Re: time
I had not given thought to how computing was handled at the ISS. It does make lots of sense though that a long term Mars mission will be much more efficient if there's an onboard computing system. I would have thought though that someone must have thought about testing super computing on space craft before now. Would this be the first test ever?

Re: time
@Scott true, especially when critical life support systems are in danger.

Re: time
@Ariella: I also think of it as a safety issues. If there was a mission to Mars, would you want to wait 40 minutes for critical information to go back and forth across space? I think you'd want as littel lag time as possible.

From Earth to Mars
Ariella — Two decades ago the ISS didn’t exist. I don’t think a 40-minute delay in data transmission is too much for a 34 million miles data travel to or from Mars. At least for now, you can’t have instant computing in such distance, not even with a supercomputer. The next generation of exascale supercomputers may solve the problem, though. You just have to wait three more years —perhaps a little less— for the first exascale supercomputer to be launched to the ISS and Mars.

time
MRight now, most computing is done on Earth and transmitted either to a space shuttle or the ISS. That works well in low-orbit situation, but Mars is nearly 34 million miles from Earth, which means sending and receive information from standard computer systems could take up to 40 minutes, according to HPE.> You know, a decade or two back a 40 minute delay wouldn't have sounded unreasonable. But today we've gotten accustomed to instant computing.
