Don't seem to have a thread for this one, so opening with ULA's first e-mail about it showing the launch artwork:
-
Ooh, 2nd Atlas with a single SRB?
-
Should be a treat to watch it on liftoff!
-
Ooh, 2nd Atlas with a single SRB?
Third.

Trumpet F/O with the third SBIRS HEO element presumably.

Any word yet on the launch window?

Any word yet on the launch window?
I have seen a suggestion that the launch time is April 13 (GMT) with preferred lift off time of 0451 GMT and a window from 0451 to 0551 GMT. So local launch time April 12, at 20:51 PST
(correction from an earlier post)
-
Except the US is on Daylight time, so 21:51 PDT/local - if your suggestion is based on GMT.

Yes, you're absolutely right - I forgot about clock changes! The GMT times are the basis.
Thanks for catching that.

ULA:
UPDATE - April 8, 1 p.m. PDT: The launch of an Atlas V carrying the NROL-34 payload has been rescheduled for April 14, 2011, in order to allow time for the launch team to replace an avionics component on the vehicle. The launch is now scheduled for April 14 from Space Launch Complex-3 at Vandenberg Air Force Base, Calif. The opening of the launch window is 9:24 p.m. PDT.

Is anyone besides me missing the good old days, back when secret satellites were launched without fanfare, inside plain, unadorned payload fairings? ;)

Looks like this launch date has a shorter window of only 29 minutes (9:24 to 9:53 pm PDT) compared with 1 hour previously for April 12.
-
Probably just giving a little more public fidelity of the actual launch window instead of the launch period. This has been done for most NRO launches.
-
Does anyone have word on launch windows if they scrub Thursday?

ULA:
Everything continues to go well as we progress towards the launch of Atlas V NROL-34 on Thursday night. The launch time is set for 9:24 p.m. PDT. We’ve had a bit of a change in weather, with the possibility of high wind gusts during MST roll and into the launch time. In terms of wind constraints, it is now looking like a 30% chance of acceptable weather for launch. The winds look the same for an attempt on April 15 as well.

ULA:
We are almost 4 hours from the launch of Atlas V NROL-34 from Space Launch Complex-3. We have just received the OK to roll the mobile service tower (MST) back and the operation will be complete within the hour. Winds are still a concern at T-0, but they are expected to begin to die down around 7 p.m. PDT. The weather officer is reporting a 30% chance of acceptable weather for launch.

ULA:
Entered the first of the planned holds about 15 minutes ago.

Thanks! Because it was only a flash stream, all the screenshots I was taking was the old fashioned way of print screen, into MS Paint, crop, save and publish. Pain in the bum I can tell you! :D

Sorry :( If I'd known that I woulda helped ya. I didn't know if I could keep up if I did that.
-
Good looking rocket.
Not the first time you've said that. Fan of the Atlas V?
-
Beautiful flight from SE of LA. Passed through setting Orion just north of the Belt. Centaur ignition seemed to be a large orange cloud that dissipated very quickly.
-
Not a problem, Northanger.
Fan of all LVs Jason.....but I do like the Atlas V. Probably second only to Shuttle. Very nice looking vehicle, and it this one had its own charms with the single booster :)
-
Couldn't have asked for a clearer night in LA! It was beautiful. Very nice climb and exhaust plume was very visible (even more so than L-41). Viewed staging & then centaur ignition. After that it disappeared.
Great job to the ULA/VAFB/NRO Team after yet another successful launch!!
-
Very noticeable!
Thanks for the coverage Chris.

WOW!!!

That's great how it lights up the condensation and ice falling off it. Needs one of those MaxQ videos 8)

Job well done ULA!!!

There's an idea. Atlas V needs a Shuttle-style MaxQ rock video and another of Chris' "OMG, that's hardly my taste in music" suggestions ;D

ULA presser:
ULA Successfully Launches Fifth NRO Mission in Seven Months
Vandenberg Air Force Base, Calif., (April 14, 2011) – A United Launch Alliance Atlas V rocket carrying a payload for the National Reconnaissance Office (NRO) lifted off from Space Launch Complex-3 here at 9:24 p.m. PDT today. Designated NROL-34, the mission is in support of national defense.
Today marked the 25th Atlas V rocket launch in program history. The first Atlas V launched in August 2002. Since then, Atlas V has launched a variety of payloads for the military, NASA, and commercial customers, all successfully.
“Today’s successful launch of the NROL-34 mission represents a tremendous accomplishment for our national security customer,” said Jim Sponnick, ULA vice president, Mission Operations. “Less than two years ago, this integrated team put in place a very challenging plan to launch five EELV/NRO missions in less than seven months. The combined NRO Office of Space Launch, U.S. Air Force Launch & Range and ULA teams have executed this plan flawlessly, culminating in today’s successful launch aboard our 25th Atlas V rocket. With each of these incredibly important launches, we are reminded of the role we play in offering enhanced effectiveness and safety to the men and women protecting our country. Congratulations to the ULA team and our government, mission, and supplier partners for making these five successful NRO missions possible.”
This mission was launched by an Atlas V 411 configuration launch vehicle, which uses a single common core booster powered by the RD-180 engine and one solid rocket motor. This was the fourth launch of 2011 for ULA, including two for the NRO and one for the United States Air Force.
ULA's next launch is the Atlas V SBIRS GEO-1 mission currently scheduled for May 6 from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla.
ULA program management, engineering, test and mission support functions are headquartered in Denver, Colo. Manufacturing, assembly and integration operations are located at Decatur, Ala., Harlingen, Tex. and San Diego, Calif. Launch operations are located at Cape Canaveral AFS, Fla., and Vandenberg Air Force Base, Calif.
For more information on the ULA joint venture, visit the ULA website at www.ulalaunch.com, or call the ULA Launch Hotline at 1-877-ULA-4321 (852-4321).

I was lucky enough to be invited out with the media for this launch, and the pneumonia I'll probably catch next week from standing out in the freezing cold for an hour waiting for this thing? SO worth it. One of the most beautiful launches I've seen. I actually forgot how bright these Atlases are, so my streak shot got washed out big time unfortunately, but oh well...live and learn. I've already got settings in mind for the next time. Anyway, here's my shots:

A "soundtrack" to this launch? Gotta be "Heaven's On Fire" by KISS

burn with me, Heaven's on fire
Paint the sky with desire,
angel fly, Heaven's on fire"

Here is what it looked like from the South Base gate:

Interesting. The payload may turn out to be an NOSS pair, instead of a HEO ELINT sat as some guessed before...

http://www.satobs.org/seesat/Apr-2011/0202.html (http://www.satobs.org/seesat/Apr-2011/0202.html)
That is a very interesting development. Observations have confirmed two NOSS satellites:
http://satobs.org/seesat/Apr-2011/0202.html
NOSS pairs were put into orbit using a two burn profile for Centaur with a rather long coast phase . The second burn failed during the NROL-30 mission. Now it seems, they have added a booster so that the mission can be conducted with a single burn of Centaur to avoid a second burn after a longer coast phase.
I wonder, if this change has cosequences for other future LEO missions like the NROL-41 type (FIA-Radar ?) satellites.
-
I think FIA used a direct ascent anyway, so it probably wouldn't be affected.
This also means that the two upcoming 401 launches are probably SDS.

The second USA 229 payload has now been cataloged by the US as 37391,
and named "USA 229 DEB" (i.e. "debris"- hello JSPOCchio, did I just see your nose get longer by another couple of inches??)
It is being tracked by hobbyists in a 1017 x 1205 km x 63.4 deg orbit.
