<ul><li>NASA/Hamilton Sundstrand/ILC Dover</li>
<li>The EMU provides a crewmember with life support and an enclosure that enables an EVA (Extravehicular Activity). The unit consists of two major subsystems: the Primary Life Support Subsystem (PLSS) and the Space Suit Assembly (SSA). The EMU provides atmospheric containment, thermal insulation, cooling, solar radiation protection, and micrometeoroid/orbital debris (MMOD) protection.</li></ul>
