June 16, 2017 Zimmerman/Batchelor podcast
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Did the last flight of the Dragon spacecraft (CRS-11) to the ISS have in flight abort capabilities?
Danny,
No. The Dragon 1 does not have in-flight abort capability and cannot be retrofitted to do so. The Dragon 2 will have in-flight abort capability. That will apply whether it is carrying crew or doing an all-freight run by the way.
The Dragon 1’s software, however, was modified after the CRS-7 accident to deploy chutes if it finds itself intact and falling before getting to orbit. The CRS-7 Dragon survived the in-flight breakup of the booster’s 2nd stage and could have survived if it had deployed its chutes. But that particular scenario had not been allowed for in its control software. Now it is.
I believe SpaceX intends to reuse its existing stock of flight-proven Dragon 1’s by refurbishing them, as needed, until Dragon 2 enters service – initially for crew transfer and, at some point soon thereafter, in an all-freight version. The refurbed Dragon 1’s may continue in service beyond Dragon 2’s entry into service also if NASA or some other customer needs their abilities. But no more Dragon 1’s will be built after SpaceX converts the production line over to exclusively Dragon 2 output. Retired Dragon 1’s will probably all wind up in museums eventually.
