They look quite small. If they control their attitude and solar panels to avoid specular reflections, they will be hard to track.

It seems so.

Most sensitive part of their design no doubt.

I dont how many bays in the HIF were occupied at the time the pictures were taken. if I could its RS-68A engine number then I could figure it out. Nothing yet in any of the NSF sections as to which mission that stage is for. message some of the cape people or Jim Oberg and see if they know

This Delta should be moving from the HIF to the pad soon, yes?

(Also, from the information that I've been able to find, this will be the next-to-last use of the Medium+(4,2) version.  The last will be the first GPS Block IIIA launch in May 2017.)

I wonder if there is any possibility that this is carrying a so far undisclosed third payload like the original GSSAP launch?

I'm only aware of the GSSAP payloads being scheduled to ship together, unless another payload arrived and was escorted with payload flown on a previous mission.

Delta IV to Launch AFSPC-6

Delta IV AFSPC6 Mission Artwork
Rocket/Payload: A United Launch Alliance Delta IV Medium (4,2) will launch the AFSPC-6 mission for the U.S. Air Force.

Date/Site/Launch Time: Friday, Aug. 19, 2016, from Space Launch Complex (SLC)-37 at Cape Canaveral Air Force Station, Florida. 

Mission Description: AFSPC-6 will deliver two Geosynchronous Space Situational Awareness Program (GSSAP) satellites to near-geo­synchronous orbit. The twin GSSAP spacecraft, built by Orbital ATK, will support U.S. Strategic Command space enhanced awareness operations. Data from GSSAP will uniquely contribute to timely and accurate orbital predictions, enhancing our knowledge of the geosynchronous orbit environment, and further enabling space flight safety to include satellite collision avoidance.

Launch Notes: AFSPC-6 marks ULA’s 110th mission since the company was founded in 2006 and the seventh ULA launch of 2016. Two GSSAP satellites were previously launched aboard a ULA Delta IV Medium+ (4,2) rocket from CCAFS on July 28, 2014.

Launch Updates: To keep up to speed with updates to the launch countdown, dial the ULA launch hotline at 1-877-852-4321 or join the conversation at www.facebook.com/ulalaunch, twitter.com/ulalaunch and instagram.com/ulalaunch. Hashtags #DeltaIV and #AFSPC6.

Go Delta! Go AFSPC-6!

"Oculi nostri nisi" on the second patch comes from the Book of Numbers. It seems to be a kitchen latin translation for "only our eyes".

The two-faced character on the same patch could be Janus, the Roman God of passages.
That could be linked to the fact that the GSSAP satellites fly above and below the geo belt, thus looking both ways (like janus) at the satellites:
Quote
The GSSAP twins, built by Orbital Sciences Corp., will support U.S. Strategic Command space surveillance operations as a dedicated Space Surveillance Network (SSN) sensor, as well as providing assistance for the Joint Functional Component Command for Space (JFCC-Space) in its task of more accurately tracking and characterizing man-made objects in orbit. When operational, the highly maneuverable satellites will “drift” above and below the geosynchronous Earth orbit “belt” and will employ advanced electro-optical sensors to observe other objects in space. This data is expected to enhance the Air Force’s knowledge of the geosynchronous environment and enable the development of new safety systems, including collision-avoidance mechanisms. The GSSAP satellites will communicate through worldwide Air Force Satellite Control Network (AFSCN) ground stations and from thence to Schriever Air Force Base, near Colorado Springs, Colo.

Air Force satellite duo mated to Delta 4 rocket for next week’s launch

From the article:
The twin payloads, inside their payload fairing, was attached to the Delta IV on August 5.

Flight Readiness Review (FRR) successfully completed.

The upper stage will deliver the payloads to geosynchronous orbit (GSO).

[I believe Delta IV did the same for the GSSAP 1 & 2 launch.]

From the launch preview video. Shows a dual spacecraft, but I'm not sure if these are the actual spacecraft or just generic versions like in classified launches.

From the launch preview video. Shows a dual spacecraft, but I'm not sure if these are the actual spacecraft or just generic versions like in classified launches.

Actual.  Two spacecraft on this mission.

Curious why you say actual.  Have photographs been posted?

From the launch preview video. Shows a dual spacecraft, but I'm not sure if these are the actual spacecraft or just generic versions like in classified launches.

Actual.  Two spacecraft on this mission.

Curious why you say actual.  Have photographs been posted?

No. AF approved artist impressions.

45th SW supports successful Delta IV AFSPC-6 launch

By 45th Space Wing Public Affairs

CAPE CANAVERAL AIR FORCE STATION, Fla. – The U.S. Air Force’s 45th Space Wing supported United Launch Alliance’s successful launch of the third and fourth Orbital ATK-built Geosynchronous Space Situational Awareness Program satellites aboard a Delta IV rocket from Space Launch Complex 37B here at 12:52 a.m. ET.

The AFSPC-6 mission will deliver two GSSAP satellites into orbit to further the space situational awareness mission.  Operated by Air Force Space Command, the GSSAP System provides precise data seven days a week, 24-hours a day.  The satellites join a GSSAP constellation currently supporting U.S. Strategic Command space surveillance operations as a dedicated Space Surveillance Network sensor.

The GSSAP also supports the Joint Functional Component Commander for Space by collecting space situational awareness data, allowing for more accurate tracking and characterization of man-made orbiting objects. 

According to Brig. Gen. Wayne Monteith, 45th Space Wing commander and mission Launch Decision Authority, this launch is the culmination of many long hours and hard work by the entire mission team.

“Congratulations to the AFSPC-6 integrated team and all our mission partners on a successful launch that will enhance our capabilities in space situational awareness and our space-based space situational awareness architecture.” he said.  “Today’s mission is just another example of our unwavering focus on mission success and guaranteeing assured access to space for our nation while showcasing why the 45th Space Wing is the ‘World's Premiere Gateway to Space.’”

United Launch Alliance Successfully Launches AFSPC-6 Mission for the U.S. Air Force
Twin GSSAP Satellites Enhance Space Based Situational Awareness

Cape Canaveral Air Force Station, Fla., (Aug.19, 2016) – A United Launch Alliance (ULA) Delta IV rocket carrying the AFSPC-6 mission for the United States Air Force lifted off from Space Launch Complex-37 Aug. 19 at 12:52 a.m. EDT. This is ULA’s seventh launch in 2016 and the 110th successful launch since the company was formed in December 2006.

                “Thank you to the ULA, Air Force and industry partners for the outstanding teamwork and flawless execution that made today’s mission a success,” said Laura Maginnis, ULA vice president of Custom Services. “This morning’s AFSPC-6 launch is a prime example of why our customers continue to place their trust us to launch our nation’s crucial space capabilities.” 

This mission was launched aboard a Delta IV Medium+ (4,2) configuration Evolved Expendable Launch Vehicle (EELV) powered by one common booster core. The common booster core was powered by an RS-68A liquid hydrogen/liquid oxygen engine producing 702,000 pounds of thrust. A single RL10B liquid hydrogen/liquid oxygen engine powered the second stage. The booster and upper stage engines are both built by Aerojet Rocketdyne. ULA constructed the Delta IV Medium+ (4,2) launch vehicle in Decatur, Alabama.

The AFSPC-6 mission consists of twin Geosynchronous Space Situational Awareness Program (GSSAP) spacecraft, built by Orbital ATK. The new satellites will join the first two GSSAP spacecraft  launched approximately two years ago aboard a Delta IV launch vehicle. GSSAP is a space-based capability that collects space situational awareness data, allowing for more accurate tracking and characterization of man-made orbiting objects. It has a clear, unobstructed, and distinct vantage point for viewing resident space objects orbiting earth in a near-geosynchronous orbit without the weather or atmosphere disruptions that limit ground-based observations. The data from GSSAP greatly improves our ability to rapidly detect, warn, characterize and attribute disturbances to space systems in the geosynchronous environment.

ULA's next launch is the Atlas V OSIRIS-REx spacecraft for NASA. The launch is scheduled for Sept. 8 from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida.

        The EELV program was established by the U.S. 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 100 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.

For more information on ULA, visit the ULA website at www.ulalaunch.com, or call the ULA Launch Hotline at 1-877-ULA-4321 (852-4321). Join the conversation at www.facebook.com/ulalaunch, twitter.com/ulalaunch and instagram.com/ulalaunch.

A movie showing the arrival of AFSPC-06 with GSSAP3 and 4 at geosynchronous orbit, based on images taken by Scott Tilley.

The movie shows the stack moving towards apogee and the upper stage performing the circularization burn. After that, the upper stage performs two more smaller burns, probably separating the payloads in between, and then dumping the remaining fuel. The movies ends when twilight gets too bright.

Orbital ATK Satellite and Launch Vehicle Technologies Play Vital Role in Air Force Mission

Two Orbital ATK-Built Satellites Will Track In-Orbit Man-Made Objects for AFSPC-6 Mission

Dulles, Virginia 19 August 2016 – Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, announced today that two satellites the company designed, built and tested for the U.S. Air Force were successfully deployed following their launch aboard a United Launch Alliance (ULA) Delta IV rocket from Cape Canaveral Air Force Station, Florida, on August 19, 2016. The satellites were the third and fourth for the Geosynchronous Space Situational Awareness Program (GSSAP) and comprise Air Force Space Command Mission Number Six, or AFSPC-6.  In addition to the company-built satellites that were deployed, Orbital ATK also provided propulsion, key composite structures and other components on the Delta IV launch vehicle.

The Orbital ATK-built satellites will operate in near-geosynchronous orbit and collect Space Situational Awareness (SSA) data for more accurate tracking and characterization of man-made objects in Earth orbit. The goal of the program is to enhance the country’s knowledge of the geosynchronous orbit environment for more timely and accurate orbit predictions to improve space flight safety.

“This launch marks the deployment of the second set of satellites we have designed and built for the U.S. Air Force GSSAP program. Enhancing space situational awareness is a top priority for the Air Force Space Command, and once again we provided innovative, reliable and affordable products to support this vital mission,” said Christopher Long, Orbital ATK’s Vice President of National Security Systems. “Our industry leading satellite systems based on flight proven GEOStar, LEOStar, Cygnus and ESPAStar platforms are helping to reshape the boundaries of National Security Space and Civil Space.”

The first two GSSAP satellites built by Orbital ATK were launched July 28, 2014 on AFSPC-4, which included the Air Force Research Laboratory’s Automated Navigation and Guidance Experiment for Local Space (ANGELS) satellite, deployed from the AFSPC-4, EELV Secondary Payload Adapter (ESPA).  Orbital ATK was the project’s prime contractor responsible for overall system design and development.

Orbital ATK designed, manufactured, integrated and tested the GSSAP satellites at its state-of-the art manufacturing facility in Dulles, Virginia. The company’s facilities in Dulles, along with Goleta and San Diego, California, and Beltsville, Maryland provided numerous subsystems, including the satellite’s solar arrays, heat pipes, avionic boxes, flight computer, shunt regulator assembly, composite components and deployable structures.

Orbital ATK also made major contributions to the Delta IV launch vehicle, including the two 60-inch diameter Graphite Epoxy Motors (GEM-60) produced at its Magna, Utah, facility, where it has manufactured 82 GEM-60s for the Delta IV launch vehicle since the initial flight in 2002. In addition, Orbital ATK supplied 11 key composite structures for the Delta IV rocket and GEM-60 motors that were manufactured at its facilities in Iuka, Mississippi and Clearfield, Utah.

Additionally, Orbital ATK manufactured the propellant tank for the Delta IV upper stage roll control system at the company’s Commerce, California, facility, and designed and manufactured the nozzle for Delta IV’s RS-68A engine at its Promontory, Utah, facility. Orbital ATK also designed and produced the nozzle’s thermal protection material, which is capable of shielding the nozzle from the extreme heat of launch, when external temperatures can exceed 4,000 degrees Fahrenheit.

This would not be done with the RL-10.  It is has a minimum burn duration on the order of a few seconds.

Would the smaller burns be performed with DCSS RCS?

Considering it is a time lapse covering 10:42 to 12:06 over 23 seconds, so each second of video covers roughly 20 seconds. So how many seconds are those events in realtime?

Congratulations to ULA and USAF for the successful launch!

I noticed in the press kit that it says that the boosters are flying in a new configuration with one fixed and one vectorable nozzle. How did previous configurations fly?

In the two-booster system configuration, both motors utilise vectorable nozzles, while the four-booster system operates with one fixed and one vectorable nozzle per side.

[...] the boosters are flying in a new configuration with one fixed and one vectorable nozzle.

I suppose compared with two vectorable nozzles this provides a cost savings, and possibly also a reliability improvement. (The only components that can't cause a failure are the ones that aren't part of the system at all! ;) ) And the control logic change seems pretty safe to implement. I wonder though if this was somehow enabled by the move to RS-68A?

Watch the Solid Rocket Booster's, kick out some fireworks. We got this out a bit late. According to USA Today twin satellites designed to look for foreign space mines around US strategic satellites. Star Wars.

Interesting -- I watched the launch live, albeit at 720p resolution, and I don't recall seeing all of the incidents of big sparklies popping out of the solids at seemingly regular intervals.

There has always been that kind of thing from solids, but this seemed like a lot more sparklies than normal.  To the extent that, watching the replay here, I started to wonder if structure was coming off from the payload area...

Somehow, my computer can't handle 1440p resolution, which bothers me because that's the lowest resolution this video offers.
Click on the setting icon on the lower right of the video you can change the resolution to 1080P or lower that suits your PC.  See the picture attached for the list of resolutions available for this video.

Sorry; I was watching the video just after it was uploaded and 1440p was the lowest resolution available.
Because the Falcon Heavy Test Flight was successful, it has inspired thousands of people to consider changing the future of space travel.

The payloads were spotted in orbit
http://www.satobs.org/seesat/Aug-2016/0165.html
http://www.satobs.org/seesat/Aug-2016/0167.html

Paraphrasing from the two posts:
Mike McCants and Scott Tilley also note from Scott's position observations and aobservations of brightness variations of the 2 objects that the newly-emplaced satellites could also be observing MUOS 5.

The new GSSAP satellites location in geosynchronous orbit is near the same longitude as the apogees of MUOS 5 on August 23, 25, and 27 (substantial separation due to difference in orbital inclination).

Also the brightnesses of the GSSAP satellites changed, with the same pattern, during the MUOS 5 apogee passes.  The brightnesses peaked at the times of the MUOS 5 apogee passes--perhaps an artifact of the GSSAP satellites' attitude change to observe MUOS 5?

EDIT: Mike McCants posted in a follow-up at http://www.satobs.org/seesat/Aug-2016/0172.html that Scott Tilley's brightness observations spanned "many hours" per observing session.

Apparently this was mainly simply due to the changing
sun-satellite-observer phase angle.

Oops.  This was an incorrect speculation based on my incorrect
interpretation of Scott's observations.

http://www.afspc.af.mil/News/Article-Display/Article/1310272/two-new-satellites-now-operational-expand-us-space-situational-awareness/

PETERSON AIR FORCE BASE, Colo. -- The 1st Space Operations Squadron at Schriever Air Force Base, Colorado, accepted two new satellites into operation Sept. 12 to expand their Geosynchronous Space Situational Awareness Program’s ability to characterize and track objects in space to support a neighborhood watch out in orbit.

GSSAP provides enhanced space-based space situational awareness to improve the ability to rapidly detect, warn, characterize and attribute disturbances to space systems in the geosynchronous environment. This assists in the protection of the assets in space that affect many facets of daily life such as navigation and communication. GSSAP supports U.S. Strategic Command’s ability to collect data on man-made orbiting objects.

GSSAP became operational in September 2015, when the first two GSSAP satellites reached their Initial Operational Capability. The two newest satellites to the program, GSSAP 3 and 4, were launched into orbit Aug. 19, 2016, and have now finished their testing phase.

“GSSAP 3 and 4 will significantly enhance our ability to characterize objects on geosynchronous orbit,” said Gen. Jay Raymond, commander of Air Force Space Command. “This provides the awareness we need to successfully operate in space.”

This addition to GSSAP is vital to expand 1 SOPS’s space-based space situational awareness mission. It not only provides a significant improvement in space object characterization, but also in detecting threats. Because of its near-geosynchronous orbit, it has a clear and distinct vantage point to avoid the weather interruptions that can limit ground-based space surveillance systems.

The GSSAP satellite system can characterize objects in space to a very refined level. Being able to discriminate and characterize objects assists the U.S. and its allies in achieving responsible and safe use of space. The information obtained by this program provides robust spaceflight safety information and ensures free access to, and use of, space.
As space continues to become more congested and contested, GSSAP and other space situational awareness programs are paramount in deterring aggressive action in space. GSSAP continues to enable safe operations and protects U.S. and allied spacecraft by providing timely and accurate situational awareness. Ultimately, GSSAP and 1 SOPS enable a range of decisive responses that will render any counter-space threats ineffective.
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."
