Scientific paper

The 4kW solar array under development in Europe for the shuttle launched, NASA space telescope is described. The array is designed to meet the requirements of astronaut in-orbit maintenance and contingency operation; the particularly demanding requirement to function mechanically and electrically after 5 years in low earth orbit, having encountered some 30,000 thermal cycles; the requirement to satisfy the stringent constraints on array dynamics imposed by an astronomical observatory telescope with a pointing stability of thousandths of an arc second; and the need to be retractable, following a period of service in orbit, for return to earth in the shuttle orbiter bay.
