Abstract: A heat-insulating multi-layer blanket for a spacecraft is disclosed including a stack of numerous heat-insulating layers, and an external layer superimposed on the stack. The external layer includes a second surface mirror (SSM) film, including a mirror layer placed under a fluorinated ethylene propylene (FEP) layer, and a polyimide layer joined to the SSM film. The blanket has two different configurations depending on the side of the external layer that is exposed to space.

Abstract: A satellite includes: at least one optical photography instrument including a main lens having an optical axis and the optical instrument having a field of view; at least one launcher interface system, intended for being removably secured to a satellite interface system of a launcher of the satellite; a linking device between the launcher interface and the optical instrument extending substantially parallel to the optical axis of the main lens between an upper end and a lower end; the launcher interface system is connected to the linking device by the lower end and the optical axis of the optical instrument is directed from the upper end towards the lower end of the linking device, the launcher interface system being outside the field of view of the instrument.
