A few hours ago, the SpaceX Dragon spacecraft ended its CRS-23 (Cargo Resupply Service 23) mission for NASA splashing down smoothly in the Gulf of Mexico, off the coast of Florida. The Dragon left the International Space Station a few hours earlier. For SpaceX, this was the third mission of the second contract with NASA to transport resupplies to the Station with the new version of the Dragon cargo spacecraft, which splashes down near the East coast of the USA instead of the Pacific Ocean.
