The Science of Spacewalks: Humanity in Space

Part 2 of our Humanity in Space series deals with the science, technology, and history of the spacewalk. From the first-ever spacewalk in 1965 by Cosmonaut Alexei Leonov to the first American astronaut Ed White, spacewalks were all about getting out in space and giving it a show in the early days.
I try and walk through some fo the major milestones in spacewalks, while also learning about the science that goes into making a successful one.
Plus, dive deep into the training the astronauts go through before walking in space and hear from retired astronaut Nicole Stott about training for her spacewalk, and what it was actually like floating outside the ISS high above the Earth.
