How is stardust collected?

Answer 1

Stardust is collected using specialized instruments designed to capture tiny particles from space. For example, NASA's Stardust mission collected particles from the comet Wild 2 by flying through its coma and capturing dust grains on aerogel, a lightweight material. Once collected, these particles are returned to Earth for analysis, allowing scientists to study the composition of comets and the early solar system. The process requires precise navigation and timing to ensure successful collection during the spacecraft's flyby.
