Sustainable in-situ resource utilization on the moon

Planetary and Space Science, 2020
Abstract We propose that current in-situ resource utilization schemes based on mining of water resources on the Moon is unnecessary and unsustainable. Life support systems are capable of recycling with high efficiency. Burning of hydrogen propellant and oxygen is akin to the burning of fossil fuels.

A biologically inspired robot for lunar In-Situ Resource Utilization

2009 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2009
Successful long-term settlements on the Moon will need a supply of resources such as oxygen and water, yet the process of regularly transporting these resources from Earth would be prohibitively costly and dangerous. One alternative would be an approach using heterogeneous, autonomous robotic teams, which could collect and extract these resources from ...

Mars In-Situ Resource Utilization and Sulfur Concrete

Earth and Space 2021, 2021
Le projet ISRU de la NASA établit le besoin de matériaux in situ pour la base lunaire et l'habitation de Mars. Mars offre les conditions les plus favorables à l'habitation et à la poursuite de l'exploration de l'espace lointain. La compréhension des conditions planétaires révèle que les variations de température, les radiations solaires et le flux de ...

In-Situ Resource Utilization

2019
Human spaceflight is an expensive endeavor. Every kilogram that needs to be transported to low Earth orbit or beyond costs tens of thousands of dollars, with the cost increasing exponentially the farther humanity extends its reach into the solar system and beyond.
