The largest spyglass mirror to be lightweighted using a mechanical cutting proces will eventually give NASA a great view of black retreats galactic evolution, and other solar schemes The mirror, part of NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) frame will be part of the world's largest airborne observatory.
Engineers at the REOSC a French company, reconfigured the 27-m primary mirror of the spyglass to be light enough to confront the stringent weight requirements of an airborne spyglass yet strong enough to withstand aspect to the harsh ...
