AbstractIn the READ experiment, the in-fight measurement of the radiation, emanating from the shock layer generated in front of the USERS reentry module during the reentry flight, was successfully performed. The radiation generated at the shock layer was introduced into the onboard spectrometer in the USERS reentry module through the optical fiber. During the flight experiment, the spectrum of the radiation was recorded on the on-board data recorder and was successfully recovered after retrieval of the vehicle. The measured data shows that the spectrum was contaminated by the radiation other than the radiation emanating from the shock layer, and its intensity was stronger than was expected. The spectrum at the altitude of around 90 km shows a strong influence of the ablation gas while the spectrum at the lower altitude shows an influence of the albedo of Earth surface.
