USE OF EXTRATERRESTRIAL RESOURCES FOR HUMAN SPACE MISSIONS TO MOON OR MARS In situ resource utilization (ISRU) is a means of converting extraterrestrial indigenous resources into various products that are needed for a space mission. According to NASA, by utilizing such resources, the amount of material that must be brought from Earth could be reduced, thus potentially reducing the cost of a space mission - indeed, several NASA documents have referred to ISRU as "living off the land".

Use of Extraterrestrial Resources for Human Space Missions to Moon or Mars is the only book that examines the reality rather than the dream of ISRU. Using all the available data as well as the author's own extensive knowledge, it carries out approximate estimates of the costs of implementing ISRU on the Moon and Mars. In addition, the book provides a detailed review of various ISRU technologies and how these might have potential benefit for space missions. Controversially, it comes to the conclusion that Mars ISRU might have merit but that there is no gain for implementing a lunar ISRU.
