The European Space Agengy (ESA) has now completed its full investigation of a Vega rocket launch failure in November, and confirmed that the initially announced cause of “human error” was correct.
Engineers had installed cables backwards causing the nozzle in the upper stage to go one way when it should have gone the other.
The press release at the link is a wonder of bureaucratic cover-your-behind gobbly-gook, saying much without providing any concrete information about the corrections imposed. For example, the upper stage structure is built by one company, Airbus, the engine is built by two Russian companies, Yuzhnoye and Yuzhmash, while a fourth company, Avio, supervises the stage’s assembly. The press release makes it a point to not tell us where the error was made by which company, though by vague implication it suggests the error occurred during final assembly by Avio.
If I was a satellite company thinking of buying a Vega launch I would demand a much more straight-forward explanation. Otherwise I’d go elsewhere.

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space
, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.
