more than 50 years. U.S. Astronaut Hall of Fame The United States Astronaut Hall of Fame, located inside the Heroes & Legends building, is included with visitor complex daily admission. The Hall of Fame was previously owned and operated by the U.S. Space Camp Foundation, but was purchased at auction by Delaware North Park Services in September 2002 on behalf of NASA. The building was renamed the ATX Center and houses educational programs including Camp Kennedy Space Center and the Astronaut Training Experience. Rocket Garden The Rocket Garden is located inside the front entrance, beyond Heroes & Legends.It is an outdoor display of historic rockets that put Americans and satellites in space. Visitors can walk up to and around the base of the rockets. All of the rockets in the garden are legitimate rockets with the exception of the Mercury-Atlas, which is a re-creation replica. The Mercury-Redstone, Mercury-Atlas, and Titan II rockets launched astronauts and the Juno I, Juno II, Thor-Delta, and Atlas-Agena rockets launched satellites from Cape Canaveral. These are mounted upright whereas the largest rocket, a Saturn IB, is mounted on its side. Saturn IB rockets launched Apollo Command/Service Modules into Earth orbit for Apollo, Skylab, and the Apollo–Soyuz Test Project. The Saturn IB was restored in 2018. In March 2021, a Delta II launch vehicle was added to the Rocket Garden. The Juno I on display is painted with serial number "UE", a reference to the vehicle that launched the first U.S. satellite, Explorer 1. A Juno II launched the first American probe to escape Earth's gravity and fly past the Moon. Atlas-Agena rockets launched early probes to the Moon, Venus, and Mars, as well as the Agena target vehicles used in rendezvous and docking by Gemini spacecraft — a necessary technique for the following Apollo missions. The Thor-Delta was one of the most reliable and frequently used launch vehicles. The Titan II on display is a refurbished Air Force ICBM with a replica Gemini spacecraft, painted to resemble the Gemini 3 booster. It was rescued from the Arizona Boneyard and erected in 2010 to replace a deteriorating mockup composed of two first stages which had been on display for more than 20 years. The Saturn IB on display is SA-209 which was designated for a possible Skylab Rescue mission. The garden also features mock-ups of capsules from the Mercury, Gemini, and Apollo programs that visitors can
