WGS-9 is loaded on to an Air Force C-17 to be flown to Florida in preparation for its scheduled March 8 launch from Cape Canaveral Air Force Station. WGS-9 will provide additional communications capabilities to both U.S. forces and its international partners.

Delta IV to Launch WGS-9 for the U.S. Air Force

 A United Launch Alliance Delta IV Medium+ (5,4) rocket will launch the ninth Wideband Global SATCOM (WGS-9) mission for the U.S. Air Force.


Date/Site/Launch Time: Wednesday, March 8, 2017, from Space Launch Complex (SLC)-37 at Cape Canaveral Air Force Station, Florida. The 121-minute launch window opens at 6:35 p.m. EST.

Live Broadcast: Tune in to ULA’s live launch day broadcast beginning at 6:15 p.m. EST.

Mission Description: WGS satellites are important elements of a new high-capacity satellite communications system providing enhanced communications capabilities to our troops in the field. WGS has 19 independent coverage areas, 18 of which can be positioned throughout its field-of-view. This includes eight steerable/shapeable X-band beams formed by separate transmit/receive phased arrays; 10 Ka-band beams served by independently steerable diplexed antennas; and one transmit/receive X-band Earth-coverage beam. WGS can tailor coverage areas and connect X-band and Ka-band users anywhere within its field-of-view. The X-band phased array antenna enables anti-jam functionality without sacrificing performance.

Launch Notes: WGS-9 will mark the seventh flight of the Delta IV in the Medium + (5,4)configuration; all launches in this configuration have delivered WGS missions to orbit. This mission also will be the 35th launch of the Delta IV since its inaugural launch in 2002.

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 #WGS9 and #DeltaIV

Go Delta! Go WGS-9!

Apologies for the delayed posting:
From the SFN article Atlas 5 and Delta 4 achieve milestones in parallel on the same morning, dated January 12, 2017, and as of January 12:
Quote
Meanwhile, the two-stage Delta 4 rocket was moved from its Horizontal Integration Facility to the launch pad yesterday and then raised vertically this morning, achieving the Launch Vehicle On Stand milestone.
<snip>
In the coming days, four strap-on solid rocket boosters will be installed to the Delta 4’s first stage. The payload will be attached in late February.
<snip>
WGS 9 was built by Boeing for the U.S. military’s worldwide communications network. But it was funding from Canada, Denmark, the Netherlands, Luxembourg and New Zealand that paid for the satellite’s construction as part of an international agreement.

The partner nations bought the satellite in exchange for access to the entire constellation, similar to the groundbreaking deal with Australia that paid for the construction and launch of WGS 6.

And, a revision to the ULA launch announcement, Delta IV to Launch WGS-9 for the U.S. Air Force, regarding timings:
Quote
Date/Site/Launch Time: Wednesday, March 8, 2017, from Space Launch Complex (SLC)-37 at Cape Canaveral Air Force Station, Florida. The 65-minute launch window opens at 6:48 p.m. EST.

Live Broadcast: Tune in to ULA’s live launch day broadcast beginning at 6:28 p.m. EST.

Question 1: When is the Wet Dress Rehearsal?  Or did it already happen?

Question 2: When will the payload be attached?

Delta 4 receives communications satellite payload for launch into space
Quote
Since rolling from its hangar a month ago, the Delta has undergone attachment of the four solid boosters and a pre-launch testing campaign. A fueling exercise was performed just last week.

EDIT: Added
Quote
The satellite was flown to Florida in early January from Boeing’s manufacturing facility in El Segundo, California. After arriving, it was taken to the commercial Astrotech processing facility to undergo pre-flight preps.

Final testing, loading of maneuvering propellant and encapsulation in the Delta 4’s nose cone was accomplished with the satellite.

According to the Astrotech web site, http://www.astrotechspaceoperations.com/mission-history , all of the WGS satellites have been processed at their Titusville location.

(It's a very neat list!)

In case you didn't know that the United States Air Force has been serving America for 70 years, we put it on a rocket and we're launching it on March 8 at Cape Canaveral Air Force Station. Want to follow the launch? Check out our 45th Space Wing at Patrick Air Force Base, Fla.'s Facebook page. Want to know more about our mission and the #WGS9 payload?

Also on the official ULA site:

(Update: March 4, 2017, 2 p.m. EST:) The launch date for a United Launch Alliance Delta IV carrying the WGS-9 satellite for the U.S. Air Force is no earlier than March 14. The team is actively working to resolve a Delta IV first stage booster issue discovered during standard prelaunch inspections. This additional time will allow the ULA team to ensure all systems are operating nominally prior to launch. A new launch date will be released once it is established. The Delta IV will lift off from Space Launch Complex-37 at Cape Canaveral Air Force Station in Florida.

Mission booklet posted at: http://www.ulalaunch.com/uploads/docs/Mission_Booklets/DIV/div_wgs9_mob.pdf

Interesting change of procedure, now noted in the mission booklet: The DCSS will be de-orbited into the western Pacific Ocean at the end of the mission, as it was at the end of the WGS-8 mission.

It was for WGS-8 as well.  I never looked at the booklet to see if that was mentioned or not.

WGS-8 booklet ends at spacecraft separation. It also doesn't have the orbit diagram.

Sorry, my mistake.  Thank you for catching it.
Reviewing, DCSS de-orbit was mentioned near the end of the WGS-8 launch thread: https://forum.nasaspaceflight.com/index.php?topic=40988.msg1617931#msg1617931.

So, SpaceX Echostar 23 is on March 14th, this flight is on March 14th, and Cygnus on a 401 is on March 19th?  Something has to give.  Have I missed it?

Launch Dates (EDT), as of this post
Echostar 23, March 14
WGS-9, TBD
Cygnus OA-7, March 21

My speculation follows.

Given that a range reset takes 2 days,

IF Delta IV and WGS-9 are ready for launch in the days immediately following March 14,

AND IF there are no other impediments, such as going into support staff overtime pay, or support staff rest periods between launches (I don't know),

THEN WGS-9 could launch on March 17 or 18.

Speculation concluded.

Emotional comment: A 1-2-3 launch cadence like that would be COOL!  8)
