Russian Soyuz rocket launches military satellite
Only two weeks since a Soyuz rocket failure during a manned launch the Russians have resumed Soyuz launches with the lift-off today of a military reconnaissance satellite from their Plesetsk spaceport.
The article provides this extra piece of information about the failure two weeks ago:
While investigations into the failure have not yet concluded, initial reports have suggested that one of the four boosters that comprise the first stage of Soyuz failed to separate cleanly. This is believed to have made contact with the second stage, puncturing one of its propellant tanks and throwing the rocket out of control.
This resulted in thrust termination – the rocket’s engines being shut down as a safety measure – and triggered the spacecraft’s automated abort mechanism.
No root cause has been announced. However, speculation initially pointed at a failure of a valve to open that would have vented residual oxidizer from the booster, pushing it away from the vehicle.
Later reports have suggested that the booster was installed incorrectly when the rocket was assembled – having been forced into a mounting lug that was bent out of shape in the process. A similar anomaly reportedly occurred during an unmanned launch in March 1986. The Russian State Commission into the MS-10 failure is expected to deliver its report at the end of the month. [emphasis mine]
The launch does bode well for resuming manned launches in December, as originally planned. That it is possible that this problem has occurred previously and has reoccurred is not good. One would have thought they would have instituted engineering design changes to prevent a repeat.
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. from any other book seller, or direct from my ebook publisher, ebookit.
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
