The opportunities and problems of a spacecraft mission that would land on a comet nucleus, take samples, and return them in a suitably refrigerated state for study in terrestrial laboratories are discussed. These studies would greatly advance planetary science and astrophysics: the former by providing detailed information about pristine planetary material and planet-forming processes in the outer solar system; the latter by permitting the direct study of interstellar grains, individually and in great number. Laboratory techniques to handle and analyze fragile samples from the nucleus must be developed. Orbits of over 40 prospective target comets are listed. Spacecraft design and operation alternatives are summarized.
