Charlie and the Great Glass Elevator

Charlie and the Great Glass Elevator by Roald Dahl

The sequel to Charlie and the Chocolate Factory takes the story on a science fiction trip. The glass elevator goes a bit too far and ends up in orbit. There it runs into the space hotel. At first they are seen as enemies to the US. After they scare off bad aliens, they are ready to be awarded a medal. There is also experience of specials substances that let people take years off their age or add years on. Alas, people take too many and find themselves babies - or multiple centuries old. The book seems a mishmash of interesting concepts, but other than the characters does not relate much to the previous book.
