Requirement generation for the habitation extension module

As part of a debate within Great Britain regarding its policy to eschew human space flight, a study design was produced to explore the implications of a late entry as a full partner in the International Space Station (ISS). This objective generates many diverse requirements from thw two primary stakeholders, the existing ISS partners and Great Britain itself. It was found that a Soyuz/Fregat launched Habitation Extension Module with a logistic supply capability could meet all these requirements in a single objective and the flexibility inherent in the wide design space created by the many options have made it possible.
