SpaceX CRS-11, SpaceX's eleventh CRS mission, was successfully launched on 3 June 2017 from Kennedy Space Center LC-39A, being the 100th mission to be launched from that pad. This mission was the first to re-fly a recovered Dragon capsule that previously flew on CRS-4 mission. This mission delivered 2,708 kilograms of cargo to the International Space Station, including Neutron Star Interior Composition Explorer (NICER). The first stage of the Falcon 9 launch vehicle landed successfully at Landing Zone 1. This mission launched for the first time a refurbished Dragon capsule, serial number C106, which had flown in September 2014 on the CRS-4 mission, and was the first time since 2011 a reused spacecraft arrived at the ISS. Gemini SC-2 capsule is the only other reused capsule, but it was only reflown suborbitally in 1966.
