Mission facts.
• Space mission “Solar Sail” is intended for investigating of possibilities of control and the dynamics of the spacecraft subjected to solar light.
• It had light thin-film large-area (600 m2) panels (Sails).
• Was launched on June 21, 2005.• Unfortunately, the first stage of the Volna rocket
didn’t complete its scheduled burn, and the spacecraft did not enter orbit.
Information characteristics
• Downstream: up to 128 Kbps
• Upstream: up to 1 Kbps
• Onboard data storage: 8 Mbytes

Conclusion
• Functionality and cost parameters of the mission are strongly depended of the ISS effectiveness.
• Effective Information Support System can be reached by:– Using of unified equipment and resources.– Using of modern technologies and methods.– Using of experience from other industries.
