As part of the upcoming AMADEE-27 Mars analog mission in Portugal, our team is hard at work on the \u201cCaillou\u201d project. Our goal is to develop a functional prototype of a Synthetic Raman Spectrometer, a payload designed to be integrated onto a robotic exploration platform to simulate the geological search for life on Mars.<\/strong><\/p>\n\n\n\n


Raman spectroscopy is a powerful, non-destructive tool used to identify minerals and potential biomarkers by observing how light scatters when it hits molecules. However, testing the operational workflows for such an instrument in the field can be difficult without expensive hardware. Our project aims to bridge the gap between computational simulations and real-world data acquisition. Instead of performing a real chemical analysis, our prototype acquires target information and provides physically plausible synthetic spectra from a pre-defined library to help mission operators practice scientific decision-making.

The design process began with a functional analysis to ensure the prototype mimics the behavior of a space-grade instrument while remaining a versatile guest-payload for various rovers. We identified two primary functions (FPs) that drive our design:<\/p>\n\n\n\n
