Expedition Mars

"In this book, Martin Turner shows how modern technologies not only make such a journey possible, but that advances in those technologies will make it more probable, and that the first human mission to Mars will happen within our lifetime." "The latest rocket propulsion, spacecraft technology and planned developments in nuclear and electric propulsion technologies are the key factors which will enable this journey to take place. Of particular importance is the necessity to transport cargo to Mars, and to provide essential life support for the crew - food, water, air and fuel - to enable the return journey." "Expedition Mars challenges us to face the fact that, sooner or later, humans will have to make a choice: stay here on Earth or explore the Solar System beyond."--Jacket.
