The flight of the reusable Discovery revived the nation's dreams of heroic astronauts exploring the solar system, but it did not restore the hopes of scientists that their space experiments will soon be in space. Scientists, by contrast, consider themselves among the casualties of Challenger. Only in recent months did NASA give in to the arguments of scientists that alternatives to the shuttle need to be found for their experiments.

To the surprise of many within NASA, who had braced for cuts in the fiscal 1989 budget, Congress in August 1988 reduced some social and environmental programs to give $10.7 billion for the space program.
