What’s Fueling the Mars Mission: A look into liquid rocket fuel.
- Rocket scientists must choose a propellant that provides the most amount of impulse (how much thrust/push the fuel gives per unit of propellant), while having the lowest amount of mass (mass does not change depending on gravity).
- Cryogenic fuels are often made up of liquid hydrogen and liquid oxygen, are non-toxic, and burn much cleaner, but storing them is challenging and prone to cavitation, which can severely weaken the tanks carrying it.
- Rocket engines containing hypergolic propellant have both the fuel and oxidizer storage tank that are fed into the combustion chamber using tubes and valves where it ignites spontaneously but are corrosive, toxic, and carcinogenic.
- While cryogenic rocket engines are complex, and use lightweight machines called “turbo pumps” in the center of their engines to pressurize the liquid fuel as it feeds into the combustion chamber. Hypergolic propellant reactions do not require an ignition system, making the engine simpler and reliable.
- NASA is partial to LH2, and most rocket companies are leaning towards cryogenic fuel, due to its high impulse and non-toxic nature. Cryogenics seem to be the way to go.
- In the very near future we will get to experience the live viewing of humanity exploring yet another new celestial body, and for some this will be the second time experiencing such a wonder.
- The Starship Mars mission is using liquid methane and liquid oxygen as the fuel and oxidizer, both of which are extremely environmental-friendly (as far as rocket propellant goes anyway).
- Using hypergolic fuel in the present day seems to be looked down upon, due to the fact that it’s less efficient and much more toxic than its cryogenic counterparts.
- While the cooling of gasses is cumbersome and expensive, cryogenics seem to be the way to go.
- Cryogenic fuels are optimal for rocket usage because of their non-toxic nature. However, cryogenic fuels come with a lot of baggage; it takes a lot of energy and even more money to get elements down to such frigid temperatures.
