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
This was the first time ever that a commercial robotic satellite docked with a second commercial satellite for such a purpose. It was also the first time such a docking has been done using no government funds.

MEV-1 will stay docked to this satellite for about five years, providing it attitude control and guidance. The robot will then move the satellite into a safe graveyard orbit, detach, and be then capable of docking with a second satellite to extend its life as well. Moreover, Northrop Grumman is building a second MEV, with the hope it will be hired to save other satellites.
This achievement lays the foundation for a new stage in commercial space. It proves that unmanned robots can dock with objects in space, both to repair them and extend their life, but also to remove them from orbit and thus reduce the quantity of space junk.
