When astronaut Scott Kelly embarks on a one-year space station stint next spring, his twin brother will be offering more than his usual moral support.

A Russian rocket carrying a three-man crew to the International Space Station has blasted off from the Baikonur cosmodrome in Kazakhstan.
The Soyuz booster rocket lifted off as scheduled at 1:57 a.m. Thursday (1957GMT Wednesday) and soared into the darkness over the Central Asian steppe.
The crew — NASA's Reid Wiseman, Russian cosmonaut Max Surayev and German Alexander Gerst of the European Space Agency — are set to dock at the station less than six hours later. They are scheduled to stay in orbit for six months.
