Analyzing samples from a planet, moon, or asteroid helps scientists learn about its chemistry, geologic history, and potential to support past or present life. Nearly every NASA surface mission collects samples. In this video from "Design Squad Nation," students design and build coring devices that can poke into a potato "asteroid" and extract a core sample. The students use the engineering design process, apply a variety of science concepts, and learn about NASA's exploration of the solar system. Part of the "Design Squad Nation" series.
