David Saint-Jacques' roles and responsibilities
While aboard the International Space Station (ISS), Canadian Space Agency (CSA) astronaut David Saint-Jacques will draw on all of the knowledge and skills he has acquired during his many years of training.
He will have various responsibilities to ensure smooth operations and safety on the ISS.
Acting as Soyuz co-pilot
On his journey to the ISS and on his way back home, will sit to the left of pilot and commander Oleg Kononenko in the Soyuz spacecraft.
As the Soyuz co-pilot, David will assist Oleg in commanding the vehicle, ready to take over completely should something prevent the commander from performing his functions.
Carrying out science experiments
The International Space Station is first and foremost a large orbiting research laboratory. Every day, dozens of science experiments are conducted on board.
Their purpose is to study the impact of weightlessness on the human body in order to protect the astronauts. The research also benefits various aspects of our everyday lives.
During his mission, David will conduct international and Canadian science experiments.
Going on spacewalks
Like all astronauts assigned to a space mission, David has obtained his qualification to conduct spacewalks, also called extravehicular activities.
David aced his virtual and practical training at NASA's Neutral Buoyancy Laboratory, making him fully qualified to perform spacewalks should the opportunity present itself.
David is trained to capture and dock visiting cargo ships using Canadarm2. He holds the highest level of qualification.
During his mission, he will be prepared to carry out cosmic catches when necessary.
SpaceX's Dragon and Orbital ATK's Cygnus are uncrewed resupply vehicles that play a key role in space missions. They carry a wide variety of materials, from spare parts, to science experiments, to necessities for the crew living aboard the station.
Once a doctor, always a doctor—even in space
David will act as crew medical officer during Expedition 58/59.
His years of practising medicine in small teams in Nunavik, a remote region, have prepared him well for a space mission.
As a crew medical officer, David is committed to the health and well-being of his crewmates, and he'll be ready to spring to action as required.
Knowing the Columbus Laboratory inside out
Crewmembers receive training on all of the ISS modules. They learn how to use the scientific equipment in every module and what to do in the event of an emergency.
There is always at least one crewmember trained as a specialist for each module.
David will serve as the specialist for the European Space Agency's Columbus Laboratory. That means he will take care of its maintenance, its repairs, and any issues that may arise.
