It is highly probable that human space exploration objectives will drive the next generation Extravehicular Activity (EVA) spacesuit to require design elements capable of providing thermal insulation protection across multiple environments. Although NASA has not adopted any specific human exploration design reference missions beyond International Space Station, the most recent NASA strategic plan includes operations in low-earth orbit, in the near-earth neighborhood and in planetary environments. NASA-funded efforts conducted to date indicate that aerogel composite technologies show promise in terms of thermal insulation performance (relative to existing materials) for all human exploration environments, including high vacuum and gaseous environments. The project described herein explored an aerogel-based EVA Glove Thermal Micrometeoroid Garment concept; focusing on developing techniques to integrate a NASA furnished aerogel insulation into a high fidelity Exploration Thermal Micrometeoroid Garment (ETMG) Prototype. The effort culminated in the design and fabrication of a pair of high fidelity prototype ETMGs for use with David Clark Company Incorporated (DCCI) Phase VIId EVA Gloves. While budget and schedule did not allow for extensive predelivery testing of this ETMG prototype, the preliminary test results are promising, corroborate anecdotal performance data for the integrated aerogel material, and suggest that the use of aerogel materials within the ETMG assembly preserves (to the extent possible) the mobility inherent in the DCCI Phase VIId EVA Glove.
