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 European Space Agency (ESA) has asked for help from NASA in trying to figure out the cause of the failures during testing of the parachutes they want to use to safely land their ExoMars 2020 rover, Rosalind Franklin.
So far the parachutes have been damaged on all previous tests. They plan two more tests in December and February.
Both tests, to be held at high altitude to simulate the Martian atmosphere, need to succeed in order for the parachutes to pass qualification. TheExoMars mission faces a final review scheduled April 2020, Francois Spoto, ExoMars program manager, told SpaceNews. “Now the situation is critical, of course, because we have limited time and no margin,” Spoto says.
If one of the tests fails, the ExoMars mission will miss the narrow July 25 to Aug. 13 launch window next year and slip to the next window, in late 2022. The lander and rover segments are meanwhile progressing well and ready for environmental testing.
They held a workshop on the previous failures, and obtained new analysis of the causes from JPL engineers.
