NASA may push back plans to launch its next shuttle mission until March 2006, allowing engineers more time to solve an ongoing foam shedding problem with orbiter external tanks.

What a mess. The formal report of the "60 day study" is due out this week. The new launchers being kicked around are so much simpler than STS that I could almost imagine it flying by 2010 if they could start working on it now.

I think that the possibility is growing that the next flight may be the last.
