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 test flight will also carry four commercial nanosats.
Both Planet and Spire — two companies that operate small satellites in orbit — will have payloads on the Electron’s second test flight, dubbed “Still Testing.” The rocket will carry two of Planet’s Dove satellites, designed to image Earth, as well as two of Spire’s Lemur-2 satellites that track weather and ship traffic.
The company also states that if this second flight is successful, they might forego a third test flight and move directly to commercial operations.
