Reflected light images like these serve as a scientist’s road map, helping them find minerals of interest to analyze by different instruments.Figure AFigure A is the same image with annotations showing minerals like iron-titanium oxides (brighter grains) and pyroxene (medium gray), both of which tell a story about the formation of Mars’ crust and mantle. Shocked plagioclase (darker gray) is created by extreme pressures during impacts, including the one that sent Teghaza 001 flying through space to Earth. The alteration represents fine grain carbonate, sulfate and clay minerals formed on Earth.Keep ExploringDiscover More Topics From PhotojournalPhotojournalSearch PhotojournalPhotojournal’s Latest ContentFeedback
