The three new crew of the orbiting outpost lifted off without a hitch on Monday, Dec. 3, from Kazakhstan.
Russia's state space corporation, Roscosmos, traced the failure to a damaged sensor and found that two other Soyuz rockets might have the same defect.
It was the first manned mission since a failed launch in October.
The launch of the Soyuz MS-11 spacecraft carrying Saint-Jacques, Anne McClain of NASA and Oleg Kononenko of the Russian space agency, Roscosmos, appeared to go exactly as planned, lifting off at precisely 6:31 a.m.
They're due to arrive at the ISS six hours after launch, and they'll board the station less than two hours after that.
The ship successfully launched into orbit.
A Soyuz rocket carrying Russian, American and Canadian astronauts took off from Kazakhstan and reached orbit today, the first manned mission since a failed launch in October.

The astronauts were the first sent to be sent to the space station since a crewed Soyuz launch was aborted in October after a booster rocket failed to separate properly, crippling the rocket.
"We are psychologically and technically prepared for blast-off and any situation which, God forbid, may occur on board".
"Every five-minute increment of our life is scheduled, and that will be the same for David also", he said at the space agency office. Roscosmos is the only organization that can ferry astronauts to the ISS so far.
In recent years Russia's debt-laden space industry has suffered a number of mishaps including the loss of cargo spacecraft and satellites. NASA has awarded multi-billion dollar contracts to SpaceX and Boeing as part of the space agency's Commercial Crew Program.
Monday's launch was needed to guarantee that the ISS was not left unmanned after the station's current crew returns to earth later this month.
Astronauts Serena Aunon-Chancellor, Russian Sergei Prokopyev and German Alexander Gerst are at the space station waiting for their arrival.
While that test flight may yet be delayed, NASA hopes that by the end of 2019 there will be a proven route to the ISS using rockets built by commercial space companies.
The trip to space - which had originally been scheduled for December 20 - had to be moved up to ensure that the ISS wouldn't be abandoned for the first time since crew arrived there on November 2, 2000.
