This aerostate is to be designed and developed in the framework of the space cooperation between USSR and France. The mission of the ballon vehicle is to collect detailed information over various Mars surface sites. To meet this objective, the balloon flies daily using solar heating and moves to the next landing site pushed by the local winds. Therefore, the each day the aerostat will ivestigate a different place during its lifetime. The main challenge is to achieve a lightweight balloon, needed by the very low atmospheric density of Mars, able to provide a workable instrument platform. Several consepts have been considered, including a single gas balloon to dual balloon systems combining aerostatic gas and solar hot air effects. For all these consepts, the mechanical, thermooptical and leakage films properties have a major impact on the overall performance. Emphasis has been put on technological aspects as well as on the materials themselves and the envelopes manufacturing process. 1 2 Sel f-contained smal l space tether systems Alpatov A.P., S.V., Be l onozhko P.A., :Khoroshilov V.
