Good videos. 

Does anyone have that great X-37B video Boeing made?

Atlas V / OTV-3 launch video (GoPro and from the press site)
« Reply #202 on: 12/12/2012 03:15 PM »
Hey all, here are a couple videos I and my team captured from yesterday's Atlas / OTV-3 launch. The first one is from a remote GoPro Hero that was placed at the launch pad perimeter. The second is a video clip I shot from the press location near the ASOC. Enjoy!

Is it me or is the X-37B video giving more info than previously?

Well, unfortunately, for this mission I haven't seen any pictures of the launch preparations of the X-37B vehicle (I checked ULA, Boeing, USAF and Patrick AFB, and various websites with space news)...

OTV-3 has already been spotted by satellite hobbyists based on Ted Molzcan predictive elements.

After initial confusion regarding interpretation of observations, Ted has a new set of elements which should be close. Further observations will firm them up.

If this TLE is correct, and there is no reason to doubt Ted's excellent work, the inclination of 43.4966 was easily reachable directly from the Cape.  Why was the dogleg maneuver mentioned in the live broadcast necessary--or desirable?

New camera? Doesn't seem to capture the rumble nearly as well as your older launch videos do.

more details from the program AFRCO
http://www.af.mil/news/story.asp?id=123329533

"We couldn't be more pleased with the strides we've made in this program and the success of the X-37B vehicle on the first two flights," said Mr. Richard McKinney, Deputy Under Secretary of the Air Force for Space. "However, it is important to keep in mind that this is an experimental vehicle and a third mission is still relatively young for a test program. This is the first re-flight of a vehicle so that is certainly a key objective for us. We have only just begun what is a very systematic checkout of the system."

Secretive Space Plane's Retro-Burn Snapped By Satellite Hunter | video

Published on Dec 14, 2012

Greg Roberts captured footage of a fast moving cloud above over Cape Town, South Africa, created by the retro-burn of the 2nd stage Centaur rocket that launched the robotic X-37B space plane.

...Why was the dogleg maneuver mentioned in the live broadcast necessary--or desirable?

They launched southward so they had to avoid overflying the Caribbean islands.  The NOTAMs for the stage drop zones were on a ground track heading of about 110 degrees; about a 126-degree azimuth would have been needed to go direct to the 43.5-degree orbital inclination.

I have a question, that confuses me a bit:
At about 0:35 he writes: "The cloud was first thought to be a fuel dump by the 2nd stage Centaur rocket, but later shown to be a retro-burn of both objects as can be seen in this video taken by Greg Roberts."
Does this make any sense?
Since he mentions Centaur and OTV-3 as the two objects earlier in the video, I assume he wants to tell us that OTV-3 made a retro-burn as well.
But how could that be? Why would OTV-3 do a retro-burn so soon after launch? It did not land already, did it?

retro burn was the wrong terminology to use.

Thanks! What would be the right terminology then?

It did any of the following:
a thruster firing
a burn
an orbital adjustment
a phasing burn
a sep burn
a thruster checkout
an OME burn/firing
a maneuver

Having no luck tracking OTV-3 anymore on http://www.n2yo.com/satellite/?s=39025

Has anyone tracked any orbit corrections?

Thanks
