You can glue it back on, but don't use rubber cement. Most model glues will work fine and even better is super glue!
if it is a plastic model kit you can use super glue, but not wood glue.
If you use an all purpose glue or synthetic glue it should be fine.
Most model rockets do not come with glue. It also depends on which type you are purchasing and where you are purchasing it from. Try calling a store or company and asking if their model rockets come with the glue.
