CEO @BlueOrigin. Love space and consumer electronics. Let’s build a road to space for the benefit of Earth.

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.

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.

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)

"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).

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.

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.

Our Mars Telecommunications Network solution accommodates the proven Electra UHF radio with no modifications. Because we can operate Electra in a lower orbit, we're uniquely positioned to meet the essential need for reliable UHF relay from assets on the Martian surface or in the Martian atmosphere. That matters for ongoing missions like the Curiosity and Perseverance rovers, and also for future missions like Skyfall that need reliable communication with Earth without requiring unrealistically high power or high-precision antenna pointing.

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.

We hot fired New Glenn’s GS2 serial number five last night, with the BE-3U engines ramping up to 175K of thrust. Love seeing the continuous flow of GS2s on the Space Coast!

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.

New Glenn’s first and second stages are now mated – a big step toward launch. Here is a fun time lapse video (from the factory cameras) of us moving the integrated vehicle to the Transporter Erector (TE). The New Glenn simulator can be seen in the middle of the clip, an important part for ground support equipment validation. We will spend the next days on final checkouts and connecting the umbilicals. Stay tuned for rollout and hotfire!

BE-7 vacuum test. Engine in flight configuration with flight pumps, tank head start, and spark igniter. We’re currently hot-firing this engine five times a day. Full flow closed expander, specific impulse 460 seconds. Next stop, the Moon.

As New Glenn upends on the Transporter Erector (TE), the load shifts from the horizontal support system to the vertical supports around 74 degrees. Near 89.5 degrees, we pause for a final check, then pin the TE in place using clamps on the launch table that mate to the aft launch ring. Checkouts then hotfire…

Endurance, our MK1 lunar lander, has entered Chamber A for approximately 11 days of TVAC testing to simulate the extreme thermal and vacuum conditions it will experience in space and on the lunar surface. Thanks to the team NASA's Johnson Space Center for the collaboration as we reach this critical step on our path to the Moon.
