Hi there! First, the variable spaceship is already declared. You just need to create an instance of the class, so there's no reason to have Spaceship spaceship. You're supposed to be sending in the string "FIREFLY", but right now, you're not sending in anything to the constructor. Try including the string inside the parentheses where you make your new object. Also, the last function in your code (the one you added yourself) is not required by the challenge.

Hope these hints help, but let me know if you're still stuck! :sparkles:
