Small-Body Targets of Spacecraft Missions

Over the years, NASA and other space agencies have targeted asteroids and comets in their spacecraft missions. Some missions were designed specifically to learn more about physical characteristics of asteroids and comets while others were able to view asteroids on their way to other planetary destinations (such as JPL’s Galileo mission).

The following table shows small-bodies that have been, or will be, the target of selected spacecraft missions. Each row represents a target and its corresponding mission. Upcoming missions are shown with a palegreen background, current missions are shown with a lightyellow background, and past missions are shown with a lightgray background.

The table is sorted, by default, in reverse chronological order by launch date. Small-bodies that are targets of more than one mission have separate rows for each mission. Each small-body is hyperlinked to its SBDB Lookup page and mission names are hyperlinked to their mission web-page (where available).
