An all veteran crew from the U.S, Russian and Japanese space agencies is preparing for launch to the International Space Station Wednesday night with a very special payload aboard — an Olympic torch, part of a high-profile buildup to the 2014 Winter Games in Sochi, Russia.

The crew’s Soyuz spacecraft is slated to lift off at 11:14 p.m. EST from the Baikonur Cosmodrome in Kazakhstan. Russian cosmonaut Mikhail Tyurin, NASA astronaut Rick Mastracchio and Japan’s Koichi Wakata should reach the station about 5:30 a.m. on Thursday.

Their arrival marks a departure from the typical rotation of station crew members. Usually, half the six-member live-aboard crew returns back to Earth a couple of weeks before their replacements are launched. This time, however, Russia wants its returning crew members to bring the torch home, so the replacement crew/torch delivery team is arriving early.

Just bringing the Olympic torch to space isn’t enough. On Saturday, cosmonauts Oleg Kotov and Sergey Ryazanskiy, who have been aboard the station since Sept. 25, will make a spacewalk during which they will display and photograph the torch outside the outpost.

The next day, the torch will head back to Earth with returning crew members Fyodor Yurchikhin, Luca Parmitano and Karen Nyberg. The torch will be prominently featured during the opening ceremonies of the Olympic games in February.
