Two Russian cosmonauts will take a 7-hour spacewalk on Thursday to install scientific equipment and a camera onto the outside of the International Space Station. Commander Commander Oleg Kotov and Flight Engineer Sergey Ryazanskiy begin at about 8 a.m., Eastern and NASA will livestream the spacewalk, which you can watch below. 

This is the 11th spacewalk on the station this year, but it's also the third one in just the last week. Flight Engineers Rick Mastracchio and Mike Hopkins took a pair of emergency space walks last Saturday and again on Tuesday, Christmas Eve, in order to repair a faulty valve system
