Benefits of an EMU Glove Active Heating System

Recent Shuttle extravehicular activity (EVA) missions have shown the need for improved thermal performance in Space Suit Assembly (SSA) gloves to successfully complete assembly of the International Space Station (ISS). Passive thermal design improvements have been successfully incorporated, however, additional improvements are still possible.

An Active Heated Glove Assembly was developed to aid in the prevention of cold hands and fingers during periods of rest and low metabolic activity. Environmental vacuum tests have shown that the system accomplishes its goals and measurably increases glove thermal performance.
