Additional verification and demonstration activities, which include five crew loading demonstrations of the Falcon 9 Block 5, will be critical to final certification of this plan. These loading demonstrations will verify the flight crew configuration and crew loading timeline prior to Demo-2. After these conditions have been met, NASA will assess any remaining risk before determining that the system is certified to fly with crew.

If all goes according to plan, on launch day, the Falcon 9 composite overwrap pressure vessels, known as COPVs, will be loaded with helium and verified to be in a stable configuration prior to astronaut arrival at the launch pad. The astronauts then will board the spacecraft about two hours before launch, when the launch system is in a quiescent state. After the ground crews depart the launch pad, the launch escape systems will be activated approximately 38 minutes before liftoff, just before fueling begins. SpaceX launch controllers then will begin loading rocket grade kerosene and densified liquid oxygen approximately 35 minutes before launch. The countdown and launch preparations can be stopped automatically up to the last moment before launch. In the unlikely event of an emergency at any point up to and after launch, the launch escape systems will allow the astronauts to evacuate safely.


额外的验证和演示活动,包括Falcon 9 Block 5的五次船员装载演示,对于该计划的最终认证至关重要。这些装载演示将在Demo-2之前验证飞行机组配置和机组装载时间线。在满足这些条件后,NASA将在确定系统被认证与机组人员一起飞行之前评估任何剩余风险。

如果一切按计划进行,在发射当天,Falcon 9复合外包装压力容器(称为COPV)将装载氦气,并在宇航员到达发射台之前验证其处于稳定状态。然后,当发射系统处于静止状态时,宇航员将在发射前约两小时登上宇宙飞船。在地勤人员离开发射台后,发射逃生系统将在升空前大约38分钟启动,就在加油开始之前。然后,SpaceX发射控制器将在发射前约35分钟开始装载火箭级煤油和致密液态氧。倒计时和发射准备工作可以在发射前的最后一刻自动停止。在发射前后任何时候发生紧急情况的情况下,发射逃生系统将允许宇航员安全撤离。











To me this confirms SpaceX are ahead on commercial crew program and will probably launch crew first.






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


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.
