According to, “This Company Built a Gigantic Centrifuge to Fling Rockets Into Space“, an article written by Courtney Linder and published by Popular Mechanics, SpinLaunch, a newcomer to the pursuit of space exploration, plans to enter Earth’s orbit through the use of a unique launch system.
In describing the procedure for takeoff, Linder states that “a centrifuge the size of a football will spin a rocket around in circles for about an hour until its speed eventually exceeds 5,000 miles per hour. At that point, the rocket and its payload will feel forces 10,000 times stronger than gravity. When the centrifuge finally releases the rocket at launch speed, it should, practically speaking, fly through the stratosphere until it fires its engines at the periphery of our atmosphere” (Linder).
SpinLaunch claims that this action will account for a large portion of the distance needed to enter orbit, and that fuel-based boosters will only be used in a small portion of the rocket’s flight (SpinLaunch via Wired and Popular Mechanics)(Oberhaus)(Linder).
While the rocket and payload will undergo immense stress, the company has reportedly completed successful tests on cargo within their smaller-scale, test centrifuge. That being said, this test model does not induce the same increased force of gravity as SpinLaunch’s ideal centrifuge (SpinLaunch via Wired and Popular Mechanics)(Oberhaus)(Linder).
The centrifuge holds promise, and “in June, SpinLaunch signed a responsive launch prototype contract with the Department of Defense to build out its kinetic energy-based launch system that will provide a lower-cost option for the ever-growing satellite industry” according to Linder (Linder).
In my opinion, I believe that this technology has the potential to revolutionize space travel as it is known today. The development of a reusable launch system and minimal use of rocket propulsion of fuel will most likely reduce the cost of launching a satellite into orbit immensely. Hopefully, this reduced price tag will aid in human research efforts in Earth’s immediate orbit and bolster mankind’s understanding of space itself.
