- Amazon confirms the 24 satellites launched yesterday by SpaceX are all functioning as planned
It also says they were deployed every 20 seconds over 8 minutes.
- Boeing touts its progress in building SLS’s more powerful upper stage, intended to increase SLS’s power to approximately match the Saturn-5
As Jay notes, “This is kind of painful to watch and read.”
- On July 16, 1969 Apollo 11 was launched
The tweet is by Buzz Aldrin, still going strong.
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. from any other book seller, or direct from my ebook publisher, ebookit.
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

“100 Ton Test” (May 7, 1945)

“To help in preparing the instrumentation for the Trinity shot, 108 tons of TNT/RDX high explosive was stacked on a wooden platform 800 yards from Trinity ground zero and detonated. The pile of high explosive was threaded with tubes containing 1000 curies of reactor fission products. The test allowed the calibration of instruments to measure the blast wave and gave some indication of how fission products might be distributed by a nuclear explosion.”
I am looking forward to the EUS, a second stage that won’t cartwheel. Pyrios needs Buffet to invest in it.
