One is to surround the spaceship with magnetic shield. The idea was inspired by the protective layer – the atmosphere - Earth has against radiations. We think we can put together a magnetic field by using an electromagnet. It would create electric current through a wire, which will enter the walls of the settlement leading to a magnetic shield that doesn’t hurt the astronauts. Another solution proposed is also to surround the spaceship, but this time with tanks of water, close to 3 metres thickness, in order to absorb the particles. This idea isn’t the most efficient, because the ship should not carry heavy and it is also quite expensive. Last but not least, our astronauts could wear lead vests, similar to those patients wear when having an x-ray. The problem is that the level of radiation to which we expose ourselves when having an x-ray can’t even remotely approach the level of radiation astronauts need to face in a trip. Therefore, the lead vests need to be thicker than the one used in a medical context, because those aren’t enough. Having more than one economical and efficient solution to protect our astronauts from radiation encourages us to believe that we can assure them that this issue is taken care of and they will have a safe travel to Venus.
Energy The atmosphere of Venus can be located even above 80km altitude compared to Earth having atmosphere at 10km high, while on Venus, at 50km pressure becomes the same as Earth at sea level. The large amount of CO2 in Venus atmosphere together with water vapor and sulfur dioxide create a strong greenhouse effect, trapping solar energy and raising the surface temperature to around 467 °C, hotter than any other planet in the Solar System, despite being second planet from the Sun, after Mercury. Sun is made from hydrogen gas, the lightest element in the universe. Through fusion process, 4 hydrogen atoms produce one atom of helium. Fusion releases energy that cause Sun to be hot and bright. As hydrogen form helium, supply of hydrogen decreases and over time, in 5 billion years, Sun will run out of hydrogen and start to cool down. Energy coming from the Sun is energy produced through nuclear fusion. Plants uses photosynthesis to harvest energy from the sun and by using solar cells we can harvest energy from the Sun as well just as plants do. Even on Earth, we try to convert from fossil fuels to more sustainable energy, like solar energy. Solar energy is an accessible source of energy in space and settlement system can be powered through solar panels as on our planet half of the day would be dark, while space has continuous solar illumination. Therefore, there are several sources of energy in space that can be converted into electricity to sustain the settlement: solar energy nuclear energy alternative energy - acoustic and kinetic
Solar energy We obtain solar energy by placing solar panels as we cover the settlements with small modular solar cells on the exterior. Energy gathered from the solar arrays will be converted to electrical energy and stored into nanocapacitors devices. Apart from solar panels installed on the settlement exterior and nuclear energy generated on the settlement, we can also use solar satellites in the orbit equipped with solar panels which will constantly gather sun light and transform it into electrical energy and energy will be transferred to settlement by power beaming.
