After a gap of more than a year, NASA successfully resumed spacewalks outside the International Space Station on Thursday. NASA astronauts Nick Hague and Suni Williams, dressed in pressurized NASA spacesuits, moved through the Quest airlock and into the vacuum of space.

This event, known as US Spacewalk 91, is Williams' first in 12 years and her eighth overall, while for Hague, it's his fourth venture outside the ISS.
