Moonshot is a noun that refers to an extremely ambitious and innovative project.

Coming from two well-known English words, our word of the day is often used to describe a literal spacecraft trip to the moon, but it’s more commonly used in a metaphorical sense. Here’s an example of it:

Hector had great respect for my ambition to become a professional boxer. I’d always admired prizefighters. Of course, the fact that I’d never been in a fight in my life made the endeavor something of a moonshot.
