Astronauts Breeze Through Spacewalk to Boost Space Station Power Grid

Two astronauts embarked on a spacewalk outside the International Space Station (ISS) today to complete an upgrade to the station's power supply. NASA astronaut and space station commander Shane Kimbrough set out with French astronaut Thomas Pesquet of the European Space Agency this morning (Jan. 13) at 6:22 a.m. EST (1122 GMT), nearly 40 minutes ahead of schedule. From the speed and efficiency of his work today, it was hard to tell that this was Pesquet's first spacewalk.
