NanoRacks Commercial Space Station Airlock "Bishop" Completes Critical Design Review, Moves to Fabrication

Press Release From: Nanoracks
Posted: Tuesday, April 17, 2018

The NanoRacks Space Station Airlock Module “Bishop” met another major milestone with completion of the Critical Design Review (CDR) on March 20 and 21, 2018 in Houston, Texas.  This milestone begins the transition from the engineering design phase to the fabrication phase.  Detailed design drawings such as those for the critical pressure shell will be signed and released to NanoRacks fabrication partner, Thales Alenia Space, in order for them to continue their fabrication efforts.
 
In February 2018, NanoRacks announced that Thales Alenia Space, the joint venture between Thales (67%) and Leonardo (33%), was chosen as the latest partner in its commercial airlock program, joining with a number of key partners, including Boeing.
 
Thales Alenia Space is set to produce and test the critical pressure shell for the NanoRacks Airlock Module and will also manufacture various secondary structures, including the Micrometeoroid Orbital Debris (MMOD) shields with Multi-Layer Isolation (MLI) panels, the power and video grapple fixture support structure and other structural components.
 
Other key features, such as the Passive Common Berthing Mechanism (PCBM), being manufactured by Boeing, require a long lead time and have been in production for over a year now.  The PCBM will be delivered to Thales Alenia Space in May 2018 and will then be installed to the pressure shell.
 
 “I’m very proud of the NanoRacks engineering team and our partner, ATA Engineering, who performs the structural and thermal analysis for Bishop,” says Airlock Project Manager Brock Howe. “This is a crucial milestone that required many long hours, and the team has been working together very smoothly. We’re also very appreciative of our relationship with NASA and the International Space Station Program Office, as they have provided guidance and expertise in several critical areas. As always, there is plenty of work still to do – and we will continue to push forward.”
 
The next major milestone is the Phase II Safety Review scheduled for June 2018.  The project is still on track to meet the SpaceX CRS-19 launch, targeting fourth quarter 2019.
