As for the material of the space, “small is beautiful” has followers. US space budgets have set a $12.5 million game for the development of the SSTP (Small Spacecraft Technology Program), which consists of miniature satellite manufacturing.
The first satellite will weigh only 230 kilos and is expected to be launched in 1995. The mission of these mini-elites will be to detect the resources of the Earth, but they will also serve to industries.
