An update on Chris Hadfield’s condition
by Raffi Kuyumjian, CSA’s Chief Medical Officer and Hadfield’s Flight Surgeon
Chris’ readaptation is going well and he continues to improve on a daily basis. His walk is more and more confident, the dizziness he was feeling is fading away every day and he is in good spirits!
He has a full day today of science data collection, amongst others, EEG recordings to evaluate how his sense of orientation and coordination are re adapting to gravity (see photo). He will also have a medical check with an ECG to evaluate his heart, as well as an eye ultrasound and Magnetic Resonance Imaging (MRI) of his eyes. These special eye examinations have become routine for all returning astronauts, since some of them have shown decreased vision during and after spaceflight, but the causes remain unclear. It is important to understand these and find ways to mitigate them before we consider longer duration missions to Mars for example.
The day will end with the usual 2-hour reconditioning session with the CSA exercise specialist Natalie Hirsch.

Maybe this helmet is used to verify if Chris Hadfield gained strange powers after exposure to cosmic rays…
