The cannister fillers allow you to create 25kg bottles at a time, and require dupe interaction to do so. If you build a rocket platform, any engine, then replace the engine with a gas cargo tank, plus of course a rocket port loader, you have a cannister filler that produces 11t bottles without dupe interaction.
Using the new move to-command, you can use this to bring 11t bottles of oxygen along with you to oxygenate a fresh base on a new planetoid, using the cannister emptier. 11 tons will last many cycles. Also you don't need to wait the stupidly long times for these to fill when you build them on the real rocket, which could be flying again instead of waiting on the rocket platform.
How much strength would that take?
Assuming both carrying skills and 200kg starting capacity, +240 strength total.
Lol that's an insane number, that would require a mod I imagine.
