The secret to protecting next-gen spacecraft might be eggshells
Researchers have developed a new aluminum material inspired by the structural properties of eggshells to protect spacecraft from orbital debris. The design utilizes ovoid geometry and water-filled arrays to improve impact resistance against high-velocity fragments.
Why it matters
As space debris becomes a greater threat to satellite constellations and spacecraft, biomimetic materials offer a promising solution for enhanced structural durability.

The shuttle program ended in 2011, but the space debris problem has only intensified as we launch more and more satellite constellations, telescopes, and spacecraft into orbit. That’s why Chinese scientists have devised a new aluminum material inspired by eggshells that they believe could offer enhanced protection against debris fragments, according to a new paper published in the Journal of Applied Physics.
