Improvements To Isru For Rocket Fuel Generation, Justin Sharp
Improvements To Isru For Rocket Fuel Generation, Justin Sharp
James Madison Undergraduate Research Journal (JMURJ)
The development of efficient in-situ resource utilization (ISRU) technologies is crucial for the establishment of an extraterrestrial, self-sustaining colony. The generation of rocket fuel at potential colony locations is necessary to provide the transportation of people and cargo to and from these locations.Three processes are discussed for the improvement of ISRU methods to generate rocket fuel: electrolysis and electrochemical improvements to the process of crude fuel production, physical and chemical methods for separation of gaseous H2 and O2, and materials and cryogenics engineering for storage and transportation of liquid hydrogen (LH2) and liquid oxygen (LOX). Storage and transportation of cryogenics …

MSU Graduate Theses
One of NASA’s key strategies is to learn more about the early solar system and its formation. Chondrites were formed from the most primitive materials at the collapse of the solar system and over time have been classified into different categories based on their elemental abundance. These chondrites have fallen to Earth and have even formed entities such as asteroids and planetary bodies. It has been found through studies that one of these chondrites is close to the elemental abundance of the Sun. The other types of chondrites were up to two orders of magnitude less in concentration …
