A SpaceX Dragon cargo spacecraft docked with the International Space Station on 15 October, NASA reported. The mission delivered more than 6,300 pounds of research equipment, supplies and hardware after launching on 13 October.
The cargo included the final set of roll-out solar arrays intended for later installation. Research payloads included work related to retinal manufacturing and heart-tissue models, adding to experiments conducted aboard the station.
Docking confirms that the spacecraft reached the orbital laboratory. It does not mean the new arrays were already installed or that the research had produced clinical results; unloading, installation and scientific work are subsequent stages of the mission.
