AnswerClick to flip back
A
Mercury
💡 Explanation:
NASA initially wanted to use "Mercury" to refer to space travelers, but the name was already associated with other projects. They ultimately chose "astronaut" from Greek words meaning "star sailor." The other options (Venus, Moon) are celestial bodies, not proposed terms.
