ISS Inflatable Hab Overview
What is the Inflatable Hab?
The Inflatable Hab is a light weight inflatable
habitation module for space applications
Original concept for light weight module as transit
module for future exploration
Proposed to the International Space Station (ISS)
Program as a replacement for the current Hab

Inflatable Hab
Proof-of-Concept Test Program
Challenges
Demonstrate the inflatable technology
Build a full size inflatable module
Develop the ISS Inflatable Hab architecture and
verify Inflatable Hab integration to space station
Inflatable Shell ‘98 Development Plan
Verify by test structural integrity of the load bearing restraint
layer
Two structural development articles tested in the Sonny Carter Neutral
Buoyancy Laboratory pool
Demonstrated structural layer to 4 atmospheres (4 times the operating
pressure) in September 1998 (vs. 2 atmospheres for typical aluminum
module)
Verify by test the folding, packaging, and deployment of the
inflatable shell in a space environment
Built full scale development unit with multi-layer shell and folded and
packaged the unit as if for flight
Demonstrated deployment in space simulated environment (in JSC’s
thermal vacuum Chamber A) in December 1998
