Missions to Comets: Stardust and Deep Impact | NASA Planetary Sciences
Explore the exciting discoveries from two NASA missions to study comets, Stardust and Deep Impact, which collected valuable data about the nature of comets. The Stardust spacecraft was designed to capture dust particles from comet Wild 2 and deliver them to Earth for analysis. The Deep Impact mission propelled a small spacecraft into comet Tempel 1 while multiple space telescopes observed the event; the data revealed valuable information about the composition and origin of comets.
