A promising material for hypervelocity impact shields in spacecraft and satellites has been found in lightweight microcellular SiOC foams. The foam stops the projectile and the debris from the impacted bumper facesheet within a few millimeters (see Figure for a cross‐section of the crater) at speeds up to 5.1 km s –1 . The impacted SiOC ceramic did not react with incoming debris, and no phase transformation or compositional change was observed.
