What is the primary purpose of collecting and sealing samples of rock and soil?

Answer

To analyze the samples in advanced terrestrial laboratories

While the rover conducts valuable in situ measurements, it cannot replicate the level of detail and sophistication found in Earth-based laboratories. By sealing and caching rock and soil samples, scientists prepare them for a future mission to bring the material back to Earth. Once here, these samples can be examined using the most advanced microscopes and analyzers, providing a definitive, multi-layered investigation that is currently impossible to perform on Mars.
