Abstract

Future exploration missions involving humans will be conducted in more challenging environments. Current Extravehicular Activity (EVA) gloves have limited life, severely limit hand mobility and are a significant source of injury during spaceflight, making them unsuitable for future planetary exploration missions. The next generation of gloves will be designed with the goal of significantly improving performance, such as mobility and tactility, and tolerance of planetary environments. A multi-year effort under the High Performance EVA Glove (HPEG) project element at NASA's Johnson Space Center (JSC) strived to advance the EVA glove design by developing new prototypes and establishing a glove characterization protocol or standard to evaluate design changes. By researching hand-based test standards from other industries and targeting common EVA glove motions, tasks were compiled and down selected to create a set of activities to make up a standard EVA glove protocol. The objective of the standard protocol is to allow for quantitative analysis of glove performance data for the purpose of objectively assessing improvements among various glove designs or iterations. The following paper describes how this protocol was used in EVA glove testing of two new prototypes, as well as the current Phase VI Extravehicular Mobility Unit (EMU) flight glove. In addition, it also outlines the outcome of this effort and what it means for evaluation of EVA glove performance in the future.
