Lunar and Martian Missions:
* Tongs and scoops: These simple tools were used on early missions like Apollo to pick up rocks and soil.
* Core tubes: These hollow tubes were used to extract core samples of lunar regolith.
* Rock hammers: Used to break off pieces of larger rocks for analysis.
* Sample bags and containers: Used to store collected samples for return to Earth.
Current and Future Missions:
* Robotic arms and drilling equipment: Missions like Curiosity and Perseverance utilize robotic arms to collect samples and drill into the ground.
* Sample tubes and caches: Samples are collected and stored in specialized tubes and caches for analysis by rovers or future missions.
* Specialized instruments: Rovers like Curiosity are equipped with instruments that can analyze samples in situ, providing immediate data on the composition and history of the rock.
Specific Examples:
* Apollo missions: Astronauts used geological hammers, tongs, scoops, and core tubes to collect samples on the Moon.
* Mars rover Curiosity: The rover uses its robotic arm to collect samples and analyzes them with instruments like ChemCam and SAM.
* Mars rover Perseverance: This rover uses a drill to collect core samples, which are stored in tubes for future return to Earth.
The specific tools and techniques used to collect geological samples are chosen based on the mission objectives, the nature of the surface being explored, and the limitations of the spacecraft and the environment.
