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
Two experiments will be flown on both landers. The Astrobotic lander gets an additional nine instruments, while Intuitive Machines gets three.
The most interesting tidbit from the press release is that NASA hopes to make “about two deliveries of scientific and research payloads to the Moon per year starting in 2021.” Seems overly optimistic to me, though in the long run the approach makes sense for NASA. These landers are relatively small and cheap, so the cost to fly a lot of them is not exorbitant. Under this arrangement, if one fails you simply figure out why and quickly fly another.
For this new American industry the approach also works. The companies will own the designs, so soon they will be able to market this technology to other customers, at what is historically record low prices for such a mission. The result is likely going to be the arrival of a swarm of new customers.
