SpinLaunch has proven that satellites can survive a shot from a “space cannon”. A California startup that develops a unique launch system has tested launching a small satellite under extreme gravitational forces to show it can withstand acceleration up to 10,000G.
The successful test marks a major milestone for SpinLaunch, which is seeking to develop a centrifugal launch system capable of delivering small satellites into low Earth orbit. During a demonstration in the laboratory, the company first tested a 1U CubeSat prototype with reinforced housing components.
“For potential customers, this testing has become an engineering case study that helps develop satellites for our system,” explained Sev Sandomirsky, director of satellite programs at SpinLaunch.
The testing was done in collaboration with Portland State University’s CubeSat program. SpinLaunch engineers made some minor changes to the satellite’s design: modifying the batteries for better stability and replacing Aluminum 6061 with a stronger 7075. They also reinforced parts of the circuit boards to minimize stress on sensitive elements. These changes made the satellite compatible with SpinLaunch launch conditions, Sandomirsky said.
Surprisingly, the 1U CubeSat needed only minimal modifications to withstand the extreme loads. “Many modern satellites are already capable of withstanding such conditions,” Sandomirsky noted. The Company recognizes that not all components are suitable for these conditions. However, those that fit their launch system can successfully survive launch and be used in Earth orbit.
About SpinLaunch Startup
SpinLaunch, founded in 2014, is developing an eco-friendly and affordable way to launch into space. Its concept is based on a kinetic system that uses a giant centrifuge to catapult cargo into the stratosphere. Next, propulsion completes the journey. This technology can reduce launch costs by 10 times and cut fuel use by 70% compared to traditional rockets.
SpinLaunch is slowly realizing its ambitious plans. In 2021, the company successfully tested the A-33 suborbital booster in New Mexico, lifting the projectile 7.6 kilometers high. In 2022, SpinLaunch launched demonstration payloads for NASA, Airbus, Cornell University and Outpost Space. CEO David Wrenn said their system had the potential to reduce costs, increase launch frequency and open up new opportunities for satellite networks.
SpinLaunch recently raised $11.5 million to develop the technology and further testing. This will help the company move even closer to revolutionizing the space industry.
