First commercial crew flights still set for 2018 with chance of delayNASA’s manager of the commercial crew program provided an update to the agency’s advisory board on Monday, noting that both SpaceX and Boeing are making good progress to their scheduled first flights late this year.
The bottom line however is that there is a good chance the flights will slip into 2019, though based on the update it appears to me that the flights will not slip that much beyond that.
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 print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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

Remind me again how long it took from GO! to landing on the Moon and returning safely to Earth, starting from a knowledge base much smaller than what we have now.
Mike Borgelt: Well, Kennedy’s speech committing us to go to the Moon took place in May 1961. We landed on the Moon in 1969, just over eight years later.
A better measure would be to use the launch of Sputnik in 1957 as the GO! point. With that measure, it took 12 years to get to the Moon.
Either way, SLS/Orion is an embarrassment in comparison, especially since it is using engines that already exist and concepts already proven.
