STS-119 Delayed

Shuttle mission STS-119 to the International Space Station has been delayed again. This mission will deliver the final set of solar arrays to ISS. Possible problems with flow control valves have delayed the mission from February 12 to February 19, 27 and now to an indeterminate date. If the delays stretch past March 12, STS-119 will have to be indefinitely delayed to make room for a Soyuz flight later in the month. The delay most affects Sandra Magnus aboard ISS, for STS-119 is her ride home.
