Title: LIVE: Atlas V - MUOS - February 24, 2012
Post by: Chris Bergin on 04/01/2008 09:31 pm
U.S. Air Force Awards United Launch Alliance MUOS Satellite Launch
Denver, Colo., (April  1, 2007) - The U.S. Air Force Space and Missile Systems Center awarded United Launch Alliance a contract modification to perform the launch services for the U.S. Navy's first Mobile User Objective System (MUOS) satellite aboard an Atlas V Evolved Expendable Launch Vehicle. The anticipated launch date is the first quarter of 2010 from Space Launch Complex 41 at Cape Canaveral Air Force Station, Fla.
MUOS is a next-generation narrowband tactical satellite communications system designed to provide significantly improved and assured communications for U.S. forces on the move.  The system will deliver simultaneous voice, video and data, as well as improve service to legacy users of the Navy's Ultra High Frequency Follow-On (UHF F/O) system currently on-orbit.
"United Launch Alliance is proud to continue our long partnership with the Navy, which includes the successful launch of four UHF F/O satellites on Atlas within the last decade," said Jim Sponnick, ULA vice president of Atlas programs.  "Cost-effective assured access to space is our continuing commitment to the U.S. government, and we are looking forward to working with the Air Force, the Navy and Lockheed Martin Space Systems to launch this latest technology for the mobile war fighter."
Lockheed Martin Space Systems, Sunnyvale, Calif., is the prime contractor and systems integrator for the MUOS program.  The Navy's Program Executive Office for Space Systems, Chantilly, Va., and its Communications Satellite Program Office, San Diego, Calif., are responsible for the MUOS program. 
ULA program management, engineering, test and mission support functions are headquartered in Denver, Colo. and are supported by transition employees in Huntington Beach, Calif. Manufacturing, assembly and integration operations are located at Decatur, Ala., Harlingen, Texas, San Diego, Calif., and Denver, Colo.  Launch operations are located at Cape Canaveral Air Force Station, Fla., and Vandenberg Air Force Base, Calif.


PENTAGON ANNOUNCEMENT:
Lockheed Martin Space Systems Co. of Littleton, Colo., is being awarded a modified firm fixed price contract for $124,100,000. This modification is issued to purchase launch services from Lockheed Martin Co. under the Evolved Expendable Launch Vehicle Program and Atlas medium-plus rocket (Atlas 5510 to launch the Mobile Users Objective System (MUOS)-1 Satellite. At this time $124,100,000 has been obligated. El Segundo, Calif., is the contracting activity (FA8816-06-C-0004, Modification Number P00002).

Those in the know: is this a typical Air Force launch (government) or a typical Navy launch (commercial)?  The press releases seem to be vaguely in conflict.  One says ULA, the other LMSSC.

This contract does not appear to be part of any EELV "buy", but procured commercially through LM Commercial Launch Services, which is probably part of SSC.  It's possible that $124.1 million is full price for a 551, but that seems really low.

MUOS was one of the satellites planned for the EELV Buy 3 to be conducted by the Air Force.  Unlike the UHF Follow On satellites, MUOS uses the same contracts as used by the Air Force and NRO.  And while it is ULA that will produce the booster and do mission integration, launch ops, etc, the EELV contracts are still legally between USAF and Lockheed Martin  (and Boeing).  ULA doesn't have the systems in place, yet, for the old contracts to be transferred (novated) to them.  Once the contracts are transferred, then it will be the AF contracting with ULA.  Tough to capture in a press release these specific details -- if the public affairs people write "Lockheed Martin", then people ask why it isn't "ULA".  And vice versa.

Does this really require an 551? How heavy is this satellite? UHF sats (HS-601) worked just fine with Atlas 2.

S/C mass = 13,000 lb. It's the most massive A2100 built by LM to date. UFOs massed no more than 3500 lb.


13,000 lb. Didn't know they are this heavy. Much more capable I assume so you need less. Thanks.

Wow, $124.1m for a Atlas 551.  This sounds like a great price.  Based on performance numbers quoted on this site before this results in $3,043/lb to LEO.  Or if one could get a 552 for the same price $2,674/lb.  Sounds very competitive.

Remember the government pays many hundred million each year just for the capability (fixed), independent of launches or not. So these are variable costs at best.

I thought the 2 engine centaur requires a large amount of engineering work since the current 1 engine uses electrical not hydraulic actuators that the old two engine centaur used.

I assume the smallest Delta IV this can fly on is a Heavy. So how much is being saved flying it on an Atlas 551?

Still amazed, an Atlas 551 that is not being used for a BEO mission and Atlas shrugged ...

Off topic, but are any other Atlas 551 missions on the books?

That's what I have, with the following count as of now.

Vehicle      Launch Total(Failures)
===================================
Atlas Centaur     148(15)
Atlas V            28(1)
Titan IIIE          7(1)
Titan 401A          9(1)
Titan 401B          7(1)
-----------------------------------
Total             199(19)
===================================

12 of the 19 failures involved Centaur stages in some way.  These included propulsion, structural, control, and guidance/control system failures.  Of the 12 Centaur failures, 9 were on Atlas Centaur and one each were on Atlas V, Titan IIIE, and Titan 401B - the latter was the infamous bad software load in 1999.  The 12 Centaur failures were distributed during the following decades.

1960s    5
1970s    2
1980s    1
1990s    3
2000s    1

   It is mildly amusing to note that, although the AV401 is much the most common config, we're in the middle of a rare set of heavyweight or high energy launches: 551-541-551-531.

Considering the hit the Delta IV schedule took pulsing through all the Heavies the last few years, I hope we don't see a similar set of Atlas delays from these payloads of unusual size.

From the mission book, which is now available at:

http://www.ulalaunch.com/site/docs/missionbooklets/AV/av_muos1_mob.pdf

the attached image shows the ascent ground trace.  The yellow X marked "1" is Centaur MECO-1.  At that point it has reached its parking orbit.  Note the red trace becomes green somewhat before that point.  The legend says red is "mandatory" telemetry coverage and green is only "required" telemetry coverage.  I translate this to mean the range requires coverage for the red section so they can initiate abort destruct if they deem it necessary.  I'm thinking the red-to-green transition is thus the location of the Africa gate, i.e. that's the location of the vehicle when the instantaneous impact point crosses into Africa.

Any comments on that analysis?

Not quite.  The mandatory vs required is for telemetry for engineering purposes and not range safety.   Notice the trace goes red at the second burn.  The range is not involved there.  As for the green/red transitions compared to the "X", that might just be graphical inaccuracies.

Also, there is no room to show red for the 3rd burn

I considered that.  Had it been range safety related I would have expected it to be exactly correct.  As it is, you're right that something like artistic license might also explain it.

      Err, could you expand on that? There have been only two Heavies in the last three years. How could that have driven the Medium's launch rate, and even if it did, why would such be applicable to the single-core Atlas?

Yes, my understanding is that the S-V was essentially a Centaur (although this in part comes from Astronautix, which considers anything powered by one or more RL10s (with the possible exception of the S-IV) to be a Centaur, so it could be wrong). I would be interested to find out more about the S-V.

There was no mockup of the S-V flown.  The Saturn I used Jupiter nose ones.
The S-V was to be a stock Centaur.

nose cones?

The attached drawings of SA-1, the first Saturn I (a Block 1 version), shows the configuration.  No upper stages were flown on the first four suborbital tests.  Water filled tanks were used to simulate the then-planned S-IV and S-V upper stages.  The S-IV dummies were built by what is now MSFC using what were likely Jupiter tanks surrounded by a dummy structure, but the S-V tanks may have come from Convair.  The plan, at the time, was for S-V to be very similar, if not exactly like, a Centaur stage.  In the end, the S-V stage was cancelled and never tested on Saturn.

And yes, the first few Saturns flew with Jupiter nose cones at their tips.  Note that an extension-adapter had to be added to fit the Jupiter nose cones to the 10 foot diameter S-V dummy.

The first Mobile User Objective System (MUOS) satellite is scheduled to launch aboard an Atlas V rocket from Cape Canaveral Thursday, February 16. 

Congratulations PMW-146!!!!!

The launch window is 1746 to 1830 EST (1446 to 1530 PST). 

You can watch the launch LIVE steaming on line. A Link available on the SPAWAR web page.

http://www.public.navy.mil/spawar/Press/Pages/MUOS.aspx

On the San Diego Old Town campus, the launch will be projected in Cantrell C. If you have a chance, please stop by Cantrell C and join our PMW-146 teammates as they observe the launch.

=============================
Navy Launches Next Generation Communications Satellite Feb. 16, 2012

All U.S. military forces rely upon Navy satellites for narrowband communications. The Mobile User Objective System (MUOS) is the Defense Department’s next-generation narrowband satellite communications system. It will support users worldwide by providing increased communications capabilities to smaller terminals while still supporting legacy system radios and terminals. MUOS is designed to support users that require mobility, high data rates and improved operational availability. The system will provide greater than 10 times the system capacity compared to the current constellation.

- The first MUOS satellite is scheduled for launch Feb. 16 from Cape Canaveral Air Force Station, Fla.   

- The Air Force oversees most DoD space systems, but the Navy is responsible for DoD’s narrowband satellite communications.

- This spectrum is the military’s communications workhorse because it is the only radio frequency that can penetrate jungle foliage, inclement weather, high sea states and urban environments.

- More than 60 percent of military satellite communication users are supported via the narrowband spectrum.

- Approximately 67,000 narrowband terminals are currently in military use on more than 50 terminal configurations.

- The MUOS constellation will consist of four satellites plus one on-orbit spare and a terrestrial network connecting four ground stations around the world.

- MUOS will provide users 10 times more communications capability compared to today’s system.

- By leveraging 3G mobile communications technology, it will provide simultaneous voice, video and data capability.

- Born from the need for stable, 24/7 ship-to-shore communication that could be successful regardless of environmental and geographical conditions, the Navy is assigned to provide crucial narrowband satellite communication.

- Beyond providing communications for all branches of the U.S. military and many of its allies, Navy provided space-based narrowband capability also ensures reliable worldwide coverage for national emergency assistance, disaster response and humanitarian relief.

Aerospace is evaluating the 6th balloon steering set against the 9th balloon low level data.

Based on when the Go will be available, the count will probably be picked up and then wait for the Go from winds.  Hold/scrub will be called at T-1:00 if a Go is not received by then.

It would need the equivalent of a 6th SRM for that.  It doesn't have the excess margin both in performance and structural capability.

I believe the issue is not one of "aim" while dealing with the winds but of a trajectory that minimizes angle of attack loads and other stresses on the vehicle. A 200 foot long tube can experience some dramatically different wind at the tip vs. at the tail, particularly when pushing through a dramatic shear layer.

Goes to show. This was only a 10 percent weather violation today!

Upper level winds is not included in the weather criteria.  Upper level winds is a vehicle capability constraint.

Thanks Jim, I didn't know that!

They better be sure that they knew what they were doing because:

A.  If they are right, it reflects bad on ULA
B.  If they are wrong, it reflects bad on them and cost the USAF some bucks

This only applies if the call was due to an LV issue, spacecraft is another thing.  Then it is between the spacecraft contractor and Aerospace

Cape Canaveral Air Force Station, Fla. (Feb. 16, 2012) – The launch of an Atlas V carrying the United States Navy’s Mobile User Objective System-1 (MUOS-1) payload was scrubbed today due to weather conditions associated with upper level winds.

The Atlas V vehicle and MUOS are safe and secure at this time. The launch is rescheduled for Friday, Feb. 17 from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla. The opening of the launch window is 5:42 p.m. EST and extends until 6:26 p.m. The forecast for Feb. 17 shows a 40 percent chance of favorable weather conditions for the launch tomorrow.

As AC-67 taught us, if the weather isn't within the flight rules, a scrub is preferable to risking a failure.

There "isn't" one.  The relationship is between Aerospace and USAF.
Aerospace is the USAF's GSE&I contractor for space systems.

The Department of Defense has identified five core competencies for the Aerospace FFRDC*: launch certification, system-of-systems engineering, systems development and acquisition, process implementation, and technology application.

*Federally funded research and development center

So everyone's on the same page. We'll start Friday's updates for this launch on this thread, as a continuation.

In the meantime, review William Graham's extensive preview article, which is now into Rev 2 with an additional 1,200 words on Centaur!:

Well, it certainly was right down to the wire, and as others have mentioned, you want to fly safe.

Yeah, feel bad to those who went to see it in person, and I too hope John Glenn can stay around until it launches.

Besides, weekend launches often allow greater opportunity for a larger viewing audience  :)

Still confused. So Aerospace provides ground support and mission oversight for USAF flights as a contractor of the USAF?

Is that why they are monitoring the balloons and calling the red/green on winds aloft, since that is part of the services they provide?

Not clear to me that Aerospace Corporation called the hold.   They are on the comm nets, but historically they do not have a speaking roll in a countdown on the launch vehicle side. (Question is whether hold was for LV, SV, or range.) They advise the Air Force Program Manager and the Air Force Mission Director regarding launch vehicle flight worthiness (per Air Force Space Command Instruction) - but it is the AF folks who should call the Hold, not Aerospace, if the Government team saw something that ULA did not.

Great forum, just found it.  I was watching tonight with my family from SR-528.  My 7yo was extremely excited, he loves anything space and tech and his class just visited the McAuliffe-Shepard Discovery Center in Concord, NH a couple of months back.  It was disappointing but these things happen.  With an hour drive each way from Disney and only a 40% chance of weather cooperating, I doubt my wife (could care less about spaceflight) will be willing to cut our day short from Disney to drive back out, but I'll keep an eye on this thread and hope it all comes together and we can be back for what for us is likely to be a once in a lifetime opportunity.

It's my understanding there is no longer any way to observe the launch from Cape Canaveral itself, correct?  It sure would be great to find a location where you can actually see the launch pad, but I imagine for safety and security reasons that's probably not possible.  The website mentioned something about buying tickets for a launch but when I called and spoke to someone there I was told you couldn't buy tickets or get anywhere in sight.  Confusing!!

There are no tickets because it is not a NASA sponsored launch.  The USAF doesn't let the general public on CCAFS for its launches.

No that is not correct, they were indeed selling tickets for this launch to view from the Saturn V Center and have done that for several recent launches since the shuttle ended (and sold tickets for the causeway for GRAIL).

Tickets were sold (and may be available for Friday or later) to view from the Saturn V Center, at just five miles away one of the two best places you could view from. The other option was to go to Playalinda Beach, also about five miles. Many people were there to view it, while others are reporting they were turned away after 5pm and police were staioned in the parking lot post-launch trying to clear the area.

So, you could get closer than Port Canaveral for this launch although I would label Playalinda risky for the next attempt. Get there early if you try it.

In regards to the AC-67 failure, the issue was with the formation of lightning.  The launch constraints state the following: "The flight path of the vehicle should not be through middle-level cloud layers 6,000 feet or greater in depth, when the freezing level is in the clouds." At Baikonur, the freezing level is kind of a moot point during the cold season since it's below 0 Celsius at any altitude... basically it's difficult to compare the weather on the Eastern Range with Kazakhstan because they are very different, but it does make for some interesting "blast-off in a blizzard" pictures!  :)

where will I get a better launch experience - Kennedy visitor center parking lot (close but no direct line of sight ) or port canaveral (further away but direct line of sight)?

Any help would be much appreciated - thanks and let's hope we get a launch!

Sorry Chris - time was of the essence and I was not sure where to look quickly - apologize. I did find the launchphotography site and others with similar questions could look here:

Didn't we have a viewing thread for Cape launches somewhere? We'll need to keep this only on launch updates, so if someone can post we'll redirect people asking about viewing.

Cumulus clouds, disturbed weather, thick clouds.

(They're the same set of nine lightning LCCs probably for all the LVs that fly out of KSC/CCAFS.)

Cumulus clouds, disturbed weather, thick clouds.
These were the three primary concerns for today's launch attempt (#3, #7, #8 on the weather board) in the 45th Weather Squadron forecast issued at 9 am local.

Looks/sounds like the ULA webcast is going 'bars and tones' again...

Ah, I thought you had already seen that and was looking for more ;D - the above from Ben is certainly a good one!

However, note to all, we really do need to set up a sticky thread for the Cape launches, led by Ben's link and build from there. Wasn't/isn't a problem posting in here, but I was just trying to think of a faster way for people to discuss viewing spots, allowing this one to focus on updates.

What are the limits of the upper level wind contraints?

The rocket has to fly through wind shears (dv/dh) without detrimental bending due to excessive side force or aerodynamic tumbling due to excessive angle of attack.

Still expecting the thick cloud rule to go green in the next few minutes and only for about 10 minutes or so (Don Spencer was saying about 2253-2303Z / 1753-1803L).  Not exact timing, but it does sound like they're trying to 'thread the needle' through a hole in the weather.

Cape Canaveral Air Force Station, Fla. (Feb. 17, 2012) – The launch of an Atlas V carrying the United States Navy’s Mobile User Objective System-1 (MUOS-1) payload was scrubbed today due to weather conditions associated with upper level winds and flight rules associated with thick clouds. Due to lack of range availability and also the forecast weather conditions for the next several days, the Atlas V vehicle and MUOS will return to the Vertical Integration Facility and will roll back out to the launch pad prior to launch. The launch is rescheduled for no earlier than Wednesday, Feb. 22 from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla.

I completely forgot about this launch, and just now checked the thread.  I'm glad to see I didn't miss anything, but course it's unfortunate for those people who actually traveled to see the launch.

Chris:
I don't know if there is a correct place to make suggestions, but one thing I've thought about for a while is how about listing the date of the next scheduled launch on the front page of the forum, with a link to the proper thread?  It wouldn't have to take up much space; just the date and maybe launch vehicle type.

Rickl,

I also would like that too.  So I created a formal request to Chris on the site's Development and Q&A thread for you and myself.

We had such a thing on the forum. About two people a week clicked it, and most poeple simply kept on posting external resources - as has already happened on this thread.

It's not possible to add it to the news site, so a non-starter for the development section.

Note: We already have schedule manifests for the vehicles on the forum, such as on the relevant vehicle sections.

Here's ULA going official with the 24th:

United Launch Alliance Set to Launch U.S. Navy Payload Feb. 24

 

Cape Canaveral Air Force Station, Fla. (Feb. 21, 2012) - The launch of an Atlas V carrying the United States Navy's Mobile User Objective System-1 (MUOS-1) payload from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla., is set for Friday, Feb. 24, following two weather scrubs late last week. The opening of the 44-minute window opens at 5:15 p.m. EST. The Atlas V vehicle will roll back to the launch pad Thursday, Feb. 23 in preparation for launch. The current forecast shows a 40 percent chance of favorable weather conditions for launch. MUOS is a next-generation narrowband tactical satellite communications system designed to significantly improve ground communications for U.S. forces on the move and will provide military users 10 times more communications capability over existing systems.

Weather briefing: plenty of dry air. Have been some brush fires west of I-95 in the last few days, if one started in the wrong place the plume could pass over the pad.  Wind constraint is 31 or 32 knots depending on direction.  Peak gust today has been 27 knots.  Steady state around 20 knots.  POV for 24-hr scrub is 20%.

Yes, it is the medium version of the 5m fairing. All other 5m Atlases except for the NROL-41 launch used the short 5m fairing.

It's the medium length five metre fairing. Most of the 5x1 launches so far have used the short one. I believe the only other launch to use the medium was NROL-41, on a 501 from Vandenberg

The pictures from the camera on Centaur looking at the RL-10 were very impressive.  Was this a new camera or have they just not shown that camera footage before?

I saw the TVS carry out the post-sep pitch manoeuvre very clearly and the turbo-pump exhaust was spluttering very dramatically.

As Ben noted, that's the turbopump exhaust port/plumbing.

What's the mini nozzle to the right of the main nozzle for? Roll control?

Post by: jongoff on 02/24/2012 09:33 pm
Um...if you're talking about Centaur, the RL-10 does not have an exhaust port. It's an expander cycle engine--the turbine is driven by the warmed fuel from the cooling jacket, and all of it gets dumped into the combustion chamber.  The "turbopump exhaust port" on an expander-cycle engine is also known as the main injector...

The smaller nozzles are either the settling thrusters or the RCS thrusters, both of which are little hydrazine jobbies. I'm guessing you're seeing the settling thrusters.  The RCS ones come in little clusters, with some of the nozzles bent in various angles.

I'm not sure if I have any public references I could send you to, but the Centaur stage has 4 small settling thrusters (which run in either steady state or pulsed mode), and I think 12 hydrazine thrusters, mounted in clusters of 2-4 engines. The settling thrusters are used for making sure the propellant position inside the tanks is maintained properly during coast phases, and the other thrusters are used to control pitch, yaw, and roll.

Actually, here's a reference for the RCS jet clusters:

According to the data on the CGI screen, orbit at MECO2 was 18600 x 104 nautical miles.  Is that what they call 'Geostationary Transfer Orbit'?

It is close, but a bit short of the standard GTO from the Cape, which would usually have a bit higher apogee.  On this mission, though, Centaur will perform a third burn near apogee.  They're aiming for a final 19,323 nmi x 1,870 nmi x 19 deg orbit.  I actually expected a 19,300 nmi apogee after the second burn, but the orbital mechanics may be more complex on this mission. 

EDIT:  On review I see that AV-030 nailed its planned mark at the end of Burn 2.  The plan was for 18,600 x 104 nmi x 26 deg.

NEW MILITARY COMMUNICATIONS SATELLITE BUILT BY LOCKHEED MARTIN LAUNCHED SUCCESSFULLY

 

 

CAPE CANAVERAL AIR FORCE STATION, Fla., February 24, 2012 – The first Mobile User Objective System (MUOS) satellite, built by Lockheed Martin [NYSE: LMT] for the U.S. Navy, was successfully launched today from Cape Canaveral Air Force Station, Fla., aboard a United Launch Alliance Atlas V rocket.

 

The MUOS constellation will replace the legacy Ultra High Frequency Follow-On (UFO) system and provide significantly improved assured communications, including simultaneous voice, video and data, for mobile warfighters.

 

“MUOS is a revolutionary new satellite system that will provide unprecedented new communications capabilities for the armed forces,” said Kevin Bilger, Lockheed Martin vice president and general manager of Global Communications Systems.  “We look forward to executing a smooth and efficient on-orbit checkout, paving the way for operational use.”

 

MUOS satellites feature a wideband code division multiple access payload that incorporates advanced technology to provide a 16-fold increase in transmission throughput over the current UFO satellite system .  A single MUOS satellite will provide four times the capacity of the entire legacy UFO constellation of 10 satellites.  The satellites also include a hosted legacy UHF payload that will be fully compatible with the current UFO system and legacy terminals.

 

The first MUOS satellite and associated ground system will provide initial on-orbit capability this year with the four-satellite global constellation achieving full operational capability in 2015, extending UHF narrowband communications availability well past 2025.

Lockheed Martin Space Systems, Sunnyvale, Calif., is the MUOS prime contractor and system integrator. The Navy's Program Executive Office for Space Systems, Chantilly, Va., and its Communications Satellite Program Office, San Diego, Calif., are responsible for the MUOS program.

Headquartered in Bethesda, Md., Lockheed Martin is a global security company that employs about 123,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation's net sales for 2011 were $46.5 billion.

Actually, here are related questions: Do all the cameras transmit throughout the flight or are they turned on or off by the ground controllers.  If they are on throughout, are they 'live', i.e. transmitting their images?

If the ansewr is 'yes', then ULA probably have recordings of the entire flight from the POV of CCB down, CCB up, RL-10 engine bay and Centaur up (facing the payload like the one on the MSL launch).  Maybe they could do an ascent video like NASA did of all the different cameras on the RSRMs during shuttle flights?  :)

Only the Shuttle had uplink capability.  No American rocket currently receives ground commands.  Well, there is one command, but that's the one you don't want to send.  The flight computers have enough memory and speed that they can do everything necessary including FDIR if there is a way to recover.

Yeah, definitely my mistake.  When I saw his question, I didn't realize that Ben was referring to the video. I thought he was describing one of the lateral settling thrusters. But when I saw the video, I saw the vent line he was talking about--though wasn't sure what was being vented.  Thanks for the info! And apologies earlier to Ben and the others for playing the know-it-all when I apparently didn't have all my facts in-hand--I was right on what it wasn't, but not on what it was...

the Atlas V is a very reliable rocket that has never failed a launch so far but the Atlas V and CST-100 duo (very probably) hides a BIG BUG that may kill the full project before kill a crew.

I don't use Facebook or any of the other reply methods on that web site, so I wasn't going to create an account just to reply to this guy.  Anyone see this?  Anyone care?  No one else has replied over there, so it may be just a troll, but it caught my interest.

Just more ramblings from a well known troll. I wouldn't even bother replying, logic doesn't work on that guy.

Yep, sounds like the Italian guy. He's banned from most forums, including here, and has resorted to the comment sections of news articles (part of the reason we don't use that format).

Moving on.

it seems that the mentioned website also has all the rocketcam footage of this flight for their subscribers. Whats up with that footage going exclusively to some site? I didn't find that footage from youtube either....

Sheesh. If I had to pay *someone* for that footage, I'd rather pay ULA directly than some third party.

Oh well.

I saw that, I wonder if they get it via their building in the KSC media area?

I can't understand ULA giving it to them specifically.

Boeing-built Legacy UHF Payload Successfully Operating on MUOS-1 Satellite

Modernizes UHF communications capability for US Navy
 
EL SEGUNDO, Calif., July 24, 2012 -- Boeing [NYSE: BA] today said that its legacy communications payload onboard the Lockheed Martin-built Mobile User Objective System (MUOS-1) satellite has passed all on-orbit tests.
 
MUOS-1 was launched on Feb. 24 from Cape Canaveral Air Force Station, Fla., on an Atlas V launch vehicle. It is the first of five satellites being built by MUOS prime contractor Lockheed Martin, which subcontracted with Boeing in 2004 to build, test and deliver the legacy ultra-high-frequency (UHF) communications payload. The UHF payload enables the U.S. Navy to use existing UHF ground- and space-based communications systems, extending the utility of the current system with an affordable and proven communications payload.
 
"The success of the MUOS-1 legacy payload demonstrates Boeing's ability to design and deliver UHF payloads that meet the warfighter's increasing need for satellite communications," said Craig Cooning, vice president and general manager of Boeing Space & Intelligence Systems. "The UHF radio frequency, which is not blocked by jungle foliage, inclement weather or urban terrain, meets a critical requirement for military personnel."

Aviation Week Article indicates that while operational, not everything is yet operational.
