Giant Rotating Arm to Launch Satellites, First Batch Set for Liftoff

Space companies are investing millions in the search for newer, more cost-effective methods to launch satellites. One company, however, is taking a radically different approach by planning to catapult satellites into orbit—without the need for rockets or fuel.

SpinLaunch, a California-based company, has gained attention for its groundbreaking satellite launch system powered entirely by electricity. Their concept involves a massive rotating arm that will hurl satellites into low Earth orbit, eliminating the need for traditional rockets.

The company has already conducted multiple successful test launches and is targeting 2026 for a full satellite deployment.

“This isn’t a rocket, and the fact that we’ve managed to conduct so many successful tests within just 11 months really showcases the strength of our technology,” said Jonathan Yaney, SpinLaunch’s founder and CEO, in 2022.

The technology relies on kinetic energy, an ancient principle used in medieval trebuchets and siege weapons to launch heavy objects over great distances. What sets SpinLaunch apart is its use of advanced materials and miniaturized electronics, including high-strength carbon fiber and modern electronic systems, which make the kinetic launch system viable in the space industry.

According to the company’s website, “Modern electronics, materials, and simulation tools make it possible to adapt satellites for the kinetic launch environment with relative ease.”

This catapult-like method offers significant environmental benefits, eliminating the need for rocket fuel, which is typically consumed in large quantities during traditional satellite launches. Rocket launches also contribute to ozone layer depletion, an issue that SpinLaunch’s technology aims to address.

A video of a test launch in New Mexico resembles a NASA mission control environment, with engineers closely monitoring as a satellite is flung from the launch barrel in a blink-and-you’ll-miss-it moment.

Despite the promise of the technology, there are challenges to overcome, such as handling extreme conditions, including the vacuum of space and the rapid acceleration during launch.

Founded in 2014, SpinLaunch has collaborated with NASA, Airbus, and Cornell University. The company is now focused on developing a coastal orbital launch site, further advancing its vision for rocket-free satellite launches.
