Quantum Dot Spectrometer in Development for Use in Space

A prototype of an imaging spectrometer based on quantum-dot technology could miniaturize and potentially revolutionize space-based spectrometers, particularly those used on uninhabited aerial vehicles and small satellites. The research is a collaborative effort between NASA’s Goddard Space Flight Center and the Massachusetts Institute of Technology (MIT). NASA researchers are currently working to develop, qualify through thermal vacuum and vibration tests, and demonstrate a 20 × 20 quantum-dot array that is sensitive to visible wavelengths needed to image the sun and the aurora.
