Mars ISRU technology

2012
The major opportunities to use ISRU on Mars include propellants for ascent from the Martian surface and water and oxygen for life support. Mars soil contains oxygen but processing the soil is difficult.

NASA's Centennial Challenges Contributions to ISRU

47th AIAA Aerospace Sciences Meeting including The New Horizons Forum and Aerospace Exposition, 2009
In-Situ Resource Utilization (ISRU) will be critically important for long-term sustainability of operations on the Moon or Mars. NASA is seeking to advance technologies needed for ISRU through Centennial Challenges -NASA’s prize competitions for the citizen inventor.

Solar Thermal Power System for Lunar ISRU Applications: Result of ISRU Analog Test, Mauna Kea, HI

AIAA SPACE 2010 Conference & Exposition, 2010
This paper discusses the development, deployment and operation of the optical waveguide (OW) solar thermal power system ISRU applications at the ISRU analog test site on Mauna Kea, HI. In this solar thermal system, solar radiation is collected by the concentrator array which transfers the concentrated solar radiation to the OW transmission line made of

An Asteroid Regolith Database for ISRU

AbstractWe have developed the first database of asteroid regolith properties: fifty asteroids so far, to aid space resource utilisation workers. The physical parameters: grain density, grain size, near surface bulk density and porosity are provided of a collection of the asteroids.

ISRU-Based Development of a Lunar Water Astroparticle Observatory

57th International Astronautical Congress, 2006
Abstract Lunar Water Astroparticle Observatories are proposed to be fabricated at the Lunar North and South Poles by use of Lunar in situ resources. These observatories will consist, initially, of a 10 m × 10 m × 10 m basin excavated, to be filled with 1000 metric tons of water from the in situ resources at the Polar Regions.

A Nuclear Powered ISRU Mission to Mars

AIP Conference Proceedings, 2006
Space exploration has always been drastically constrained by the masses that can be launched into orbit; Hence affordable planning and execution of prolonged manned space missions depend upon the utilization of local. Successful in‐situ resources utilization (ISRU) is a key element to allow the human presence on Mars or the Moon.

A Fixed Mars ISRU Base for Accelerated Exploration

AIAA SPACE 2009 Conference & Exposition, 2009
We have re-examined in situ resource utilization (ISRU) from the perspective of the extraordinarily successful on-going Mars Exploration Program, more than 30 years after we first alerted the science communities to the break -through advantages ISRU offered for Mars round-trip missions.

Employing ISRU Models to Improve Hardware Designs

48th AIAA Aerospace Sciences Meeting Including the New Horizons Forum and Aerospace Exposition, 2010
An analytical model for hydrogen reduction of regolith was used to investigate the effects of several key variables on the energy and mass performance of reactors for a lunar in-situ resource utilization oxygen production plant. Reactor geometry, reaction time, number of reactors, heat recuperation, heat loss, and operating pressure were all studied to
