On July 2, 2018 at 13:50 UTC, the private U.S. unmanned supply spacecraft, the "Dragon” SpX-15 (CRS-15 flight), was successfully docked to the International Space Station. The linkup operation was carried out with the help of the giant 17-meter Canadarm. The capture with Canadarm-2 was performed by American astronaut Richard Arnold at 10:54 UTC. The Dragon spacecraft was maneuvered into position and attached to a berthing port on the space station's Harmony module by ground controllers in Houston and Canada. This docking marked the 15th time a Dragon spaceship has reached the space station, counting a demonstration flight in 2012.
