Sample-return mission

A sample return capsule is a specialized, unmanned spacecraft designed to collect and return samples from distant celestial bodies back to Earth for detailed analysis. These capsules are integral to planetary exploration missions, enabling scientists to study extraterrestrial materials in terrestrial laboratories with advanced equipment. The design typically includes a heat shield to withstand atmospheric re-entry, a protective shell to safeguard the samples, and a parachute system to ensure a safe landing. Notable examples include the Stardust mission, which returned particles from a comet, and the Hayabusa missions, which retrieved samples from asteroids. In Hebrew, a sample return capsule is referred to as כדור חוזר דגימות. Similar terms in other languages include Kapsel zur Rückführung von Proben in German, capsule de retour d'échantillons in French, and capsula de retorno de muestras in Spanish. These missions provide invaluable insights into the composition and origin of celestial bodies, contributing significantly to our understanding of the solar system and beyond.
