I join this recommendation; these are almost a sourcebook for Fusion Age interplanetary play, planetary colonization, terraformation and more-or-less feasible technological development. These books are also an excellent read.It just occurred to me last night: the Space Elevator attack may not have been in Bova's series. There is another very good Fusion Age series of books written by Kim Stanley Robinson: Red Mars, Green Mars, Blue Mars and a short story collection called The Martians.
The books cover about 200 or so years of exploration and terraforming of Mars.
