The paper considers the description of phenomena in the own outboard atmosphere of spacecraft observed in the space experiment on the creation of the solar eclipse during the joint Soyuz–Apollo mission. It is shown that the transfer of solar radiation via gas-dust environment of own outboard atmosphere detected by the luminosity emanating from the shadow region outboard of the Apollo spacecraft when creating an artificial solar eclipse is an experimental result that confirms the theoretical conclusions on the similar exposure to radiation of the spacecraft with the nuclear power unit placed in the shadow of the radiation safety unit.

Modern spacecraft designs use elastic outrigger-type structural elements to accommodate equipment and devices. When the angular position of spacecraft changes and they stabilise in their orbits, these elements start to vibrate. In order to decrease the effect these vibrations have on the spacecraft dynamics, vibration damping delay time is introduced, amounting to several minutes. We present a methodology of determining design parameters for vibration damping systems that make it possible to damp vibrations in milliseconds
