Slinging rockets into space
Founded in 2014, the SpinLaunch company has developed an architecture to
accelerate a small rocket to hypersonic speeds using a ground-based system
that exploits rotational energy. The rocket will be launched into the blue without
utilizing its onboard chemical propellant until the last push into orbit.

L

ast summer, the SpinLaunch space company set up shop in Long
Beach, California, around the
corner from Virgin Orbit in
the industrial neighbourhood.
SpinLaunch is reviving the decades-old idea to use giant mechanical slings to launch rockets
into space. The man behind this
bold plan is entrepreneur Jonathan Yaney who, for years, was
running SpinLaunch from an
old microprocessor plant in Silicon Valley. Now his company is
ready to open a plant to assemble rockets and send them into
space.
Prioritizing mechanical
acceleration
The SpinLaunch concept hinges
on a vacuum-sealed centrifuge
large enough to hold a football
field. The centrifuge will spin

a rocket around in circles for
about an hour while its speed
accelerates gradually to more
than 5,000 mph (8,000 km/h).
The vehicle and its payload
(a maximum 200 pounds, or
about 91 kg, of satellite) will
be subjected to forces up to ten
thousand times stronger than
gravity. Once the rocket reaches launch speed, the centrifuge
releases it, sending it flying into
the stratosphere. From there,
the rocket fires its engine to put

itself into orbit.
SpinLaunch is making use of
technology and components
that already exist in the oil/
gas, mining and wind-energy
industries to build an innovative mass-acceleration system.
The mass can reach very high
launch speeds without requiring a lot of power or any heavy
infrastructure. Once it is out
of the atmosphere, a relatively
small, inexpensive rocket made
of carbon is used to provide the

final thrust needed to enter orbit. Because most of the power
required to reach orbit comes
from ground-based electricity
instead of from the rocket's onboard propulsion fuel, the total
cost of launching is reduced by
at least an order of magnitude
compared to current launch systems.
SpinLaunch reckons that the
lower costs will make space
much more accessible to a broad
range of customers. According

SpinLaunch's vacuum-sealed centrifuge will accelerate a rocket to more than 5,000 miles per hour (©Spinlaunch)
