This book is OK. However, there is a huge problem with it; as opposed to other survival novels Ive read before such as Hatchet or any Gary Paulsen book, My Side of the Mountain, The Mysterious Island, etc, (it's one of my favorite genres), this book lacks a detailed account of most or all of the available supplies and equipment from the onset of the ordeal. 
 This is an extremely important step in any survival book as it sets the reader and the protagonist at a specific stage of danger and survival need. We have instead a protagonist whose name I've forgotten who has a lot of science stuff. There's no account of what he has, how much of it, or what it does. Instead of that we get those details as the story progresses. This basically works out as a series of tiny Deus ex machinas. "Oh I need a Macguffin A. Oh I've just remembered 'they' provided me with a Padoodle! Here is a Padoodle which I can distill into a Macguffin A!" 
 In a better set up survival story: "I desperately need a Macguffin A! I must find one. Or make one. From my supplies I already had from before I might be able to make one but I'll need to hunt for a Padoodle, or something similar to create one." 
 Basically the hunt is missing, and also not knowing what the Martian has in his pocket makes it seem like his pocket is bottomless. 
 What should be possibly the most horrifying ordeal known to man is instead just a tiny little mishap. Will continue after I've completed the novel.
