JSC-1A can geopolymerize in an alkaline solutions resulting in a hard, rock-like, material. [7] [8] Tests show that the maximum compressive and flexural strength of the 'lunar' geopolymer is comparable to that of conventional cements. [8] Geopolymers from lunar (JSC-1A) and Martian (JSC MARS-1A) dust simulants produced at the University of ...
A small pile of JSC MARS-1A [1] A jar of Martian regolith simulant JSC MARS-1A. Martian regolith simulant (or Martian soil simulant) is a terrestrial material that is used to simulate the chemical and mechanical properties of Martian regolith for research, experiments and prototype testing of activities related to Martian regolith such as dust mitigation of transportation equipment, advanced ...
The best mixture for tensile and compressive strength is 65% JSC-1 lunar regolith simulant and 35% sulfur, with an average compressive strength of 33.8 MPa and tensile strength of 3.7 MPa. Addition of 2% metal fiber increase the compressive strength to 43.0 MPa [ 13 ] Addition of silica also increases the strength of the concrete.
A small pile of JSC MARS-1A soil simulant [52] Research on Earth is currently limited to using Martian regolith simulants , such as the MGS-1 simulant produced by Exolith Lab, [ 53 ] which are based on the analysis from the various Mars spacecraft .

Basalt fibre has also been made from lunar regolith simulators. Successful tests have been performed on Earth using two lunar regolith simulants MLS-1 and MLS-2. [47] In August 2005, NASA contracted for the production of 16 tonnes of simulated lunar soil, or lunar regolith simulant material for research on how lunar soil could be used in situ ...
This color scheme is the most varied color scheme because it uses six colors which are arranged into three complementary color pairs, or it could be seen as two color schemes that are complimentary to each other—such as two triadic color schemes or two near-analogous color schemes—or adding a complementary pair to a rectangular tetradic ...
The Lunar Sample Laboratory Facility (LSLF) is a repository and laboratory facility at NASA's Lyndon B. Johnson Space Center in Houston, Texas, opened in 1979 to house geologic samples returned from the Moon by the Apollo program missions to the lunar surface between 1969 and 1972. The facility preserves most of the 382 kilograms (842 lb) of ...
