Spacecraft Protection And Hypervelocity Impacts
The consequences of meteoroid and debris impacts on spacecraft can range from small surface pits due to micrometre-size impactors and clear-hole penetrations for millimetreÂ-size objects, to mission-Âcritical damage for projectiles larger than 1 cm. Any impact of a 10 cm catalogue object on a spacecraft or orbital stage will most likely entail a catastrophic disintegration … [Read more...] about Spacecraft Protection And Hypervelocity Impacts
