This will profoundly decrease the ability to conduct worId-ciass research in the microgravity environment of space. This report weighs the advantages and disadvantages of adcling annual Space Shuttle flights dedicated to microgravity research to ensure the continued viability of the microgravity research community.

Earlier ~ Adjustments to the NASA budget by the Administration have resulted in a reduction Tom previously planned Space Shuttle flight rate levels. All of the lighter weight Space Shuttles are fully dedicated to ISS assembly flights, leaving only the heavier Columbia to support NASA's other space access requirements via the Space Shuttle.

This picture is further clouded by the uncertainty surrounding the date of complete ISS assembly. If Assembly Sequence F is assumed, that ciate is in 2006.

It would be penny wise and pound foolish to substitute two-week Space Shuttle missions at a cost of significant delays to the readiness of the ISS to conduct microgravity research. Since current plans may call for the deleting or reducing the capability of the Centrifuge Facility, any actions that further impact funds would only exacerbate the Toss of microgravity research capabilities.
