Russia returns Soyuz rocket to flight
As expected, Russia returned the Soyuz launch vehicle to flight in a
startlingly short amount of time. Russia returns Soyuz rocket to flight with Lotos-S1 mission written by William Graham October 24, 2018 https://www.nasaspaceflight.com/2018...ight-lotos-s1- mission/ From above: Thursday's launch had originally been scheduled to take place last week but slipped a few days in the immediate aftermath of the MS-10 launch. Naturally, this schedule slip of just a few days indicates how thoroughly Russia investigated the failed crewed launch of Soyuz and how diligently they inspected this Soyuz launch vehicle for any other quality control problems. /s Of course, NASA Spaceflight rarely paints less than a perfectly rosy picture of anything that NASA does, so I didn't expect them to be openly critical of Russia's launch operations. After all, NASA keeps telling us that everything is fine and that we'll continue to fly NASA astronauts on Soyuz. Nothing to see here, just move along.

Russia returns Soyuz rocket to flight
They're taking a calculated risk. On one hand, Soyuz has flown for half a
century with only a few mishaps. On the other hand, not flying means risking the $100 ISS in case something goes wrong and there's no crew on board to fix it. So I believe the risk taking is justifiable. "Jeff Findley" wrote in message ... As expected, Russia returned the Soyuz launch vehicle to flight in a startlingly short amount of time.

Note that this is not a manned launch, so it's a different model of Soyuz (but has the classic R-7 Stage 1 and Stage 2 configuration). This launch (and two others) are part of their mitigation strategy. They want three successful launches before a return to manned service. Naturally, this schedule slip of just a few days indicates how thoroughly Russia investigated the failed crewed launch of Soyuz and how diligently they inspected this Soyuz launch vehicle for any other quality control problems. /s Not a crewed launch. The next two won't be, either. Note that SpaceX only did a four month pause to investigate a much more serious issue that was, at least initially, much less understood. Of course, NASA Spaceflight rarely paints less than a perfectly rosy picture of anything that NASA does, so I didn't expect them to be openly critical of Russia's launch operations. After all, NASA keeps telling us that everything is fine and that we'll continue to fly NASA astronauts on Soyuz. Nothing to see here, just move along. They seem to have a pretty good handle on what happened and why and it sounds like a 'one off' issue. -- "Insisting on perfect safety is for people who don't have the balls to live in the real world." -- Mary Shafer, NASA Dryden |

After all, NASA keeps telling us that everything is fine and that we'll continue to fly NASA astronauts on Soyuz. Nothing to see here, just move along. They seem to have a pretty good handle on what happened and why and it sounds like a 'one off' issue. Look at the totality of the "one off" issues they've had in their launch vehicles over the last 20 years. That looks a lot like a systemic quality control problem to me. One of the reported causes of this failure was that the crane crew installing the failed booster bent a connecting pin on the top connection point. Instead of fixing the issue, they used lubricant on it and forced the booster onto the launch vehicle. If this proves to be the cause, it's looking like the Russian "safety culture" is horribly flawed. Yeah, but we kind of know that and don't have a lot of choice but to live with it. Should I point out to Mayfly that this lines up exactly with my 'guess' that he was trying to excoriate me for? R-7 and Proton type vehicles have been flying since before I was born. We really should not be seeing so many "one off" failures in such mature designs. As much as I despise ULA for not innovating, their success rate has been absolutely stellar over the very same time period. Yeah, but then you wind up with silliness like the year slide in the Vulcan schedule out to April of 2021. I knew they wouldn't be able to meet their original schedule when it took them so long to select an engine. I'll just note that on this year's launches there has been one R-7 failure and one Ariane 5 failure. It looks like they've been running one R-7 failure a year for the last several years. -- "Insisting on perfect safety is for people who don't have the balls to live in the real world." -- Mary Shafer, NASA Dryden |
