DARPA’s Huge Folding Telescope

fb share tweet share

MOIRA DARPA’s doing more than working on robots and super soldiers. It’s also developing the biggest space telescope in history, with the hopes of launching it to join the majority of communications satellites in geosynchronous Earth orbit in the Clarke belt, about 22,000 miles above Earth’s surface.

The MOIRA (Membrane Optical Imager for Real-Time Exploitation) telescope is being designed with something called membrane optics, which allow for higher resolution magnification, lighter weight, cheaper launches, and fewer deployment challenges. Membrane optics are a cutting-edge field in telescope lens development, and the main difference between them and conventional lenses is that membrane optics use diffraction, rather than the more conventional reflection or refraction.
