After being in print for twenty years, the Chronological Encyclopedia of Discoveries in Space, covering everything that was learned on every single space mission in the 20th century, has finally gone out of print.

"Useful to space buffs and generalists, comprehensive but readable, Bob Zimmerman's Encyclopedia belongs front and center on everyone's bookshelf." -- Mike Collins, Apollo 11 astronaut
"The Chronological Encylopedia of Discoveries in Space is no passionless compendium of information. Robert Zimmerman's fact-filled reports, which cover virtually every spacecraft or probe to have ventured into the heavens, relate the scientific and technical adventure of space exploration enthusiastically and with authority." -- American Scientist
At the moment, Lockheed does not have a competitive rocket. Moreover, its only big space project is Orion, which might never fly more than twice, if that. Thus, this shift to satellites makes some sense, as it will be difficult now for the company to gain market share in the launch and manned spacecraft markets. It is too far behind. However, there is a new industry developing in smallsats, and Lockheed is well positioned to get in at the start.
Update: I do this all the time, but I made a mistake here and assigned the Delta family of rockets to Lockheed Martin. For some reason I make this mistake often, switching Atlas 5 and Delta and Lockheed Martin and Boeing. I apologize for the error.
