Houston, We Have A Market

Greg Autry writes about the success of COTS:

When it comes to the International Space Station resupply business, these firms are competing with governmental operations from Russia and Japan. Congressional defenders of the old-school government-operated space service are curiously disdainful of American entrepreneurship and eagerly point out how these foreign solutions can fill our needs while we compel NASA to build a Space Shuttle replacement. What these critics miss, however, is that every dollar going to one of our domestic firms stays in the U.S., creates serious jobs, and makes the most of America’s entrepreneurial advantages. Funding this investment in America’s future follows in the steps of successful Federal investment in jumpstarting industries that have included the transcontinental railroad, the Internet, and GPS. Such visionary investments have produced big economic returns that increased government revenues for decades.

They don’t care. It’s all about the pork.

The SpaceX Press Conference

Elon is saying that the mission was completely successful, but they lost the first stage. First relight to gentle the entry was successful, but the second one to come into the ocean resulted in an exceedance of attitude control authority for roll. Centrifuged propellant shut down engine prematurely. But they’re getting all the pieces, so they’ll be able to figure out how to fix for next time.

First and second stage engines performed better than predicted. Pad also worked well.

Second stage shut down prematurely, but didn’t affect mission, apparently. They know why and will fix for next flight. Next two flights won’t attempt first-stage recovery, in order to maximize payload for customers. [All via @Jeff_Foust]

Next recovery attempt will be on CRS-3. Vehicle may also have landing legs (implies attempt at flyback to land, not ocean — today’s flight must have inspired confidence).

I mistyped above. The second stage didn’t shut down prematurely, it had a problem with restart. But I think it was just a test of the vehicle, and didn’t affect the primary mission.
