The Apollo program considered many spacesuit designs, including some covered in plates of hard plastic, before settling on one design. This video by SciFri cleverly edits videos of astronauts testing the range of motion in different hard suit designs so that they appear to dance.
Of the suit he wore on the moon, Neil Armstrong wrote, “it was tough, reliable, and almost cuddly.” But that cuddly suit, made by the company Playtex, had some stiff competition (literally) from rival rigid, metal designs. This video features archival NASA footage of mobility tests for several spacesuit prototypes. Music is from the band One Ring Zero’s album “Planets”.
