About the NanoRacks Airlock
2
• The NanoRacks Airlock Module is our next generation ISS payload facility and it builds upon NanoRacks successful NanoLab Modules, NanoRacks CubeSat Deployers, External Platform and Kaber Deployer
• An enabling system to provide additional capability for future utilization of ISS - both commercial and government use
• Provides additional airlock capacity for deployment satellites from ISS, housing experiments, and the ability to move equipment inside to outside ISS

• Commercial development • NanoRacks is the leading technical team to execute
this project • Internal funds, customer down payments, and investor
contribution is financing the project • NanoRacks will own the facility for it’s lifetime • Non-Reimbursable Space Act Agreement (OZ-16-047)
with NASA to develop the Airlock • Change Request 15277 approved by the SSPCB to
integrate the Airlock to the ISS • Targeting mid-2019 launch

Boeing Contract - Prime Vendor & Partner
Passive Common Berthing Mechanism
• Key interface to International Space Station (ISS)
P
Access to Boeing Engineering and Technicians
• Prime contractor to NASA and ISS for engineering
• Used for PCBM installation and risk reductions for technical issues
R
Hardware Contract
• For PCBM and additional engineering services
@
Commercial Space Leadership
• Participation with NanoRacks, the recognized commercial leader in low-Earth orbit
• Period of performance goes through ISS lifetime and extends if Airlock is used on future commercial space stations

Building a Bigger Gateway to Space

• Current bottleneck at the JEM Airlock • Limited size (~25 ft3, (0.70 m3)) • Only ~10 openings per year with the
restrictions on who uses these openings • NanoRacks Airlock will expand those capabilities
• Over 5X the volume (~141 ft3, (3.99 m3)) • Number of openings driven by commercial
market and ISS availability (4-8 times per year expected)

• The Nanoracks Airlock Module will be able to deploy much larger satellites that currently available through the JEM Airlock
• Our Airlock will be able to increase throughput by deploying up to 4 small satellites per Airlock sortie (opening) versus just one at a time through the JEM Airlock

Tech Demo with the Airlock
• Payload exposure to space environment for short duration (~1-2 weeks) • Infinite pointing options while on the SSRMS (e.g. Ram, Wake, Zenith, Nadir) • Examples: Earth viewing cameras, materials exposure, space construction,
sensor validation

Internal Payloads in the Airlock
• Typical internal ISS Rack/Locker type payload • Similar electrical interfaces as ISS Racks • Can operate in ISS environment (Node 3 hatch open)
or in various pressure conditions down to vacuum (Node 3 hatch closed)
• Examples: Locker payloads, glove box payloads, NR Frame payloads, custom size internal payloads

Payload Interfaces• Deployable payloads
• Mechanical: Clamp Band Opening Devices (CBOD) - NanoRacks Separation System or similar commercial variant
• Maximum size: 3.6x3.6x4.1 ft; 710 lbs (1.12x1.12x1.27m; 322 kg) • Based on max rectangular volume and max ballistic number
required by NASA for deployable payloads to minimize risk of recontact
• Internal Payloads • Mechanical: Interface to Airlock seat track (or NanoRacks develops) • Power: 120 VDC (4 sites internal) • Data: Ethernet to Airlock avionics
• Airlock communicates to ISS JSL • Store and forward capability with Airlock Network Attached
Storage

External Payloads
• Six external payload sites available • Oceaneering GOLD 2 connector provides electrical,
mechanical, and robotic interface • Roughly ~8 ft3 (0.22 m3)volume for payloads (~2 ft;
(0.61m) cube) • Redundant power (120 VDC) and data (Ethernet)
interfaces connected to Airlock avionics • Scarring for fiber optics and coaxial connections • Payloads could utilize a combination of internal
volume (e.g. for avionics) and external sites (e.g. for sensors)
