Aiming for the stars
The Soyuz will head off on its journey from Baikonur cosmodrome in Kazakhstan on Wednesday.
Its international crew consists of Dmitry Kondtrayev from Russia, who is the commander of the mission, American astronaut Catherine Coleman and Italian astronaut Paolo Nespoli.
The three will carry out experiments and take seasonal gifts to those currently onboard the ISS.
The rocket arrived at Baikonur in three different parts and the process of putting it together is extremely intricate.
“Preparations take a long time. It can take from five days to two weeks to unload all the separate parts of the rocket and assemble them," says Nikolay Zaglada, the Assembly team head. “After the rocket is assembled, it has to undergo a series of tests. Every team looks through some part of the rocket – the engine, the electronics.”
TMA-20 is regarded as the safest way of getting people into space. Former astronauts came to see the rocket being raised and some still get a tingle, remembering what launching was like from Baikonur.
“It's always fun to see a vehicle getting ready to launch, whether be it a shuttle or a Soyuz,“ recalls NASA astronaut Peggy Whitsin. “It does take you back to the opportunity that I had which was to be actually able to step onto it, and it's an amazing experience."
