Mission-specific training
Training
When the Canadian Space Agency (CSA) selects new candidates, the aspiring astronauts must first go back to school!
All recruits must follow a three-phase training program:
- Astronauts' basic training
- Ongoing training and tasks while awaiting a mission
- Mission-specific training
Finally, trained astronauts who have received an assignment may go to space to participate in a mission.
When they are assigned to a mission onboard the International Space Station (ISS), astronauts take a training program of approximately two years, custom-made for their mission.
Most of their training takes place at NASA's Johnson Space Center, using simulators and the virtual reality laboratory. The astronauts also have to travel to Europe, Russia and Japan.
Spacewalks: training safely

One of the biggest challenges of astronaut training is learning how to perform tasks in low-gravity environments.
As a result, before being able to go out into space from the ISS, astronauts have the opportunity to train in different environments:
- in virtual reality
- in a pool
NASA has a Neutral Buoyancy Laboratory at the Johnson Space Center in Houston. This site is equipped with a large 12-metre deep pool that is used to simulate weightlessness.
All members of the same expedition are trained to walk in space in order to be able to replace a colleague, if need be.

The pool is big enough to submerge full-scale models of components of the ISS! The astronauts can therefore practise carrying out spacewalks.
Knowing the Soyuz capsule inside out

The astronauts must go to Star City, Russia, to learn all about the Soyuz spacecraft. Currently, Soyuz is the only vehicle capable of transporting humans between Earth and the ISS. It is also used as the Station's rescue vessel in the event of an emergency.
In order to take their seat aboard a Soyuz, the astronauts have to undergo extremely rigorous training. They must master:
- the technical aspects of the spacecraft
- Russian
Then, according to their role on the capsule, the astronauts must learn their tasks during the launch, docking and landing of the Soyuz.

Operating Canadarm2

Operating Canadarm2 is among the most delicate activities of a mission onboard the ISS.
The astronauts must be able to carry out two essential tasks:
- catch and dock unmanned capsules containing supplies such as:
- food,
- clothing,
- spare parts,
- scientific experiments,
- research material;
- manipulate Canadarm2 in order to move astronauts on spacewalks.
Thankfully, the astronauts can count on the CSA's robotics training centre for adequate training!
Learning about the ISS

Using the ISS modules
Before travelling to the ISS, the astronauts must know all of the ISS modules like the back of their hand. All ISS partners have full-scale models of their respective modules to train the astronauts.
Plus, during their stay in orbit, the astronauts must conduct scientific experiments. In order to do so, they must learn to use the scientific modules and familiarize themselves with their different systems, namely:
- data management,
- electrical power distribution,
- environmental control,
- thermal control,
- communications.
Handling emergencies
The crews of the ISS missions must meet in Houston to carry out safety training and simulation activities. The astronauts must be ready to handle the dangers associated with space flight:
- depressurization,
- fires,
- air contamination.
CSA astronaut Chris Hadfield and his colleagues Roman Romanenko and Tom Marshburn take part in simulated emergencies conducted in an ISS mock-up at NASA's Johnson Space Center in Houston, Texas.
