Sunset Delta Set to Dazzle Cape with Mighty Air Force SatCom Launch March 18 – Watch Live

CAPE CANAVERAL AIR FORCE STATION, FL – As sunset dawns on the venerable Delta rocket program, the sole Delta slated to launch from the Cape this year is set to dazzle at sunset tonight, Saturday, March 18.

And the launch site is drenched with brilliant blue skies this afternoon as I watched the Delta rocket exposed to the heavens as the mobile service tower rolled away from on site at pad 37.

Florida’s Space Coast will light up with a spectacular sunset burst of fire and fury as a United Launch Alliance (ULA) Delta rocket roars to space with a super advanced tactical satcom for the U.S. Air Force that will provide a huge increase in communications bandwidth for American forces around the globe.

Blastoff of the Wideband Global SATCOM (WGS-9) mission for the U.S. Air Force is slated for 7:44 p.m. EDT on Saturday, Mar. 18, 2017 from Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida.

WGS-9 will be delivered to a supersynchronous transfer orbit atop a ULA Delta IV Medium+ rocket.

Thus ‘March Launch Madness’ continues unabated tonight – with a dizzying pace of launches.

Because it’s been barely two and a half days since a SpaceX Falcon 9 successfully dazzled sky watchers and launch enthusiasts on Thursday, March 16, just after midnight by delivering the EchoStar XXIII commercial television satellite to geosynchronous orbit – as I witnessed and reported on here.

So it’s past time to ‘get your ass to the Cape’ – because the weather is glorious in central Florida. And … a Atlas rocket is slated to launch in only five or six days – late next week! in six next Friday.

Saturday’s sunset launch window runs for one hour and 15 minutes from 7:44-8:59 p.m. EDT.

You can watch the Delta launch live on a ULA webcast. The live launch broadcast will begin approximately 20 minutes prior to liftoff at 7:24 p.m. EST here:

The weather forecast for Saturday, Mar. 18, calls for a 90 percent chance of acceptable ‘GO’ weather conditions at launch time.

The primary concern is for cumulus clouds.

In case of a scrub for any reason the chances for a favorable launch dip just slightly to 80% GO on Sunday, March 19.

WGS-9 and her two sisters are the most powerful US Air Force military communications satellite ever built.

WGS-8 was launched on a Delta in December 2016.

It is the ninth satellite in the WGS constellation that serves as the backbone of the U.S. military’s global satellite communications.

“WGS provides flexible, high-capacity communications for the Nation’s warfighters through procurement and operation of the satellite constellation and the associated control systems,” according to the U.S. Air Force.

“WGS provides worldwide flexible, high data rate and long haul communications for marines, soldiers, sailors, airmen, the White House Communication Agency, the US State Department, international partners, and other special users.”

The 217 foot tall Delta IV Medium+ rocket will launch in the 5,4 configuration with a 5 meter diameter payload fairing and 4 solid rocket boosters to augment the first stage.

The is the seventh flight in the Medium+ (5,4) configuration; all of which were for prior WGS missions.

WGS-9 also counts as the first of at least a trio of launches from the Cape this March- with the possibility for a grand slam fourth at month’s end – if all goes well with another SpaceX Falcon 9 launch from pad 39A.

ULA Delta IV Rocket Launches July 23 with USAF High Capacity Satcom: Watch Live

CAPE CANAVERAL AIR FORCE STATION, FL – A high powered military communications satellite for the US Air Force is now slated for launch on a United Launch Alliance (ULA) Delta IV rocket on Thursday evening, July 23, following a scrub called on Wednesday due to powerful thunderstorms passing too close to the Cape Canaveral launch pad in Florida.

Heavy rain and thunderstorms within range of the Delta IV launch pad at Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida, forced ULA to scrub the blastoff originally set for Wednesday, July 22.

Due to deteriorating weather, ULA technicians were had to stop processing the rocket for launch and were unable to fuel the propellant tanks. Predicted high winds were also a factor in the launch scrub.

The Delta IV liftoff with the Wideband Global SATCOM 7 (WGS 7) satellite was reset for Thursday, July 23, at 8:07 p.m. EDT

The window extends for 39 minutes until 8:46 p.m. EDT.

You can watch the Delta launch live on a ULA webcast that starts at 7:47 p.m. EDT here:

The weather forecast for Thursday July 23, calls for a 60 percent chance of acceptable weather conditions at launch time.

The $570 million WGS 7 satellite is part of a significant upgraded constellation of high capacity communications satellites providing enhanced communications capabilities to American troops in the field for the next two decades.

“WGS enables more robust and flexible execution of Command and Control, Communications, Computers, Intelligence,Surveillance and Reconnaissance (C4ISR), as well as battle management and combat support information functions,” according to ULA.

The Delta IV Medium+ rocket will launch in a 5,4 configuration with a 5-meter diameter payload fairing and four solid rocket motors augmenting the first stage core powered by a single RS-68 main engine.

The RS-68 burns cryogenic liquid hydrogen and liquid oxygen which generates about 702,000 lbf of thrust at sea level.

Fueling of the rocket has begun!
