SpaceShipTwo’s engine did not cause failure
The investigation into the failure of SpaceShipTwo last week during a powered flight test has determined that the accident was not caused by the spaceship’s engine and that the spaceship’s feathering system for return to Earth began deploying early during powered flight.
The ship’s fuel tanks and its engine were recovered intact, indicating there was no explosion. “They showed no signs of burn-through, no signs of being breached,” Christopher Hart, acting chairman of the National Transportation and Safety Board, told reporters at the Mojave Air and Space Port in Mojave, Calif
Instead, data and video relayed from the ship show its hallmark safety feature — a foldable tail section designed for easy re-entry into the atmosphere from space — was deployed early.
More here. Deployment required two commands, activation and then deployment. Data shows that the co-pilot Michael Alsbury activated the system slightly early. The second command, however, was not given, but the feathering system began to deploy nonetheless, during powered flight when the ship was accelerating upward. That is when the ship broke up.
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
