Although telescopes in space are close analogues of those on the ground, adapting them to work satisfactorily in earth orbit proved challenging, particularly for observations of sources other than the sun. For high energies, the basic detectors were familiar from laboratory physics but they were not adapted to determining positions. In the optical, a substitute for film had to be found and detectors with sensitivity and imaging had to be developed for the infrared. Of course, work in all wavelengths required three axis pointing, long exposures and data handling. The early solutions to these problems will be reviewed as a prelude to the Great Observatories.
