Any IT worker who has ever updated a remote system, knowing that if something goes wrong you're facing a 12 hour drive to fix it, fully understands the sheer butt clenching terror that those NASA engineers experienced for the almost full day they had to wait between deploying the update and finding out if they broke anything.
More than a full day. It would take the signal about 18.5 hrs to get to Voyager. We'd then have to wait another 18.5 hrs for the signal to get back so we could know if it worked.
Imagine driving 18 light hours. 😬 How long would that even take??
At 70 mph, that would take 172,444,276 hrs. That's about 19,635 years non-stop.
I recently watched It's Quieter in the Twilight, a fascinating documentary about the shrinking and aging team of engineers at the JPL still working on Voyager.
I messed up a server config and was terrified I had to spend an extra hour for travel. I can't imagine the pressure those NASA engineers have.
Oof yeah. When I update a Cisco firewall remotely it'll go offline for around 30 minutes to around two hours where it is completely unreachable. In the time window I'm desperately watching a continuous ping to see if it comes back up okay. If it does, I'm done. If it doesn't, it means I need to go into work and probably spend several hours on the phone trying to fix it.
Can't imagine the stress of trying to update something that is almost 20 light hours away.
