SpinLaunch, the startup currently developing a suborbital accelerator, debuts the world’s first ruggedized satellite in partnership with Portland State University. This is the first known satellite capable withstanding 10,000Gs.
To accomplish this, the team first had to rotate the battery cells so they acted as pillars, thus giving them the ability to support their own weight along the long axis. The satellite’s Aluminum 6061 material was also upgraded to Aluminum 7075, which has more strength, and then reinforced larger parts of the circuit boards to minimize stress on sensitive components.

It’s presumably very helpful that the G-loading is both steady/gradual (rather than a vibration that could build up resonance or cause fatigue) and that it only goes in one direction for which the satellite can be preferentially hardened. Still, pretty impressive!,” said one commenter.
