The Stardust Mission: Collecting Comet Dust in Space

The video discusses the preservation of comets and their origins in the Kuiper Belt. It details NASA's Stardust mission, which aimed to collect comet dust using a spacecraft launched in 1999. The mission faced challenges due to the high speed of comets, requiring innovative solutions like using Earth's gravity for a speed boost. The spacecraft used aerogel to safely capture dust particles. The mission also collected interstellar dust, providing insights into space. Discoveries from the mission include potential organic compounds, suggesting comets may have contributed to life on Earth.
