1. 1. Conceptualisation, Implementation and Commissioning of a Controlled Pyrolysis Rig : KTH Master Thesis Report

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Arjun Monga; [2023]
   Keywords : coke deposition; pyrolysis; catalysis; methane; sample; cooling channels; regenerative cooling; rocket engines; koksavsättning; pyrolys; katalys; metan; prov; kylkanaler; regenerativ kylning; raketmotorer;

   Abstract : Liquid methane has seen popular interest from industry and academia as a next-generation rocket fuel due to its favorable performance characteristics and potential for extra-terrestrial in-situ resource utilisation. Since the rocket combustion chamber and nozzle are subject to high heat loads, regenerative cooling is a standard method to achieve lower temperatures. READ MORE

3. 2. Making Space Exploration Sustainable: A Quantitative Assessment of Valuable Elements for Implementation of In-Situ Utilisation of Lunar Resources

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Bella Klaus; [2022]
   Keywords : Sustainable Development; extra-terrestrial resources; lunar resource mining; in-situ resource utilization; moon; space exploration;

   Abstract : Exploring the Solar System is an ongoing process of humanity that cannot be stopped. It requires large amounts of resources to explore space, which need to be acquired from somewhere. Resources mined on Earth cannot be diverted from vital productions on Earth as those required for energy systems transition and developing a sustainable society. READ MORE

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Edoardo Coppa; [2022]
   Keywords : Hybrid Propulsion; In-Situ Resource Utilisation; Lunar Applications; Metal Combustion;

   Abstract : The rapidly expanding space sector is at the forefront of innovation. New technologies are been continuously developed to allow more availability of space for a multitude of commercial or scientific goals. READ MORE

5. 4. Development of a System to Quantify Coking in Rocket Nozzle Cooling Channels

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Adam Parks; [2022]
   Keywords : methane; pyrolysis; reusable; carbon deposition; ozone cleaning; rocket engines; cooling channels; borescope; metan; pyrolys; återanvändbar; koldeposition; ozon-rening; raketmotorer; kylkanaler; boreskop;

   Abstract : Liquid methane is becoming an increasingly attractive rocket propellant due to its high performance characteristics and potential to support in-situ resource utilisation. Methane, however, when heated, can thermally decompose in a process known as pyrolysis. READ MORE

6. 5. Additive manufacturing of lunar regolith simulant using direct ink writing

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Billy Grundström; [2020]
   Keywords : 3D printing; additive manufacturing; lunar regolith simulant; european space agency; ESA; in situ resource utilisation; ISRU; direct ink writing; sintering;

   Abstract : In this work, the use of a lunar regolith simulant as feedstock for the direct ink writing additive manufacturing process is explored, the purpose of which is to enable future lunar in-situ resource utilisation. The feasibility of this approach is demonstrated in a laboratory setting by manufacturing objects with different geometries using methyl cellulose or sodium alginate as binding agents and water as liquid phase together with the lunar regolith simulant EAC-1A to create a viscous, printable ‘ink’ that is used in combination with a custom three-axis gantry system to produce green bodies for subsequent sintering.
