Blue Origin pulls off its first unmanned test flight from a site in west Texas. The spacecraft, which reached an altitude of 58 miles, is designed to become a reusable vehicle for space tourists someday.
Blue Origin, a spacecraft startup owned by Amazon CEO Jeff Bezos, carried out an unmanned maiden test flight of its New Shepard suborbital rocket Wednesday, the company revealed early Thursday.
A dramatic video posted on the Blue Origin website showed the squat rocket being erected on a launch platform at the company’s west Texas development facility followed by a brief countdown — with Bezos looking on — then a smooth liftoff and a vertical climb to an altitude of 58 miles.
At that point, the dummy crew capsule separated from its booster and completed a parachute descent to Earth.
“Our 110,000 pound thrust liquid hydrogen, liquid oxygen BE-3 engine worked flawlessly, powering New Shepard through Mach 3 to its planned test altitude of 307,000 feet,” Bezos said in a blog post. “The in-space separation of the crew capsule from the propulsion module was perfect. Any astronauts on board would have had a very nice journey into space and a smooth return.”
However, the New Shepard is intended to be a fully reusable suborbital spacecraft with the propulsion module flying itself to a vertical, rocket-powered landing after separation from the crew capsule. That part of the test flight Wednesday was not successful, and the video did not include any shots of its descent.
“One of our goals is reusability, and unfortunately we didn’t get to recover the propulsion module because we lost pressure in our hydraulic system on descent,” Bezos wrote. “Fortunately, we’ve already been in work for some time on an improved hydraulic system. Also, assembly of propulsion module serial numbers 2 and 3 is already underway — we’ll be ready to fly again soon.”
Blue Origin is one of several space-focused companies owned by tech industry leaders who have a keen interest in either tourism or cargo delivery. Blue Origin wants to send tourists on brief trips into space, as does Richard Branson’s Virgin Galactic. Meanwhile, Elon Musk’s SpaceX is more focused on cargo trips to the International Space Station and possibly colonizing Mars. These private companies have celebrated small successes but have discovered that rocketry is no easy feat, with repeated crash landings and even a pilot’s death last fall.
The New Shepard vehicle is built around the company’s hydrogen-fueled BE-3 engine, which can be throttled through a wide range of power settings. The booster is designed to propel a crew/cargo capsule to altitudes above 62 miles, the generally accepted boundary of space. The capsule then separates for four to five minutes of weightlessness before falling back into the discernible atmosphere for a parachute descent.
The booster, meanwhile, is designed to carry out an autonomous powered descent, using the variable-throttle BE-3 engine to fly back to a vertical touchdown for refurbishment and reuse. After an extensive series of test flights, Blue Origin hopes to begin launching people, payloads or both as a commercial endeavor
“New Shepard is designed to carry three or more astronauts up to sub-orbital space,” Blue Origin President Rob Meyerson told reporters earlier this month. “We say ‘three or more’ because there are combinations of astronauts and science payloads. We believe the science payload market is going to be a big one, as well.”
“We continue to be big fans of the vertical takeoff, vertical landing architecture,” Bezos said. “We chose VTVL because it’s scalable to very large size. We’re already designing New Shepard’s sibling, her Very Big Brother — an orbital launch vehicle that is many times New Shepard’s size and is powered by our 550,000-pound thrust liquefied natural gas, liquid oxygen BE-4 engine.”
The BE-4 has been selected by United Launch Alliance, a partnership between Boeing and Lockheed Martin, to power the company’s new Vulcan rocket, the successor to the Atlas 5 and Delta 4 families of boosters.
