The mission, known as crs-21, is also the first time that the cargo dragon spacecraft has automatically docked to the international space station without using the Canadarm2 manipulator. According to NASA, this mission also marks the first time that two dragon spaceships have been docked with the international space station at the same time, because a manned dragon spaceship has also stopped here since it transported four astronauts to the international space station in November. < p > < p > the crs-21 dragon spacecraft is also the first spacecraft to return directly to the vicinity of Kennedy Space Center since the space shuttle officially retired in 2011. The cargo dragon spacecraft will bring a series of scientific experimental equipment back to earth. "After a SpaceX ship pulls the ship out of the water, a standby team takes the key scientific and technological equipment out of the ship and loads it onto a helicopter," NASA said. The helicopter will deliver the scientific data to the shore a few hours after the splash (Chenchen) < / P > < p >
