Cargo Shortfall for ISS When Shuttle Retired
ISS Panel Report, Integrated Space Operations Summit
“- Based on current requirements, the cargo vehicle flight rate after Shuttle retirement does not meet the projected re-supply and return needs of ISS
– Requirement reductions alone will not eliminate the transportation shortfall; additional transportation capabilities will be required
– With retirement of the Shuttle, the ISS faces a transportation shortfall based on current requirements
– The ISS Program should continue to pursue alternate means to deliver cargo to and from the ISS
– Exploration systems should pursue the use of the ISS as an engineering/science test bed to develop and prove the systems and crew health measures required for exploration beyond low Earth orbit”
