Some thoughts on space station science

US government proposals to cut the scientific budget of the ISS are placed within the historical context of the US space program. The author divides this into three phases-early days to the end of Apollo, the Shuttle era, and the Space Station era-and shows that all of these have suffered from decisions to reduce scientific capabilities. Even without cuts, it is unlikely that the Station can produce scientific outcomes that are commensurate with the investment that has taken place and it is imperative that policy makers learn from the lost opportunities of the two earlier phases if greater disappointment is to be avoided.
