【2018年5月24日】
老马公布了正在进行EMI测试的载人龙飞船。SpaceNews新闻表示NASA认为先上人再进行燃料加注在安全上是可以接受的。

NASA正在mockup中实际测试载人龙飞船

但外界普遍怀疑两家公司能如期进行飞行测试,预计载人飞行测试将推迟到2019年。美国政府问责局今年1月警告称,SpaceX可能要到2019年12月才能获得NASA向国际空间站运送航天员的资格认证,波音获得资格认证的时间更是可能会推迟到2020年2月。鉴于NASA与俄罗斯太空总署利用联盟号飞船运送航天员的合同将于2019年9月结束,NASA需要未雨绸缪。NASA今年早些时候表示,它计划使载人飞行测试执行向国际空间站运送航天员的任务,飞船在国际空间站的停靠时间将由数周延长至数月。

龙2空重16976磅/7.7吨
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.

龙2装有16台龙和8台超龙发动机
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.

龙2最多装有4885磅/2.2吨推进剂,其中包括3004磅/1363千克NTO和1881磅/853千克的MMH
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.
龙和龙2的典型重量在19840和33070磅之间(9吨到15吨),载人和货运龙2的重量区别不大
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.
