Abstract

Current plans for space exploration are calling for more information about materials—at ever lower temperatures. The University of Arizona is making a 2-m prototype mirror for the Next Generation Space Telescope (NGST) to operate at 35 K.1 Previous low temperature measurements of thermal expansion have been limited to temperatures down to 77 K, except for the very low temperature studies of White et al.2,3,4
