Building a Bigger Door to Space
3
• Current bottleneck at the JEM Airlock
• Limited size (~25 ft3, (0.70 m3))• ~10 openings per year with
restrictions on who uses those openings
• NanoRacks Airlock will expand those capabilities
• Over five times the volume (~141 ft3, (3.99 m3))
• Number of openings driven by commercial market and ISS availability

Concept of Operations
• Launch• SpaceX Dragon• Airlock in Dragon Trunk• No plans for hardware in soft stowage
• Installation• SSRMS ops from Dragon trunk to Node 3 Port Port - Ground• Berthing and CBM ops – Ground
• First installation utilizes CBCS system• Pressurization and Leak checks (via Node 3 ports) – ISS Crew
• Utilizes ISS resources for pressurization through equalization valve on hatch (first pressurization only)
• Hatch opening – ISS Crew• Centerline Berthing Camera Target removal – ISS Crew• Avionics cable hook up – ISS Crew• Ventilation system hook up – ISS Crew
• Activation and Commissioning• CDHS & EPS activation, Systems commissioning• Performed by NanoRacks Operations personnel• NR interface to ISS Ops via MCC-H• NR will monitor Airlock Systems after commissioning

CBCS Target
• Initial berthing to be performed using the CBCS Target System
• After hatch opening, target to be removed by the crew and stowed onboard in case of need for future use
• CBCS target and support structure can be broken down into a smaller more stowable configuration
• Future berthings will be performed using SSRMS digital data

NanoRacks “HayBale” Deployable Cubesat Dispenser (144U capability in configuration shown)
“HayBale” is deployed from NanoRacks Airlock in similar fashion to ESPA/Kaber type satellites, using NRSS or
Lightband. NanoRacks Airlock is then re-berthed to ISS. Once adequately separated from ISS, the orbiting
“HayBale” deploys pairs of cubesats over time until deployments are complete. Empty “HayBale” orbit
degrades and “HayBale” is destroyed upon re-entry.
