Bold claim: a feather-thin material from a California startup is quietly reshaping how we protect spacecraft hardware from brutal launches. MetaSeismic’s approach, born from AI-driven metamaterial design, wasn’t originally aimed at space missions. Yet recent tests at NASA’s Marshall Space Flight Center demonstrate its potential to shield a critical battery during a simulated launch, reducing harmful vibrations dramatically.
NASA’s take is striking: the damping layer is smaller and lighter than many traditional solutions, yet it can be precisely tuned to the specific vibration environment faced by different hardware—whether it’s avionics, a battery, or another sensitive component. In a Space Act Agreement test, a slim MetaSeismic layer cut the vibration force on a launch vehicle battery from 20 g’s down to about 0.5 g across three axes, spanning frequencies from 0 to 2,000 hertz. This performance comes from a material that is both exceptionally thin and lightweight, according to MetaSeismic’s claims.
The feedback from the testing team underscores the breakthrough: broad-spectrum damping across a wide frequency range is a game changer for safeguarding delicate payloads.
MetaSeismic’s founder, Noemi Bonessio, a scientist and entrepreneur with a PhD from the University of Rome and postdoc experience at UC San Diego, explains that the idea emerged from work on protecting electronics from earthquake shocks. The Berkeley-area startup continues to pursue the original earthquake-shock protection mission while expanding the platform to new arenas. Bonessio notes that the technology is now positioned to tackle a variety of applications—from quantum computing systems to space hardware and robotics that require precise vibration control during semiconductor manufacturing.
NASA’s collaboration dates to 2022, driven by a common challenge: extreme dynamic forces can jeopardize hardware without adding heft. As James “JR” Booker of NASA Marshall explains, whether facing an 8.5 magnitude earthquake or 20 g’s during launch, the goal is to mitigate intense motion without increasing weight or bulk.
Vibration and shock are constants in spaceflight—during launch, stage separation, descent, and landing, stresses accumulate across a product’s lifecycle. The MetaSeismic platform wasn’t originally designed for space use, but the NASA partnership is described by Bonessio as both a dream and an honor.
