So many people live within unhappy circumstances and yet will not take the initiative to change their situation because they are conditioned to a life of security, conformity, and conservatism, all of which may appear to give one peace of mind, but in reality nothing is more damaging to the adventurous spirit within a man than a secure future. The very basic core of a man’s living spirit is his passion for adventure. The joy of life comes from our encounters with new experiences, and hence there is no greater joy than to have an endlessly changing horizon, for each day to have a new and different sun.
In this Feb. 7, 1984 photograph taken by his fellow crewmembers
aboard the Earth-orbiting Space Shuttle Challenger on the STS-41B
mission, NASA astronaut Bruce McCandless II approaches his maximum
distance from the vehicle. McCandless became the first astronaut to
maneuver about in space untethered, during this first “field” tryout of a
nitrogen-propelled, hand-controlled backpack device called the Manned
Maneuvering Unit (MMU).
For 50 years, NASA has been “suiting up” for spacewalking. The first American to conduct a spacewalk, astronaut Edward H. White II, floated into the vastness of space on the Gemini IV mission on June 3, 1965. For more than 20 minutes,
White maneuvered himself around the Gemini spacecraft as it traveled
from over Hawaii to the Gulf of Mexico–making his orbital stroll 6,500
miles long. At the end of the 20-minute spacewalk, White was exuberant.
“This is the greatest experience,” he said. “It’s just tremendous.”
