The liquid fuel rocket is important today because it has helped the U.S. explore space and put things into earth's orbit like satellites, the ISS, or the Hubble Space Telescope. This invention has changed our lives in important ways like discovering whole other galaxies, giving people access to things like the GPS and phone communications worldwide. In addition, giving us all kinds of information about our own galaxy.
Liquid fuel rockets are still used today, needing an oxidizer and fuel to work. Today NASA is trying to use liquid Hydrogen as a fuel source because it is very light and extremely effective. In addition it burns with extreme intensity (5, 5000 ° F). When liquid hydrogen is combined with liquid oxygen, liquid hydrogen has the highest efficiency in relation to how much fuel is used, compared to any other rocket fuels. Since liquid oxygen and liquid hydrogen are both cryogenic, meaning they both can be turned into a liquid, making more storage space for each
