NASA video shows the first human to float freely in space

On February 7, 1984, NASA astronaut Bruce McCandless II made history by becoming the first human to float freely in space without a safety tether. During Space Shuttle Challenger's STS-41B mission, he piloted the Manned Maneuvering Unit (MMU), a nitrogen-powered backpack that carried him nearly 320 feet (98 meters) from the shuttle while orbiting Earth at 17,500 mph. His unforgettable solo spacewalk lasted 1 hour and 22 minutes, producing one of the most iconic images in spaceflight history (https://www.nasa.gov/history/photos-from-sts-41b/). As McCandless famously said, "It may have been one small step for Neil, but it's a heck of a big leap for me." Footage courtesy: NASA Video Editing by Starlust.org
