Coming up on MES-3 for Centaur. This will be a one minute and 46.6 seconds burn, raising the perigee - or lowest point - of Centaur's orbit, to aid AEHF-5's service longevity in space (reduces the amount of fuel AEHF-5 must burn to reach geostationary orbit).

SPACECRAFT SEPARATION!

T+plus 5 hours, 40 minutes, 30 seconds. The Advanced Extremely High Frequency-5 communications satellite has been deployed into space by the Atlas V rocket's Centaur upper stage for U.S. national security.

AEHF-5 will join four sister-satellites in geosynchronous orbit to provide global coverage for survivable, protected, anti-jam communications to strategic commanders, nuclear forces and tactical warfighters on land, at sea and in the air.

United Launch Alliance Successfully Launches Communications Satellite for the U.S. Air Force Space and Missile Systems Center

Cape Canaveral Air Force Station, Fla., (Aug. 8, 2019) -- A United Launch Alliance (ULA) Atlas V rocket carrying the fifth Advanced Extremely High Frequency (AEHF) communications satellite for the U.S. Air Force Space and Missile Systems Center lifted off from Space Launch Complex-41 on August 8 at 6:13 a.m. EDT. This marked the 80th successful launch of an Atlas V rocket, which has successfully launched and precisely delivered the entire AEHF constellation on orbit. ULA has a track record of 100 percent mission success with 134 successful launches.

"The ULA and supplier teams continue to demonstrate the highest dedication to mission success as we overcame several technical issues during the last few weeks," said Gary Wentz, ULA vice president of Government and Commercial Programs. "Thank you to the entire team and our government mission partners for the outstanding partnership and teamwork to deliver these critical payloads to orbit."

Producing more than two and a half million pounds of thrust at liftoff, the Atlas V 551 configuration rocket is the most powerful in the Atlas V fleet. The 551 rocket has launched groundbreaking missions for our nation—from the critically important MUOS constellation to historic science missions including New Horizons, the first mission to Pluto and the Juno mission to Jupiter.

The AEHF system, developed by Lockheed Martin, provides vastly improved global, survivable, protected communications capabilities for strategic command and tactical warfighters.

This mission launched aboard an Atlas V 551 configuration vehicle, including a 5-meter large Payload Fairing (PLF) and standing at 197 ft. tall. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine. Aerojet Rocketdyne provided the five AJ-60A solid rocket boosters (SRBs) and RL10C-1 engine for the Centaur upper stage.

ULA's next launch is the GPS III SV02 mission for the U.S. Air Force Space and Missile Systems Center aboard the final Delta IV Medium rocket. The launch is scheduled for August 22 at Space Launch Complex-37 at Cape Canaveral Air Force Station, Fla.

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 130 satellites to orbit that aid meteorologists in tracking severe weather, unlock the mysteries of our solar system, provide critical capabilities for troops in the field and enable personal device-based GPS navigation.

Quicklook launch review

The traditional quick-look post-flight data review of today's mission has occurred at the Atlas Spaceflight Operations Center following the successful launch of AEHF-5 by the United Launch Alliance Atlas V rocket.

Today's launch represents the 134th successful mission for United Launch Alliance and our fifth for the Air Force Space and Missile Systems Center's Advanced Extremely High Frequency communications satellite series. This flight also marked the 80th mission for the Atlas V and continued its 100 percent success rate.

Liftoff occurred at 6:13:00.246 a.m. EDT, with winds of 13 knots from the southwest and a temperature of 75 degrees F.

The vehicle performed successfully during today's six-hour mission, which included three Centaur burns. The quicklook meeting also reviewed the onboard video camera footage recorded during spacecraft separation.

Engineers representing various launch vehicle elements offered brief synopses of system performance -- such as the engines, hydraulics, pneumatics and avionics. The vehicle performed nominally during its mission and injected the AEHF-5 payload into a good orbit.

The quick-look meeting received congratulatory speeches from company leadership and the customer. ULA officials expressed appreciation to the Air Force in being entrusted in launching this national asset.

Today's mission occurred on the anniversaries of five previous launches of ULA heritage vehicles, including Pioneer Venus Multiprobe mission that launched atop Atlas-Centaur AC-51 in 1978 to fire three small probes into the thick Venusian atmosphere and obtain measurements and NASA's Genesis solar wind sample-return mission, launching in 2001 atop a Delta II rocket, that captured particles streaming from the Sun and brought them back to Earth.

Our next mission is planned for Aug, 22 from Space Launch Complex-37 at Cape Canaveral Air Force Station in Florida when a Delta IV rocket launches the Global Positioning System III SV02 navigation satellite for the U.S. Air Force Space and Missile Systems Center.
