Later this afternoon, join us for live reports throughout the countdown to the #DeltaIVHeavy #NROL44 launch. We'll be playing countdown trivia for ULA swag packs. Coverage begins at 5:30pmEDT (2130 UTC). Liftoff is targeted for 2:12amEDT (0612 UTC).

We develop, launch & operate sophisticated overhead intelligence collection systems to provide near real-time imagery & signals intelligence to our DoD and IC partners. #NROL44 will be the agency's 4th launch of 2020 in support of that crucial national security mission.

Another great idea from you guys... implemented.  Tonight's launch is the 385th in the Delta Rocket family, beginning with Thor-Delta in 1960.  Each of the 5 remaining DeltaIV-Hvy's will carry this badge.

ЦитатаРакета Delta IV стартует на орбиту с гигантским разведспутником США
27.08.2020 0:00:03

Вашингтон. 27 августа. ИНТЕРФАКС - Тяжелая ракета-носитель Delta IV в четверг должна вывести на орбиту секретный спутник NROL-44 Национального управления военно-космической разведки США (NRO), сообщила компания-оператор United Launch Alliance (ULA).

Запуск трехступенчатой ракеты, принадлежащей ULA - совместному предприятию корпораций Boeing и Lockheed Martin, планируется осуществить в 2:12 по времени Восточного побережья США (9:12 мск) со стартового комплекса SLC-37 на авиабазе ВВС США на мысе Канаверал в штате Флорида.

О целях, орбите, размере и других характеристиках секретного американского спутника NROL-44 официально не сообщается. Миссия и возможности спутников данного типа строго засекречены.

Между тем, по словам бывшего сотрудника NASA Дэвида Бейкера, знакомого с программой NRO, речь идет о запуске американского космического аппарата Orion, также известного как Mentor или Advanced Orion - серии американских спутников, предназначенных для радиоэлектронной разведки.

"Он весит более 5 тонн, оснащен огромной параболической антенной диаметром более 100 метров, которая раскрывается на орбите", - сказал эксперт. По его словам, гигантский спутник размером с автобус будет выведен на экваториальную орбиту высотой 36 тыс. км.

Основная задача нового американского спутника - перехват телеметрической информации и прослушивание каналов связи геостационарных спутников.
 Скрытый текст:
На геостационарную орбиту с 1995 года уже было выведено семь подобных спутников, разработанных NRO при участии ЦРУ.

В настоящее время на орбите Земли находятся 49 космических аппаратов Национального управления военно-космической разведки США. Всего США располагают орбитальной группировкой в составе, по меньшей мере, 154 военных спутников.

По данным эксперта, по сравнению с США сегодня Россия располагает на орбите 71 военными спутниками, Китай - 63.

Welcome to Live Coverage!

From the Delta Operations Center (DOC) at Cape Canaveral Air Force Station in Florida, this is Delta Launch Control at T-minus 8 hours and holding.



The countdown is about to start for liftoff of the United Launch Alliance Delta IV Heavy rocket on the NROL-44 mission for the National Reconnaissance Office.

Launch is scheduled for 2:12 a.m. EDT (0612 UTC) from Space Launch Complex-37. This will be launch number 385 for the Delta rocket program.

The countdown will begin at 5:42 p.m. EDT from the T-minus 8 hour mark. Two pre-planned, 15-minute built-in holds scheduled in the count. One pause is reserved prior to fueling at T-minus 4 hours, 15 minutes, the other occurs prior to the terminal count at T-minus 4 minutes.

Countdown Begins!

Countdown clocks have started ticking at Cape Canaveral for tonight's Delta IV Heavy launch. We are just eight-and-a-half hours away from liftoff of the triple-core rocket on the NROL-44 mission for U.S. national security.

The application of power to the avionics aboard the Delta IV Heavy rocket is beginning at the start of the countdown. The equipment will be powered up for launch day testing and final preparations for fueling operations.

At Space Launch Complex-37, the Mobile Service Tower retraction to the launch position is scheduled to begin shortly. A check of the weather conditions will be made by mission managers five minutes from now.

Weather Acceptable for Tower Roll

Launch Weather Officer Will Ulrich from the 45th Weather Squadron here at Cape Canaveral has provided a forecast of conditions expected during retraction of the Mobile Service Tower away from the Delta IV Heavy rocket and the outlook for tonight.

Current conditions are favorable to proceed with tower roll, with winds within limits and no adverse weather in the area. Also, the weather for the rest of the evening hours when the vehicle will be exposed during fueling operations also poses no concern for lightning or high winds.

For launch at 2:12 a.m. EDT, meteorologists are predicting scattered clouds, good visibility, easterly winds of 10 to 15 knots and a temperature near 81 degrees F.

Overall, there is an 80 percent chance of favorable launch weather.

The primary concern will be any showers forming over the ocean and drifting towards the coast to violate the Cumulus Cloud Rule.

GO for Tower Roll

We have concurrence to retract the Mobile Service Tower following a engineering readiness poll by ULA Launch Director Lou Mangieri. That "go" has been passed to the launch conductor for implementation.

T-minus 7 hours, 12 minutes (L-7 hours, 42 minutes) and counting. The Delta IV rocket has been powered up for the NROL-44 launch.

The flight control operator in the Launch Control Center performed the power up. Soon, he will begin avionics testing while the rocket's Inertial Guidance and Control Assembly (INCA) flight computer is allowed to warm up. Later, the operator will conduce guidance system testing and steering checks of the engine nozzles prior to cryogenic fueling.

MST jacking is underway. Using 40 hydraulic cylinders at pressures nearing 3,500 psi, the tower will be raised a few inches in preparation for the roll.

A short time ago, the tie-down clamps at the base of the Mobile Service Tower were opened so technicians could proceed to hydraulically raise the gantry for the rollback. These large claw-like devices secure the MST to anchor points on the pad surface.

MST Roll is Underway

This is Delta Launch Control. Retraction of the Mobile Service Tower is in progress at Space Launch Complex-37.
 
First motion occurred at 6:47 p.m. EDT (2247 UTC).

An undercarriage transport system with drive trucks in all four corners of the MST is moving the 33-story building at a top speed of 0.25 miles per hour.

The MST has moved 25 feet clear of the rocket thus far.

The gantry stands 330 feet tall, weighs nearly 10 million pounds and is the integral element that enables vertical integration of payloads atop the Delta IV Heavy. The tower is being wheeled on rail tracks about the length of a football field away from the rocket for tonight's scheduled launch.
