Russians trace Soyuz rocket failure to a bent sensor; next crew to launch Dec. 3

Russian investigators say final month’s launch of a Soyuz rocket carrying two spacefliers to the Worldwide House Station went awry as a result of (*3*).

When the broken sensor malfunctioned, the booster didn’t separate cleanly from the Soyuz’s core, throwing the rocket off track and forcing an abort sequence simply minutes into the Oct. 11 ascent. The Soyuz crew capsule was thrown away from the rocket and made a parachute-aided descent. Thanks to the escape system, NASA’s Nick Hague and Russia’s Alexey Ovchinin made a safe landing in Kazakhstan.

House station managers frightened that the failure would possibly pressure an prolonged suspension of Soyuz flights. However Russia’s Roscosmos house company mentioned three different spacefliers — NASA’s Anne McClain, Canada’s David Saint-Jacques and Russia’s Oleg Kononenko — can be launched to the station on Dec. 3.

That’s assuming that three uncrewed Soyuz rocket launches scheduled between at times go off with out a hitch. These missions embody two satellite tv for pc launches, on Nov. 3 and Nov. 6, and a robotic Progress cargo resupply mission on Nov. 16.

FATAL IMPACT: Right here is the second when a strap-on booster delivered a deadly blow to the core stage.

AND HERE IS THE CULPRIT: This little sensor by accident bended by round six levels throughout the meeting of the launch car is now blamed for the #SoyuzMS10 accident. DETAILS:

In a mission update posted today, NASA mentioned it was “working carefully” with Roscosmos on future crew launch plans. These plans presumably embody rescheduling a flight for Hague and Ovchinin.

The next few weeks will likely be marked by a variety of comings and goings on the station. As well as to the Progress cargo cargo, Japan’s robotic HTV-7 resupply ship is due to be set loose for disposal on Nov. 7, and Northrop Grumman is scheduled to launch a Cygnus cargo provider on Nov. 15.

Immediately’s findings concerning the sensor harm may add to high quality issues about Russian house {hardware}. In August, the house station crew had to deal with a worrisome air leak in a Soyuz capsule that was docked to the station. The leak was traced to a hole apparently drilled in the Soyuz’s hull.

Kononenko and one of many station’s three present crew members, Russian cosmonaut Sergey Prokopyev, are due to examine the leak from the surface throughout a Dec. 11 spacewalk.

Assuming every thing goes easily, Prokopyev and two different spacefliers, NASA’s Serena Auñón-Chancellor and Germany’s Alexander Gerst, would trip the patched-up Soyuz again down to Earth on Dec. 20, leaving the three freshly arrived crew members on the station.
