is this sentence correct "What spacecraft do astraunots fly to moon in?"

[Avalon]

I´d say..."What do astronauts use to go to the moon?" or " How do astronauts get to the moon?" and I would accept answers like, spacecrafts,rockets,spaceships, space shuttles...but you surely must put the before moon, we have only one!
