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
A proposed House bill would forbid use of Russian rocket engines in launching any American military payloads.
This bill is being put forth partly because of the Ukrainian situation and partly to support SpaceX’s effort to break the ULA Atlas/Delta monopoly on military launches. Whether it makes any sense or not is of course beside the point.
Meanwhile, the State Department has expanded the sanctions on satellite exports to Russia, which might threaten some future commercial Proton launches.
Both actions suggest that Elon Musk’s political clout is growing. Obviously his company’s concerns are not the prime motivation behind these decisions, but we should note that both actions hurt his direct competitors, while doing little harm to SpaceX.
