New Projects for Rocket and Space Travel) [3] and 1978 „Der Weltraumspiegel“ (The Space Mirror). [4] For cost reasons, Hermann Oberth's concept envisages that the components should be produced from lunar minerals on the Moon, because its lower gravitational pull requires less energy to launch the components into lunar Orbit.
Since the conception of the idea in 1923, 1929, 1957 and 1978 (Hermann Oberth) and also in the 1980s, space mirrors have mainly been theorized as a way to deflect sunlight to counter global warming and were seriously considered in the 2000s.
Schematic with five proposed methods for solar radiation modification technologies. Solar radiation modification (SRM) (or solar radiation management or solar geoengineering), is a group of large-scale approaches to limit global warming by increasing the amount of sunlight (solar radiation) that is reflected away from Earth and back to space.
The project was the brain child of Vladimir Syromyatnikov, who served as the project's lead engineer. [1] Originally devised as a solar sail, Syromyatnikov pivoted to using the proposed hardware as a space mirror. The project consisted of two experiments: the Znamya 2 experiment and the failed Znamya 2.5, plus the proposed Znamya 3.
The use of solar mirrors as a form of passive daytime radiative cooling for solar radiation management has been proposed to address local temperature increases as well as to decrease global warming. [3] Propositions have focused on the usage of solar mirrors both on the Earth's surface and in space.
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
As a method to address global warming, the IPCC 2018 report indicated that the potential for global temperature reduction was "small," yet was in high agreement over the recognition of temperature changes of 1-3 °C on a regional scale. [1] Limited application of reflective surfaces can mitigate urban heat island effect. [6]
