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
SpaceX has decided to withdraw its protest against NASA’s decision to choose ULA as the launch vehicle for its Lucy asteroid mission.
The company did not provide any reason for the withdrawal. I suspect Musk decided that it was doing SpaceX harm both publicly and privately. Publicly it threatened the launch date of Lucy, which might cause a significant and fatal delay to the mission. That did not make SpaceX look good to the general public.
Privately, I suspect that the protest was hurting SpaceX with NASA officials. They almost certainly did not say so directly, but I am certain they were able to make this clear in any number of ways. This, combined with the agency’s new willingness to consider commercial rockets, like the Falcon Heavy, for its lunar plans, probably convinced SpaceX that it was doing itself more harm than good with the protest.
