Although the date of the first space shuttle launch occurred on the 20th anniversary
since Yuri Gargarin's first man in space flight, it was not planned.
The first STS-1 launch attempt was canceled due to technical difficulties. It was moved to April 12 by NASA.
Launching any rocket, especially a new one, is not without its challenges.
NASA is currently facing the same problems as it attempts to fly the Space Launch System and Orion spacecraft in a test flight, the Artemis 1 mission.
This time, however, the goal is not limited to low-Earth orbit. Artemis's goal is to make the moon a permanent place.
