In just a couple of days a Soyuz rocket will lift off from the Baikonur Cosmodrome, carrying NASA astronaut Tom Marshburn, Canadian Space Agency astronaut Chris Hadfield, and Russian Federal Space Agency cosmonaut Roman Romanenko within the TMA-07M capsule on a two-day trip to the ISS. While many improvements have been made to the Soyuz rockets and spacecraft since the first launch in 1966, the bottom line is that the Soyuz have become the world’s most used launch vehicles due to their consistent performance and relatively low cost.
Here, CSA astronaut Chris Hadfield talks about the Soyuz, briefly describing the strengths of the Russian technology that will once again take him and fellow Expedition 34/35 crew members to the ISS, where in March of next year he will become the first Canadian to take command of the Station.
“This is a safe and reliable and proven way to leave the Earth, and each successive Soyuz is different; each one has small changes. The role of the astronaut is to learn those small changes… and learn to apply them.”
– Canadian astronaut Chris Hadfield
The T version of the Soyuz craft began flying manned missions in 1980 and in 1986 the TM versions were transporting crews to Mir. The TMA upgrade addressed previous astronaut/cosmonaut height restrictions and permits the Soyuz to be used as a lifeboat for ISS crews, if necessary.

Canadian astronaut Chris Hadfield is scheduled to launch on Decemer 19 with crewmates Tom Marshburn and Roman Romanenko on a Soyuz rocket, heading for a long-duration 5-month mission on board the International Space Station. We’re taking a look back at his 2-plus years of training for this mission, which Hadfield shared via Twitter and Facebook, letting the public get an inside look at what it takes to prepare for a long-duration spaceflight.
The movie “The Right Stuff” depicted the grueling array of medical tests the early astronauts had to undergo in order to determine if they had… well, the right stuff to go into space. Now, more than 50 years later, with scientists and the medical community knowing quite a bit more about how the human body reacts to micro-gravity, the pre-flight medical procedures aren’t quite as intrusive. But astronaut Chris Hadfield says it is still part of being an astronaut.
“They do a nice job of telling how hard it is going to be, how invasive,” he said in an interview with Universe Today, “but none of that matters when it’s time to go to bed at night, when you’ve got six different probes stuck in you or a loud machine next to you, and you know you you’re not going to get a good night’s sleep.”
“Whether you are flying a spaceship or a T-38, it is good to be prepared,” Hadfield said, along with posting this image via Twitter.
Another part of medical training is having a forced special diet where “you have to document everything you eat, evaluating what happens at the other end,” Hadfield explained, “and they try to be as good and non-invasive as they can, but by its very nature it is invasive, and that’s the way it is.”
Hadfield said he knew about this going into the job. “It is absolutely part of the business so it is OK,” he said.
Hadfield participating in the VC Reflex test, an experiment for orthostatic hypotension, or dizzyness from low blood pressure, one of the most common physical complications of spaceflight. “Space Science: applying electricity behind the ears affects balance and thus blood pressure regulation,” Hadfield said.
Not only are there pre-flight medical tests and procedures, but all space station crew members undergo continual medical tests and evaluations during their time in orbit, becoming test subjects for various experiments as well as keeping tabs on their health while in space.
“We do regular urine, saliva collection and blood draws. We have to be able to take blood from each other or yourself. If you’ve never taken blood from yourself…” Hadfield said, letting the sentence trail off. Fun? Not so much.

Thankfully, the astronauts don’t always have to poke themselves. “We have volunteers come in all the time and let me stick them with a needle so I can get good at drawing blood,” Hadfield said, “and we do a lot of ultrasounds – carotid artery and cardiac ultrasounds. We need to identify any changes that take place in the heart after extended zero-g. This is all very important for going beyond Earth orbit; we need to understand those changes.”

Not only do the crew have to do medical tests on themselves, but they have to be prepared for any medical emergency, since there usually isn’t a dedicated medical doctor on the space station. However, Hadfield considers himself lucky: crewmate Marshburn is a medical doctor.
“There are various ways to get ill on board – some natural, like appendicitis, stroke, — or you could be in an accident.” Hadfield said, “Someone could bang their head coming around a corner, get pinched between equipment, get the bends coming in from a spacewalk, or be exposed to poisonous gas. Various things can happen.”
“We have full-911 capability on board,” Hadfield continued. “We can react, we can strap someone down, get them on oxygen, inject them with things to get their heart going again, or use defibrillators. We need to know how to intubate people and give them forced breathing. We need to know how to react.”
Medical training includes practicing emergency medical procedures such as stitches.
They have small pharmacy on board, and need to know a lot of procedures. “Of course we always have medical help on-call from the ground, but you could easily have to deal with a burn or something in an eye, so I’ve trained working in an emergency room at a hospital in Houston,” Hadfield said, doing things from making a quick diagnosis to inserting catheters or IVs, or sewing stitches on wounds “ so I can get comfortable doing those things to the human body.”
Astronauts on the ISS practicing CPR: “How do you give CPR without gravity to hold you down? Like this!,” Tweeted Hadfield.
