Our seed corn is research and development. We do not want to ever give that up, and that is the mission of NASA.

It is a real problem, and we are going to have some catastrophic consequences if we cannot get nations that are launching things into space to provide enough fuel to have a controlled reentry.

We cannot operate our science agencies on the cheap, and we should not operate them without clear, multi-year direction.
