On March 3, 2019 at 10:51 UTC, the unpiloted “Crew Dragon” (or “Dragon-2”) spacecraft (Mission Demo-1 or SpX-X-DM1) successfully docked to the International Space Station. It is the first docking of the “Crew Dragon” (“Dragon-2”) with the ISS. The “Crew Dragon” docked to the forward port of the “Harmony” module, which had been fitted with an International Docking Adaptor (IDA). The IDA was delivered to the Station by the “Dragon-1” spacecraft (SpaceX CRS-9 mission) in July 2016. The Demo-1 mission marks the first flight of the new and improved “Dragon-2” spacecraft, which is longer and more massive than its “Dragon-1” predecessor.
