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 today issued an explanation for why it had not responded when ESA officials had asked them to change the orbit of one of its Starlink smallsats to protect against a possible collision with ESA’s Aeolus spacecraft.
SpaceX, in a statement Sept. 3, said it was aware of a potential conjunction Aug. 28 and communicated with ESA. At that time, though, the threat of a potential collision was only about 1 in 50,000, below the threshold where a maneuver was warranted. When refined data from the U.S. Air Force increased the probability to within 1 in 1,000, “a bug in our on-call paging system prevented the Starlink operator from seeing the follow on correspondence on this probability increase,” a company spokesperson told SpaceNews.
“SpaceX is still investigating the issue and will implement corrective actions,” the spokesperson said of the glitch. “However, had the Starlink operator seen the correspondence, we would have coordinated with ESA to determine best approach with their continuing with their maneuver or our performing a maneuver.”
This incident increasingly strikes me as a tempest in a teapot created by ESA for any number of reasons, including their overall dislike of SpaceX (for generally making all government-run space programs look foolish). There is also this quote from an ESA official in the article above:
“The case just showed that, in the absence of traffic rules and communication protocols, collision avoidance has to rely on the pragmatism of the involved operators,” Krag said. “This is done today by exchange of emails. Such a process is not viable any longer with the increase of space traffic.” He said that, if the Space Safety initiative is funded, ESA would like to demonstrate automated maneuver coordination by 2023. [emphasis mine]
I can just see ESA officials drooling with eager anticipation the coming of more “traffic rules and communication protocols,” partly inspired by this fake crisis they just created. Imposing more rules and getting increased funding is what they do best, since it certainly isn’t exploring space with creative and efficient innovation.
