This book is filled with facts but lacks direction or purpose.
For instance, do you understand the notation: "6.3 kPa"?
If you do understand this notation, then you most probably know all the facts quoted in this book already and will find it somewhat tedious. If you don't understand this notation, then this book uses it but does little to explain exactly what it means. Either way, it is not a good place to be in.
There are some typo errors and the formatting definitely needs improving.
Pictures with annotations embedded were used, but, even at the maximum resolution, the annotations were unreadable.
What pictures there where seemed to have been sourced from the NASA website. I would be incline to suggest that you hop over to the NASA website yourself and see them there first hand and as intended.
For me, there seemed no logical progression as you go from one chapter to the next. Just, here is another topic and here are some facts. There was no effort made to interweave the subject matter and to show how the various topics were interrelated - it is all a bit disjointed.
It takes about 10 minutes to read so, if it is not available on a free download, I would give it a miss. The NASA website at [...] is much more informative and cohesive.
