A driving concern of the Lunar Ultraviolet Telescope Experiment (LUTE) preliminary design study was the degradation of the LUTE optical figure due to thermal deformations, during a temperature cycle of 65 K to 265 K at the reference 40 deg latitude, 0 deg longitude landing site. A multidisciplinary analysis process was developed, temperature effects were characterized, and primary mirror thermal deformations calculated for use in the optical analyses. Trade studies evaluated the qualitative performance of various design schemes. Results indicated that kinematic mirror supports with bottom-mounted flexures rendered less optical disturbance under thermal loading than mirror supports at the inner or outer periphery. Another trade indicated that a telescope's baseplate should be athermalized by matching thermal distortion coefficients. A comparison of three materials for the primary mirror predicted that silicon carbide would be the best material for resisting thermally induced figure deformations on the moon.
