What crucial device on a lander determines elemental makeup by heating samples?

Answer

Instrument designed for in situ chemical analysis

Landers are focused on surface and near-surface analysis to understand a world's geology and environment thoroughly. A particularly crucial component for determining the fundamental chemical makeup of rocks and soil is the instrument dedicated to in situ chemical analysis. This typically involves sophisticated mechanisms, such as onboard ovens, which heat collected samples to high temperatures, allowing the resulting released gases or residues to be analyzed by spectrometers to determine the precise elemental composition.
