Cape Canaveral, Fla. – The United States has just added to its spy satellite network.
The United Launch Alliance (ULA) successfully launched its 12th Delta IV heavy rocket on Thursday evening (December 10) from the newly minted Cape Canaveral Space Force Station in Florida. . The huge rocket took off from the Lonna Complex-pm from here at 9 :: 0 E at night.
After months of delays, the launch went off without a hitch, including hardware issues and launch pad infrastructure issues.

Originally scheduled to take off on August 26, the NROL-44 mission was postponed for the first 24 hours at the customer’s request. Then, on August 27, the rocket was fueled to launch, but the countdown stalled due to a serious issue with the ground aeronautics control system. The second attempt on August 29 was canceled at the last second.
Plans to launch the mission on September 26 were canceled due to issues with the launch pad’s swing arm retraction system. The weather pushed the flight back to Sept.29, followed by Sept. 29. Automatically shut down on the 30th, when a sensor defect was found on the rocket’s boardboard computer. That issue caused a delay of several months.
The sky on the edge of space was clear crystals as tonight’s stars and constellations and even Mars appeared in the sky above the launch pad.
Rockets slowly launched into the night sky. The power of the rocket’s main engines kicks into gear and the rocket visually moves forward and roars from the sky.
ULA is currently developing its next pay generation launcher, the Vulcan Centurion, and is preparing to phase out its Atlas and Delta rocket families. Only four Delta IV heavy launches remain, with two to fly from California and two additional missions to explode from the Cape before the end of 2023.
As evidenced by the latest series of delays, the Delta IV Heavy Launch is nothing short of dramatic. It goes into orbit and literally releases itself into the fire seconds before leaving the pad. Due to its sheer size and weight, the rocket flies and appears to be slowly leaving the Earth behind.
Powered by three common core boosters and a cryogenic second phase, the Delta IV Heavy Lift packs a fairly punch, generating over 2 million pounds of thrust on the F. The triple-booster rocket is fueled by a combination of super-chilled liquid hydrogen and liquid oxygen oxygen.
Liquid hydrogen is incredibly flammable, so any extra gas is burned 14 seconds before the rocket’s sparkler-like igniter lifts off. This completely normal part of the luncheon makes the iconic (and dramatic) fireball specific to the delta.
In T-7 seconds, the Starboard booster engine is ignited, followed by the center and port engines two seconds later. The amazing ignition is designed to reduce the fireball ball produced by the rocket’s hydrogen burning engine.
Shortly after the liftoff, the vehicle conducts a “pitch over” maneuver, directing itself to the correct flight path and reducing the stress on the vehicle during the flight. Within just four minutes after the liftoff, the booster on both sides is stripped and the center booster and upper stage throttle for about 90 seconds before the main engine shuts down.
From this point on, it’s all up to the stage. The rocket’s nose cone, known as the payload fairing, is .5..5 minutes apart in flight, but, NROL-44 the is a mission for the NRO, which operates US spy satellites, so the exact time and location of the payload deployment Will not be disclosed.

Way to launch
The NROL-44 launch campaign really got off to a good start last summer, when three of the rocket’s usual core boosters arrived at ULA’s facilities here at Cape Canaveral. The trio was integrated with each other while the center rod was attached to the cryogenic upper stage. The upper stage is powered by a single aerojet RocketDin RL10B-2 engine, which imposes a secret payload into orbit after the booster is released.
A few months later, in November 2019, the rocket was turned into a vertical integration facility at Space Launch Complex-37 and its payload awaited to be mounted. But before that could happen, ULA engineers needed to get the rocket through its motion to make sure launch day would run smoothly.
In January 2020, the ULA completed a prelaunch test, which included a “wet dress rehearsal.” The vehicle was full of fuel, and the crew studied the launch day activities until the ignition. The rocket was then detonated and tied inside the mobile paver tower to await its payload, which was installed on July 27.
A dozen deltas
Today’s flight marks the 142nd successful launch for the ULA for its sixth mission this year and for the company since its inception in 2002. It is also the 12th Delta IV heavy flight. To date, eight rockets have been loaded for NRO. Other notable missions include sending NASA’s Orion capsules on a test flight to Earth orbit in December 2014, as well as launching the agency’s Parker Solar Probe in a mission to find the sun in August 2018.
It is also the Delta family’s 385th rocket to fly from Thor-Delta in 1960. To honor that legacy, UL CEO Tori Bruno Tweeted an image That was painted on the rocket. This image shows the concept of la 385 next to the rocket, inside the triangle, symbolizing the letter delta in Greek. All future Delta IV heavy rockets will see a variation of this badge, Bruno said.
Another great idea from you guys … implemented. Tonight’s launch is the 385th in the Delta Rocket family, which began in 1960 with Thor-Delta. Each of the remaining 5 Delta Ivy-Havi will hold this badge. pic.twitter.com/cq2rjFJ34oAugust 26, 2020
The remaining four are Delta IV heavy missions that will launch their own national security payload somewhere before 2023. The first of these is projected to take off from Vandenberg Air Force Base in California early next year. After that, there will be an additional mission from California as well as two more missions from Cape.
The Delta IV Heavy is the NRO’s preferred launch vehicle, as the rocket is essentially suitable for its scattered cargo. Reconnaissance payloads historically are incredibly heavy and bulky, just like starting a school bus, and are designed to fit exclusively with Delta IV Heavy.
That’s why the ULA uses an integration approach to attach and integrate payloads with its rockets. This technique is suitable for NROs; Its satellites are designed to be mounted on top of the rocket while it is still in a position, as opposed to horizontal integration practices.
But the Delta IV Heavy is not the only heavy volatile material on the market. SpaceX also has a giant rocket of its own called the Falcon Heavy.
The Falcon Heavy may overtake the Delta IV Heavy, but the larger payload ferring in the Delta is designed to hold larger, larger cargo. The Falcon Heavy is also currently relying on horizontal integration to mate its payload.
SpaceX has said it will offer more flexible transactions going forward, including the use of new integration methods as well as large payload ferries for military missions.
It could help snatch more launch contracts. In 2018, the Falcon Heavy signed its first military contract from the Air Force. 130 million has done well, and it is set to launch a military payload next year. But that’s not all. The Pentagon recently selected both ULA and SpaceX to share launch duty for its future military and NRO missions. The duo beat competitors Blue Origin and Northrop Grumman, each developing their own rocket.
ULA acquired a lion’s share, achieved 60% of the mission by 2027, while SpaceX will launch 40%. It is unclear whether the mission will launch on SpaceX’s Falcon 9 or Falcon Heavy, but part of the ULA expects to employ the company’s next pay-generation launcher, the Vulcan Centurion.

Rocket in 3D
In late August, ahead of the NROL-44’s originally planned lift date, the UAE estimated its history and future shining performance for its employees, VIPs and some members of the media on the rocket, while it was seated, entering its mobile service. Tower (MST). The video project was three years in production, and will showcase the company’s past, present and future.
“We are dreamers inspired by possibilities that have not yet been imagined. Believers are motivated to meet the potential of space,” the narrator said as an enthusiastic series of pictures of rockets in Amherst.
This was the first time 3D mapping was estimated on a real rocket. According to ULA officials, the project required many, many approvals, but in the end, the customer was really excited about it.
“The Delta IV Heavy is the largest vehicle in ULA’s fleet and is proven to be the toughest in our country,” Tony Tellianchich, ULA’s operations manager, told Space.com. “It has a legacy of successfully delivering payloads to the U.S. Space Force, National Reconnaissance Office fees and NASA.”
Teliasich explained that ULA’s launch services are helpful in saving lives, exploring the universe and connecting the world. So the new video was a way to highlight the company’s achievements and goals while also saluting space research.
“To tell a 3D projection story about the industry, the national security location and the future of space exploration, we needed a really big canvas – and the Delta IV Heavy certainly delivers,” he said.
The NROL-44 mission is the 30th mission the ULA has launched for the NRO. Other launches this year include a robotic X-spaceB B space plane as part of the US space force’s first official facial mission, as well as a Mars Persuasion Rover for NASA in July-July.
