SpaceX CRS-13, also known as SpX-13, was a Commercial Resupply Service mission to the International Space Station launched on 15 December 2017. The mission was contracted by NASA and is flown by SpaceX. It was the second mission to successfully reuse a Dragon capsule, previously flown on CRS-6. The first stage of the Falcon 9 Full Thrust rocket was the previously flown, "flight-proven" core from CRS-11. The first stage returned to land at Cape Canaveral's Landing Zone 1 after separation of the first and second stage.
