Multi-Layer Radiation Shields

Completed Technology Project

Project Description

Multi-Layer Radiation Shields, Phase I
Peregrine will develop a Multi-Layer Radiation Shield (MLRS) that will provide the equivalent insulation of a 30 layer 1.25� thick MLI blanket in the vacuum of space but on the surface of Mars. MLRS will provide superior properties to MLI but in a much smaller profile, MLRS can be accurately modeled and simulated so it is predictable, it can be pre-qualified, provide higher performance with no outgassing, and, when placed onto the exteriors of systems, can provide micrometeorite protection. The use of MLRS will, in a thin cross section, provide thermal isolation of the core of Fission Power Systems (FPS) to the environment of Mars. This will allow the FPS to operate at its intended design level; maintaining the heat within the core by creating a high performance insulation with an effective emissivity of less than 0.01 and an effective thermal conductivity of less than 0.005 W/mK.
