Somehow, Someday: Prospects for Spacefaring

If you were asked whether humans will have colonized space by the year 2500, chances are you'd say yes. But in light of current realities, political and otherwise, how might that goal be achieved? In this wide-ranging essay, Neil deGrasse Tyson's longtime editor investigates the present state and long-term possibilities of spacefaring -- encouragements versus impediments, competition versus cooperation -- with reference not only to the United States but to humanity as a whole. SOMEHOW, SOMEDAY is an inviting, provocative read, both for nonscientists who would like to get a quick but substantive overview of space issues and for scientists interested in policy and public awareness.
