Abstract The observation of EUV emissions of comet Halley and its plasma-gas environment by means of rocket- or satellite-borne resonance absorption cell spectrophotometer devices is planned. The technical outlay of the payload, the estimated EUV intensities, and the scientific objectives of this mission are presented. Due to complete suppression of the geocoronal He I emissions by He I resonance absorption cells, a quantitative identification of the cometary object in the He I 58.4 nm line is possible, if the He/H abundance ratio in the evaporating cometary matter is higher than 4.0 E-4.
