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
A good translation of this week’s press release from the investigation into the April 28 Progress failure indicates that the failure occurred because of an abnormal separation of the freighter from the upper stage.
After reviewing all the materials, members of the State Commission came to a preliminary conclusion that a version of the abnormal separation had been objectively confirmed, which includes two subsequent events related to the depressurization (disintegration after the cutoff of the third-stage engine) first of the oxidizer tank and then of the fuel tank, Roskosmos said.
In other words, the separation was so abnormal it put both the freighter and the upper stages in the wrong orbits, with the Progress tumbling and damaged, and with the upper stage almost immediately disintegrating.
They are now studying the data to try to figure out what caused the bad separation so they can inspect other Soyuz upper stages for the same problem and fix them before launch.
