Why are all space crafts called Apollo?

Not all spacecraft are called Apollo; "Apollo" specifically refers to the series of missions conducted by NASA from 1961 to 1972 aimed at landing humans on the Moon. The name Apollo was chosen to symbolize the god of light and knowledge, reflecting the ambitious goals of the program. Other spacecraft, such as the Space Shuttle, Voyager, and Mars rovers, have different names based on their unique missions and designs. The Apollo program is iconic, particularly for its historic Moon landings, which is why the name is often associated with space exploration.
