Though on the flip side, I think there's a legitimate cause to want to use the combined action to jump out and get the supplies at Laurion, then not go back into the rover.
There's two paths that are very similar in difficulty and I'm not sure which is better:
- Jump out, get the supplies, get back in the rover, install the generator in Laurion, fuel it, stop the emergency power drain, go back out and park the rover
- Jump out, get the supplies, go into Laurion, drain a battery into the Laurion power grid, stop the emergency power drain, go back out and park the rover, install the generator in Laurion, fuel it
So far I've been deciding which path to take based on whether I ultimately want the power to stay in Laurion (to use for mining the Obelisk) or to go into charging the Rover.
