In the early 1980s it had been NASA policy to promote the use of the Space Shuttle for almost all launches, both civilian and military; only then, with Shuttle missions taking off almost every week, would the Space Shuttle program make economic sense. However, the "Challenger" disaster in 1986 forced a reconsideration, and in the following years many studies attempted to chart a way forward without reaching any consensus except for a growing feeling that "faster, better, cheaper" would be a good idea. There was also disagreement over the design (and indeed purpose) of the proposed Space Station "Freedom".
