BlueOrigin conducted the 8th launch of its
New Shepard sub-orbital rocket and crew capsule today out in Texas , and things couldn’t have gone better
for the growing space tourism company. The rocket ascended into a cloudless
sky, reaching a max velocity of about 2,200 MPH, and delivered its capsule to
the edge of space, where its occupant, “Mannequin Skywalker,” will have had a
lovely view of the Earth.
New Shepard isn’t
meant to deliver things into orbit, of course; Blue Origin has a different
purpose and technology from the likes of SpaceX, focusing on giving people a
quick, safe lift into space followed by a period of weightlessness and a
pleasant descent.
That’s
what was demonstrated today, and you can watch the whole thing live in the
video below — the pre-launch coverage starts about half an
hour in, and liftoff is at the 1h10m mark.
Everything went
smoothly from liftoff to touchdown. I love watching the altitude graph filling
in slowly at first, then blasting upward as the rocket gradually accelerates.
After main-engine cutoff, which occurs just after crossing the Karmann Line,
which indicates you’ve entered space, and anyone inside would experience
weightlessness for about a minute and a half as the capsule slows down. Apogee
for this flight was 347,000 feet, or about 106,000 meters.
While Mannequin
Skywalker was enjoying microgravity, the booster was returning to Earth at high
speed — over 2,600 MPH. The drag brake deploys around 100,000 feet up, reducing
speed to a more manageable 370 MPH before the booster re-ignites at 2,500 feet
and brings itself down to a hover landing.
This is one of the
most obvious differences to a viewer between New Shepard’s booster and the
Falcon 9s; New Shepard has more control over its thrust, allowing for a highly
controlled landing where it could even float for a bit if necessary. The larger
Falcon 9 has to land using much more powerful thrust, meaning if they aren’t
careful, they might just take off again. It’s kind of like the difference
between having to let up on the gas to ease into a parking spot, and having to
pull the e-brake at precisely the right moment.
Meanwhile the capsule,
with its higher apogee and greater drag, has been falling down this whole time,
waiting for the right time to deploy its parachutes. It didn’t happen until
below the 7,000-foot mark, making me sweat a bit. It wouldn’t be a good look to
have your crew capsule impact at 240 MPH.
The commentator describes the
capsule touchdown a minute or two later as a “beautiful soft landing,” though
honestly it looks like it would give anyone inside something of a jolt. Let’s
hope the seats are comfortable in that thing.
