Astronauts complete first spacewalk of 2018

Astronauts spacewalked outside the International Space Station on Tuesday, January 23, marking the first spacewalk of 2018.
Expedition 54 Flight Engineers completed the first spacewalk of the year around 2:13 p.m. EST after making adjustments to International Space Station's big robotic arm. Astronauts Scott Tingle and Mark Vande Hei floated out of the station to replace what is known as a grappling device on the end of Canadarm2, NASA said.
This is Vande Hei's first spacewalk and the first time astronauts have ventured outside the station in 2018.
