Elon Musk's rocket company made NASA history Friday, as SpaceX became the first company to launch a resupply mission to the International Space Station on a reused rocket.
The mission, known as Commercial Resupply Services 13 (CRS-13), launched from Cape Canaveral Air Force station in Florida on a Falcon 9 rocket previously flown for CRS-11 in June this year.
It is the first time NASA has approved such a mission and the fourth time SpaceX has launched with what it says is a "flight proven" booster. Three commercial missions earlier this year, including the record turnaround from BulgariaSat-1 in June, have reused Falcon 9 rockets.
NASA officials announced the CRS-13 would be on a previously flown booster, saying in a press conference before the launch that the administration is "very comfortable that the risk posture on this vehicle is not significantly greater than a new booster."
This was the only launch where NASA has approved the use of a previously launched rocket. SpaceX demonstrated thorough readiness for the rocket after NASA participated "in a broad range" of date assessments and inspections of the Falcon 9.
The launch had been delayed multiples times from its original December 8 target, with today marking the last backup opportunity until December 25.
The 45th Space Wing of the U.S. Air Force said in a tweet before the launch that this was the 19th launch from Cape Canaveral's Eastern Range this year.
@45thSpaceWING: T-60 We are just 60 minutes away from our last space launch from the Eastern Range for 2017! This mission will be our 19th launch this year and bring our all-time total to 3,565 space launches since 1950!
