SpaceflightNow is reporting that NASA has decided to postpone launch one week.
Liftoff is now targeted for 4:41am EST, Thursday, February 19.

The delay is due to work needed to replace Flow Control Valves in Discovery's Main Propulsion System.

It looks like they were pushing it just a little too close and decided they better take a little more time.

Still due to FCV problem.

Quoting TheSonntag (Reply 7):

If they don't launch by mid-March (when they have to stand down to let a Soyuz fly to the Station), there will be a domino effect on subsequent launches.

If they delay until April or later, that will be a serious schedule problem, and could force cancellation of one of the last Shuttle missions if the Shuttle program isn't extended beyond 2010.

Increased threat of MMOD (micrometeoroid/orbital debris) impacts, which weren't low before the collision. Spacewalks are now a little more dangerous, and spacewalks are the one thing in spaceflight that are more dangerous than they look.

Nasa now seems to target March 12th as a planned date, but nothing has been decided yet. They wording implies that they want to prepare people for delays of the next missions, as well... Writing "we are not in a rush" (which is, of course, important) seems a bit unbelievable, with that in mind...

But go-fever would be the worst thing imaginable...

Nice to see em advance the date for a change.
I don't know if they've decided to let the Starboard SARJ run full out yet, but it will be nice to see the station looking balanced when S6 is on. I gather they'll probably just duct tape the extra race to the truss in case they need it someday, and probably not change out the damaged one if things keep going smoothly. I know they're also considering moving to the already installed spare race and keeping the used one for backup.

Delaying the launch a month to study a problem is "go fever"?  Confused

Of course not, but it seems that apart from that, they now try to continue very fast... I am no expert, though. My concern is just that they now run into schedule issues if they do not launch soon.

Why wait? Discovery herself has been ready to fly for over a month now while engineers ran tests on the little Flow Control Valves to make sure they didn't have cracks in them. Once the engineers say, "Okay, we're comfortable with this" and management said, "Okay, let's go fly..." it is essentially just a matter of starting the countdown.

NASA reportedly came very close to going ahead with the launch late last month, but decided to err on the side of caution and run another batch of tests on the FCVs. Those results came back this week.

Quoting Alessandro (Reply 23):

Well, launch times advanced about 25 minutes each day, so a one-day delay would be 23 hours and 35 minutes.

But I'm thinking this will be at least a two-day delay, due to ET draining and pad-safing needed before they can fix whatever leaked (which seems to be either on the pad's LH2 vent arm or at its attach point on the Tank) assuming they can find it quickly and the fix is not too involved.

Weather forecast was 90% 'go' for Thursday and 80% 'go' for Friday, last I heard.
