Energia Ozone Replenishment Satellite

Russian earth environment satellite. Study 1984. The eroding ozone layer of the earth would be replenished using a constellation of space-based lasers that would bombard the stratosphere at 30 km altitude for 30 years.

The Energia launch vehicle would launch 30 to 40 satellites, each with a mass of 60 to 80 metric tons, into a sun synchronous orbit at an altitude of 450 km. They would use on-board ion engines to move to operational orbits at 1600 km altitude. Each spacecraft would consist of:

• 600 m diameter solar collector
• 35 MWt oxygen-iodine laser of continuous function
• Equipment module with ion orbit correction engine
