Hawthorne, Calif. (SpaceX PR) –Recently, SpaceX completed another important milestone – the first NASA Crew Trial, one of two crew tests as part of Space’s work to build a prototype Dragon crew cabin.

For this milestone SpaceX demonstrated that our new crew cabin design will work well for astronauts in both nominal and off-nominal scenarios. It also provided our engineers with the opportunity to gain valuable feedback from both NASA astronauts and industry experts.
The engineering prototype includes seven seats as well as representations of crew accommodations such as lighting, environmental control and life support systems, displays, cargo racks, and other interior systems. During the daylong test, SpaceX and NASA evaluators, including four NASA astronauts, participated in human factors assessments which covered entering and exiting Dragon under both normal and contingency cases, as well as reach and visibility evaluations.

The seven seats mount to strong, lightweight supporting structures attached to the pressure vessel walls. Each seat can hold an adult up to 6 feet 5 inches tall, 250 lbs, and has a liner that is custom-fit for the crew member.
In fact, Dragon has so much interior volume, that we could place an entire three-person Russian Soyuz capsule descent module inside Dragon’s pressure vessel.
Stay tuned for more updates as we work towards making Dragon the most advanced spacecraft ever flown.
