Raumfahrt - Jeff Bezos erste Orbital-Rakete - Blue Origin, New Glenn Update

.

14.09.2016

Early this morning, Jeff Bezos revealed plans for the next Blue Origin rocket, the New Glenn.

Unlike their New Shepard rocket, which is only capable of up-and-down suborbital launches, New Glenn will be the company’s first rocket capable of bringing payloads and humans into orbit around the Earth.

Similar to New Shepard, New Glenn is designed with a recoverable booster and is intended to be reused, marking an exciting development in the space industry. There are currently no reusable heavy-lift rockets operational today (although SpaceX’s Falcon Heavy is expected to take its first flight later this year).

The reveal of New Glenn was much anticipated. Back in June, Blue Origin broke ground on a new facility in Cape Canaveral specifically to develop orbital rockets. The site, which is about 75% of the size of SpaceX’s rocket facility in California, will be large enough to accommodate manufacturing, processing, integration, and testing of New Glenn.

Power To Go Orbital

New Glenn will make use of seven BE-4 engines burning liquefied natural gas and liquid oxygen. The second stage of the rocket will use a  single vacuum-optimized BE-4 engine.

Using the same booster, New Glenn could also be configured as a 3-stage rocket, capable of bringing payloads farther than low-Earth-orbit. The third stage would use a single vacuum-optimized BE-3 engine burning liquid hydrogen and liquid oxygen.

While the BE-3 engine is currently used on the New Shepard rocket, Blue Origin has been working with United Launch Alliance (ULA) to build the new, high-performance BE-4 engine since 2011. In addition to Blue Origin’s New Glenn rocket, the BE-4 will be used on ULA’s reusable Vulcan rocket currently under development and expected to fly in 2019.

Suborbital -> Orbital -> Lunar?

Today’s announcement reveals interesting insights into Blue Origin’s rocket-naming strategy and – potentially – what’s in store for Blue Origin’s future.

Their New Shepard suborbital rocket, which is still undergoing the necessary testing before capable of conducting commercial/crewed flights, is named after Alan Shepard, the first American to reach space. Shepard achieved this milestone on a suborbital flight in 1961.

“Building, flying, landing, and re-flying New Shepard has taught us so much about how to design for practical, operable reusability. And New Glenn incorporates all of those learnings.” Jeff Bezos, Founder of Blue Origin

New Glenn is named after John Glenn, the first American to complete an orbit around the Earth.

 

In an email to subscribers, Bezos stated that the next rocket down the line would be named New Armstrong, and added “But that’s a story for the future.” As the first person to step foot on the moon, a rocket named after Alan Shepard indicates a possible focus on human-rated rockets capable of lunar destinations.

If this is the case, however, it’s still many years down the road. New Glenn itself won’t likely take its maiden flight for a couple of years.

“We plan to fly New Glenn for the first time before the end of this decade from historic Launch Complex 36 at Cape Canaveral, Florida.” Jeff Bezos, Founder of Blue Origin

 

How Does New Glenn Compare To Other Rockets?

A good way to compare rockets is their payload capacity to various orbits (e.g. how much stuff can that rocket take to low-Earth-orbit, medium-Earth-orbit, Geostationary orbit, etc?). This calculation depends on a number of factors including the mass of the rocket, which we don’t yet know. But Bezos did provide New Glenn’s thrust capability, which is a good indicator of how capable New Glenn will ultimately be.

And at 3.85 million pounds of thrust the 2-stage New Glenn rocket will be more powerful than the most powerful rocket currently in operation – the Delta IV Heavy provided by ULA, which has a liftoff thrust of 2.1 million pounds.

SpaceX’s Falcon Heavy, however, will trump that capability with over 5 million poundsof liftoff thrust once in operation. The Falcon Heavy is scheduled to fly for the first time by the end of this year.

Even so, once Blue Origin gets New Glenn off the ground, they’ll be a provider of one of the most powerful rockets in the world. The fact that they have included reusability into this design is revolutionary. SpaceX, Blue Origin, and ULA all have plans to launch reusable heavy-lift rockets by the end of the decade, which marks an exciting change for the space industry.

The Times They AQuelle: TCre A Changin’

The combination of competition and reusable rockets are expected to bring launch prices down even further, making access to space more affordable for researchers and astronauts alike.

“Our vision is millions of people living and working in space, and New Glenn is a very important step.” Jeff Bezos, Founder of Blue Origin

The fact that the fifth wealthiest person in the world is among other entrepreneurs setting their sights – and betting their wealth – on finding new ways to make space exploration affordable is already proving to make waves in this industry.

GUADALAJARA, Mexico – Blue Origin’s New Glenn rocket isn’t due to go into orbit until later this decade, but its design has already been validated by computer simulations and three weeks of wind tunnel testing.

That’s the word from Amazon billionaire Jeff Bezos, who founded Blue Origin 16 years ago this month. In a pair of tweets, Bezos showed off a scaled-down version of the New Glenn, which will tower 313 feet high in its three-stage version.

The pictures follow up on Bezos’ unveiling of the design earlier this month. Bezos said the model has been tested at transonic and supersonic speeds, with “exciting results.”

 

Blue Origin has already gone through multiple uncrewed flight tests of its New Shepard launch system, which is designed to send a crew capsule on suborbital space trips that reach altitudes in excess of 100 kilometers (62 miles). Bezos says the most dramatic test yet is set for early October at Blue Origin’s launch facility in West Texas.

If all goes well, New Shepard could be flying passengers by 2018. The craft – which is built at Blue Origin’s headquarters in Kent, south of Seattle – is named after the late NASA astronaut Alan Shepard, who became the first American in space in 1961.

New Glenn is named after John Glenn, who took America’s first orbital trip a year after Shepard’s flight. It’s due to be built at a Blue Origin facility that’s now under construction near NASA’s Kennedy Space Center in Florida.

 

Blue Origin’s New Glenn program could challenge SpaceX’s line of rockets. Like SpaceX’s Falcon 9, New Glenn could put satellites into orbit and send space crews to the International Space Station. Its first stage packs more punch than a Falcon 9 but not as much as SpaceX’s Falcon Heavy rocket, which is currently under development.

Blue Origin’s president, Rob Meyerson, is due to provide an update on the company’s plans on Tuesday during a session at the International Astronautical Congress here in Guadalajara, just before SpaceX CEO Elon Musk unveils his plans for trips to Mars.

Maybe Meyerson will mention New Armstrong. That’s Bezos’ next, next rocket – named after Neil Armstrong, the first astronaut to walk on the moon.

You should be able to catch Meyerson’s talk as part of the IAC’s streaming video coverage. The session starts at 7:30 a.m. PT (9:30 a.m. CT) Tuesday, and Meyerson is due to go on at 8:45 a.m. PT (10:45 a.m. CT).
