Preparing EMU for Space Station

An enhanced Extravehicular Mobility Unit (EMU) for the Space Shuttle Program is discussed which is capable of meeting new requirements for SSF support. It is concluded that current SSF documents contain meaningful requirements that should be imposed on the SSF EMU to support SSF assembly and maintenance operations. These requirements fall within three broad areas which encompass revised accommodation aboard Shuttle and SSF, including interior environments; extended operating life resulting from the EVA mission model for SSF assembly and support; and operating safely in Station external environments that differ from those of Shuttle.
