The development of a satellite fitted with a 18-metre-wide mirror to enhance solar power production is a highly debated topic. The California-based startup Reflect Orbital aims to redirect sunlight onto areas between 5 km and 6 km wide "on demand", but several scientists oppose the move due to concerns that light beams could interfere with astronomical research, circadian rhythms, plant growth, human sleep, hormone release in humans and other animals, and negatively affect the migration of nocturnal species. The director of public policy at the American Astronomical Society has expressed concerns about the potential impact on the Earth environment, including human health, agriculture, and wildlife. The key facts surrounding this development include the startup's plan to launch a demo satellite into low Earth orbit before the end of the year, with plans to collect data and verify that installed safeguards can adequately control light beams. Reflect Orbital has also announced plans to launch 1,000 satellite mirrors by 2028 and 50,000 by 2035 if the pilot project is successful. However, environmentalists are concerned about the rocket fuel burned to get satellites into orbit, which will produce large quantities of carbon emissions. The European Southern Observatory estimates that just one of the sunbeams would appear around four times brighter than the full Moon in the illuminated area. The implications of this development for ESG and sustainable development are significant. If successful, Reflect Orbital's technology could provide clean, abundant energy, but it also raises concerns about light pollution, human health, animal welfare, and environmental impact. The lack of regulation and oversight by the FCC is also concerning, as it may lead to a proliferation of similar technologies without adequate consideration for their potential consequences. As such, this development highlights the need for more stringent regulations and guidelines for space-based renewable energy technologies to ensure that they are developed and deployed in a responsible and sustainable manner.
