Childrens book about spaceships

[antdunn007]

Bearing in mind that this was about 15 years ago, I once read a set of books at primary school about a a group of spacemen (it was kind of Star Trek, Star Wars, and Sharship Troopers all rolled into one). I vaguely remember their being different colours for each series. Red, Blue, green i think and I'm 90% certain that one of the episodes was called "The Troggs" or something like that. Vague i know, but if anyone knows the answer, i would be very grateful.
