After I returned, I had the opportunity to join the NASA Advisory Council, as chairman of its Technology and Innovation Committee. The Council has recently been shaken up, with its membership reduced from 50 to 10 and each member's role clarified.
回国之后我有幸加入了美国太空总署（NASA）的顾问委员会，并担任了委员会下属的技术和创新委员会主席。该委员会最近发生了大变动，其成员人数从50个减少到10 个，而且每个成员所承担的角色都得到了明确。但委员会的实际权力依然是受限制的：太空总署按美国国会的指令运作，并受其资助。我们能做的只是对国会的指令和资助方向提供咨询意见。
