re-establish communication with its Moon probe::undefined
You must log in or register to comment.
The Vikram lander and rover weren’t designed to survive the lunar night so this was expected, but a loss nonetheless.
Right? It was planned.
14 days in really cold and dark is really harsh for any electronics. Unless it had a radio isotopes generator, I can’t imagine much of anything electronics surviving.
Im only half joking here but I bet the problem is because the probe is trying to send a signal to India, but modi already had them change everything to say Bharat so now the probe can’t communicate with an unknown server or something
This has to be the most brain dead argument lmao.

Half joke.
How did NASA handle the comms with Curiosity? Maan you’ve got to appreciate NASAs engineuity
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 earth days, and there’s no atmosphere.
The rover spent 14 days *in total darkness and cold
Electronics don’t survive that. Weird shit happens when it gets that cold. Not to mention something simple like thermal expansion breaking a trace.
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.
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…
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.
