Two Russian cosmonauts have spent more than seven hours outside the International Space Station in an unexpectedly long spacewalk.
Reports say the two ran into problems with their first task -- installing a new communications antenna.
It was the first spacewalk for Alexander Skvortsov and Oleg Artemyev, who, along with U.S. commander Steve Swanson, have been aboard the orbital outpost for almost three months.
They were joined on May 28 by three more crew members, including NASA astronaut Reid Wiseman, who has been documenting his time in space on Twitter.
