Real spacewalk footage from astronaut Garrett Reisman gives you a wild reminder of what’s happening just above our heads.He previously worked with SpaceX, later becoming a professor of astronautical engineering at USC, and still advises the company.Watching this kind of footage really puts things in perspective, spacewalks look way more intense than most things on Earth…even deep sea diving.And somehow people still argue the Earth is flat 😅Writer: Lynn
