A Soyuz rocket carrying an American astronaut and two Russian cosmonauts roared into space today on the first-ever "express" flight to the International Space Station.

The rocket launched NASA astronautChris Cassidyand Russian cosmonauts Alexander Misurkin and Pavel Vinogradov into orbit at 4:43 p.m. EDT(2043 GMT) from the Baikonur Cosmodrome in Kazakhstan, where the local time was early Friday. The crew's Soyuz TMA-08M spacecraft is expected to make history when it arrives at the space station later tonight.

The Soyuz crew plans to dock at the space station's Poisk module tonight at 10:32 pm EDT (0232 GMT Friday). You can watch the space docking live on SPACE.com here.

Until today, Soyuz and NASA shuttle trips to the space station typically took at least two days, but Cassidy, Misurkin and Vinogradov are due toarrive in just six hours, after making only four orbits of Earth. Some NASA officials have dubbed the flight profile, the "express" flight to the International Space Station.

"I think this is a very good thing that we are decreasing the time that it takes for crews to reach the International Space Station," Vinogradov said in a pre-launch interview. "I'm confident that both in Russia and in the United States we have excellent teams that are supporting us." [Launch Photos: Soyuz Rocket's 'Express' Flight to Station]

The quick trip to the space station has been made before by unmanned cargo spacecraft, but never by a crew. Mission managers say its benefits include less time spent in a cramped space by the crew, and a savings on expenses related to the personnel needed in Mission Control when Soyuz is flying.

Once there, they will join the existing station residents commander Chris Hadfield of Canada, Russian cosmonaut Roman Romanenko, and NASA astronaut Tom Marshburn on the station'sExpedition 35 mission. The newcomers are due to stay in space for about six months.

"It's shaping up to be a very dynamic and a very busy expedition," Cassidy said during a pre-launch interview. "We welcome that that makes us feel very rewarded and high job satisfaction. When you can deliver for people that have worked hard to produce all of those activities on the ground, that's very satisfying," he said of the ability to fulfill the goals of the Mission Control team.

Cassidy and Vinogradov are both spaceflight veterans: The former flew on the STS-127 space shuttle mission in 2009, while Vinogradov visited the Russian Mir space station in 1997 and theInternational Space Stationin 2006. Misurkin, a spaceflight rookie, is making his first journey to orbit.

"I'm just really excited and looking forward to this flight," he said in a preflight interview. "I think it would be a great experience for me and the biggest thing in my whole life."
