Within a year: First astronaut travelling to GEO, to physically reset a satellite with a broken ssh config.
- GlenTheMachine 8y agoAn astronaut at GEO would exceed their lifetime radiation exposure limit in less than an hour (in a spacesuit). The reset is gonna be robotic.

- w1nt3rmu4e 8y agoThat's interesting. Do you have source(s) for that? I'm not a 'the Moon landings were faked' person, but how does this reconcile with manned Moon missions? [Edit] So I don't have to add another comment: My first thought was, 'oh shit, how long before someone hacks one of these and repurposes it?'
- okl 8y agoHere is a NASA booklet on the topic of radiation and manned spaceflight: https://www.nasa.gov/pdf/284273main_Radiation_HS_Mod1.pdf https://www.nasa.gov/pdf/284273main_Radiation_HS_Mod1.pdf

Apparently, the Apollo astronauts had a 43% mortality rate from cardiovascular disease, which the research quoted in this article attributes to radiation.
- JorgeGT 8y agoHere's a NASA technical note specifically about Apollo mission radiation, in Table 1 you can find the radiation measured for each mission. Then again, no major solar flares happened during the missions. In table 2, the rules that were prepared on how to react to these events can be found: https://www.hq.nasa.gov/alsj/tnD7080RadProtect.pdf https://www.hq.nasa.gov/alsj/tnD7080RadProtect.pdf
- GlenTheMachine 8y agoThe Apollo astronauts a) were inside a spaceship, not performing an EVA; and b) passed through the Van Allen belts pretty quickly; and c) the Apollo trajectory was actually optimized to expose astronauts to the least amount of radiation possible. This is a pretty good discussion: https://www.popsci.com/blog-network/vintage-space/apollo-rocketed-through-van-allen-belts#page-3 https://www.popsci.com/blog-network/vintage-space/apollo-roc... Unfortunately the references I have for the “one hour” claim (which, to be fair, has a lot of uncertainty associated with it - it depends on the current space weather, where you are wrt your spacecraft, the engineering of your space suit, etc.) are all behind paywalls. Here’s one, if you can get it: https://link.springer.com/chapter/10.1007%2F978-1-4613-1567-4_6 https://link.springer.com/chapter/10.1007%2F978-1-4613-1567-...
- quickthrower2 8y agoCheaper to send a replacement satelite perhaps?
- 0db532a0 8y agoWhat is GEO? X earth orbit? I imagine outside of the magnetosphere given that you mention radiation?
- GlenTheMachine 8y agoGeosynchronous orbit. It's an orbit, 22,500 miles high above the equator. It has an orbital period of 24 hours so spacecraft there appear to be in a fixed point of the sky. It falls in the outer part of the Van Allen belts, coincidentally, so radiation there is much worse than it is either in lower orbits or in deep space.
- mikeash 8y agoThere are currently no manned vehicles capable of that trip. Probably the closest thing on the horizon is SpaceX’s BFR/Starship, which is proceeding at an amazingly fast pace, but no way is it ready to go in a year.
- ta345345453 8y agoHaha, yes imagine stuffing up the firewall rules on this one. "Bob, the intern fat fingered the port number, how do you feel about a bit of a sight-seeing trip?"
