Russian rocket and space company "Energia" plans to engineer an orbital system of artificial daylight, which will reduce dark night time.

      Such artificial lighting system will be able to increase the duration of daytime and change the light-flux spectrum. They will be developed on the basis of space-reflector devices that are already available in the Earth orbit.

      In the new work, scientists will examine the subject of using such satellites and their safety, as well as emission spectra reflected from various metal coatings, which will cover the "mirror" of the spacecraft.

      Experts from the RSC "Energia" are considering the fact that artificial daylight may contribute to disruption of circadian rhythms in many living creatures, humans among them.
