Last shuttle mission could be delayed until fall of 2011

If Congress does end up appropriating money for that last extra shuttle mission, NASA managers are considering delaying it as long as possible, until the fall of 2011. Key quote:

[Shuttle Program Manager John] Shannon said if the shuttle is retired prematurely, the ISS will not be properly supplied.

In other words, Congress and the President should never have retired the shuttle in the first place, at least not until a replacement was ready to go.

Soyuz undocking at ISS delayed

The scheduled return of three astronauts on a Soyuz spacecraft has been delayed tonight because of a malfunction in the docking port.

Update: The return to Earth has definitely been canceled for tonight. The problem was caused when latches on the Soyuz, designed to secure it safely to ISS, refused to release on command. As of 12:43 am the plan was to recycle and try to land on Friday evening.
