And scrubbed due to faulty hydraulics.

I believe that is the last L-1011 flying, unless I am mistaken.

One of the last eight, according to the ever reliable Wikipedia. Half of those are with Barq.

Yup, next launch attempt is tomorrow I think. Not sure of the time yet

8:34 AM (I think). Not sure which time zone though. I assume the one Florida is in.

They're having to ship in a replacement part for the hydraulics system, so tomorrow isn't doable. It's currently NET the 14th.

On a more serious note, I hope that NASA can fix 'em up for a second launch attempt. I really want those CYGNSS satellites up.

Yep, problem with the arm release, also there was a Weather RED during nearly all the launch, some CB all around. Also they were talking about a new attempt for today (16/12/13) with a window between 13:19 - 14:19 UTC for some times, but they finally have to send new pieces from Mojave.

Despite all the bad thing that is said about it and its rare launches Pegasus stays an exceptional vehicle.

 

 

 

If some of you are interested Matthew Travis had put on line a video about the payload objectives :

And here´s one on youtube: (the one on spaceflight now isnt working for me)

Interesting angle of attack.  Anybody know the angle they are shooting for and what a pegasus "gravity turn" looks like?  Starting at ~10,000m (L-1011 ceiling listed at 12-13km) changes things a bit.

I swear you that the last minutes were absolutely terrible. It was the first time since Orion EFT-1 in 2014 that I wake up an hour before for seeing a live retransmitted launch (07:00 while I came back from the work at 01:15...), everything was going well then during the countdown last seconds it comes like that : ...6 ...5 ...4 ...3... wait, wait, wait! Arrrrh nooooo, not again! Finally they restart it about a minute later and everything went well.

As it was dropped from more than 10 km it's still impressive to see how fast it past the 100 km border.
