Abstract: A satellite, especially a geostationary satellite, which includes: at least one face (5) which is used as a thermal radiator for the equipment carried on board the satellite (1) and is arranged in the path of the solar radiation (9); at least one solar panel (7) which is a generator of electricity, which is pointed continuously toward the sun and projects from the face (5); and a screen (14) secured to the solar panel (7), which is arranged at the periphery of the satellite and which stops the solar radiation (9) directed toward the face (5). The satellite is noteworthy in that the solar panel (7) is arranged centrally with respect to the face (5) and the screen (14) is secured to the solar panel (7) by an arm (15).

Abstract: A device for temporary edge to edge securement in space of two parts along a contacting surface comprising:a plurality of retaining members distributed in pairs on either side of such contacting surface on each of said respective parts and a plurality of temporary connection members adapted to maintain them coupled to one another, with the rataining members in each pair being provided with complementary raised members for retainment thereof one relative to the other according to a longitudinal direction parallel to said contacting surface in at least one direction, said retaining members in each pair forming conjointly a bulging tenon oriented longitudinally engaging a narrowing groove formed in a rider constituting a temporary connection member for such pair of retaining members, andan automatic release mechanism comprising a coordination element connected to the plurality of temporary connection members and adapted to disengage the latter relative to said plurality of retaining members under the action of a
