Apollo was NASA's third human spaceflight program and the first to put people on the Moon, specifically with its 11th mission. Launched on July 16, 1969, astronauts Neil Armstrong and Buzz Aldrin landed on the lunar surface four days later, while Michael Collins remained in orbit, with Armstrong the first to lay foot on the sandy surface. "That's one small step for man," Armstrong said, one giant leap for mankind.

 

The "Baseball History" set includes the first launch of Space Shuttle Columbia STS-1 on April 2, 1981. The first space shuttle mission carried Commander John Young and pilot Robert Crippen. STS-1 launched exactly 20 years after the first spaceflight by Yuri Gagarin in 1961.

Columbia flew 28 missions, with the first and last making international headlines. On April 2, 1981, Columbia named after the American river – launched as the first reusable spacecraft. Propelled by two solid rocket boosters, the Orbiter Vehicle circled Earth 37 times before landing on a runway two days later. During a mission in 2003, Columbia disintegrated upon re-entry, and all seven astronauts aboard died.
