    in 1961, NASA astronaut Alan Shepard became the first American to fly in space aboard his Mercury capsule named Freedom 7. How have NASA astronauts inspired you to follow your dreams?

    A close-up of astronaut Alan B. Shepard Jr. in his space suit with his helmet on inside the Mercury capsule. He is undergoing a flight simulation test with the capsule mated to the Redstone booster. This will be the first attempt to put a man into space by the U.S. aboard a Mercury spacecraft, launched atop a Redstone rocket.
    Expedition 67 Flight Engineers Kayla Barron and Jessica Watkins, both from NASA, and Samantha Cristoforetti from ESA (European Space Agency) are pictured checking out systems inside the International Space Station's Kibo laboratory module.
    On June 3, 1965, NASA astronaut Ed White stepped out of his Gemini capsule and into space for the first American spacewalk. Attached by only a 23 foot tether and 25 foot umbilical, White floated in space for roughly 20 minutes. Circling the Earth at a speed of 17,000 miles per hour, he traveled 6,500 miles.
    Astronaut Tom Marshburn completed his first spaceflight in July 2009. He launched to the International Space Station as a Flight Engineer in December 2012. While onboard the station, he logged more than 146 days in space and 5 hours and 30 minutes of spacewalk time in an emergency spacewalk to replace a leaking ammonia pump. He is currently serving as pilot of the NASA SpaceX Crew-3 mission to the ISS, which launched on November 10, 2021 and is set for splashdown on May 6, 2022 at 12:43am ET (4:43 UTC). The Crew-3 astronauts spent 177 days in orbit.
