Abstract
A cryogenic 3.5 m mirror is being developed which weighs 140 kg, that could be incorporated into a telescope and launched to a high orbit by the Shuttle or number of other vehicles. Such a space mission would complement those already planned for scaled down tests of the unfolding of the next generation space telescope (NGST) mirror segments and the sunshade. Much would be learned by running the mirror at cryogenic temperature, with a new infrared array to make preliminary observations in the 2-4 μm dark sky window and a charge coupled devices to check optical image quality.
