"The spacesuit is the unsung hero of the space industry. It doesn't boast the massive thrust of a rocket, nor does it have the panache of a lunar lander. But the spacesuit is a marvel. It's a mini-spaceship in its own right, designed to protect the most iconic symbol of all: the astronaut. However, the spacesuit isn't without its flaws - just look at some of the funny outtakes from the Apollo landings. That's why it's evolved in the past few decades. With 11 layers of materials, the suit takes years to produce and costs millions of dollars. Each astronaut spends quality time with his or her suit before going into space, donning it for up to 10 hours per day during training. "

This NASA documentary celebrates 50 years of extravehicular activity (EVA) or spacewalks that began with the first two EVAs conducted by Russian Alexey Leonov in March 1965 and American astronaut Edward White in June 1965 . The documentary features interviews with NASA Administrator and astronaut, Charles Bolden, NASA Deputy Administrator and spacesuit designer, Dava Newman, as well as other astronauts, engineers, technicians, managers and luminaries of spacewalk history. They share their personal stories and thoughts that cover the full EVA experience-- from the early spacewalking experiences, to spacesuit manufacturing, to modern day spacewalks aboard the International Space Station as well as what the future holds for humans working on a tether in space. "Suit Up," is narrated by actor and fan of space exploration Jon Cryer. Cryer recently traveled to Star City, NASA Headquarters and the Johnson Space Center to film an upcoming Travel Channel documentary series.

However, a little known fact about this flight is what took place before it. Shepard sat in the rocket for five hours because of delays, and the astronaut really had to use the restroom.
