摘要

The American Astronomical Society (AAS) recently released a statement expressing concern over budget actions taken by NASA's Science Mission Directorate. However, the purpose of my comments here is not the AAS statement, so much as the underlying issues that led to NASA taking the actions that it did, and the potential effect those actions will have on the nation's future economy and security. NASA's actions were the result of a very real budget crunch, one that put NASA managers in a difficult position. There are several reasons for that crunch in my view, but two deserve special mention; congressionally directed funding, also known as earmarks; and the cost and pace of NASA science missions.
