The astronauts set up to the first manned space mission since an unprecedented accident on Russia Soyuz, taking captive security concerns Sunday, saying they were ready to risk.
Oleg Kononenko de Roscosmos, NASA's Anne McClain and David Saint-Jacques from the Canadian Space Agency will launch Baikonur's International Space Station (ISS) in Kazakhstan on Monday.
They will go to the ISS after a Soyuz rocket carrying Aleksey Ovchinin from Russia and the American astronaut Nick Hago failed on October 11 only minutes after an explosion.
The couple escaped unharmed, but the failed launch was the first such event in Russia's post-Soviet history and a new disadvantage for the country's former proud industry.
The crew to the ISS dismissed some possible concerns about their security.
"Risk is part of our profession," commander of crew Oleg Kononenko told a news conference at Baikonur, adding them "absolutely" entrusted teams preparing them for the flight.
"We are psychologically and technically ready for an explosion and any situation that God forbids, can happen on board," said the 54-year-old.
Anne McClain, a 39-year-old military driver, hit a similar note.
"We're very happy for that," she said.
Saint Jacques of Canada added that the Soyuz spacecraft was "incredibly safe," noticing that it was "really tranquil" to testify on October aborted the launch of Baikonur.
The accident highlighted the "smart design of the Soyuz and the incredible work that the search and salvation of people here on the ground is ready to do every launch," said the 48 year old.
Russia said last month the launch of Soyuz's rocket failed because of a sensor that was damaged during the meeting at the Baumium Cosmetic. But employees insisted that the spacecraft remains reliable.
Saint Jacques will be the first Canadian astronaut to visit the space station since Chris Hadfield, who recorded a version of David Bowie's Classic Oddity classic on the ISS in 2013.
The governor of Canada in general and former astronaut Julie Payette is expected among dignitaries to watch Monday's launch.
From the trio set to reach the ISS six hours after the explosion, both Saint-Jacques and McClain will fly for the first time. Kononenko begins his fourth mission to add stunning 533 days in the space.
NASA's McClain was deployed to Iraq and represented the United States national rugby team in the past.
She said that training at a spaceship was similar to rugby, because it requires "crack, difficulty, mental focus and more."
