Mark Kelly, speaks to guests after his induction into the Astronaut Hall of Fame (AHOF) by NASA Deputy Administrator Pam Melroy, during a ceremony inside the Space Shuttle Atlantis attraction at NASA's Kennedy Space Center Visitor Complex in Florida on May 6, 2023. Also inducted in the AHOF Class of 2023 was retired astronaut Roy D. Bridges Jr. Inductees into the Hall of Fame are selected by a committee of Hall of Fame astronauts, former NASA officials, flight directors, historians and journalists. The process is administered by the Astronaut Scholarship Foundation. To be eligible, an astronaut must have made his or her first flight at least 17 years before the induction. Candidates must be a U.S. citizen and a NASA-trained commander, pilot, or mission specialist who has orbited the earth at least once. Including Bridges and Kelly, 107 astronauts have been inducted into the AHOF.
