EMIT Instrument's First Light

This official NASA scientific visualization presents one of the first observations collected by the Earth Surface Mineral Dust Source Investigation (EMIT) after its installation aboard the International Space Station. The false-color map reveals the distribution of key minerals across part of the Sahara Desert in southwestern Libya.

Blue indicates kaolinite, yellow represents goethite, and red identifies hematite. These minerals influence how airborne desert dust absorbs and reflects sunlight, making EMIT's observations essential for improving climate models and understanding the environmental impact of mineral dust worldwide.
