NASA SpX-17 mission patch
SpaceX CRS-17, also known as SpX-17, is a Commercial Resupply Service mission (CRS) to the International Space Station that is currently scheduled to launch on April 30, 2019 aboard a Falcon 9 rocket. The mission was contracted by NASA and is flown by SpaceX.
In February 2016, it was announced that NASA had awarded a contract extension to SpaceX for five CRS additional missions (CRS-16 to CRS-20). As of June 2016[update], a NASA Inspector General report had this mission manifested for October 2018, but by January 2019 this had been pushed back to April 2019.
Due to Dragon 2 test anomaly on April 20, 2019, SpaceX acquired a permit to allow landing to drone ship just 28 kilometres (17 mi) downrange "to ensure the integrity of the area and preserve valuable information". 
NASA has contracted for the CRS-17 mission from SpaceX and therefore determines the primary payload, date/time of launch, and orbital parameters for the Dragon space capsule. According to a 2016 presentation, the external payloads manifested for this flights were Orbiting Carbon Observatory 3 (OCO-3) and STP-H6.
