The impact was not as visually prominent as had been anticipated. However the infrared camera did capture a thermal signature of the booster’s crater. Project manager Dan Andrews believed that this was due to pre-crash simulations that exaggerated the plume’s prominence (some simulations were not done by NASA).
Another possibility was that lighting was not sufficient for adequate photography, and would result in the need for image processing to increase clarity. The depth of Cabeus could be too great. This may be confirmed from Laser Ranging data collected previously by Chandrayaan-1, and preceding data from KAGUYA.
Hubble Space Telescope co-investigator Alex Storrs said: “A preliminary analysis of the STIS spectra do not show any clear evidence for hydroxyl, but further analysis is needed.”
