Coming Up Live: Mike Griffin Says Farewell

NASA Administrator Mike Griffin will deliver what amounts to a farewell address to agency employees on NASA TV at the top of the hour, and you can watch the speech live here in The Flame Trench.

The address will come in the form of a NASA Update program at 11 a.m. from the agency's headquarters in Washington, D.C. Expect Griffin to reflect on the agency's accomplishments during his tenure in NASA's top job.

Griffin took the helm at NASA in April 2005 and lead the agency during the development of the architecture for Project Constellation, which aims to return American astronauts to the moon by 2020.

Griffin in recent weeks has said he does not expect to be kept on by the incoming Obama Administration and that he plans to leave NASA when his resignation becomes effective next Tuesday.

All Bush Administration political appointees working in the federal government tendered resignations after the presidential election as a matter of course.

Monday is a federal holiday and Tuesday is the inauguration, so today will be Griffin's last day at NASA Headquarters. He has no immediate plans other than to take a ski vacation.
