Another Launch Delay

NASA has delayed the launch of space shuttle Discovery yet again. Now, the earliest date to fly is February 27. The problem remains questionable fuel valves. Tests on the valves are being conducted.

The delays are beginning to threaten future shuttle launches. If Discovery doesn't go by March 12, it will have to wait until at least March 26, to allow for a Soyuz mission to ISS. At that point, delaying future shuttle missions would likely have to be considered.
