A giant slingshot might sound like something out of a science fair or a medieval battle—but one California startup is turning this idea into a revolutionary way to launch satellites. This system doesn’t rely on fire or flame. Instead, it uses electricity and motion to hurl satellites into space, all while promising to cut down on cost and pollution.
The company behind this innovation is SpinLaunch, and its unusual method is starting to turn heads—not just in the aerospace world, but even among fans of pumpkin-launching competitions.
Replacing Fire with Force
SpinLaunch skips the traditional use of rocket fuel. Instead, it relies on a rotating arm, spinning inside a vacuum chamber, to fling satellites into low Earth orbit. This purely electric approach is designed to reduce the environmental toll of launches while slashing the price tag.
“This is not a rocket,” said Jonathan Yaney, SpinLaunch’s founder and CEO. “And clearly our ability to perform in just 11 months this many tests and have them all function as planned really is a testament to the nature of our technology.” He spoke after the company’s 10th successful test flight.
The goal is to launch satellites into orbits below 600 miles by the year 2026. If it works, the impact could ripple across the space industry.
A Fresh Twist on an Ancient Concept
While SpinLaunch’s system looks futuristic, the science behind it is rooted in history. Long before rockets existed, siege weapons like trebuchets used similar physics to hurl objects. By converting stored energy into motion, they launched stones and other heavy items over castle walls.

Modern pumpkin-launching events, known as Punkin Chunkin contests, do the same—but with fruit. These events, popular among physics enthusiasts, showcase how potential and kinetic energy work together. Some fans now wonder: how many pumpkins could be launched into orbit using SpinLaunch’s tech?
Of course, it takes more than an old idea to reach space. It takes powerful materials and precise engineering.
High-strength carbon fiber allows the launch system to stay light but sturdy. Shrinking electronics means the payloads—small satellites—can better survive the high-speed journey. SpinLaunch says, “Modern electronics, materials, and simulation tools allow for satellites to be adapted to the kinetic launch environment with relative ease.”
That’s no small feat. The satellite must endure sudden acceleration and the vacuum of space, which can destroy delicate systems not built to handle such extremes.
Tested Under Pressure
At the company’s test site in New Mexico, SpinLaunch has run a series of successful demonstrations. One launch video shows a fast-paced, high-tech operation. Engineers watch closely as a sleek capsule vanishes from the chamber in a blink. It moves so fast, the human eye almost can’t keep up.
Founded in 2014, SpinLaunch has attracted support from big names. Its backers and partners include NASA, Airbus, and Cornell University. Their equipment has been used in testing, helping confirm the system’s strength and precision.
The launch mechanism has already handled forces as strong as 10,000 Gs—10,000 times the pull of Earth’s gravity. That’s more than enough to challenge the limits of modern technology. So far, the hardware has held up.
Better for the Earth
Traditional rockets rely on vast amounts of fuel. For instance, SpaceX’s Falcon 9 rocket used more than 900,000 pounds of propellant per launch as of 2016. Even with improvements since then, that amount of fuel remains high—and so do the risks to Earth’s atmosphere.
Rocket exhaust releases harmful chemicals that damage the ozone layer. This protective shield blocks dangerous radiation from the sun. Any method that reduces pollution during launches helps preserve it.
Because SpinLaunch uses electric power to boost satellites, it avoids fuel-based emissions during liftoff. That makes it a cleaner option from the start.
Yaney believes the system will soon move beyond tests. A coastal orbital launch site is already in development. That site will help prove the technology can work at full scale. “It has proven that it’s a system that is repeatedly reliable,” he said.
A Global Push for Smarter Launches
SpinLaunch isn’t the only group rethinking how we get to space. In Singapore, another startup is working on a similar path. Equatorial Space Systems designs modular launch vehicles for small satellites, focusing on low cost and sustainability.
Founder and CEO Simon Gwozdz said, “The total addressable market for suborbital launch from our research can be as high as USD 150 million a year.”
Their shared focus on safety, affordability, and the environment reflects a growing shift in space science. Instead of relying on massive rockets and explosive fuels, the future may lie in smaller, smarter, and cleaner tools.
As more companies take part in reshaping the space launch industry, ideas that once seemed impossible—like flinging satellites into orbit without fuel—are becoming real. SpinLaunch’s system brings ancient physics into the modern age, backed by cutting-edge materials and engineering.
What once powered medieval war machines and pumpkin contests might soon be the force behind global communications, climate monitoring, and deep space discovery.
