In the coming years, we will make decisions regarding our human spaceflight program that will lead to one of two familiar futures: the open universe of "Star Trek, "where we allow ourselves the opportunity to spread our wings and attempt to flourish as an interplanetary species--or the closed, dystopian, and ultimately self-destructive world of "Soylent Green." If we ever hope to live in the future that is the former scenario, our first stepping stone must be a manned mission to Mars. In this four-part e-special, Dr. Robert Zubrin details the challenges of a manned Earth-to-Mars mission. Challenges which, according to Zubrin, we are technologically more prepared to overcome than the obstacles of the missions to the moon of the sixties and seventies. Dr. Zubrin's relatively simple plan, called Mars Direct, could feasibly have humans on the surface of Mars within a decade. Zubrin also discusses the current predicament of NASA, the promise of privatized space flight from companies like SpaceX, and the larger implication behind the absolute necessity to open the final frontier to humanity--the human race's future as a species that takes the necessary baby steps away from the cradle that is planet Earth or, ultimately, perishes here.

    As huge as the Pantheon of Rome and as heavy as the Statue of Liberty, this magnificent instrument is so precisely built that its seventeen-foot mirror was hand-polished to a tolerance of 2/1,000,000 of an inch. The telescope's construction drove some to the brink of madness, made others fearful that mortals might glimpse heaven, and transfixed an entire nation. Ronald Florence weaves into his account of the creation of "the perfect machine" a stirring chronicle of the birth of Big Science and a poignant rendering of an America mired in the depression yet reaching for the stars.

He also looks at how we might strive to overcome the limitations of the physical universe and win the deepest future. Stephen Baxter has brought his trademark narrative flair and imaginative brilliance to the latest ideas in physics and cosmology and produced a breathtaking guide to our possible futures.
