the.com/sample return capsule

means A small, heavily shielded spacecraft module designed to carry material collected in space (or on another world) safely back through Earth's atmosphere to the ground.

from A purely descriptive, modern engineering term rather than an old word with a buried story — it stitches together 'sample' (from Old French 'essample,' a thing taken as representative of a whole, ultimately from Latin 'exemplum') and 'capsule' (from Latin 'capsula,' a little box or case, diminutive of 'capsa,' chest). The phrase itself emerged with the space age, as missions like Stardust and Hayabusa needed a plain name for the sturdy little box built to survive reentry and hand over its precious cargo of dust, rock, or gas intact.
