I have to agree with some fellow reviewers - this is a 5 star book for what it is. It's a simple exploration of the life of an astronaut, from a girl's dream to the reality of the application and training progress, through the whole of a shuttle launch, the practicalities of eating, washing, sleeping and yes using the potty in space. The servicing of a telescope to fulfil her job and why that is important.
Love that this is a girl's story for my daughter to relate to.
Love that it explores the aspects of space life in a simple straightforward way but still uses many technical terms for the budding scientist!
