Abstract
Photographs of a ground-based laser beacon were taken by astronauts on board the Skylab spacecraft. Unexpected large and elliptical laser-beam images were recorded. The photographic results are presented and discussed in terms of possible atmospheric scattering mechanisms. Current beacon experiments with the Landsat spacecraft are also discussed.
