Update #5 on Chris Hadfield’s condition

Fifth update on Chris Hadfield’s condition
by Raffi Kuyumjian, CSA’s Chief Medical Officer and Hadfield’s Flight Surgeon

Today is R+7, (Return+7 days). Just a week ago, Chris landed in the Kazakh steppes after 5 months in microgravity. He continues his readaptation process as well as multiple medical examinations. Yesterday, a very comprehensive vision exam was conducted using sophisticated tools to look at his retina in fine detail, his visual fields and optic nerve. These will complete the examinations started on Friday with the eye MRI. Also yesterday, a fitness test on a cycle ergometer was conducted to compare his fitness to the last test he performed on orbit a month ago.

Today is very busy with a balance test on a special platform, MRI and ultrasound of his spine, isokinetic testing to evaluate muscle strength, debrief sessions and finally, reconditioning at the gym.

Update #4 on Chris Hadfield’s condition

Fourth update on Chris Hadfield’s condition
by Raffi Kuyumjian, CSA’s Chief Medical Officer and Hadfield’s Flight Surgeon

The weekend schedule allowed Chris some “active rest”. His walk continues to improve despite some lingering dizziness and soreness in his back muscles, which are slowly getting used to working again in keeping the back straight and upright against gravity after 5 months of complete rest… Somewhat similar to having spent 24/7 in bed without moving for 5 months and then suddenly having to get up and walk!

Today a session of science data collection on Manual Control testing for coordination and reaction times using a motion flight simulator and car simulator amongst others: showing clear signs of improvement compared to 3 days ago when he completed the same tests! After the usual 2-hour daily reconditioning session, a few interview sessions will complete the day for Chris.

Update #3 on Chris Hadfield’s condition

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.

Final CSA Mission Blog - May 10-16, 2013

In story book fashion, CSA Astronaut Chris Hadfield returned to Earth after a five-month mission that rekindled for thousands – if not millions - their wonder, curiosity and passion for space exploration. Hadfield did not just come back to Earth – he brought space with him, for everyone.

Accompanied by his crewmates NASA astronaut Tom Marshburn and cosmonaut Roman Romanenko in their Soyuz TMA-07, the three touched down on the steppe of Kazakhstan at 10:31 p.m. EDT on May 13, 2013. Hadfield was the last of the three to be pulled out of the scorched remains of their capsule, but was all smiles and thumbs up to the rescue crew and media who greeted him.

Their return was not without a touch of drama, however, as a few days prior an ammonia leak was detected on the exterior of the International Space Station (ISS). Unsure of the cause, it was considered quite possible that their undocking with the ISS could be delayed. However, on May 11, NASA astronauts Tom Marshburn and Chris Cassidy got into their spacewalking suits and went to work, replacing a leaky pump in just under three hours.

The next day, Hadfield handed over command of the Space Station to colleague and long-time friend Pavel Vinogradov, ushering in the end of Expedition 35.

Before leaving the Station, Hadfield’s son Evan released Chris’ revised version of a Space Oddity, filmed almost exclusively throughout the modules of the Station. It was an immediate viral hit and sits at just under 13 million views at the time of this writing.

Going out on a high note, Hadfield is now rehabilitating in Houston, having been flown there soon after his landing in Kazakhstan. After five months in weightlessness he must readapt to a life where mics fall when let go, and even speaking feels different as the tongue has weight again. To find out more about the physical challenges Hadfield is going through, please see our flight surgeon’s updates on these matters.

On May 16, Hadfield performed his first news conference since returning to Earth, sharing his impressions of the mission and much more in his eloquent, thoughtful manner.

During five months in space, Hadfield became Canada’s first Commander of the International Space Station, performed over 130 science experiments, operated Canadarm2, and was at the centre of an integrated outreach campaign spearheaded by the CSA that captured headlines and hearts around the world.  The mission was a success on every level, and will serve to inspire the next generation of Canadian and international scientists, astronauts, engineers and artists. While on orbit, Hadfield reflected on the mission, expressing his sense that this was a shared experience between himself and the people of Earth.

To see how this historic mission unfolded, please go to our Expedition 34/35 page and our social media channels. Keep in mind, we will also be posting more videos, photos and updates of Chris Hadfield’s recovery and re-adaptation to Earth.  Thank you for following!

Update #2 on Chris Hadfield’s condition

An update on Chris Hadfield’s condition
by Raffi Kuyumjian, CSA’s Chief Medical Officer and Hadfield’s Flight Surgeon

Chris is already showing noticeable improvement in his walk and equilibrium since yesterday, but it usually takes about 3 weeks until we are confident a returning astronaut can return to driving. He will be driven to where he needs to be until then.

Today is a bit of a lighter day for Chris to help him recover from effects of gravity, as well as the jet-lag and the 24-hour flight to Houston from the landing site. He has a medical check, a 2-hour reconditioning session and short debrief meetings in addition to this morning’s press conference. He needs the rest as tomorrow is a full day of science data collection, medical checks and reconditioning.
