, and long-wave infrared imager, the telescope tracks man-made objects in deep space and performs space object identification data collection.

AEOS is equipped with an adaptive optics system, the heart of which is a 941-actuator deformable mirror that can change its shape to remove the atmosphere's distorting effects. Scientists are expected to get near diffraction-limited images of space objects.
