The Latest Progress Failure

The report has been released:

Members of the commission established that the most probable cause of the accident had been the disintegration of the oxidizer tank of the third stage as a result of the failure of the 11D55 engine, following the fire and disintegration of its oxidizer pump, Roskosmos said. The fire in the pump and its disintegration could be triggered by a possible injection of the foreign particles into the pump’s cavity or by violations during the assembly of the 11D55 engine, such as a wrong clearance between the pump’s shaft and its attachment sleeve, floating rings and impellers, leading to a possible loss of balance and vibration of the rotor.

Sounds like they still have serious QA issues, either in manufacture or processing. And it’s the same third stage that crew uses.

Geoengineering, Space Tech, And Societal Risk

Some interesting thoughts from Oliver Morton (who I unfortunately missed having lunch with in London last week, maybe next time):

AI worries people more, but geoengineering seems pretty well placed in second place. (Incidentally, what’s up with space as the top societal risk enhancer? If AI takes the laurels in terms of economy, geopolitics and tech, how come space outdoes it in the exacerbation of societal risks? A mystery for another time…)

Indeed. I have some ideas, and that some it arises from ignorance and too much bad SF in television and movies, but I’ll let the commenters have at it.

Moon Or Mars?

The latest on the issue.

It’s a pointless discussion, because it presumes it’s going to be a government program: Apollo back tot the moon again, or Apollo to Mars. We need to be developing capabilities to go wherever we want, affordably. Then let the people paying for it decide.
