ISRU Technologies to Support Human Space Exploration
SAE Technical Paper Series, 2004<div class="htmlview paragraph">In-situ resource utilization (ISRU) is an important part of current mission architectures for both a return to the Moon and the eventual human exploration of Mars. ORBITEC has developed and demonstrated an innovative direct energy processing approach for carbon-reduction of lunar and Martian regolith that can ...

The lunar-soil particle size distribution is very broad. In addition, because of the irregular particle shapes, the specific surface area is high: approximately 0.5m2/g. In fact, lunar soil particles have about eight times more surface area than an assemblage of spheres with the equivalent particle size distribution.

ISRU Propellant Selection for Space Exploration Vehicles
49th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2013Chemical propulsion remains the only viable solution as technically matured technology for the near term human space transportation to Lunar and Mars. Current mode of space travel requires us to "take everything we will need", including propellant for the return trip.

Magnesium as an ISRU-Derived Resource for Lunar Structures
Journal of Aerospace Engineering, 2012AbstractMagnesium is one of the most pervasive metals in lunar soil and has many characteristics that make it applicable to in situ refining and production. This somewhat overlooked alkaline earth metal is easily cast, used, and recycled, characteristics that are required in the Moon's harsh environment.

ISRU-Based Development of a Lunar Water Astroparticle Observatory
57th International Astronautical Congress, 2006Abstract 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.

Solar Power System for Lunar ISRU Applications
48th AIAA Aerospace Sciences Meeting Including the New Horizons Forum and Aerospace Exposition, 2010This paper discusses the development of a solar power system for lunar ISRU applications. In this solar thermal system, solar radiation is collected by the concentrator array which transfers the concentrated solar radiation to the optical waveguide (OW) transmission line made of low loss optical fibers.

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.Amara L. Graps +3 more

A Nuclear Powered ISRU Mission to Mars
AIP Conference Proceedings, 2006Space 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.
