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 nine finalists in the Mars 2020 rover naming contest have been chosen, out of 28,000 entries from schools across the United States.
The nine candidate names were made possible by the “Name the Rover” essay contest, which invited students in kindergarten through 12th grade from across the United States to come up with a fitting name for NASA’s Mars 2020 rover and write a short essay about it.
More than 28,000 essays were submitted after the contest began on Aug. 28 last year. A diverse panel of nearly 4,700 judge volunteers, composed of educators, professionals and space enthusiasts from all around the country, narrowed the pool down to 155 deserving semifinalists from every state and territory in the country.
The public now gets to vote for their favorite, the choices of which are: Endurance, Tenacity, Promise, Perseverance, Vision, Clarity, Ingenuity, Fortitude, Courage. For the next week you can vote here. NASA will then take the poll results into consideration before making its final choice.
My personal favorite is Endurance. Vote for your own.
