Bruce McCandless
Bruce Edward McCandless II (1937–2017) was an American nasa astronaut and naval aviator, best known for performing the first untethered spacewalk in history.
Key Achievements
- First Untethered Spacewalk: On February 7, 1984, during the STS-41-B mission, McCandless used the Manned Maneuvering Unit (MMU) to drift up to 320 feet (98 meters) away from the Space Shuttle Challenger, marking the first time a human traveled in space without a physical connection to a spacecraft.
- Space Shuttle Missions: Flew on two Space Shuttle missions: STS-41-B (1984) and STS-51-C (1985).
Equipment and Technology
- Extravehicular Activity (EVA) Suit: McCandless’s historic maneuver highlighted the critical role of advanced Space Suit Materials and Technology for Extreme Space Protection in ensuring astronaut survival in the vacuum of space. The suit provided life support, thermal regulation, and pressure containment necessary for extended exposure to the extreme environment of outer space.
- Manned Maneuvering Unit (MMU): A jetpack-like device worn on the back of the space suit, allowing astronauts to maneuver freely in space.
