Making Starships and Stargates: The Science of Interstellar Transport and Absurdly Benign Wormholes by James F. Woodward

The topic of travelling through wormholes and stargates and travelling quickly to interstellar distances had probably interested anyone who has ever watched Sci-fi series or movies where those concepts are used. Because the topic is so widely used in pop culture I feel like there are tens of books that deal with starships etc. 

What makes this book special? The author looks into published scientific papers in those topics on the possibility of travel at light-speed using different methods, looking into the physics and mathematics there etc. How might it be possible? Which laws of nature seem to forbid such travel? You can read all about that and much more in this book. 

The book is highly technical, very detailed and you do need some higher maths and  quite a lot of motivation to work through it. 
If you find though that it's a little too difficult, then the book also has excellent bibliography which can guide you either in the more popular books direction or to some more technical books.

I found that it was interesting, well written and followed a logical structure  so you see how the different principles and concepts are all necessary for it.

NASA's latest New Frontiers mission, OSIRIS-REx, will venture to a near-Earth asteroid to discover clues about the unique resources asteroids hold, processes that affect asteroids' orbital paths and their potential for impacting Earth, and the origins of life in the solar system. In addition, OSIRIS-REx will collect a sample from the surface of the asteroid and return it to Earth for generations of scientists to study and analyze, making this the first American asteroid sample return mission and the largest sample returned from an extraterrestrial body since Apollo.

OSIRIS-REx's was launched on September 8, 2016.

Living Among Giants: Exploring and Settling the Outer Solar System by Michael Carroll

Michael Carroll’s „Living Among Giants“  Explorer the other solar system from the perspective of it being a potential destination for manned missions, colonization and as a vacation destination in the future.

The book is divided into three parts, all of which are excellently illustrated.

The first part of the book looks at the solar system in general, how the planets formed, and the space missions that have sent us back data about the other solar system from the Pioneer spacecrafts to Cassini and a few possible missions that are still in the future.

In the second part of the book we have a much closer look at the giant planets, what distinguishes them from one another and about the discovery of their moons and different aspects of them. Naturally more attention is on the larger moons, such as the four Galilean moons, the fascinating Titan and Triton. The overview gives the moons more of a character so you can see that they’ve all got something interesting an special about them.

The final part of the book looks at how we might get there – what kind of technology is necessary, and what kind of options do we already have for sending spacecrafts there – so you can get a quick overview of different propulsion systems that might for example eventually take the first manned mission to Titan.

Living Among Giants is a fascinating book with excellent detours into what some planetary scientists would like to visit on different moons – what views would be the coolest? What sort of cruise to take to have the best views of Saturn’s rings, or what kind of crater, chasm, cryovolcano or any other feature would be interesting to explore.
