- Abstract
Go green!! This phrase is applicable to the space industry as well. With NASA now embarking on its human missiles project, how will they fuel the deep exploration rockets long term? One efficient practice is through the use of cryogenic fuels. These super cold fuels such as liquid hydrogen and liquid oxygen are the ideal solutions when contained in extremely cold environments. These Cryogenic fuels can be thought of as “green fuels” even in space. When hydrogen and oxygen combine as a mixture, they yield water. If there will ever be “fuel stations” in space, cryogenic fuels will deliver high efficiency. Even with their complexities, they are greener, safer, and cheaper than many other fuels options. The environmental advantages of cryogenics such as eliminating the use of fossil fuels are benefits as to why these fuels are they smartest way to go. Costs will be cheaper when we deviate from a barrel of oil. Currently cryogenic propellant storage maintains loss rate below 3% a month on two year mission to mars. These green fuels are subject to Zero Boil Off (ZBO) fuel storage system that will ensure the liquid will remain in its liquid state for the duration of the time. With the use of cryocoolers, these liquids will remain at a low temperature. At least four companies in the US have budgeted to show that by using cryogenic fuels, we can reduce the use of the current large vehicles for extended space exploration. Even though the use of cryogenics is over 50 years old, more research has been developed in improving the complexities of the fuel. With NASA’s current budget cuts, the constant cost saving techniques will be more explored. Once we can overcome the complexities of the handling, maintaining, and safety issues of cryogenics, they will be extremely beneficial for long term uses. These green fuels are very safe for the environment long term in helping us reduce our carbon footprint on earth and in space. Cryogenics is the most efficient, green, and cheap option for fueling NASA’s upcoming deep exploration space expeditions.
