Walking in Space
Explanation:
Pictured
above is the
first
american astronaut to walk in space:
Edward
White. White is seen floating outside the
Gemini 4 capsule in
1965. The term "spacewalk" is deceiving since astronauts do not actually
walk - they float - usually without their feet touching anything solid.
White was connected to the spaceship only by a thick tether. He carried a
Hand-Held Self-Maneuvering Unit which expelled gas allowing him to move
around. A maneuvering device is necessary in the
free-fall
of space since there is nothing (besides the spacecraft) to push off of to
guide movements.
