From noon-4 p.m. Sunday, visitors can learn about the "hopping" spacecraft being developed by the Lehigh University Hopper Project team that could replace NASA's "rover" crafts; meet MoonMan, the center's Space mascot and explore "Space: A Journey to Our Future," the summer exhibit that was created in cooperation with NASA.

Former astronaut Terry Hart, who orbited the Earth on the Challenger space shuttle in 1984 and is now a professor of mechanical engineering at Lehigh University, will talk about his experiences and answer questions at 1:30 p.m.

Former astronaut Guion Bluford, who flew on four space flights and was the first African-American in space, will talk and answer questions via Skype at 2:30 p.m. Bluford, a Philadelphia native orbited the Earth on the Challenger space shuttle in 1983 and 1985, and on the Discovery space shuttle in 1991 and 1992.

Video of news footage from the Apollo 11 moon landing on July 20, 1969, will be shown at 1 p.m. and 4:30 p.m.

"Space," which drew 3.8 million to Smithsonian National Air and Space Museum, features interactive exhibits and state-of-the-art projection and audio technology. It will be at the Allentown museum through Sept. 7.

Families can walk through a full-size space habitat and work pod and explore a future lunar base camp, ride a bicycle-powered centrifuge and experience the physiological challenges of space flight, touch rocks from the moon and Mars and see a wide range of artifacts from space flights.

Admission to the center is $19.95, adults; $16.95, 12 and under and seniors.
