Lunar Polar Environmental Testing: Regolith Simulant Conditioning

, 2014
As ISRU system development approaches flight fidelity, there is a need to test hardware in relevant environments. Extensive laboratory and field testing have involved relevant soil (lunar regolith simulants), but the current design iterations necessitate

High-Energy Detonation Based Lunar Regolith Simulation for Resource Utilization

Aerospace
As international lunar exploration shifts from mainly understanding the Moon to equally prioritizing its utilization, the requirement for highly similar lunar regolith simulants has grown.

Progress of the NASAUSGS Lunar Regolith Simulant Project

, 2009
Beginning in 2004 personnel at MSFC began serious efforts to develop a new generation of lunar simulants. The first two products were a replication of the previous JSC-1 simulant under a contract to Orbitec and a major workshop in 2005 on future simulant

Spirulina supported plant growth in regolith simulants and elevated levels of CO2

Frontiers in Space Technologies
IntroductionA key element for sustainable off-world habitation is the ability to grow food through in-situ resource utilization (ISRU). Growth substrates are required to overcome the challenges of ISRU in the space environment, including the use of ...

Lunar Dust Simulant in Mechanical Component Testing - Paradigm and Practicality

, 2008
Due to the uniquely harsh lunar surface environment, terrestrial test activities may not adequately represent abrasive wear by lunar dust likely to be experienced in mechanical systems used in lunar exploration.

Determination of the Dynamic Angle of Repose of Lunar Regolith Simulants

Geosciences
The determination of the dynamic angle of repose (DAR) of lunar regolith simulants is essential for modeling material behavior during in situ resource utilization (ISRU) processes and lunar surface operations.

Sources and Transportation of Bulk, Low-Cost Lunar Simulant Materials

, 2013
Marshall Space Flight Center (MSFC) has built the Lunar Surface Testbed using 200 tons of volcanic cinder and ash from the same source used for the simulant series JSC-1. This Technical Memorandum examines the alternatives examined for transportation and

Survivability of Amino Acids in Lunar Soil

The Planetary Science Journal
We present a laboratory investigation on the survivability of amino acids in lunar simulant soil under conditions similar to the lunar surface. Survival rates of various amino acids are quantified using ultra-high-performance liquid chromatography in ...
