The secret to protecting next-gen spacecraft might be eggshells
Chinese scientists developed an eggshell-inspired aluminum material for enhanced space debris protection, published in the Journal of Applied Physics Water-filled eggshell-shaped aluminum structures reduced projectile velocity by nearly 65%, outperforming plain aluminum plates (51% reduction) The design draws on eggshell biomechanics: upright orientation with narrow tip contacting the top plate proved most effective Water filling dissipates impact energy by sloshing, preventing impact wave propa
