Cygnus launch Sunday(12-6-15)

[Delta_8930]

Tomorrow the launch window will start at 5:10:35 pm EST.

If we are scrubbed tomorrow, then the launch window on December 6 will open at 4:44:53 pm EST.

[Mitchz95]

Actually, it looks like they're trying again tomorrow. Not sure what time.

EDIT: Ninja'd.

The 5:10 PM launch had better work. Has a launch ever been delayed this many times?

[Kryten]

80% chance of violation, currently. And I'm pretty sure shuttle reached the 5 scrub mark at least.

Why is it the time gets earlier each day? The Earths movement around the sun?

I think it's just the way the ISS's orbit matches up with where the launch site is.

I'm just guessing, but it's probably due to the ISS orbit period is not an exact multiple of one day. So when the launch site passes under the orbit path, ISS is in a different phase of its orbit, and they advance or delay a little to compensate. Again, I'm just guessing. Anybody know the real answer?

Launch scrubbed for today, new launch attempt tomorrow (6th December 2015) at 4:44pm EST. Weather 40% GO.

[Mitchz95]

Dang it, I'm gonna be stuck at work.

Why was it scrubbed again? 

Have there ever been this many scrubs for a launch?

[Kartoffelkuchen]

High-altitude wind violation. Don't know what's the record there.

[Delta_8930]

In the meantime, while we're waiting 24 hours for the launch, here's my version of the OA-4 launch, in KSP:

Don't get me started on STS-35

Oh god...that LH2 though...

[SuperFastJellyfish]

Under 3 hours until the 30 minute launch window opens.  Let's hope the weather is cooperative.

Why Didn't you launch to 51.6 degree inclination, the ISS isn't at 0 degrees inclination, or even 28.6 like from KSC/CCAFS.

Huh. Never thought about launching to an inclined orbit. I was a bit lazy and I just wanted to press "D".

[SuperFastJellyfish]

The stream is live.  Links in the op. 

[Mitchz95]

I'm stuck at work right now, so I'm counting on you guys to keep me updated.

[Delta_8930]

Go Atlas! Go Centaur! Go OA-4!

Favorable weather is currently 70%. Main concerns are ground winds and cumulus clouds. Everything is currently GO. We're about 30 minutes away from launch right now.

[SuperFastJellyfish]

Everything is go so far.  Cygnus is in the process of switching to internal power.

[Kerbal01]

launch is at 4:44.45 EST 21:44 UTC. 

[RocketPilot573]

4th time's the charm? Right?

[Kartoffelkuchen]

Countdown proceeds.

[viktor19]

We are out of the hold and currently at T-2:30!!

EDIT: Nominal liftoff, approaching max Q
