Simulant Name: TLS-01 Thailand Lunar Simulant
Availability: May Be Available
Fidelity: Basic
Developed By: SPACEZAB
Available From: SPACEZAB (

The Thailand Lunar Simulant (TLS) is a lunar surface environment simulant produced by the SPACEZAB company as a tool for researching and developing lunar technologies. An online reference describes how it was sourced from a basalt quarry in Chanthaburi province, and that the chemistry of this basalt is a suitable analog for lunar mare samples returned by Apollo. The basalt was then processed using a Los Angeles Abrasion Machine, and sieved to remove the <15 mm size fraction to use as the simulant.
