A fascinating selection of "Analog" magazine's finest articles by leading researchers and science writers. Contains an astonishing range of new proposals for space travel and colonization including plans for the exploration of Mars, ideas for interstellar travel at the speed of light and the process of terraforming other planets to accommodate human life. Describes the latest in space exploration research and development by the world's foremost astronautic engineers.
A lot of excellent material and a handful of not-so-hot selections. This anthology of articles, mostly by scientists and engineers many of whom also write science fiction, examines multiple possibilities in terms of both technologies and destinations.

Other authors look at economic and social concerns, so it's a balanced overview, addressing possibilities throughout the solar system, in interstellar space, and ultimately around other stars. Makes me wish I was my grandson's age with at least a plausible possibility of seeing some of the places discussed.
