Book about a teenage girl who ends up on the moon

I read it in the early to mid 2010s. All I remember is that it was already a few (maybe more) years old. Think those mass produced books from the 90s, but I don't know if that's actually when I came out. The main character is a teen girl. In one of the opening scenes, she is talking to her friends at lunch when a robot lunch monitor reprimands one of them for something. I also remember that she does a bunch of testing before getting it sent to what I believe is the moon, but could have been another planet. I know there is a guy that she has a little bit of a romance with as well.
