Znamya (satellite)

The Znamya project was a series of orbital mirror experiments in the 1990s that intended to beam solar power to Earth by reflecting sunlight. It consisted of two experiments – the Znamya 2 experiment, and the failed Znamya 2.5 – and the proposed Znamya 3. The project was abandoned by the Russian Federal Space Agency after the failed deployment of the Znamya 2.5.
