That article says FY 2018, which means the payload could fly in 2017.

The interesting thing is, that this time an Atlas-V(411) instead of the Atlas-V(401) was ordered

SBIRS-GEO has either gained some additional mass or an different orbital injection profile will be used.

It's possible the extra SRB is for increased performance to allow the Centaur to fully de-orbit into the ocean.

Thanks. That article says that SBIRS GEO-4 will launch in 2016, while SBIRS GEO-3 has been put in storage and will launch in 2017. That doesn't really make much sense to me and doesn't fit with the earlier information, so I think the 2016 date may be a typo.

Replying to an old comment here, but the Air Force announced that SBIRS GEO 3 and 4 would swap launch slots right around the time that article was published. The reason is that GEO-4 was ready in time for the GEO-3 launch slot, so this way they only need to transfer one satellite in and out of storage.

Can anyone clarify (confirm) whether GEO-3 and GEO-4 swapped launch slots or not?  The reason that I ask is that there is a patch available (ostensibly for GEO-3) that clearly reads GEO-IV in roman numerals. Was this patch released in error, or does it represent the actual payload? Forgive me for playing devils advocate...

SBIRS GEO Flight-4 arrives in Florida, Prepares for January launch

CAPE CANAVERAL AIR FORCE STATION, Fla. -- The U.S. Air Force's Space Based Infrared System (SBIRS) program completed a major program milestone October 31, successfully delivering a Geosynchronous Earth Orbit (GEO) satellite Flight-4 to Cape Canaveral Air Force Station, Florida.

"The delivery, launch, and successful operation of GEO Flight-4 will mark the fulfillment of the original SBIRS baseline constellation and reaffirm our commitment to provide our country, warfighters, and senior leaders with timely, reliable, and accurate missile warning and infrared surveillance information." said Lt. Gen. John Thompson, SMC commander and Air Force program executive officer for space.

The delivery of GEO Flight-4 sets the path for final checkout of the space vehicle before launch. The satellite will be processed at the Payload Processing Facility located at Cape Canaveral Air Force Station, Florida.

A combined government and contractor team is already executing the final ground activities including a Launch Base Confidence Test to verify satellite integrity after shipment, an intersegment test to verify communication compatibility from the satellite to the on-orbit operations center and the final battery reconditioning for launch. Following these activities, the satellite will be fueled and prepared for integration with the Atlas V rocket.

"Finalizing the preparations for the fourth launch of a SBIRS GEO satellite is a big deal" added Col. Dennis Bythewood, director of the Remote Sensing Systems Directorate. "The entire team understands how significant this is, and we're ready to make it happen." The GEO Flight-4 satellite is scheduled
to launch from Cape Canaveral in January 2018.

The satellite was transported from the Lockheed Martin satellite integration facility in Sunnyvale, California, via a C-5 Galaxy aircraft. The C-5 crew from the 22nd Airlift Squadron, Travis AFB, California, ensured the satellite was transported safely and according to the time sensitive schedule. The security support provided by the 129th Rescue Wing, California Air National Guard, was essential to the success of the mission.

"The safety of the SBIRS satellite was entrusted to the very best, and we are appreciative of the transport and security services provided by the entire government and contractor team," Lt. Gen. Thompson said.

The SBIRS constellation is designed to replace the legacy Defense Support Program satellite constellation. SBIRS will continue to provide significantly enhanced capabilities to support missile warning, missile defenses, battlespace awareness and technical intelligence missions.

SBIRS GEO Flight-4 satellite fueling operations authorized;
Prepares for encapsulation

CAPE CANAVERAL AIR FORCE STATION, Fla. -- Preparations for the January 2018 launch of the fourth Space Based Infrared System (SBIRS) Geosynchronous Earth Orbit (GEO) satellite, commonly called GEO Flight-4, are underway at Cape Canaveral, Florida.

Having verified satellite integrity after successful delivery from Sunnyvale, California to Cape Canaveral Air Force Station, Florida, the SBIRS team was approved to start fueling operations for GEO Flight-4.

Proper fueling is crucial to the mission team's efforts to use GEO Flight-4's satellite propulsion system to guide the satellite to its geosynchronous orbit following separation from a United Launch Alliance Atlas V rocket. The GEO Flight-4 space vehicle will be loaded with sufficient fuel to reach its intended orbit and to maintain its proper orbit over its design life of twelve years.

The SBIRS constellation is designed to replace the legacy Defense Support Program satellite constellation. SBIRS will continue to provide significantly enhanced capabilities to support missile warning, missile defense, battlespace awareness and technical intelligence missions.

Rocket and satellite preps on track for next Atlas 5 launch (https://spaceflightnow.com/2017/12/29/rocket-and-satellite-preps-on-track-for-next-atlas-5-launch/), December 29

Quote
The Atlas 5’s first stage was stacked on top of a mobile platform inside the Vertical Integration Facility at Cape Canaveral’s Complex 41 launch pad early last week. It was to be followed by the hoisting of the Atlas 5’s Centaur upper stage and a single strap-on solid rocket booster.

This paragraph is written in past tense.  Is the CCB + Centaur + single booster integrated as of Dec. 29?


Re: change of SBIRS-GEO launches from 401 to 411 launch configuration:
The interesting thing is, that this time an Atlas-V(411) instead of the Atlas-V(401) was ordered

SBIRS-GEO has either gained some additional mass or an different orbital injection profile will be used.

It's possible the extra SRB is for increased performance to allow the Centaur to fully de-orbit into the ocean.

Quote
The change will allow the Centaur upper stage to make a controlled de-orbit and re-entry after it releases the SBIRS GEO Flight 4 satellite, a measure to prevent the flight from adding to space debris in Earth orbit.

So, we should see NOTAMs/NOTMARs for the Centaur disposal as the launch date approaches.
Kudos to c3i's insight!

Not addressed in the article:
Will there be a WDR?  (I remember that NSF experts have commented that WDRs are no longer performed as Standard Operating Procedure for Cape launches of the 401 variety.  Does that extend to all 4x1 configurations?  I assume also that if the customer chooses to pay for a WDR, that supersedes ULA SOP.)

Hello all,

Kennedy just put launch tickets on-sale for the 2018-01-18 launch. LC-39 Observation Gantry tickets are $49 (in addition to getting into KSC) and Saturn-V Center tix are $20 (in addition to park fees).

If you have the chance definitely go for the LC-39 viewing. LC-39 to SLC 41 is a mere 2.3 miles. That is the closest the public is allowed to a launch anywhere in the US.

You can purchase online here https://www.kennedyspacecenter.com/launches-and-events/events-calendar/2018/january/rocket-launch-ula-atlas-v-sbirs-geo-4. (https://www.kennedyspacecenter.com/launches-and-events/events-calendar/2018/january/rocket-launch-ula-atlas-v-sbirs-geo-4.)

Sealed Up, Ready to Go: U.S. Air Force's SBIRS GEO Flight-4 Missile Warning Satellite Encapsulated for Launch

Current SBIRS' constellation continues to deliver outstanding infrared surveillance performance

CAPE CANAVERAL AIR FORCE STATION, Fla., Jan. 11, 2018 /PRNewswire/ -- The U.S. Air Force's fourth Space Based Infrared System (SBIRS) Geosynchronous Earth Orbit (GEO) satellite built by Lockheed Martin (NYSE: LMT) was encapsulated on Jan. 9. The SBIRS GEO Flight-4 satellite is now ready for its planned Jan. 18 launch from Cape Canaveral Air Force Station, Florida, on a United Launch Alliance Atlas V rocket.

During encapsulation, SBIRS GEO Flight-4 was sealed in its launch fairing, an aerodynamic, nose-cone shell that protects the satellite during launch. In the coming days, the fairing with the satellite enclosed will be mounted on top of the Atlas V rocket as launch preparations continue.

SBIRS GEO Flight-4 is the latest satellite to join the Air Force's orbiting network of satellites equipped with powerful scanning and staring infrared surveillance sensors. The sensors collect data for use by the U.S. military to detect missile launches, support ballistic missile defense, expand technical intelligence gathering and bolster situational awareness on the battlefield.

Back on the ground, a sophisticated new SBIRS ground control system serves as the nerve center for the entire SBIRS satellite constellation and receives large amounts of data from the satellites' powerful sensors. The SBIRS control system and its operators convert this data into actionable reports for defense, intelligence and civil applications.

"SBIRS provides our military with timely, reliable and accurate missile warning and infrared surveillance information," said Tom McCormick, vice president of Lockheed Martin's Overhead Persistent Infrared systems mission area. "We look forward to adding GEO Flight-4's capabilities to the first line of defense in our nation's missile defense strategy."

Lockheed Martin manufactured the SBIRS GEO Flight-4 satellite at its Sunnyvale, California, facility. The satellite was delivered to Florida on Oct. 31, 2017. 

Building on SBIRS
The Air Force's SBIRS program continues to grow resilient, persistent, space-based infrared surveillance capabilities.

The planned launch of SBIRS GEO Flight-4 comes just 12 months after the launch of SBIRS GEO Flight-3, which in March 2017 sent its first images back down to Earth in a milestone known as "first light." These two satellites join SBIRS' GEO-1 and GEO-2, which received Air Force Space Command Operational Acceptance in 2013, and have performance that matches, and in some cases exceeds, requirements.

The next SBIRS satellites, GEO-5 and GEO-6, will bring increased resiliency, production efficiency and the ability to add new advanced sensor suites to the constellation using Lockheed Martin's modernized LM 2100 satellite bus. In September, a system Critical Design Review for the modernized design for GEO 5 and 6 was conducted with the Air Force, authorizing the satellites to enter into the manufacturing and integration phase.

At the center of SBIRS is its ground control system, which receives and processes a vast amount of satellite data. In late 2016, the Air Force operationally accepted "SBIRS Block 10," a new control system developed by Lockheed Martin, which includes enhancements like faster data collection times, improved threat detections, and improved target tracking and infrared information to enable troops to see dimmer targets faster.

SBIRS Block 10 also provides the Air Force with greater efficiency by consolidated ground control for the legacy Defense Support Program, as well as SBIRS satellites and payloads in GEO and Highly Elliptical Orbits.

Looks like a giant Kryptonian eagle: able to fly in outer space, catch and grip missiles in its talons, and destroy missiles in flight with heat vision.

Can we assume it is a sentient being from Krypton, and not "merely" trained to perform martial feats?

What a great companion for the son of Jor-El!

Atlas V SBIRS GEO Flight 4 Mission Profile


United Launch Alliance
Published on Jan 16, 2018

An Atlas V 411 rocket will launch the SBIRS GEO Flight 4 mission for the U.S. Air Force from Cape Canaveral's Space Launch Complex-41. SBIRS, considered one of the nation's highest priority space programs, is designed to provide global, persistent, infrared surveillance capabilities to meet 21st-century demands in four national security mission areas: missile warning, missile defense, technical intelligence and battlespace awareness.

Quick error of the mission profile video:

Even though the launch footage correctly depicts a night launch, the model shown is wrong since the 411 config lifts off faster and leaves a smoke trail thanks to the AJ-60A SRB.

The interesting thing is, that this time an Atlas-V(411) instead of the Atlas-V(401) was ordered

SBIRS-GEO has either gained some additional mass or an different orbital injection profile will be used.

It's possible the extra SRB is for increased performance to allow the Centaur to fully de-orbit into the ocean.
Looks like you were right, as per the mission booklet and the NOTAMs, the Centaur upper stage will be de-orbited on this mission.

For prior missions, this customer preferred to place the expended Centaur in the designated disposal orbit (junkyard, from which stages slowly decay into reentry). On this flight, the SRB provides enough energy to allow Centaur to be immediately deorbited.

I’d turn the question around and ask what is wrong with taking the responsible course of action, especially if anyone knows about the growing clutter in orbit it’s the USAF.

The issue is less about junk in orbit (GTO orbits generally decay in a few months or years) and more about controlling where any debris will fall after surviving reentry.

This is a bit surprising because on previous missions - e..g SBIRS GEO-3 - NOTAMs were taken to imply that
an immediate Centaur deorbit was done. Maybe those NOTAMs were not actually related to the missions in question.
Shows the danger of overconfident interpretation!

Atlas has a number of mission profiles that reduce ∆V to GSO and leave the spacecraft in a high-perigee orbit.

For a supersynchronous transfer, excess performance goes to apogee, then inclination, and then perigee once inclination reaches around 20°.

There are two different long-coast profiles that use an elliptical parking orbit, putting the argument of perigee at 0° or 180°.

The 3-burn profile leaves a high perigee, since the third burn is an apogee burn.

(Cape Canaveral Air Force Station, Fla., Jan. 18, 2018)– The launch of a United Launch Alliance Atlas V carrying the SBIRS GEO Flight 4 mission was scrubbed today due to a ground issue associated with the booster liquid oxygen system.

The launch is planned for Friday, Jan. 19, from Space Launch Complex-41 at Cape Canaveral Air Force Station. The forecast shows a 90 percent chance of favorable weather conditions for launch. The launch time is 7:48 p.m. ET.

ULA are having no luck with groundside valves of late, are they?

The GSE glitches have not been limited to valves... seems that latest flows are much more troublesome than a few years back (where they seemed to go at opening of launch window regularly).

traveling launch team with decreased team size and possible decreased maintenance team could propagate an increase of such issues compared to the past.

Total speculation on my part, but drawing from life-experience...ULA may have traveled over an inflection point on the graph plot of efficiency vs. effectiveness.

I forgot to factor in the effects of a gradually increasing launch rate.

I guess the answer could come as the next few ULA launches occur and winter turns to spring...
Does a trend develop, or do we see a continuance of the efficient and effective launch campaigns that us in the peanut gallery have come to expect in the current decade?

ULA launch success statistics are the envy of the planet's launch providers...
