At the moment everyhthing green, including weather. Hopefully it stays green...

 

[MeteorWayne]

Last I heard, weather was still only 30% go, but is currently green, so that's good. Problem is possible low ceiling.

 

[MeteorWayne]

Current In-Plane preferred time is 4:39:50 EST (9:39:50 GMT/UTC)

 

[bluegrassgazer]

NASA TV sounds a bit more optimistic about launch weather now.

 

[Testing]

Check Test. Damn Wx.

 

[MeteorWayne]

Hey if it can go from 80% go to 30% go, it can go back up as well

Currently is go (just confirmed again)

 

[EarthlingX]

Let's breathe reaaal slow, see if it might help ...

 

[earth_bound_misfit]

Sounds like a no go with cloud ceiling limit.

 

[MeteorWayne]

The weather situation is described as "dynamic"

 

[MeteorWayne]

Final poll, all is go except for range and RTLS weather. About 10 minutes to scheduled launch.

 

[bluegrassgazer]

Scrub

 

[earth_bound_misfit]

******, scrubbed at least 24hrs

 

[MeteorWayne]

Rats, weather scrub

 

[EarthlingX]

 

[MeteorWayne]

23.6 hour turn around, scheduled for ~ 4:14 AM EST (0914 GMT/UTC) tomorrow.

Now only a 60% chance of good weather tomorrow.

Wonder how this affects the SDO launch; checking now.

Ah ... I just went to NASA TV after being reminded by MeteorWayne about the launch in another thread, only to find it now isn't happening ... :?

Force is strong with you ..

Anyways .. no problem

Endeavour Launch Rescheduled

Managers officially have scheduled space shuttle Endeavour's next launch attempt for Monday, Feb. 8 at 4:14 a.m. EST.

The Mission Management Team will meet at 6:15 p.m. Sunday to give the "go" to fill Endeavour's external fuel tank with propellants. Tank loading would begin

Shame about the scrub, at least it was due to the weather, rather than technical issues. I will be at work for tomorrow's attempt, so will not be able to watch.

I will catch up later.

Below live camera 3 feed just downloaded. Yep Endeavour's still there. :shock:

Just downloaded camera 3 live feed. Looks like the Sun has come out.

Forecast:

A low pressure area off the northeast U.S. coast continues to move off to the east, and a high pressure area is building in from the northwest. A low-cloud ceiling remains prevalent across the area as cold air moves in from the northwest. A strong inversion causing the ceiling will weaken over the next 24 hours, but low-level winds near 3,000 feet will shift to the northeast Monday morning causing cold air stratocumulus clouds to migrate in from offshore. With the weaker inversion, the cloud deck should not be as wide spread as it was Sunday morning, but there is still a risk for a low-cloud ceiling."
The odds are set at 60 percent for acceptable weather, or 40 percent "no go" due to a low-cloud ceiling.
Similar conditions are expected on Tuesday morning too, forecasters say. "The concern for a ceiling continues as winds shift to the southeast and low-level moisture increases with an approaching cold front.
