Spacesuit helps astronauts in various ways. Spacewalking astronauts face a wide variety of temperatures. In Earth orbit, conditions can be as cold as minus 250°C. In the sunlight, they can be as hot as 250°C. It protects astronauts from those extreme temperatures. Just like their special suits, astronauts have to wear specially designed shoes that help them to take a spacewalk without tripping over or hurting themselves.

MIT's research!

As shown in the video, moonwalks might look bouncy/peaceful, but cumbersome space suits had Apollo astronauts tripping and falling all over the place. So to make sure that doesn't happen, Alison Gibson, a graduate researcher at MIT's Man Vehicle Lab, is testing some newfangled space boots.

But how do you design a system that lets astronauts keep their heads up?

Gibson collected motion capture data from 16 participants who strapped on the prototypes, and those tests suggest people spend significantly less time heads-down while wearing the boots as shown in the video below.
Oh, and they fall less, too!
