This new launch schedule will help guarantee the continuity of world-class science and time-critical operations on the Space Station.
Saint-Jacques has trained for two years for this mission and during the last five months, he has served twice as part of a backup crew.
Saint-Jacques will bring a broad set of skills to the ISS.
As a fully trained spacewalker and robotic operator, he will provide critical capabilities during a period when multiple spacewalks and maintenance tasks are required.
As a medical doctor, Saint-Jacques will ensure the crew is cared for in their remote outpost.
