Multi-Layer Radiation Shields
Project Description
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.

Anticipated Benefits
The development and characterization of Multi-Layer Radiation Shields will optimize thermal control throughout all Fission Power Systems and provide higher reliability for both manned and unmanned systems for the exploration of Mars. In addition, MLRS will: �Provide thermal isolation of instruments. �Provide micrometeorite protection by having heavier outer layers in the MLRS. �Provide an integrated thermal control solution that also can integrate a structure via a heavier OD or ID wall to the MLRS. This can be applied to multiple systems within any spacecraft/satellite.
The following non NASA applications will have the ability to improve both performance and reliability using MLRS. �All of the areas identified in the post NASA above applications. �Thermal isolation of instruments and detectors for spacecraft and satellite applications. �Integrated structure with MLRS for lightweight, high performance thermal solutions for commercial satellites. �Use of MLRS technology will enhance environmental control of commercial buildings and large office centers. The use of MLRS for roofing systems could provide superior insulation leading to improved energy systems. More »
