Part 3/9:
The investigation started with the identification of unique features within the blue and yellow areas. Some of the spots exhibited a crystalline morphology indicative of a possible rust formation, while others hinted at the presence of carbonaceous materials. Through elemental analysis using Energy Dispersive Spectroscopy (EDS), Bob determined the presence of key elements such as iron, aluminum, sulfur, and nickel, along with indications of other materials likely infused within the structures detected.
