Specialists of RSC Energia proposed to increase the duration of daylight using system orbital lighting. These systems can be built based on the apparatus-reflectors with reflectors, which will be located in earth orbit. It is planned that the report will be presented at the Academic readings on cosmonautics.
Devices-reflectors will have a special metallic coating. It is assumed that they will not reflect all the light. Since the lighting at night can disrupt the biological reaction of the people in RSC Energia proposed to reduce the amount of reflected ultraviolet radiation and blue light.
