Apollo Astronauts are Minifigures that work for NASA's Apollo program. The Apollo Astronaut is from the Discovery theme. They are assigned different missions and are sometimes sent into space after vigorous training. Their missions include repairing systems that are damaged or outdated, landing on the Moon or collecting research. They only appeared in the set 10029 Lunar Lander.
He has the same head piece as several minifigures from the Exploriens theme.
