Nickelodeon Show- Kids in a spaceship- girl with rainbow hair...?

Does anyone remember maybe 10 years or so ago, a show where there were a bunch of teenagers on a space ship, and they all had superpowers? They weren't really super powers though, they were just aliens. I was young but I remember there was a girl with Rainbow hair, who's name was Catarina, and she had an imaginary/ invisible friend namd Suzie. Her super power was she could scream really loud. If anyone remembers the name please tell me, cause I remember I loved that show...
