NASA and Alliant Techsystems (ATK) of Salt Lake City, UT, agreed to collaborate on the development of the company's Liberty Launch System as part of the agency's Commercial Crew Development Round 2 activities. The unfunded Space Act Agreement through NASA's Commercial Crew Program will allow the agency and ATK to review and discuss Liberty system requirements; safety and certification plans; computational models of rocket stage performance; and avionics architecture designs. The agreement outlines key milestones including an Initial System Design review, during which ATK will present to NASA officials the Liberty systems level requirements, preliminary design, and certification process development. NASA will provide feedback to ATK based on its human spaceflight experience for advancing crew transportation system capabilities and the agency's draft human certification requirements.
