‘NASA is wrestling with a potentially dangerous problem in a spacecraft, this time in a moon rocket that hasn’t even been built yet.
Engineers are concerned that the new rocket meant to replace the space shuttle and send astronauts on their way to the moon could shake violently during the first few minutes of flight, possibly destroying the entire vehicle.
“They know it’s a real problem,” said Carnegie Mellon University engineering professor Paul Fischbeck, who has consulted on risk issues with NASA in the past. “This thing is going to shake apart the whole structure, and they’ve got to solve it.” [..]
Professor Jorge Arenas of the Institute of Acoustics in Valdivia, Chile, acknowledged that the problem was serious but said: “NASA has developed one of the safest and risk-controlled space programs in engineering history.”‘
.. that last comment means almost nothing when engineering history has so few space programs in it. 🙂
