This forward module validation test is fun to see. Our four fins on New Glenn are about the size of a car—roughly 16 feet long at the base and sticking out 6.5 feet from the body of the rocket. They’re responsible for steering the rocket on ascent and descent. Most of the structure is aluminum, which is protected from reentry heating by a durable fabric thermal protection system we invented and refer to internally as ‘Comet.’ The aerodynamic forces pushing on the fin during flight are roughly equal to the weight of a 737 aircraft. #newglenn Blue Origin

Another one in the books - the New Glenn team just finished NG-2's aft module activation test. This test activates the hydrogen peroxide system that powers the aft module hydraulics and conducts a shortened mission simulation of the integrated system. The four auxiliary power units, or APUs, produce a combined peak of 1,000 horsepower to drive the hydraulic pumps, roughly equivalent to the power of a modern F1 car. Next, we will mate the aft module to the rest of GS1 and install our seven BE-4 engines.

Launch table is out. The two-million-pound launch table is heading to the Integration Facility for inspection and adjustments to support our future ConOps. Once reinstalled at the pad, it'll be outfitted with the first stage aft umbilicals and tied into the water system, which delivers water injection just below the engine nozzles.

We're not rebuilding the same pad for New Glenn. We're moving to a horizontal/vertical hybrid configuration to get us flying again this year at 36A. We were already working on something similar for 9x4 at 36B. Let me explain what that means. We mate the stages horizontally in the Integration Facility (IF). Then we bring the integrated vehicle out to the pad, use a crane to perform the vertical breakover, and mate the payload once New Glenn is vertical. This new ConOps has the added benefit of increasing our flight cadence as well.

Some questions have come up on the launch bridge. It is in good shape and we will reuse. Three cranes are positioned to help lift the almost four-million-pound launch bridge and the two-million-pound launch table out of our flame trench and onto self-propelled modular transporters. Last night, the launch bridge was removed. The launch table is up next. Enjoy the crane ballet.

Quite a sight to see the progress this team has made since May 28. Wreckage recovery from start to finish was completed in 9 days, and all debris has been cleared from Launch Complex 36. Huge shoutout to the team who have been working 7x24. We have started reconstruction and still plan to fly again this year. Will have more details on the new conop soon.

I've come to appreciate boring hotfires. Our BE-7 team recently completed a 2,500 second hotfire test at 10klbf on a development engine, setting the record for the longest-duration turbo pump-fed liquid rocket engine hotfire. This built on some of the most rigorous testing in the history of propulsion, with the previous record set by the RS-25 engine that powered the Space Shuttle. They recorded two 2,017 second tests in 1988. It's not lost on us that we're following a path those engineers blazed, and we're grateful for it. Grab the popcorn and enjoy watching 41 minutes of hotfire goodness.

600+ feet of crane assembled incredibly fast by the team. We will start pulling down the tower (segment by segment) so we can modify each piece in parallel.

Cool video of New Glenn’s fairing re-entry. For this flight we installed an exo-atmospheric reaction control system (RCS) in the fairing to control re-entry and enable recovery of the fairing. We’re planning a parachute recovery later this year, and the data from these fairings gives us the learnings needed to develop and refine that capability.

By providing both propulsion for delivery and Earth communications, Blue Ring MTO dramatically simplifies requirements for orbiters and landed assets at Mars, allowing them to focus on exploration, science, and scouting rather than basic infrastructure. Next-generation high-resolution imagery, weather and dust storm monitoring, and ice mapping for fuel resources and ice science are essential for enabling human landing and advancing Mars understanding. Blue Ring MTO’s infrastructure significantly reduces the complexity, cost, and risk of these missions, enabling swarms of lower-cost, smaller missions to perform next-generation science at Mars.

"Never Tell Me The Odds" is back. Team Blue inspected every system, completed refurbishment, and certified it for flight. Proud to put a flight-proven booster to work for AST SpaceMobile on NG-3. Enjoy this fun video of us moving the integrated vehicle to the Transporter Erector (TE).

Fun video showcasing "No, It's Necessary" lifting on the Transporter Erector. Next stop integrated hotfire. "Never Tell Me The Odds" is in the house, too (well into it’s refurb cycle)

With rocket engines, boring is good. To that end, please enjoy this 1,030-second (17+ min!) BE-7 engine burn. This test represents the Apogee Raise Maneuver or ARM burn for our Blue Moon Mark 1 Lunar lander, plus margin, the longest burn required by the mission to reach the Moon. You may have noticed that the engine for this test does not have a nozzle. BE‑7 is tested in both vacuum and atmospheric conditions. This test was at GEEx—our atmospheric test position in West Texas.

In a recent hotfire our BE-3U engine reached more than 211,500 lbf thrust. That makes BE-3U the highest thrust-to-weight hydrogen engine in history, at more than 90! Here is the video of that test for your enjoyment.

Why do a little science when you can do a lot of science? Our Mars Telecommunications Orbiter, based on our existing Blue Ring vehicle, meets the urgent need for communications, navigation, and relay while also flying up to 500 kg of science instruments to Mars. With this capacity, we can deploy two ESCAPADE-class spacecraft from our orbiter or 10+ CubeSats and still host onboard instruments like a comprehensive science package to monitor the Martian atmosphere’s interaction with the solar wind.

Meet our second booster, with all modules mated: “Never Tell Me The Odds.” I think the odds of landing this booster are a lot better than 3,720-to-1. Both strakes are in place, and BE-4 installation is well underway. Great job by the team as we continue getting our second booster ready for launch.

Love seeing New Glenn's seven BE-4 engines come alive! Congratulations to Team Blue on today's hotfire. We extended the hotfire duration this time to simulate the landing burn sequence by shutting down the non-gimballed engines after ramping down to 50 percent thrust, then shutting down the outboard gimballed engines while ramping the center engine to 80 percent thrust. This helps us understand fluid interactions between active and inactive engine feedlines during landing. Next, we will mate NASA's ESCAPADE payload to the launch vehicle and enter final preparations for launch.
