FULL STORY ======================================================================

After years of development, Blue Origins semi-reusable heavy-lift orbital launch vehicle, New Glenn, is due to launch on its maiden flight on Jan. 12
at 1:00 AM EST (06:00 UTC) after recently completing its seven-engine
hotfire. The flight is set to launch a Blue Ring Pathfinder payload to demonstrate the capabilities of the companys future Blue Ring multi-mission space mobility platform. Blue Origin pushed the launch from Jan. 10 due to rough seas, which would have precluded a booster recovery.





New Glenn, named in honor of NASA astronaut John Glenn, was formally
announced by Blue Origin in September 2016. However, the design of the
vehicle began much earlier, in 2012, with the initial development of the companys BE-4 rocket engine. Early designs of the rocket included both a two-stage variant and a three-stage variant, as well as an upper stage that would be powered by a vacuum-optimized BE-4 engine, known as BE-4U. The
rocket was to fly from Launch Complex 36 (LC-36) at Cape Canaveral Space
Force Station. New Glenns initial design compared to other rockets. (Credit: Blue Origin)

By 2018, the rockets design had evolved from what was initially announced. Some of the changes included the upper stage swapping out its single BE-4U engine with two BE-3U engines, derived from the BE-3 engine that powers the companys New Shepard rocket, the addition of large fixed strakes to the first stage, and a much larger payload fairing. The three-stage variant of the rocket was canceled in 2019.

By this time, Blue Origin had constructed a large manufacturing facility at Space Floridas Exploration Park, just outside the gates of NASAs Kennedy
Space Center. Meanwhile, at Launch Complex 36 large-scale work was underway
to construct an entirely new launch pad for New Glenn. By late 2020 the complex received two massive 175-meter tall towers on either side of the launch pad, a 106-meter tall water tower, a 13 thousand square meter integration facility, and many other critical pieces of pad infrastructure required to launch such a vehicle.

In late 2021, a New Glenn first stage simulator emerged from the companys Florida factory. It shared roughly the same measurements and mass as a flight article and provided employees with experience when it came to handling such
a large vehicle. The simulator stage was transported from the factory out to the launch pad, a 37 km journey that involves many obstacles along the way.

At the launch pad, the simulator allowed Blue to practice handling and integrating the stage with a simulator second stage and fairings. This included the assembled vehicle being mated with the transporter erector and rolled out to the launch pad.

The first sighting of a complete New Glenn booster tank module came in late 2023 outside of the companys factory. This section of the vehicle would serve as a pathfinder stage and undergo cryogenic testing at LC-36 in early 2024. Following several rounds of testing the pathfinder stage was rolled back to the factory, and the tank section was to be used for a future operational mission.

The next large milestone came in September when the second stage for the first flight of New Glenn was hotfired on the pad. The test involved a 15-second firing from the stages twin BE-3U engines, gimballing of the engines, as well as the stage using its tank pressurization control system which uses helium to keep the onboard liquid hydrogen and liquid oxygen pressurized in flight.

Following this successful test, the first stage for the inaugural launch rolled from the factory in late October. The booster playfully named So Youre Telling Me Theres a Chance was the first fully complete stage, including its seven BE-4 engines. The vehicle was moved to integration facility LC-36 where it would be mated with its second stage and a payload fairing before going through testing on the pad.

After rolling out the integration facility for the first time on Nov. 20,
New Glenn went through several tests on the launch pad to validate vehicle
and ground systems while in a fully integrated configuration. This included tanking tests, a wet dress rehearsal, and a hotfire, also known as a static fire. New Glenn standing at LC-36 before preflight testing. (Credit: Blue Origin)

The tanking tests were used to demonstrate the ability to flow propellants from the launch pads ground support equipment into the rockets fuel tanks. This was followed by a full terminal count sequence which allowed for the testing of switching to and from the vehicles flight computer.

On Dec. 27, following the wet dress rehearsal, the first stage performed a 24-second long hotfire of its seven BE-4 engines, which included the engines firing at 100% power for 13 seconds. The test not only marked the first time BE-4s had been fired at LC-36 but also the first time seven of the engines
had been fired together. Next stop launch pic.twitter.com/GQFz4XxEt5

The test came just hours after the company received a Part 450 commercial space launch license from the FAA. The license, valid for five years, allows Blue Origin to launch orbital missions of New Glenn from Cape Canaveral Space Force Station, and land the reusable first stage on a landing platform in the Atlantic Ocean.

In the days following the successful test, New Glenn was lowered back to horizontal and rolled back into its integration facility. This expected rollback allowed teams to inspect the vehicle as its big test campaign and swap out the empty payload fairing for the flight variant that included the encapsulated Blue Ring Pathfinder payload. The flight-ready rocket is rolled out and went vertical on Jan. 9.

On launch day, New Glenns intended final orbit is approximately 2,400 km by 19,300 km inclined 30 degrees.

Dave Limp, CEO of Blue Origin, shared that the payload is equipped with storage and compute virtualization to demonstrate anomaly detection using machine learning. Its mission kit provides high-performance, radiation-tolerant compute and storage akin to todays cloud-based offerings. The payload is expected to communicate with ground stations located in Mingenew, Australia, Paumalu, Hawaii, and Pendergrass, Georgia.

landing on the recovery vessel Jacklyn , also known as Landing Platform
Vessel 1 , which will be positioned 620 km downrange from LC-36. Blue Origins recovery fleet in Port Canaveral. (Credit: Julia Bergeron for NSF)

After the upper stage separates, the booster will perform a reorient
maneuver to prepare for an exoatmospheric deceleration burn, slowing the
stage down before reentry by igniting three of the BE-4 engines. During re-entry, the vehicles two large strakes will provide lift and allow the booster to glide through the atmosphere, while the four actuating fins and reaction control system near the top of the stage will provide steering control.

During landing, a single BE-4 will ignite to slow the vehicle down and provide final guidance down to the surface of Jacklyn . During the landing burn, six landing legs hosted in the boosters aft module will deploy 14 seconds from touchdown and help provide a soft landing.

If So Youre Telling Me Theres a Chance does successfully land on Jacklyn, Blue Origin will become the second company to fly and land a reusable orbital class rocket booster, following SpaceX, who first landed a Falcon 9 booster over nine years ago in late 2015.

Following landing, Blue Origin will use a Recovery Remotely Operated
Vehicle, or ROV, to connect to the aft module of the booster. This system
will provide the vehicle with communication, pneumatic, and power links from Jacklyn by using a robotic manipulator arm. Given that the recovery crews aboard support vessel Harvey Stone will be over 8 km away, the ROV provides quick and safe access to the towering stage, especially during poor weather conditions.

Blue Origin has multiple New Glenn boosters and upper stages in production which will be used to form a fleet for the companys future missions including NASAs ESCAPADE, Blue Moon lunar landers, Amazons Kuiper constellation, and more.
