On this day, February 3, 1984, the Space Shuttle Challenger was launched on mission STS-41-B. This mission was significant for deploying two communications satellites and marking a major milestone in spaceflight history.
During STS-41-B, astronauts Bruce McCandless and Robert L. Stewart became the first humans to perform an untethered spacewalk using the Manned Maneuvering Unit (MMU), allowing them to move freely in space without being connected to the shuttle. This breakthrough demonstrated the potential for astronauts to conduct repairs and retrieve satellites in orbit.
Fun fact: The STS-41-B mission was the first time NASA successfully landed a space shuttle at the Kennedy Space Center in Florida, rather than Edwards Air Force Base in California.
Trivia question: What was the name of the first astronaut to perform an untethered spacewalk using the MMU during STS-41-B?
