Dispute in Russia over Progress failure investigation
The Russian mission control has publicly disavowed a report that cited mission control as saying that the failure of the Soyuz/Progress launch last week was due to the premature shutdown of the Soyuz rocket’s third stage.
First the source:
A source in the space and rocket industry told TASS that the emergency shutdown of the engines occurred after 382 seconds and at the same time the spacecraft’s separation occurred. After that, the flight control system started operating in automatic flight mode and began deploying antennas and solar batteries. However, the spacecraft failed to reach orbit and started falling and ended up being destroyed in the atmosphere.
Next the disavowal:
”Any version which are now being voiced by the media have nothing to do with reality, including the incorrect cyclogram data. The results of the commission’s work will be announced no earlier than December 20,” a spokesperson told RIA Novosti.
I must admit that the source’s suggested cause for the failure, that the rocket engine shut prematurely and the spacecraft then simply separated and began its deployment before it had reached orbital velocity and thus fell back to Earth, sounds good at first glance. However, this explanation does not explain why all communications with the spacecraft suddenly ceased.
Either way, it does appear that there is an effort within Roscosmos to spin the events in the press, prior to the completion of the investigation. This in itself is not a good sign, as it suggests that there are people there who are trying to cover their asses rather than honestly trying to find out the cause of the failure.
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

Mr. Zimmerman: Please correct “escape velocity ” in “orbital velocity”. Thank you.
Alex: Done. Thanks.
