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
The reason I am qualifying the success of the launch at this moment is that, because of the national security nature of the payload, they will only release details about the success of the final orbital maneuvers long after they have been completed. Right now these details are blacked out. Update: the launch was successful.
ULA has another launch of an NRO satellite scheduled for October, a date not yet determined. Right now, the U.S. has had 20 launches in 2017, far more than any other nation, with SpaceX’s 13 launches comprising the bulk.
