Researchers from Harvard University, the jet propulsion Laboratory of NASA and the University of Edinburgh have identified a method by which separate regions on Mars can be made fit for life. This may be the first stage of terraforming the red Planet. About it reported in a press release on Phys.org.
According to experts, to simulate the greenhouse effect using the aerogel of silica. The simulation results showed that the layer made of this substance, of a thickness of two to three centimeters, can transmit visible sunlight sufficient for photosynthesis, but to block UV radiation. In addition, the temperature under the dome of the aerogel will rise above the melting point of ice, thereby obviating the need for internal heat source.
A similar phenomenon is happening on Mars in the vicinity of the polar ice caps containing water and large amounts of carbon dioxide. Frozen carbon dioxide retains heat so under the ice there are pockets of high temperature. Aerogel is also characterized by low conductivity. This is achieved by using layers of silicon dioxide, which slow the heat transfer. The high porosity of the aerogel allows light to pass through the material.
