Today SpaceX launched its first reused rocket for NASA. Both the Falcon 9 rocket itself and the Dragon capsule have been used prior to this resupply mission. Back in June, Elon Musk's spacefaring venture put a reused capsule in orbit, but this trip to the International Space Station marks the first time that NASA has used a "flight proven" booster on a mission (read: reused) according to CNBC. Based on the livestream, everything seems to have gone well: SpaceX successfully landed the rocket, which means it could potentially make its third flight in the future.
