More details from Loren Grush.
As I write in my project: “There was an old saying on the American frontier about the Mississippi River: ‘It’s too thick to drink, but too thickn to plow.’ Similarly, the Martian atmosphere has been tantalizing aerodynamicists for decades.” They really need to stop trying to use the Martian atmosphere if they want to drop serious payload.

The Obama Economy
He’ll be the first president ever to never see a year of 3% growth.
Despite all the Democrat hype about “X months of job creation,” the jobs don’t pay that well, and there haven’t been enough of them to keep up with population growth. This nonsense about “saving the world from a depression” is just that — no one knows what would have happened without the Democrats bailing out the public-employee and auto unions. It’s a counterfactual. But one can trace the nation’s economic problems to 2006, when the party that hates economic growth took over Congress.
