All day
All times

Comets and asteroids preserve the least-altered materials remaining from the birth of the Solar System. However, the few visited by spacecraft are diverse in composition, and touring enough of these small bodies for a representative sample would be costly and time-consuming. A team of us is therefore developing a proposal for a mission to measure the makeup of large numbers of comets and asteroids via the dust they shed into the Zodiacal Cloud.
