A history, over at Ars Technica. In addition to the balloon tanks, there were concerns with the common bulkhead between the LOX and LH2 tanks (though AFAIK this has never caused a Centaur failure).
As I’ve written before, there was an alternative approach, that NASA never considered.
Tom Vilsack: “I wish there were scientific facts.”
Pro tip to Vilsack. An “informed opinion” not based on scientific facts is an uninformed opinion.
And here’s a nice bit of illogic:
Lawmakers also noted that federal nutrition guidelines could be considered a failure because of the country’s high obesity rates. But Burwell fought back, arguing that obesity would be much worse had the guidelines not been in place.
“We are on the wrong trajectory, but would the trajectory have been worse?” Burwell said, acknowledging there was an obesity problem.
Since it was the original crap low-fat guidelines from the government that caused the problem, no, there’s no reason to consider them a success, or to not end the insanity.
I didn’t live tweet it, but here are some tweets from Jeff Foust on Gibson’s #ISPCS comments yesterday:
Can it be justified in a time of crisis? An hilarious SSRN abstract.

Sorry, missing link has been added.
This looks like an interesting event tomorrow.
I got up early this morning, flew to El Paso, and then drove up to Alamagordo to the space history museum. In Las Cruces now. I’ll check in from the event tomorrow.
An interesting history.
Even the film-makers had doubts:
“If you had told me two years ago when we were walking into Fox to pitch the approach and what this movie would be, if you told me I’d be on the phone talking about how this is a big spectacle movie, I would have been delighted,” he tells Esquire. “At the time, we knew it was going to be expensive, but we thought it would be more niche than Ridley made it.” Nope.
What made The Martian unique also made it a difficult sell. It was not an action movie. The film’s star would spend his time farming potatoes harvested from his co-astronaut’s feces. The Rock would not show up to blow away aliens halfway through the second act. Mind would prevail over muscle. And that’s not easy to write for the masses.
I hope it will break some of the stereotypes, and make it easier to make these kinds of films.
