Apollo-Soyuz Test Project Summary Science Report Volume I Astronomy, Earth Atmosphere and Gravity Field, Life Sciences, and Materials Processing

摘要

The Apollo-Soyuz Test Project science and technology program conducted by the Apollo crew consisted of 28 separate experiments, includ-ing 5 conducted jointly with the Soyuz crew. Cos¬mic sources of extreme-ultraviolet and X-ray radiation were discovered. The interstellar medium in the vicinity of the solar system was in¬vestigated. The solar corona was photographed using spacecraft occultation of the solar disk. The radioactivation of potentially useful gamma-ray detectors by cosmic particle bombardment was measured, and the effects of cosmic particle im¬pact upon living cells were investigated using three different techniques in three separate ex¬periments. The concentrations of two atomic species and the aerosol component of the upper atmosphere were measured by resonance absorp¬tion spectroscopy and solar extinction photom¬etry, respectively.
