EUV-FUV spectroscopy of TSS optical Phenomena

Summary We propose to use the IEH (International Ultraviolet Hitchhiker), a multidisciplinary facility (Astronomy, Solar System, Earth's atmosphere) to be mounted on the Shuttle pallet as a Hitchhiker flight opportunity, in order to obtain 2D images in the EUV-FUV ((400÷1300) ?) of the optical phenomena occurring in the neighborhood of the TSS satellite. These peculiar phenomena, not detectable during the first TSS mission, are primarily due to the interaction of a high-potential conductive body with the surrounding ionospheric plasma.
