On Sunday, June 19, 2016 at approximately 14:15 UTC (10:15 a.m. Eastern time), the private rocket company Blue Origin plans to launch their New Shepard rocket for the fourth time. As with the three previous tests, it’ll launch straight up, deploy the crew capsule, and then come back down vertically. The crew capsule will come back much more slowly, using parachutes to descend gently (and a retrothrust system to make sure the landing isn’t too rough).
Except this time, the company has rigged it so that only two of the three parachutes will open.
This test is being done on purpose to make sure they can still safely land in the event of single parachute failure. As Blue Origin CEO Jeff Bezos said, “Works on paper, and this test is designed to validate that.”
This should be an exciting test. In a very different move for the company, they have announced they’ll be streaming the event live on their website (it starts at 13:45 UTC, a half hour before the launch). I find that very interesting; in general the company has not done that; they release video after the flights, and rarely even announce when the launch tests will be. I wouldn’t say they’re secretive, but they tend not to actively seek publicity.
I have to wonder if the live coverage of SpaceX launches is behind this decision. Obviously, SpaceX has captured the lion’s share of the public’s attention when it comes to rocket launches. SpaceX has carefully cultivated an excellent public outreach effort, and the result is that their launches are watched live by a lot of folks. I imagine Blue Origin wants a piece of that.
They deserve it. New Shepard (named after astronaut Alan Shepard, the first American in space) has launched successfully three times, and each flight has tested different aspects of the process, including a quick restart of the engine only a kilometer above the ground before landing. It’s actually pretty amazing.
What SpaceX is doing and what Blue Origin is doing are, at the moment, very different. SpaceX is launching a very large rocket into orbit, meaning it has to go sideways (usually to the east) very rapidly to go around the Earth. Blue Origin’s flights are suborbital; the rocket goes essentially straight up, past the arbitrary but generally agreed-upon 100-km altitude marking the beginning of space (at that height, there’s almost no air and no drag on the rocket). That’s far easier than going into orbit.
But not easy. Going up that high, releasing a capsule, having that land safely, and landing the rocket itself back down vertically on its tail is incredibly hard. Blue Origin has shown they’re getting the hang of it, though.
And while there’s a good market for suborbital flights (even a few minutes of free fall can be very useful scientifically), the plan is to use the knowledge gained to create a more powerful rocket capable of orbital flight. This is how SpaceX did it with the Falcon 1 rocket that led to the Falcon 9, and Blue Origin has similar ideas. Their BE-4 engine, currently being tested, should have enough oomph to do this. United Launch Alliance, which makes the Atlas and Delta rockets, has partnered with Blue Origin to develop this engine for use with their next generation Vulcan rocket. That’s being created as a competitor for SpaceX’s Falcon series, and I’ll be very interested indeed to see how this goes.
I’ll be getting up early Sunday morning to watch this fourth New Shepard test flight, and live tweeting it, too. Rocket launches are fun and exciting, and these tests are the first steps toward a bigger and better arena for commercial spaceflight. I have a lot of hope for this new chapter in space exploration. A lot, and I think it’s been earned.
There’s an (apocryphal) curse: “May you live in exciting times.” I don’t think it’s a curse. I think it’s the best time to be alive.
