CTX (Context Camera)

A CTX, or Context Camera, is a high-resolution camera used on spacecraft like Mars orbiters to capture detailed images of planetary surfaces. Its primary function is to provide context for other instruments by taking wide-area, detailed photographs that help scientists understand the geography and location of specific features. This allows for better navigation, planning of scientific investigations, and targeting of other instruments. Think of it as a sophisticated aerial photo camera that helps map and study planets from above, offering valuable visual information to guide further exploration and analysis.
