This is the first launch for this redesigned cargo Dragon, and also the first mission for SpaceX's new series of CRS missions under a renewed contract with NASA. It is carrying 6,400 lb (2,900 kg) of both supplies for the Space Station and its crew, as well as experimental supplies and equipments for the research being done on the Station. This version of Dragon can carry 20% more than the last cargo spacecraft from SpaceX, and it also has twice the number of powered lockers for climate controlled transportation of experimental material.[37]
