火箭:Falcon 9 Block5
载荷:载人龙飞船(Crew Dragon)
轨道:LEO,ISS(400 x 400 km, 51.64°)


Dragon-2 weighs
approximately 16,976 pounds without cargo, with a height of approximately 2,317 feet (including the
trunk) and a base width of 13 feet. Each pair of SuperDraco engines (eight total engines) are mounted to
a monolithic aluminum bracket. This bracket is connected to the pressure vessel with three mounts in a
minimally constrained fashion.

There are 18 Draco RCS engines and 8 SuperDraco LAS engines
(two in each for the four modules) on the Dragon-1. There are 16 Draco RCS engines and 8 SuperDraco
LAS engines (two in each of the four modules) on Dragon-2.

The Dragon-2
could contain up to 4,885 pounds of propellant which includes 3,004 pounds of NTO and 1,881 pounds
of MMH.
Dragon would typically weigh between 19,840 and 33,070 pounds
based on the mission specific profile. Dragon-2 would also have the capability of returning astronauts to
Earth. The weight differential between a cargo and crew mission would be negligible




At NASA Kennedy Space Center’s Launch Complex 39A, the nine engines of a SpaceX Falcon 9 rocket roar to life in a brief static firing on Jan. 24, 2019. The test was part of checkouts prior to its liftoff for Demo-1, the inaugural flight of one of the spacecraft designed to take NASA astronauts to and from the International Space Station. NASA has worked with SpaceX and Boeing in developing Commercial Crew Program spacecraft to facilitate new human spaceflight systems launching from U.S. soil with the goal of safe, reliable and cost-effective access to low-Earth orbit destinations such as the space station.

Moreover, the avionics bay for the DM-1 Dragon is fully populated and is going through checkouts. All cabin support equipment and propulsion components are installed. Final installation is also underway on the ECLSS (Environmental Control and Life Support System) as well as the oxygen and nitrox delivery panels.
As far as the crew dragons ability to generate its own power, 120 of the 240 solar arrays have been completed and are in the process of being installed onto the DM-1 vehicle. Overall, the docking system build for DM-1 is 90% complete and underwent testing at the Johnson Space Center prior to being installed on the vehicle for flight.
At this point, the crew Dragon for DM-1 will be shipped to Plum Brook Station for environmental testing at the end of May.
