Live thread for the Atlas V NROL-33 launch.
Article:
http://www.nasaspaceflight.com/2014/05/ula-atlas-v-nrol-33-launch/
Does anyone know the tail number (AV-0xx) of the Atlas/Centaur vehicle used in this NRO launch?
Kind regards,

I don't think Phoenix carried a sword.
but it does appear she is right above North America providing some sort of protection.
Someone with better knowledge of mythology than me will need to tell us which war goddess this is.

The NROL-33 launch date is no longer May 7th as the ULA press release from NROL-67 launch states the next ULA launch is a Delta IV on May 15th

Found this patch on eBay:

http://www.webcitation.org/6OlSeSzVI
I'm not 100% sure that AV-046 is NROL-33, but this is the sort of launch patch I'd expect for an NRO mission. "Defendi nostrae opes" translates as "to defend our resources". Note the eight stars on the sides of the patch - these have appeared in the same pattern on several past NRO patches all of which were associated with Quasar communications satellites.
It is interesting to see Europe prominently featured on the patch. It could suggest a geostationary satellite positioned over this part of the world, however if this were a Quasar I would expect it to go to a Molniya orbit since both of the GEO satellites were recently replaced. Unless they are increasing the number of geostationary satellites in the constellation.

It wouldn't surprise me if they weren't increasing the number, the communication requirements must be huge considering the amount of data that is probably generated by these systems. The bottleneck in data networks is usually communications capacity & I don't see why this should be any different.

It is. Launch vehicle patches barely keep up with the launch rhythm. The next Delta IV is not out yet.
-
Any word yet on when this launch might happen I would imagine scheduling on the Cape between Orbcomm and NROL-33 will be settled soon if both are shooting for May launch.

You know spaceflightnow reports a date of May 22 so I will go with that for now sure Orbcomm will be within a week after that

Atlas V to Launch NROL-33
Rocket/Payload: An Atlas V 401 will launch the NROL-33 mission for the National Reconnaissance Office (NRO).
Date/Site/Launch Time: Thursday, May 22, from Space Launch Complex (SLC) 41 at Cape Canaveral Air Force Station, Fla.
Launch Notes: NROL-33 will be the 46th Atlas V mission since the vehicle’s inaugural launch in 2002. It will be the sixth of 15 planned missions ULA is slated to launch in 2014, and ULA’s 83rd since the company formed in 2006.
Mission Description: The mission will be launched for the National Reconnaissance Office in support of national defense.

I don't think it can get any clearer than this. This is when we find out whether there was anything but hot air in the Russian government's statements over the past week.

How would this effect a payload like WorldView 3, launching on an Atlas, yes it's a commercial payload but it has both military & commercial customers?

No effect because the ban does not include NRO or USAF payloads. "Military applications" mean weapons
-
I think at issue here is Russia's ability to confirm the precise nature of every payload under the fairing. I'm not suggesting a relatively benign NRO payload would be used as a cover for something darker, but similar things have happened in the past.
To use just one example as an attempt to explore the issues, what if an Atlas V payload included a powerful transmitter capable of "jamming" the communications signals of opponents? What if the transmitter were strong enough to permanently damage the comm equipment of the opponent? Would that payload -- which might sit hidden for years on an otherwise strictly reconnaissance platform -- be a weapon?

This think-tank that specializes in Russia and ex-USSR is being hammered up and down by hackers but has an article about what the Russians are saying, doing and claiming about this whole space mess that covers more space issues than we have seen addressed in NSF:
US Restrictions Hurt Russian Space Defense and Commercial Projects
Publication: Eurasia Daily Monitor Volume: 11 Issue: 91, May 15, 2014 By: Pavel Felgenhauer
http://www.jamestown.org/single/?tx_ttnews%5Btt_news%5D=42363&tx_ttnews%5BbackPid%5D=7&cHash=aa4e9fe87ccb03e5d58e0cb517edb4cb#.U3lC83Wx3UZ (http://www.jamestown.org/single/?tx_ttnews%5Btt_news%5D=42363&tx_ttnews%5BbackPid%5D=7&cHash=aa4e9fe87ccb03e5d58e0cb517edb4cb#.U3lC83Wx3UZ)
Before the Ukrainian crisis, during the heyday of President’s Barack Obama’s “reset” charm offensive, Washington was apparently turning a blind eye to aggressive Russian procurement of high-tech, double-use equipment and technologies. Today a US move to deny high-tech export licenses threatens to set back the entire Russian military modernization project, which is based primarily on using space-connected technologies to develop new precision weapons, intelligence-gathering, communications, and command and control capabilities. In response Rogozin went ballistic, threatening to terminate US-Russian space cooperation programs: to stop selling RD-180 and NK-33 rocket engines “if they are used to launch US military satellites,” to close down GPS correction (Global Navigation Satellite System—GNSS) stations on Russian soil, and sink prematurely in the ocean the International Space Station (ISS) by 2020 (http://www.rg.ru/2014/05/13/bumerang-site.htm).
Russia has previously tentatively agreed to continue to jointly run the ISS until 2024, but now Rogozin insists this is senseless and the space station must be terminated by 2020. He suggested that the money saved be diverted to more ambitious programs, like creating a permanent Russian base on the Moon to mine and claim it as Russian territory by 2030, before other nations form a substantial presence there (http://izvestia.ru/news/570482)
This week in Sochi, President Vladimir Putin announced: “We must ensure that everything our defense industry needs and uses is produced on our territory and we do not depend on anyone” (http://www.kremlin.ru/news/21021). Russian experts consider Putin’s call for complete scientific and technological self-sufficiency to be an impossible task (http://top.rbc.ru/politics/14/05/2014/923813.shtml). Russia’s Trade and Industry Minister Denis Manturov told journalists that he was surprised by calls to undermine the work of GPS-connected equipment in Russia. He did not see any sense in such obstruction and wondered if “Rogozin was just promoting his personal opinion” (http://www.interfax.ru/print.asp?sec=1448&id=376041). Manturov was immediately rebuked: A government spokesperson confirmed all announced anti-American moves were officially approved, while Rogozin demanded Manturov “end being part of the fifth column” (http://www.interfax.ru/russia/376039). Rogozin’s anti-American sanctions may hinder Russia more than the US, but they follow Putin’s general line to isolate Russia from the West as much as possible.
Lots more meat in the article including discussion of the RD-180s and the Geo-IK-2 issue that upset Rogozin and set this whole escalation off.

This NOTAM for the de-orbiting of the Centaur is at about 10 hours (!) after the opening of the launch window - near Kwajalein in the middle of the Pacific of all places; and the shape of the area seems to hint at this being a low-inclination launch. Hmm....... ::)
-
Does that imply the Centuar will be doing an apogee de-orbit burn for an HEO GTO type orbit.
So a restart 5 hours into the launch? Impressive.

Yes, apparently during the launch of NROL-38 a similar procedure was done (http://forum.nasaspaceflight.com/index.php?topic=28559.msg918004#msg918004) in the same area of the Pacific Ocean (except that the de-orbit area stretches northwest-southeast that time, while this time it is from southwest-northeast).

With this satellite looking more like heading to geosynchronous, I wonder if the Molniya orbit SDS satellites are going to be replaced by a newer generation of satellites? Come to think about it, NROL-35 is launching this December from Vandenberg on a heavier rocket (Atlas V 531) - maybe that will replace one of the older Molniya orbit satellites? It's not like that the Molniya orbit satellites are THAT old (USA-179 was launched in August 2004 on the last Atlas II and USA-198 was launched on Atlas V in December 2007).....

It seems like going all-GEO is a natural evolution of relay.
The original Molniya SDS constellation was intended to relay photo reconnaissance data directly from a reconsat to a ground station in the U.S. in only one bounce--up to the SDS, down to the ground. However, there were discussions (I think they were mid-late 1970s) of going to a system that used multiple satellites in GEO. Then you can get to the ground in probably two bounces, or maybe three at most. A bit more complicated in terms of the overall constellation, but it probably solves a lot of other issues. For instance, the Molniya satellites fly through the Van Allen Belts. Not cool. Also, it's probably a bit of a pain figuring out where to point your antennas all the time. With a GEO constellation that should be simpler because the GEO satellites are not always moving their location, they're fixed.
-
There's also the background to whats gone on in the GEO sat market since the first SDS birds launched given a wider commercial base to leverage.
The original TDRS fleet were, AIUI pretty much custom TRW vehicles; the current block 3 Boeing TDRS units are built on the common 601/701 bus, with a unique payload, much like any other Comsat.

Not to nit, but the original SDS satellites in Molniya orbits are believed to be based on commercial GEO platforms. Specifically the Hughes HS-350 bus. Siruis adapted Space Systems Loral LS-1300 bus for Tundra orbits (similar to Molniya).
GEO platforms can and have been leveraged for Molniya orbit satellites. So that must not be it.
-
Nit away - missed the link to the Hughes bus.
The other point I think I was trying to make is that there is more synergies with the commercial side which would drive confidence and cost savings.

Yeah, I concluded that Intelsat IV, SDS, and Jumpseat were all probably closely related. They were derivatives (or at least descendents) of Tacsat.

United Launch Alliance Successfully Launches Four Missions in Just Seven Weeks
A United Launch Alliance (ULA) Atlas V rocket carrying a payload for the National Reconnaissance Office (NRO) lifted off from Space Launch Complex-41 on May 22 at 9:09 a.m. EDT. Designated NROL-33, the mission is in support of national defense.
“Congratulations to all of our mission partners on today’s successful launch of the NROL-33 mission! The ULA team is honored to deliver another critical national security asset to orbit together with the NRO Office of Space Launch and the Air Force,” said Jim Sponnick, ULA vice president, Atlas and Delta Programs. “Today’s launch occurred six days after last week’s GPS IIF-6 launch – the second time this year that this team has launched back-to-back missions within a week. Successfully launching at this tempo is a testament to the team’s focus on mission success, one-launch-at-a-time, and continuous improvement of our launch processes.”
This mission was launched aboard an Atlas V Evolved Expendable Launch Vehicle (EELV) 401 configuration vehicle, which includes a 4-meter-diameter payload fairing. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine, and the Centaur upper stage was powered by a single Aerojet Rocketdyne RL10A engine.
ULA's next launch is the Delta II OCO-2 mission for NASA, scheduled for July 1 from Space Launch Complex-2 at Vandenberg Air Force Base, Calif.
The EELV program was established by the United States Air Force to provide assured access to space for Department of Defense and other government payloads. The commercially developed EELV program supports the full range of government mission requirements, while delivering on schedule and providing significant cost savings over the heritage launch systems.
With more than a century of combined heritage, United Launch Alliance is the nation’s most experienced and reliable launch service provider. ULA has successfully delivered more than 80 satellites to orbit that provide critical capabilities for troops in the field, aid meteorologists in tracking severe weather, enable personal device-based GPS navigation and unlock the mysteries of our solar system. Reliable launch, real-world benefits.

Interesting nugget from AL STERN Satellite Beach FL, an amateur radio enthusiast who monitors Florida air comms. Any ideas out there what sensors the aircraft was carrying?
"WB-57F "NASA 927" (63-13295;ex 53-3918) just landed at Patrick AFB after participating in the launch of the Atlas V rocket this morning. During the launch I heard comms from NASA 927 with CCAFS Tower on 118.625, discussing F-Stop adjustments to its cameras."

What is the NROL-33 mission nickname (like Gryphon, Drake, etc)?
Perhaps this has been posted somewhere, but I couldn't find it.

A leading amateur observer found what he believes is USA-252 still in it's transfer orbit
1) Early on in the run an unknown [99418/14644A] was seen and tracked until I saw the second unknown. The object is in a geostationary transfer orbit, and the measurements provide a good constraint on all parameters, with a mean motion of 2.24 revs/day:
1 99418U 14644A 14144.03015972 .00000000 00000-0 00000-0 0 04
2 99418 20.6956 263.7634 7074111 178.0121 96.0401 2.24037956 01
# 20140524.02-20140524.04, 79 measurements, 0.003 deg rms
The orbit has the perigee at the descending node, and the plane passes over Florida at the time of the NROL-33 launch from last Thursday. I am confident that this object is NROL-33/USA 252 [39751/14027A], presently still in its transfer orbit.

I only just noticed this: why is the upper SRB attachment area now white? Looks like a relatively recent change.

The change seems to have appeared at the pads during 2012, around the same time that the "AV-XXX" numbers disappeared. This may roughly coincide with the production move to Decatur.
As for why, I can only guess. It might provide a bit of a thermal barrier. It might be for visibility for tracking cameras, to help confirm clean separations. It might improve visibility during assembly, when the solids are attached on the pad. It might be a different corrosion coating.
