This NASA JSC solicitation - "ISS Return Vehicle Pressure Vessel" - recently appeared on the Federal Business Opportunities website.

The statement of work is here:
http://procurement.jsc.nasa.gov/NNJ11396761L/ISS_RV_SOW.docx
This Statement of Work (SOW) is for the Design and Development, Procurement and Fabrication, Qualification and Delivery of 5 metal-lined, composite over-wrapped pressure vessels. The Contractor shall furnish all personnel, facilities, equipment, materials and services necessary to accomplish the design, development, testing, fabrication, assembly and delivery of 5 pressure vessels in accordance with Tasks 1 to 7.
Does anybody have any idea what this is about? Is JSC working on a pressurised ISS return vehicle?

A little bit more info from modification 1 to the synopsis:
https://www.fbo.gov/index?s=opportunity&mode=form&tab=core&id=f9e497edac3f7e78fcf6a8e7013ef64c&_cview=0 (https://www.fbo.gov/index?s=opportunity&mode=form&tab=core&id=f9e497edac3f7e78fcf6a8e7013ef64c&_cview=0)
The purpose of this modification is to answer the following questions below:
[...]
Question 1: Can you describe the specific usage of these pressure vessels in the ISS?
Answer 1: They are for cold-gas propellant storage for payload return propulsive capability.
Not clear if the "return" is just for disposal of payloads, or for something more than that.

I bet it is for ISS makeup air.

Wouldn't N2O be better for that?
