With a big interest in science and the universe, I wanted to do something related to space. At the same time, I wanted to honor the first American astronauts from different ethnic groups that went to space. I have seen stamps related to space, but they are usually about Apollo or moon landing. In the history of humanity going to the moon, there's more than just picking a moon rock and coming back to Earth. I wanted to honor diversity in space.
Guion S. Bluford, the first African-American astronaut, completed over 688 hours in space. On John Herrington’s first voyage in 2002, he became the first Native American astronaut. Franklin Chang-Díaz became the first American astronaut of Hispanic descent and completed over 1600 hours in space. Ellison S. Onizuka was the first Asian-American astronaut and the first Hawaiian in space.
