SpaceX CRS-17



Dragon is a space capsule designed by SpaceX to provide supplies to the International space station.

The Dragon spacecraft is made up of a pressurized capsule and unpressurized trunk used for Earth to LEO transport of pressurized cargo, unpressurized cargo, and/or crew members. Initiated internally by SpaceX in 2005, Dragon will be utilized to fulfill the NASA COTS contract for demonstration of cargo re-supply of the ISS.

The Dragon capsule is comprised of three main elements: the Nosecone, which protects the vessel and the docking adaptor during ascent; the Pressurized Section, which houses the crew and/or pressurized cargo; and the Service Section, which contains avionics, the RCS system, parachutes, and other support infrastructure. In addition an unpressurized trunk is included, which provides for the stowage of unpressurized cargo and will support Dragon's solar arrays and thermal radiators.

For this launch, the spacecraft’s pressurized capsule is loaded with 1,517 kilograms (3,344 lb) of equipment and supplies, while a further 965 kilograms (2,128 lb) of unpressurized cargo is stored in the spacecraft’s trunk section, for a total of 2,482 kilograms (5,472 lb).

The pressurized cargo includes 726 kilograms (1,601 lb) of scientific equipment and experiments. Research that CRS-17 will deliver to the station includes Tissue Chips in Space – an investigation that will use three-dimensional cultures of human tissue to study how cells respond to factors such as drugs or diseases in the microgravity environment.
