Cause of Progress failure unlikely to be found
Not good: Sources in the Russian press say that it will likely be impossible to pinpoint precisely the cause of the Progress failure this week because of a lack of telemetry or data.
The causes of Thursday’s loss of the Progress cargo spacecraft are unlikely to be established, because neither telemetry data nor debris of the Soyuz-U rocket that was taking the cargo vehicle in orbit are available. “Telemetry transmission from the rocket was disrupted instantly, so it is practically impossible to establish the sequence of events to identify the causes of the emergency. As for material evidence, such as debris of the rocket’s third stage that might provide some clues, it is not available, either,” the source said.
They are still searching for debris but have so far come up empty.
Lacking data, they are now beginning to use computer modeling to try to figure out what happened. The prime suspect is the third stage engine.
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

As I understand it, this is the same launch vehicle as used for manned Soyuz launches. This is not very good situation to be in for manned access to the ISS. Maybe NASA ought to be looking at ways of speeding up, if possible, development of Boeing and Spacex capsules. With what appear to be quality control issues with Russian launchers can we trust their reliability for manned launches? If they can’t explain with some certainty what happened with the third stage can we trust putting our astronauts on it?
Hindsight is 20-20 but wonder why more importance wasn’t given to having two manned launch alternatives before retiring the space shuttle. It only seems prudent to have a backup in case the something goes wrong with Soyuz. Maybe the high reliability of Soyuz reduced apparent need for a backup. Most arguments for alternatives center around having Americans riding an American rocket and eliminating the gouging fees the Russians are charging for a ride.
I’m thinking that we ought to get Spacex and Boeing delivery speeded up as much as practical.
