In 2050, after over 50,000 people colonize Mars, Do Not Go Gentle, a private space company on Earth is planning to have its first human exploration of Saturn’s satellite, Titan. However, the dangers of radiation and the length of the trip from Earth jeopardize the mission for the humans on this mission to explore Titan. The mission will be using robotic AI’s and space ship that uses ion thrusters for propulsion. One of the topics that will be talked about in the sci-fi story of the mission to Titan is radiation. In space, radiation is one of many problems humans face when they travel beyond Earth’s atmosphere. There are two types of radiation, ionizing and non-ionizing radiation. Ionizing radiation is the process by which particles could…show more content…
These particles do the similar kind of damage as ionized radiation. [1] [2] There are two ways to measure radiation, an US unit and a SI unit. The first unit used to measure radiation is radiation-absorbed dose (rad) and it is use mostly in United States. The more commonly used measuring unit in the International Systems of Unit or SI is gray (Gy); 1 rad is equivalent to 0.01 Gy. Gray is also equivalent to one Joules per kilogram; however, radiation is measured in mGy or 1/1000 of a Gy when measuring absorption of a biological entity. [2] On Earth, the layers of atmosphere shield us from most of the radiation that could ever reach us but not all radiation is filtered like UV radiation. If there was no atmosphere, the high-energy particles can rip through the DNA’s links and cause mutations (usually in the form of cancer). When a high-energy particle affects the DNA/RNA or molecules, it can rip apart links or chains in the DNA/molecules. [3] The links that ripped apart a DNA can cause cancer and can affect chromosomes in the process. This process eventually leads to death if the DNA/RNA or cell is unable to repair the damage bonds. Exposure radiation can cause either an acute or chronic radiation poisoning. [3] Acute radiation is simply one large exposure to radiation either from high-energy/ionized or cosmic rays. Instead of having one large exposure of radiation, chronic radiation is having small doses over time, hence the Latin root
