The ETEEV payload will be installed on a Hitchhiker-palette onboard the Shuttle and will use plasma diagnostics mounted on the palette as well as on an articulated boom. Other objectives include contamination measurements, performance evaluation and optical diagnostics. This work presents first a review of recent papers on the instruments that are available to achieve these mission objectives; then the requirements and status of the ETEEV payload components are explained.
