Manifesting Challenges effecting ISS Operations • 2008/2009 – 6 person crew (requires 4 Soyuz vehicles per year) • 2010 – Shuttle retirement • 2010 – 2016ish – Up mass availability per year • 4 Progress vehicles (NASA has manifested about 400kg on 3 2006 Progress vehicles) • 2? ATVs (½ the manifesting space of a progress?) • 2? HTVs (½ the manifesting space of a progress?) – Down mass availability per year • 4 Soyuz vehicles (NASA has manifested 20kg on 11S return and 30kg on 12S return) – 16 of 17 TLDs are being returned on 11S in a few days (0.01kg) • Operations/Science Investigations – Hardware build and burn philosophy post Shuttle retirement – Should integrate operations/science investigations and limit/eliminate duplication of hardware between International and Science Investigators • Stowage – Increasing problem onboard since Columbia accident – Current stowage is above operational limits but below crew habitability and safety limits – Stock piling of used hardware awaiting return on Shuttle flights – After Shuttle retirement this is not possible
