Rocket Investigation Complete; Russia, Japan Announce Mission Updates

The Soyuz MS-10 spacecraft launched Oct. 11, 2018
The Soyuz MS-10 spacecraft launched Oct. 11, 2018, with Expedition 57 crew members Nick Hague of NASA and Alexey Ovchinin of Roscosmos. During the Soyuz spacecraft’s climb to orbit, an anomaly occurred, resulting in an abort downrange. The crew was quickly recovered in good condition.

NASA is working closely with its International Space Station partner Roscosmos to move forward on crew launch plans. Roscosmos plans to launch the Progress 71 resupply mission on Nov. 16, and is targeting the launch of the Expedition 58 crew including NASA astronaut Anne McClain for Dec. 3, pending the outcome of the flight readiness review.

Roscosmos completed an investigation into the loss of a Soyuz rocket last month that led to a suspension of Russian rocket launches to the station. One of four first stage rocket engines abnormally separated and hit the second stage rocket that led to the loss of stabilization of the Soyuz on Oct. 11. A statement from Roscosmos describes the cause…

“The reason for the abnormal separation is the non-opening of the nozzle cap of the “D” block oxidizer tank because of the deformation of the stem of the separation contact sensor (bending on 6 ˚ 45 ‘), which was admitted when assembling the “package” at the Baikonur Cosmodrome. The cause of the LV accident is of operational nature and extends to the backlog of the “Soyuz” type LV “package”.”

Japan also announced today the release of its H-II Transfer Vehicle-7 (HTV-7) resupply ship, also called the Kounotori, from the station’s Harmony module. Commander Alexander Gerst will command the Canadarm2 robotic arm to release Kounotori Nov. 7 at 10:50 a.m. EDT as Flight Engineer Serena Auñón-Chancellor supports him.

  1. the next question in each type of spacecraft manufactured with quality controls.. do we have a similar percentage or length volume deformation which under severe thermal and mechanical stresses for say one in x times manufactured…. which would have a form deficiency for the pattern available in atmospheric conditions which are apparently more severe in turbulence and global area meteorological scales although not locally in the vicinity to the craft, so it would seem, but certain aerosols now later acknowledged as available in solution of the global atmosphere even where the spacecraft launched… then could possibly contribute to the disassembly of the portions of the craft in that particular instance… from limitations with the deformity in harsh conditions to the craft undetected in the initial probe… So tolerances of parts perhaps a decrease in at least some of the dimensions of the spacecraft manufacturing
