The STARDUST mission collected cometary coma and interstellar dust samples using silica aerogel. These primitive materials were returned to Earth for laboratory analysis to understand their composition.

Area of Science:

  • Planetary Science
  • Cosmochemistry
  • Astrophysics

Background:

  • Primitive solar system materials offer insights into early planetary formation.
  • Cometary dust and interstellar dust are key components of these primitive materials.

Purpose of the Study:

  • To collect and return samples of cometary coma and interstellar dust to Earth.
  • To analyze the composition and properties of these extraterrestrial samples.

Main Methods:

  • The STARDUST mission spacecraft captured dust particles (1-100 micrometers) using aerogel.
  • Samples were collected during a flyby of Comet Wild 2.
  • Returned samples undergo laboratory investigation.

Main Results:
