I am looking for a young adult (probably actually middle grade) book I read when I was younger. I just remember bits and pieces–it was about a girl who lived in San Francisco, and she was interested in the first female astronaut,. She uses her whole name: Valentina Vladimirovna Nikolaeva Tereshkova (which is why I know it by heart even 20ish years later). The only other thing I really remember is the protagonist wasn’t Asian but would go to a little Chinese cafe or bakery after school to get a snack. The book would sprinkle in a few Spanish and Chinese words (it’s where I learned what shumai were) and would translate them in a footnote.

I remember the cover being bright and busy–orange and pink, with a lot of design on it, and I think the book was fairly thick, probably 200 pages. Does this ring any bells?
