I am looking for the title of a young adult novel from 1964-1966. It has a group of high school geniuses who build a rocket ship and travel to the moon. A few boys and one girl. It is NOT Heinlein's Rocket Ship Galileo, nor any book by Heinlein. It included a teleporter, masers, lasers and travel to the star Alpha Centauri in a teleporter mishap. The boy and girl transported to Alpha Centauri make it back to Earth 9 years later, time lagged because of the teleporter speed of light transmission time and meet up with another of the original crew, now 9 years older. The book ends with the survivors destroying their landing module on the moon using a laser from earth. I forget the reason why. I recall a title like Foxfire, or Firefox, but that doesn't turn up anything on Google.
