At the STS-119 mission management's morning news conference, the team reported the weather for launch is looking very good, and there are no technical issues unresolved. The next milestone in Discovery's preparation is fuel cell loading this afternoon at 3 p.m. EDT.

"We had a very short meeting today, which is a record for us for STS-119," said Mission Management Team Chair Mike Moses. "Today we transitioned from readiness to launch ops. We really didn't have that many issues to discuss."

"Yesterday the crew got in on time and are excited to be here. We started the countdown on time and the next major event is fuel cell load this afternoon," added Launch Director Mike Leinbach. "RSS retract is Tuesday night-Wednesday morning. We're not tracking any issues, so the team is anxious to go."

Kathy Winters, shuttle weather officer, gives Discovery a 90 percent chance of good weather for liftoff, and all the transatlantic abort sites will also have favorable weather.
