Abstract:
This paper studies the options for renewable energy sources in the context of the colonization of other planets. The earth is currently heavily affected by pollution. This has led to effects such as global warming. Colonization of other planets is a good backup plan in case of irreparable damage to planet Earth. This can happen either by defeating the harsh conditions of the planets in our galaxy, or by building a spaceship fast enough to reach the habitable planets in other galaxies in a time comparable to human life. Scientists are currently studying terraforming planets such as Mars. Although we do not yet have the technology to do this, in the future it will be possible to easily terraform new planets and we need energy to live there. The main source of energy studied in this paper are solar energy satellites (SPS), which are both non-invasive and efficient. There are several types of STS: Planar, multi-rotary joints (MR) and Module Symmetrical Concentrator (MSC), which collects solar energy in the two huge panels and is transmitted through a part of the joint to the antenna, and it transmits wirelessly to the planet. Because these systems have an equivalent antenna architecture, the differences occur mainly in the dimensions of the solar arrays and their power joints. For MR the huge solar matrix is replaced by many separate small solar sub-matrices, and the high power pivot joint is replaced by many medium power rotary joints, the modular design makes the system easier to assemble. In the case of MSC there are 2 large reflectors that rotate so as to collect and reflect incident sunlight on two centrally located photovoltaic panels. Therefore, the use of renewable energy sources is one of the most important criteria to live harmoniously on a new planet. Solar energy taken directly from space is a feasible and efficient option at the moment.
