According to this website: https://www.niferry.co.uk/stena-confirm-the-sale-of-stena-carrier-and-stena-freighter-to-unknown-buyers/ …, @blueorigin has acquired "Stena Freighter." It would seem this is the ship they will modify to use for #NewGlenn landings!

My article on how this fits into Blue Origin's near future plans:

Blue Origin BE-4 Engine Compilation

Blue Origin

Опубликовано: 27 сент. 2018 г.

The BE-4 is our fourth-generation liquid rocket engine, made to take us into orbit and beyond.

The BE-4 uses oxygen-rich staged combustion of liquid oxygen and liquefied natural gas to produce 550,000 lbs. of thrust. Liquefied natural gas is commercially available, affordable, and highly efficient for spaceflight. Unlike other rocket fuels, such as kerosene, liquefied natural gas can be used to pressurize a rocket’s propellant tanks. This is called autogenous pressurization and eliminates the need for costly and complex pressurization systems, like helium. Liquefied natural gas also leaves no soot byproducts as kerosene does, simplifying engine reuse.

United Launch Alliance has selected Blue Origin’s BE-4 as the engine that will power the Vulcan rocket's first stage. The announcement ends the need for the Russian made RD-180 on their next-generation vehicle Vulcan with the American-made BE-4.

Интересно, до какой величины земной тяги удастся Безосу довести ВЕ-4. Насчет проектного значения - 245 тс есть сомнения. А хотелось бы посмотреть на движок с земной тягой более 210 тс на горшок.

RS-68A чем не устраивает?

Уточняю, я имею ввиду пару метан(СПГ)+кислород, на керосине никто вроде не собирается делать движок с земной тягой более 210 тс на горшок. Что касается пары водород+кислород, там как то сумели пойти дальше, подавив ВЧ-колебания, возможно сказалось соотношение компонентов. ИМХО.

New Glenn: The Road to Space

Blue Origin

Опубликовано: 16 янв. 2019 г.

Debuting from Launch Complex 36 at Cape Canaveral, Florida in 2021, New Glenn will serve commercial, civil and national security customers from around the world. Featuring a 7 meter fairing with more than 2X the available volume of any rocket flying today and twin BE-3U engines powering the most capable upper stage in the market, New Glenn can launch the full range of satellite payloads. Seven reusable BE-4 engines generating 3.85 million pounds of thrust power the first stage designed to launch 25 times and land safely down range on a moving ship. New Glenn is beginning to take shape at our state-of-the-art rocket factory. Visit us at www.blueorigin.com to learn more.

New Shepard Flight History: Missions 1-9

Blue Origin

Опубликовано: 16 янв. 2019 г.

The more we fly the better we get. Safety and reliability are paramount. Our rigorous test program with New Shepard is putting the vehicle through the paces. We have successfully completed several crew capsule escape tests showing that our astronauts will be safe in any phase of flight. In addition to our test program, our payloads program is driving more flights of the system as we iterate on operations and technology in preparation for human spaceflight. All the learnings from the New Shepard program are being flowed into New Glenn development as we scale up our capabilities to serve the orbital market.

Building the New Shepard Fleet

Blue Origin

Опубликовано: 23 янв. 2019 г.

When we delivered New Shepard PM 4 to our West Texas launch site in December, it was the first time we had two rockets in the barn in Texas. We’re building our fleet of versatile reusable launch vehicles step-by-step as we move towards operations.

Седина в бороду, а бес в ребро - разводится, потеряет половину состояния. И если с Шепардом планы не изменятся скорее всего, то вот с темпами отработки ВЕ-4 - вопрос, как и с NG.
P.S. Уж коль не в терпеж, шо нельзя втихаря??[IMG]

Blue Origin unveils lunar lander
by Jeff Foust — May 9, 2019

WASHINGTON — Blue Origin revealed new details about a lunar lander concept that the company’s founder says can support a human return to the moon by 2024.

At an invitation-only event here May 9, company founder Jeff Bezos unveiled a full-sized model of the Blue Moon lander the company has been developing, along with an engine named BE-7 that will power the spacecraft. “We’ve been working on this for three years,” he said after a theatrical curtain-raising to reveal the lander model a half-hour into his presentation.

The spacecraft is able to land 3.6 metric tons of cargo on the lunar surface, with a “stretch tank” version capable of landing 6.5 metric tons on the surface. The lander has a deck on the top for hosting payloads, and a davit, or crane, to lower them to the lunar surface.

The lander uses liquid hydrogen and liquid oxygen propellants, rather than storable hypergolics. “It’s very high performance,” he said of the choice of propellants. “Ultimately, we’re going to be able to get hydrogen from that water on the moon, and be able to refuel these vehicles on the surface of the moon.”

The liquid hydrogen in particular is used not just for fuel, but for other aspects of the vehicle. Boiloff from the liquid hydrogen can be used to keep the liquid oxygen tanks cold, he said. It will also be used for fuel cells that will produce electrical power for the lander instead of solar cells. “We chose hydrogen fuel cells for this vehicle rather than solar cells because we want to be able to survive the lunar night,” he said, which lasts for two weeks.

Those propellants will be used by a new engine, called BE-7, on the lander. The engine will be able to produce 10,000 pounds-force of thrust and is deeply throttlable. “We’re going to hot fire it for the first time this summer,” Bezos said. “The only reason we can do that is we’ve been working on it for three years.”

Bezos didn’t provide other details about the development of Blue Moon, including how close the vehicle is to a first flight or its development cost. Bezos took no questions from the media or other guests in attendance, including NASA officials, former astronauts and scientists.

Bezos though, did endorse the new policy announced by Vice President Mike Pence in March to land humans on the moon in 2024, and hinted that only Blue Origin is able to meet that deadline in terms of developing a lunar lander.

“I love this. It’s the right thing to do,” he said of the goal. “We can help meet that timeline, but only because we started three years ago.”

Blue Origin’s announcement comes as NASA looks to industry for concepts for lunar landers to achieve that goal. That includes plans to issue a broad agency announcement for integrated lunar lander designs. It wasn’t clear, though, if Blue Origin would be able to provide an ascent stage capable of carrying astronauts, since the Blue Moon lander is designed to carry cargo only.

Much of the speech focused on Bezos’ long-term vision of millions of people living and working in space, tapping the resources needed for humanity’s future. He also briefly touched upon development of the New Shepard suborbital vehicle and New Glenn orbital vehicle, but only reiterated current timelines that call for starting to launch people on New Shepard this year and carry out a first orbital launch of New Glenn in 2021.

ABC: Джефф Безос представил прототип аппарата для высадки на Луну

Посадочный модуль называется Blue Moon

НЬЮ-ЙОРК, 10 мая. /ТАСС/. Глава компаний Amazon и Blue Origin Джефф Безос провел в Вашингтоне презентацию прототипа космического аппарата для высадки на поверхность Луны. Об этом сообщил в четверг телеканал ABC.

"Настало время вернуться на Луну, на этот раз, чтобы остаться", - заявил Безос на закрытом мероприятии для журналистов и работников космической сферы. Он продемонстрировал на сцене макет в натуральную величину аппарата для высадки на естественный спутник Земли. Посадочный модуль получил название Blue Moon.

Разработка аппарата, как подчеркнул Безос, "велась на протяжении трех лет". По его словам, Blue Moon сможет совершать мягкую посадку на поверхность Луны, имея полезную нагрузку от 3,6 до 6,5 т, при этом на его крыше можно будет разместить луноход. Глава Amazon также заявил о том, что специально для посадочного модуля разработан двигатель, получивший название BE-7. Первый пробный запуск силовой установки будет проведен летом.

Ранее вице-президент США Майкл Пенс заявил о том, что "политикой нынешней администрации является возвращение американских астронавтов на Луну в течение пяти лет". В свою очередь, директор Национального управления по аэронавтике и исследованию космического пространства (NASA) Джим Брайденстайн отметил, что Соединенные Штаты установят свое постоянное присутствие на Луне. При этом, по его словам, "это не предполагает постоянного присутствия людей на поверхности Луны. "Это означает, что там будут наши роботы, луноходы, а также люди, которые будут возвращаться туда и обратно на продолжительное время, чтобы заниматься наукой", - пояснил глава американского космического ведомства.
