Paper Abstract

Cost and weight data for optical and radio telescopes are analyzed to derive scaling laws appropriate to the design and costing of very large telescopes of the future. A scaling law exponent close to the 2.0 power of aperture diameter is found for telescopes of comparable sophistication ranging from a 0.4 m to 5.0 m aperture, in contrast to the often cited 2.7 exponent. Predicted characteristics for a 25-meter aperture steerable dish Next Generation Telescope (NGT) are 5 x 10 6 kg, 20 $/kg and a total cost of 1.3 x 10 8 $.
