Drill

Definition

In the context of planetary missions, a drill is a specialized tool designed to penetrate the surface of celestial bodies to collect subsurface samples for analysis. Drills are crucial for understanding the geological history and composition of planets and moons, enabling scientists to uncover hidden resources and processes that shaped these bodies over time.

5 Must Know Facts For Your Next Test

1. Drilling technology has evolved significantly, with modern drills being equipped with advanced sensors to provide real-time data on subsurface conditions.
2. NASA's Mars missions have employed drills to extract soil and rock samples, allowing scientists to study the planet's potential for past life.
3. The ability to drill deep into the surface can reveal layers of history that are otherwise hidden, including ice deposits or ancient volcanic activity.
4. Drills are essential for missions targeting icy bodies, like Europa or Enceladus, where subsurface oceans might be accessed for astrobiological studies.
