Visible and near infrared spectroscopy of Hayabusa re-entry using semi-autonomous tracking
McIntyre, Tim, Khan, Razmi, Eichmann, Troy, Upcroft, Ben, & Buttsworth, David (2012) Visible and near infrared spectroscopy of Hayabusa re-entry using semi-autonomous tracking. In Lewis, Mark (Ed.) Proceedings of the 50th AIAA Aerospace Sciences Meeting, AIAA, Gaylord Texan Hotel and Convention Center, Dallas, TX.
A ground-based tracking camera and co-aligned slit-less spectrograph were used to measure the spectral signature of visible radiation emitted from the Hayabusa capsule as it entered into the Earth's atmosphere in June 2010. Good quality spectra were obtained that showed the presence of radiation from the heat shield of the vehicle and the shock-heated air in front of the vehicle. An analysis of the black body nature of the radiation concluded that the peak average temperature of the surface was about (3100±100) K.
