All the references I found Wikipedia said it used Hydrazine thrusters.
As to why there's propellant left: it's a sealed system and NASA has intelligent engineering practices when it comes to resource planning.
- garmaine 9y agoNo seal is perfect, especially without standard pressure surrounding it.
- mrguyorama 9y agoThe fact that there is propellant left implies that the seals were good enough
- jacquesm 9y agoIf you wait for the perfect seal you will never launch. And it will cost you a lot of fish.
- qubex 9y agoHow could a rocket system, which when in operation vents reaction mass into the vacuum of space, ever qualify as a “sealed system”? Surely only the storage tanks could ever qualify as being a “sealed system”, and even then an imperfect one, because there must be one or more potentially leaky valves leading to the actual nozzle somehow?
