A huge new exhibit at the Kennedy Space Center in Florida showcases the pioneers of the past five decades who have blazed a trail into space. The “Heroes and Legends” exhibit opened this past week at the KSC Visitor Complex, honoring those who have been to orbit and changed our understanding of our place in the universe.

More than 25 U.S. astronauts were on hand for the event, including Buzz Aldrin and Jim Lovell. Nov. 11 marked the 50th anniversary of the Gemini 12 mission, which Aldrin and Lovell flew on.

“The new Hall of Fame is spectacular and a great addition to the Kennedy Space Center Visitors complex,” Al Worden, the Command Module Pilot on Apollo 15 told SpaceFlight Insider. “It will stand with the Saturn V Center and the Atlantis display as examples of what a nation can do when challenged. Absolutely worth the trip to see our heroes and legends on display.”

KSC said in a statement that it held the event on Veterans Day to honor military heroes, including the man astronauts who also served in the military.

“Relive the thrills and dangers of America’s earliest space missions and embark on an awe-inspiring journey designed to spark thought about how humans define a hero,” KSC states on its website. “Experience the dawn of the space age with astronaut pioneers through a mix of 4D multisensory theater and actual artifacts including a Redstone rocket suspended overhead along with the Sigma 7 capsule and a unique close-up look at the Gemini 9 capsule.
