Ceres and In Situ Resource Utilization

2015
Although Mars is the most frequently cited destination for manned missions, Ceres, with its shallow gravity well and enormous water resources, may be even a more interesting site, and one that becomes reachable via electric propulsion. This chapter describes a roundtrip mission to the Ceresian environment, and also explores the potential for in situ ...

Solar Thermal Technology for In-Situ Resource Utilization

3rd International Energy Conversion Engineering Conference, 2005
*† ‡ In-Situ Resource Utilization (ISRU) processes require thermal energy at various temperatures. Chemical recovery process (pyrolysis, gas-solid reactions, gas-liquid or threephase reactions and desorption) requires thermal energy at temperatures from 1000 K to 2500 K. Manufacturing processes (hot liquid processing, sinter forming, composite forming,

Commercial viability of lunar In-Situ Resource Utilization (ISRU)

Planetary and Space Science, 2020
Abstract In this paper, we propose an architecture for lunar in-situ resource utilization (ISRU) which can provide propellant, typically cryogenic hydrogen and oxygen, to a cislunar aggregation point in support of future space missions to the Moon, Mars, and beyond at a price competitive with commercial delivery from Earth.

In Situ Utilization of Indigenous Resources

2009
Planning for a human mission to Mars dates back to the 1950s, but in the 1990s, a new aspect was introduced: In Situ Resource Utilization (ISRU). In its simplest form, it utilizes indigenous Mars resources to produce propellants for ascent from Mars, thus significantly reducing the mass that must be transported to Mars. If accessible water can be found

In-situ resource utilization technologies for Mars life support systems

Advances in Space Research, 2000
The atmosphere of Mars has many of the ingredients that can be used to support human exploration missions. It can be "mined" and processed to produce oxygen, buffer gas, and water, resulting in significant savings on mission costs. The use of local materials, called ISRU (for in-situ resource utilization), is clearly an essential strategy for a long ...

Solar Energy System for In-Situ Resource Utilization

Space 2004 Conference and Exhibit, 2004
Physical Sciences Inc. (PSI) has been developing the Optical Waveguide (OW) system for solar energy utilization. In this system, solar radiation is collected by the concentrator which transfers the concentrated solar radiation to the OW transmission line.

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.

(Invited) Electrochemical Processes for in Situ Resource Utilization

ECS Meeting Abstracts, 2019
In situ resource utilization (ISRU) is the practice of generating resources when humans are away from Earth. The goals of ISRU include the generation of rocket propellants, building materials, and life sustaining commodities from such resources as the Mars atmosphere, lunar regolith, and even trash.

In-Situ Resource Utilization for Lunar and Mars Exploration

45th AIAA Aerospace Sciences Meeting and Exhibit, 2007
In-Situ Resource Utilization is the collection, processing, storing and use of materials encountered in the course of human or robotic space exploration that replace materials that would otherwise be brought from Earth to accomplish a mission critical need at reduced overall cost and risk.

In Situ Resource Utilization: Excavation to Support Other Operations

Space 2002 and Robotics 2002, 2002
Missions to surfaces of planetary bodies and asteroids, whether manned or robotic, will encounter dust, soil, and rock fragments, possibly combined with ice, which will affect mechanical operations. Contact with these materials may be incidental or intentional in the case of digging or drilling operations.
