Two cosmonauts have completed the longest ever Russian spacewalk spending 8 hours and 13 minutes outside of their rocket to install a new communications antenna. Expedition 54 Commander Alexander Misurkin and Flight Engineer Anton Shkaplerov of the Russian space agency Roscosmos completed the spacewalk - making it the longest Russian spacewalk in history - breaking the previous record of 8 hours and 7 minutes.
