NASA astronaut and Expedition 48 Commander Jeff Williams returned to Earth recently after his fourth mission aboard the International Space Station
Williams now has a cumulative 534 days in space, the most of any NASA astronaut ever.
“No other U.S. astronaut has Jeff’s time and experience aboard the International Space Station. From his first flight in 2000, when the station was still under construction, to present day where the focus is science, technology development and fostering commercialization. Jeff even helped prepare the space station for future dockings of commercial spacecraft under NASA’s Commercial Crew Program,” said Kirk Shireman, ISS Program manager at NASA’s Johnson Space Center in Houston. “We’re incredibly proud of what Jeff has accomplished off the Earth for the Earth.”
In 2010, Williams was part of another NASA milestone as the commander of Expedition 22. During that mission, he became the first astronaut to interact live with NASA followers from space via social media.
