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.
"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
Capitalism in space: SpaceX today successfully completed a 150-meter high hop of its sixth Starship prototype, the second such hop but the first for this prototype. They have now flown two different prototypes, plus Starhopper, all successfully. No flight failures, so far.
Next they will be doing a pressure tank test, to failure, of the seventh prototype. That prototype is using what they think will be a better steel alloy, and they want to find out its limits. I have also heard that they will either fly this prototype again or fly the fifth again, sometime in the next two weeks.
I have embedded a few more images below the fold.
To the right a close-up, shortly after take-off. The single Raptor engine at the base is tilted slightly to compensate for the vehicle’s overall tilt as it slides leftward to its landing site. Note the stubby legs at the base.
The first image below is a long shot showing the prototype shortly after the smoke cleared, sitting safely on the ground. Like the fifth prototype, the sixth is also leaning slightly, though as much.
The last picture is a close-up shortly after landing. You can see a fire at the prototype’s base. Fire suppression equipment quickly put this out.
