Space telescopes are a pretty amazing thing. By deploying an observatory to orbit, astronomers are able to take pictures of the Universe unencumbered by atmospheric disturbance. At the same time, they are very expensive to build, maintain, and launch into space. As the case of Hubble’s flawed mirror demonstrated, a space telescope also has to go through rigorous checks because of how difficult it becomes to service them after launch.
To address this, NASA is investigating the possibility of constructing future space telescopes in space. A key aspect of this involves a manufacturing technique known as Atomic Layer Deposition (ALD), a process where layers of material no thicker than an atom is deposited on a surface and then hardened in place. Now, a team of NASA-supported researchers has been given the chance to test ALD in a microgravity environment (i.e. space!)
Today’s breed of billionaire space entrepreneurs likes to keep us guessing, don’t they? Mr. Elon Musk is famous for announcing partial plans on Twitter, then leaving us to cajole the details out of him. Now, Jim Bezos, Amazon founder and Blue Origin visionary, is making us guess what an upcoming mysterious announcement might mean, all on the tails of another successful flight for New Shepard.
Blue Origin, the private aerospace company founded by multi-billionaire (and founder of Amazon) Jeff Bezos, is looking to make its presence felt in the rapidly expanding NewSpace industry. To this end, Blue Origin has spent years developing a fleet of reusable rockets that they hope will someday rival those of their greatest competitor, SpaceX.
So far, these efforts have led to the New Shepard rocket, which can send payloads (and soon, space tourists) to suborbital altitudes. In the coming years, Blue Origin hopes to go farther with their New Glenn rocket, a reusable launch vehicle capable of reaching Low-Earth Orbit (LEO). The company recently released a new video of the New Glenn, which showcased the designs latest features and specifications.
One of the greatest challenges of modern spaceflight is finding a way to make launching rockets into space commercially viable. Reduced costs will not only mean more launches, but the ability to conduct more ambitious programs in Low Earth Orbit (LEO) and beyond. To this end, many private aerospace companies are investing in reusability, where the first-stages of a rocket and even entire vehicles are retrieved after launch and reused.
In recent years, Elon Musk has become famous for his development of reusable first-stage boosters and fairings. But Blue Origin’s Jeff Bezos has also been no slouch when it comes to making the company’s fleet of rockets reusable. On Sunday, April 29th, the company is passing another milestone with the 8th test flight of the New Shephard rocket, an event which is being live-streamed.
As a fully reusable vertical takeoff, vertical landing (VTVL) space vehicle, the New Shephard is crucial to Blue Origins’ vision of commercial spaceflight and space tourism. Consisting of a pressurized capsule aboard a booster, the combined vehicle launches vertically and accelerates for two and a half minutes before the engine cuts off. The capsule then separates and floats into suborbit while the booster returns to Earth under its own power and with the help of parachutes.
Launch preparations are underway for New Shepard’s 8th test flight, as we continue our progress toward human spaceflight. Currently targeting Sunday 4/29 with launch window opening up at 830am CDT. Livestream info to come. @BlueOrigin#GradatimFerociterpic.twitter.com/zAYpAGWB8C
Named in honor of famed astronaut Alan Shepard, the rocket’s crew capsule has room for six people. These will consist of customers looking to take a flight to suborbital altitudes and experience the sensation of weightlessness. As they state on their website:
“The New Shepard capsule’s interior is an ample 530 cubic feet – offering over 10 times the room Alan Shepard had on his Mercury flight. It seats six astronauts and is large enough for you to float freely and turn weightless somersaults.”
The announcement for the 8th test launch came on Friday, April. 27th, when Bezos tweeted that “launch preparations are underway for New Shepard’s 8th test flight, as we continue our progress toward human spaceflight. Currently targeting Sunday 4/29 with launch window opening up at 830am CDT.” The launch would take place at the company’s suborbital launch and engine test site near the town of Van Horn in West Texas.
As with the previous New Shepard test launch, which took place on Dec. 12th, 2017, the crew for this mission would be the mannequin known as “Mannequin Skywalker” (check out the video of this flight below). As with the previous uncrewed flight, Mannequin Skywalker will be testing the capsule’s safety restrains in advance of a crewed test flight.
At 0526 (0826 PST), Bezos tweeted that the flight window – which was originally set for 0845 CDT (0630 PDT) – had been delayed due to thunderstorm over West Texas. At 0950 CDT (0750 PDT), Bezos issued a follow-up tweet that the liftoff target was now 1113 CDT (0913 PST). Live streaming will begin 15 minutes before the launch, which you can watch by going to Blue Origin’s website.
If successful, this launch test will place Blue Origin one step closer to conducting space tourism. As Bob Smith, the CEO of Blue Origin, recently indicated in an interview with CNBC, he hopes the company will begin these launches by the end of this year. In addition, he said that the company continues to pursue the development of engine technology, which it hopes United Launch Alliance will use on its Vulcan rockets as well.
Be sure to check out the live-steam of the launch, and feel free to enjoy this video of the New Shepard conducting a space tourism flight while you’re waiting:
On March 30, 2017, SpaceX performed a pretty routine rocket launch. The payload was a communications satellite called SES-10, owned by a company in Luxembourg. And if all goes well, the satellite will eventually make its way to a high orbit of 35,000 km (22,000 miles) and deliver broadcasting and television services to Latin America.
For all intents and purposes, this is an absolutely normal, routine, and maybe even boring event in the space industry. Another chemical rocket blasted off another communications satellite to join the thousands of satellites that have come before.
Of course, as you probably know, this wasn’t a routine launch. It was the first step in one of the most important achievements in space flight – launch reusability. This was the second time the 14-story Falcon 9 rocket had lifted off and pushed a payload into orbit. Not Falcon 9s in general, but this specific rocket was reused.
In a previous life, this booster blasted off on April 8, 2016 carrying CRS-8, SpaceX’s 8th resupply mission to the International Space Station. The rocket launched from Florida’s Cape Canaveral, released its payload, re-entered the atmosphere and returned to a floating robotic barge in the Atlantic Ocean called Of Course I Still Love You. That’s a reference to an amazing series of books by Iain M. Banks.
Why is this such an amazing accomplishment? What does the future hold for reusability? And who else is working on this?
Developing a rocket that could be reused has been one of the holy grails of the space industry, and yet, many considered it an engineering accomplishment that could never be achieved. Trust me, people have tried in the past.
Portions of the space shuttle were reused – the orbiter and the solid rocket boosters. And a few decades ago, NASA tried to develop the X-33 as a single stage reusable rocket, but ultimately canceled the program.
To reuse a rocket makes total sense. It’s not like you throw out your car when you return from a road trip. You don’t destroy your transatlantic airliner when you arrive in Europe. You check it out, do a little maintenance, refuel it, fill it with passengers and then fly it again.
According to SpaceX founder Elon Musk, a brand new Falcon 9 first stage costs about $30 million. If you could perform maintenance, and then refill it with fuel, you’d bring down subsequent launches to a few hundred thousand dollars.
SpaceX is still working out what a “flight-tested” launch will cost on a reused Falcon 9 will cost, but it should turn into a significant discount on SpaceX’s already aggressive prices. If other launch providers think they’re getting undercut today, just wait until SpaceX really gets cranking with these reused rockets.
For most kinds of equipment, you want them to have been re-used many times. Cars need to be taken to the test track, airplanes are flown on many flights before passengers ever climb inside. SpaceX will have an opportunity to test out each rocket many times, figuring out where they fail, and then re-engineering those components. This makes for more durable and safer launch hardware, which I suspect is the actual goal here – safety, not cost.
In addition to the first stage, SpaceX also re-used the satellite fairing. This is the covering that makes the payload more aerodynamic while the rocket moves through the lower atmosphere. The fairing is usually ejected and burns up on re-entry, but SpaceX has figured out how to recover that too, saving a few more million.
SpaceX’s goals are even more ambitious. In addition to the first stage booster and launch fairing, SpaceX is looking to reuse the second stage booster. This is a much more complicated challenge, because the second stage is going much faster and needs to lose a lot more velocity. In late 2014, they put their plans on hold for a second stage reuse.
SpaceX’s next big milestone will be to decrease the reuse time. From almost a year to under 24 hours.
Sometime this year, SpaceX is expected to do the first launch of the Falcon Heavy. A launch system that looks like it’s made up of 3 Falcon-9 rockets bolted together. Since that’s basically what it is.
The center booster is a reinforced Falcon-9, with two additional Falcon-9s as strap-on boosters. Once the Falcon Heavy lifts off, the three boosters will detach and will individually land back on Earth, ready for reassembly and reuse. This system will be capable of carrying 54,000 kilograms into low Earth orbit. In addition, SpaceX is hoping to take the technology one more step and have the upper stage return to Earth.
Imagine it. Three boosters and upper stage and payload fairing all returning to Earth and getting reused.
And waiting in the wings, of course, is SpaceX’s huge Interplanetary Transport System, announced by Elon Musk in September of 2016. The super-heavy lift vehicle will be capable of carrying 300,000 kilograms into low Earth orbit.
For comparison, the Apollo era Saturn V could carry 140,000 kg into low Earth orbit, so this thing will be much much bigger. But unlike the Saturn V, it’ll be capable of returning to Earth, and landing on its launch pad, ready for reuse.
SpaceX just crossed a milestone, but they’re not the only player in this field.
Perhaps the biggest competitor to SpaceX comes from another internet entrepreneur: Amazon’s Jeff Bezos, the 2nd richest man in the world after Bill Gates. Bezos founded his own rocket company, Blue Origin in Seattle, which had been working in relative obscurity for the last decade. But in the last few years, they demonstrated their technology for reusable rocket flight, and laid out their plans for competing with SpaceX.
In April 2015, Blue Origin launched their New Shepard rocket on a suborbital trajectory. It went up to an altitude of about 100 km, and then came back down and landed on its launch pad again. It made a second flight in November 2015, a third flight in April 2016, and a fourth flight in June 2016.
That does sound exciting, but keep in mind that reaching 100 km in altitude requires vastly less energy than what the Spacex Falcon 9 requires. Suborbital and orbital are two totally milestones. The New Shepard will be used to carry paying tourists to the edge of space, where they can float around weightlessly in the vomit of the other passengers.
But Blue Origin isn’t done. In September 2016, they announced their plans for the follow-on New Glenn rocket. And this will compete head to head with SpaceX. Scheduled to launch by 2020, like, within 3 years or so, the New Glenn will be an absolute monster, capable of carrying 45,000 kilograms of cargo into low Earth orbit. This will be comparable to SpaceX’s Falcon Heavy or NASA’s Space Launch System.
Like the Falcon 9, the New Glenn will return to its launch pad, ready for a planned reuse of 100 flights.
A decade ago, the established United Launch Alliance – a consortium of Boeing and Lockheed-Martin – was firmly in the camp of disposable launch systems, but even they’re coming around to the competition from SpaceX. In 2014, they began an alliance with Blue Origin to develop the Vulcan rocket.
The Vulcan will be more of a traditional rocket, but some of its engines will detach in mid-flight, re-enter the Earth’s atmosphere, deploy parachutes and be recaptured by helicopters as they’re returning to the Earth. Since the engines are the most expensive part of the rocket, this will provide some cost savings.
There’s another level of reusability that’s still in the realm of science fiction: single stage to orbit. That’s where a rocket blasts off, flies to space, returns to Earth, refuels and does it all over again. There are some companies working on this, but it’ll be the topic for another episode.
Now that SpaceX has successfully launched a first stage booster for the second time, this is going to become the new normal. The rocket companies are going to be fine tuning their designs, focusing on efficiency, reliability, and turnaround time.
These changes will bring down the costs of launching payloads to orbit. That’ll mean it’s possible to launch satellites that were too expensive in the past. New scientific platforms, communications systems, and even human flights become more reasonable and commonplace.
Of course, we still need to take everything with a grain of salt. Most of what I talked about is still under development. That said, SpaceX just reused a rocket. They took a rocket that already launched a satellite, and used it to launch another satellite.
It’s a pretty exciting time, and I can’t wait to see what happens next.
Now you know how I feel about this accomplishment, I’d like to hear your thoughts. Do you think we’re at the edge of a whole new era in space exploration, or is this more of the same? Let me know your thoughts in the comments.
Blue Origin successfully conducted an in-flight test of the New Shepard crew escape system on Wednesday. A live webcast featured stunning views of the crew capsule blasting away from the rocket booster 45 seconds into the flight with a two-second burn, and then parachuting safely back down to the ground. “We’re speechless right now and absolutely rightfully so,” said launch commentator Ariane Cornell.
Adding to the excitement, the rocket booster unexpectedly also survived the test, returning intact and making a successful vertical landing back at Blue Origin’s West Texas facility. So, yes, we were wrong about it ending in ‘fiery destruction.’ Blue Origin founder Jeff Bezos had said computer simulations showed a minimal chance the booster could survive the stresses of “70,000 pounds of off-axis force delivered by searing hot exhaust,” from the capsule escape motor, and then successfully return and land vertically as it’s done previously.
Bezos was pumped about the outcome, tweeting “That is one hell of a booster,” and included this Vine video of the event:
This is the fifth launch and landing of this rocket, the fourth made just this year. The successful landing of the booster means the intact rocket will find a place of honor – perhaps in a museum or even as a lawn ornament at Blue Origin, as SpaceX did.
Here’s the webcast:
This is the fifth launch and landing of this rocket, the fourth made just this year. The successful landing of the booster means the intact rocket will find a place of honor – perhaps in a museum or even as a lawn ornament at Blue Origin, as SpaceX did.
The escape system is designed to safely separate the New Shepherd crew capsule from the rocket booster in the event of an anomaly during flight, protecting a future crew. The abort system performed as expected, as about 45 seconds after liftoff, the escape motor ignited underneath the crew capsule. The motor burned for two seconds and shot the capsule up and away from the rocket booster. After a bit of tumbling – which would have given any occupants inside a fairly wild ride –the capsule’s parachutes deployed, allowing it to land safely. It will be interesting to hear followup on the tumbling from Blue Origin’s engineers, to see how unexpected that might be.
Cornel said this was a nominal test, providing an “exhilarating but safe ride.”
Once it was obvious the booster survived the blast from the escape system, it was fun and nail-biting to watch the booster reach the edge of space and then begin its descent. It used a series of braking maneuvers then just 8 minutes after launch as it approached the ground –still vertical — its BE-3 engine turned on and the landing legs deployed. The booster – looking only a little worse for wear — touched down gently.
Cornell said both the capsule and the booster will be retired, earning another turtle stencil.
Blue Origin hopes to launch paying passengers into suborbital space by 2018 and today’s successful test means the company is on track to make it so.
Today’s successful test flight won praise from many in the industry. Eric Stallmer, presdient of the Commercial Spaceflight Federation congratulated the Blue Origin team and said, “Today’s fifth successful flight proved the New Shepard’s most critical safety features, innovative escape system technologies, and overall robustness of their system. It’s an exciting time to see these fantastic technological advancements and to witness the power of commercial industry.”
The last time an in-flight escape system test for a crew capsule took place was during the Apollo program, in 1966. Now, you can watch live as Blue Origin tests the escape system for their New Shepard rocket on Wednesday, October 5, 2016 at 10:45 a.m. ET. The test was originally planned for today (Tuesday) but was postponed because of inclement weather.
You can watch live here:
As founder Jeff Bezos described the test, “Our next flight is going to be dramatic, no matter how it ends.” If all goes well, the crew capsule (empty, this time) should land rather gently. The likely end for the rocket booster, however, will be its destruction in a ball of flames.
Although the New Shepard has already launched successfully four times since November 2015, this fifth flight will test the system to protect future passengers from any anomaly during launch. Unlike the Apollo escape system that used an escape “tower” motor located on top of the capsule to ‘pull’ the crew cabin away from a failing booster, New Shepard’s escape system is mounted underneath the capsule, to ‘push’ the capsule away from a potentially exploding booster.
As the video below from Blue Origin explains, “Like the airbag in your car, this full envelope capsule escape system is always there if needed.” Bezos also described the test in an email:
About 45 seconds after liftoff at about 16,000 feet, we’ll intentionally command escape. Redundant separation systems will sever the crew capsule from the booster at the same time we ignite the escape motor. The escape motor will vector thrust to steer the capsule to the side, out of the booster’s path. The high acceleration portion of the escape lasts less than two seconds, but by then the capsule will be hundreds of feet away and diverging quickly. It will traverse twice through transonic velocities – the most difficult control region – during the acceleration burn and subsequent deceleration. The capsule will then coast, stabilized by reaction control thrusters, until it starts descending. Its three drogue parachutes will deploy near the top of its flight path, followed shortly thereafter by main parachutes.
While SpaceX successfully tested their escape system in May 2015, it wasn’t an in-flight test. The Crew Dragon spacecraft abort system was launched off a specially built platform at Cape Canaveral Air Force Station’s Space Launch Complex 40 in Florida. The engines fired for about six seconds, instantly producing about 15,000 pounds of thrust each and lifting the spacecraft out over the Atlantic Ocean and parachuting safely into the water.
Bezos said that while they’d really like to retire this New Shepard booster and put it in a museum, that’s probably not a possibility.
“It’s the first ever rocket booster to fly above the Karman line into space and then land vertically upon the Earth,” he said. “But the booster was never designed to survive an in-flight escape. The capsule escape motor will slam the booster with 70,000 pounds of off-axis force delivered by searing hot exhaust. The aerodynamic shape of the vehicle quickly changes from leading with the capsule to leading with the ring fin, and this all happens at maximum dynamic pressure.”
Monte Carlo simulations show there’s some chance the booster can survive those stresses and land vertically as it’s done previously. But probably not. There will still be propellant on board and if it lands hard, as expected, Bezos said “its impact with the desert floor will be most impressive.”
Space exploration is becoming a lucrative domain for private aerospace companies (aka. the NewSpace industry). With opportunities for launch and resupply services growing, costs dwindling, and the cancellation of the Space Shuttle Program, private companies have been stepping up in recent years to provide their own launch vehicles and services to fill the gap.
Take Jeff Bezos, for example. Back in 2000, the founder of Amazon.com created Blue Origin to fulfill his lifelong dream of colonizing space. For years, Bezos and the company he founded have been working to produce their own fleet of reusable rockets. And as of the morning of Monday, Sept. 12th, he unveiled their newest and heaviest rocket – the New Glenn.
Much like SpaceX, Blue Origin has been committed to the creation of reusable rocket technology. This was made clear with the development of the New Shepard suborbital rocket, which was unveiled in 2006. Named in honor of the first American astronaut to go into space (Alan Shepard), this rocket made its first flight in April of 2015 and has had an impressive record, nailing four out of five soft landings in the space of just over a year.
With the New Glenn – named in honor of astronaut John Glenn, the first American astronaut to orbit the Earth – the company now intends to take the next step, offering launch services beyond Low-Earth Orbit (LEO) and for crewed missions. As Bezos said during the press conference:
“New Glenn is designed to launch commercial satellites and to fly humans into space. The three-stage variant-with its high specific impulse hydrogen upper stage—is capable of flying demanding beyond-LEO missions.”
According to Bezos, Blue Origin will have both a two-stage and three-stage variant of the rocket. Whereas the two-stage will provide heavier lift capacity to LEO, the three-stage will be able to reach further, and will the company’s go-to when sending crewed missions into space. Work on the rocket began back in 2012, and the company hopes to make their first launch prior to 2020.
As Bezos said during the unveiling, this rocket carries on in the same tradition that inspired the creation of the New Shepard:
“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. Named in honor of John Glenn, the first American to orbit Earth, New Glenn is 23 feet in diameter and lifts off with 3.85 million pounds of thrust from seven BE-4 engines. Burning liquefied natural gas and liquid oxygen, these are the same BE-4 engines that will power United Launch Alliance’s new Vulcan rocket.”
The rocket will have a sea-level thrust of 1.746 million kg (3.85 million lbs), placing it ahead of the Delta IV Heavy – which has a sea-level thrust of about 900,000 kg (2 million lbs) – but behind the 2.268 million kg (5 million lbs) of the Falcon Heavy. Both variants will be powered by BE-4 engines, which are also manufactured by Blue Origin. The third-stage also employs a single vacuum-optimized BE-3 engine that burns liquid hydrogen and liquid oxygen.
However, the most interesting facet of the New Glenn is the fact that it will be reusable, with its first stage providing braking thrust and deployable legs (similar to the Falcon 9). In creating a heavy lift rocket that employs a retrievable first-stage, Blue Origin has signaled its intent to give SpaceX a run for its money when it comes to the development of reusable rocket technology.
It is also likely to raise the company’s profile, which has so far been limited to conducting sub-orbital research for NASA and dabbling in the space-tourism industry. But once the New Glenn is up and running, it is likely to begin securing contracts to provide resupply services the ISS, as well as contracts with companies and research institutions to place satellites in orbit.
According to The Verge, Bezos also hinted that his company has another project in mind – called the New Armstrong. While no details have been given just yet, the name of this rocket is a clear allusion to the Moon Landing, and hints that the company may have designs on possible moon missions in the coming decades.
This is an exciting time for the NewSpace industry. In the coming months, SpaceX is expected to conduct the first launch of the Falcon Heavy, which will be the most powerful rocket built in the US since the retirement of the Apollo program’s Saturn V launcher. And if they keep to their current schedule, Blue Origin will be following this in a few years time with the launch of the largest rocket of the post-Apollo era.
Big rockets and big lift capacities can mean only thing: big things lie ahead of us!
Blue Origin, the builder of the New Shepard re-usable rocket, has announced plans for the fourth flight of the rocket. With a recent successful launch and landing in their pocket, the company is anticipating another similar result. But this time, something will be done differently.
This time around, New Shepard will be launched and landed normally, but the crew capsule will be tested with an intentionally failed parachute. Blue Origin is promising an “exciting demonstration,” and in an email said they will be “demonstrating our ability to safely handle that failure scenario.”
Though no date has yet been set for this gimped-parachute demonstration, we are looking forward to it.
In previous tests, the crew capsule performed maneuvers that characterized its aerodynamics and reduced what are called ‘model uncertainties.’ Greater predictability is what these test flights are designed to achieve. Obviously, too many question marks are not good.
As Jeff Bezos, head of Blue Origin, said in an email, “One of the fundamental tenets of Blue Origin is that the safest vehicle is one that is robust and well understood. Each successive mission affords us the opportunity to learn and improve our vehicles and their modeling.”
The company also shared news of the construction of additional test cells at its facility in West Texas. These cells were announced in October, and now one of the cells has been commissioned. This cell “supports the development of the pre-burner start and ignition sequence timing” according to Bezos.
Bezos also touted the benefits of privately-funded endeavours, saying “…one of the many benefits of a privately funded engine development is that we can make and implement decisions quickly. We made the decision to build these two new test cells as a team in a 10 minute discussion.” He added, “Less than three weeks later we were pouring concrete and now we have an operating pressure fed test cell 7 months later.”
It’s clear that privately-funded initiatives can have more flexibility than governmental initiatives. They don’t face the same budgetary wrangling that organizations like NASA do. But, they don’t command the same resources that NASA does.
Companies like Blue Origin an SpaceX are very innovative and are leading the way in reusable rockets. If Blue Origin can make the crew capsule survivable in a failed parachute scenario, as the next test aims to do, then commercial space flight will benefit. Private trips to space, which are one of Blue Origin’s goal, will also become more and more attainable.
On Friday, January 22nd, commercial space company Blue Origin successfully launched and landed its reusable rocket, New Shepard, at their launch facility in Texas. This is the second flight for New Shepard, showing that reusable rockets are on their way to becoming the launch system of choice. New Shepard launched, travelled to apogee at 101.7 kilometres, (63.19 miles) and then descended to land safely at their site in West Texas. This is the first successful reuse of a rocket in history.
Reusable rockets are an important development for space travel. Rockets are enormously expensive, and having to trash each rocket after a single use makes commercial space flight a real challenge. Blue Origin—and other companies like SpaceX—are blazing a trail to cheaper space flight with their reusable designs. This is great, not only for all the good sciencey reasons that we love so much, but because eventually civilian space enthusiasts may be able to travel past the Karman Line without having to sell all their possessions to do so.
