Falcon 9 first stage returns to port, with a noticable list
The competition heats up: The first stage from SpaceX’s most recent Falcon 9 launch returned to port today, showing a visible lean.
Musk said that the stage was probably OK, but there was some risk of tipping. This was due to the fact that the contingency “crush core” was used up. He described on Twitter that the crush core was an aluminum honeycomb for energy absorption in the telescoping actuator. Once the stage was within sight of land, it became clear that the booster had a noticeable lean to it, due to the aforementioned contingency crush core being used up. The ramifications of this are still unclear, but Musk’s tweet implied that the crush core is easily replaceable.
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

From the article: “Rocket landing speed was close to design max,”
I hope that the high speed landing was due to a planned test of the rocket’s abilities rather than an accident.
