Well, it seemed like a good idea...
Last Thursday, as most expected, Boeing announced it had selected United Launch Alliance’s Atlas 5 rocket to launch its CST-100 commercial crew vehicle, at least for a series of three test flights in 2015. (John Elbon, Boeing’s program manager for the CST-100, said that the company would recompete launches for the operational CST-100 missions, if funded, although barring any problems ULA would seem to have the inside track in that recompete.) The announcement, though, did offer some insights on Boeing’s plans and thoughts about NASA’s Commercial Crew Development (CCDev) program in general.
Of the three test flights using the Atlas 5 (a fourth will be a pad abort test that won’t require a launch vehicle), only one will be crewed: the last flight, which will place the CST-100 in orbit to rendezvous with the ISS. Elbon noted that two Boeing test pilots would fly that mission. Boeing hasn’t hired any test pilots, but Elbon said that they were in the process of selecting their first, who would participate in the CST-100 development to provide a pilot’s perspective. “We’re just starting the interview process,” he said. “Of course, it’s interesting to look at flown astronauts as candidates for this, and certainly we’ll consider that as we make selections. They could also be test pilots, maybe, that haven’t flown in space, or some mix of all that.”
Boeing isn’t the only company to select the Atlas 5 for commercial crew launches: two of the other three CCDev-2 awardees, Blue Origin and Sierra Nevada Corporation, also have proposed launching their spacecraft on that vehicle. (SpaceX, of course, plans to use its own Falcon 9 for its crewed Dragon spacecraft.) George Sowers of ULA said part of the contract with Boeing covers work on the Atlas 5 launch site at Cape Canaveral to allow for crew access in and out of the vehicle on the pad. That work, Sowers noted, would not be specific to the CST-100 but could also support Blue Origin’s and Sierra Nevada’s vehicles. “Our preference is to have something that we could attach to the existing mobile launch platform, and not have to build a dedicated tower or gantry,” Sowers said.
Elbon also touched upon other burning issues regarding CCDev: the contracting mechanism and funding for the program. Last month NASA officials said they were tentatively planning to shift from a Space Act Agreement (SAA) to a contract that would still have some of the features of an SAA but also adhere to Federal Acquisition Regulations (FAR). That has generated an outcry of opposition from many companies, concerned about being overwhelmed with contracting bureaucracy and worried this could be a first step towards moving to traditional cost-plus contracts.
Elbon took a more nuanced view to the debate. “I think it’s unfortunate that the debate is centered around the contract mechanism and is not focused on the attributes that whatever mechanism is put in place needs to have,” he said, adding that he believes an SAA-based or FAR-based approach can be successful if those attributes are there. The biggest issue, he said, is who is responsible for design decisions: “The design decisions in this current environment rest with us as the developer,” he said, referring to the SAA-based CCDev-2 award Boeing currently is working out. ‘We can move much more rapidly through the design process by being able to make those decisions internally and not go through a series of boards and panels that vet things in the NASA system and then work contract changes to cause those things to happen.”
Another issue, he said, is ownership of the intellectual property (IP) involved in the development effort. “If truly our objective here is to develop a commercial market, it’s important that we retain the intellectual property so that we can use that vehicle for other purposes” beyond flying NASA astronauts to and from the ISS, as well as to keep that IP out of the hands of potential competitors.
“The debate really needs to be centered on what those things are and figuring out how to carry those things going forward,” he said of the key attributes for CCDev contracts. “I’m really disappointed in the direction that the debate took in the press conference” that unveiled NASA’s plans last month.
Regarding CCDev funding, Elbon expressed concerned about potential FY2012 budget cuts. What’s in the president’s budget request—$850 million a year from 2012 through 2016—is “in the neighborhood of what it would take to make this program successful,” he said, “so I would hope Congress would consider funding the program at or near those levels.” However, the House is proposing only $312 million for CCDev in 2012 in its appropriation bill awaiting consider by the full House. Funding has already had an effect on Boeing’s plans: Elbon noted that their initial test flight plans “was based on a different level of CCDev-2 funding that we received,” causing the company to push back its test schedule slightly. “There’s been about a quarter’s worth of impact due to the funding that came out of CCDev-2 as we went forward.”

Standard & Poor’s director said for the first time Thursday that one reason the United States lost its triple-A credit rating was that several lawmakers expressed skepticism about the serious consequences of a credit default — a position put forth by some Republicans.
Without specifically mentioning Republicans, S&P senior director Joydeep Mukherji said the stability and effectiveness of American political institutions were undermined by the fact that “people in the political arena were even talking about a potential default,” Mukherji said.
“That a country even has such voices, albeit a minority, is something notable,” he added. “This kind of rhetoric is not common amongst AAA sovereigns.”
I’ve been critical of S&P’s reasoning. The ratings agency itself has a lot to answer for and doesn’t strike me as very credible. But honestly, this more forthcoming political rationale for a downgrade makes a lot more sense than anything else I’ve heard.
I used to think global warming denial was the most alarming example of motivated reasoning in our politics. But maybe not. Denying what can at least be made to appear a longer term threat is one thing. Denying the idea that a credit default would be immediately devastating, or arguing that it would be manageable or even desirable, strikes me as an even more extreme concoction and rationalization.
I’m also still waiting for the Onion headline: “S&P Downgrades Earth; Cites Unbalanced Carbon Budget.”

The Seasteading Institute - July 2011 Newsletter
Greetings Friends of Seasteading,
Our vision for seasteading is to improve government through competition, and my personal talents lie in seeing possibilities and starting initiatives. Many groups and organizations in the past have tried their hand at the audacious task of creating innovative societies, and I saw the possibility for seasteading to powerfully advance this idea with our unique approach. Thus was born The Seasteading Institute in 2008, as a marvelous addition to the practical politics portfolio.
Much important movement-building and research work remains here at the Institute, and we believe there is also important work to be done in the commercial sector, by creating businesses that benefit individuals through better laws. From both a personal and organizational standpoint, the time is right for me to pursue the vision of government innovation by shifting my primary focus to creating new commercial ventures that will complement the work here at the Institute. I look forward to sharing more details about my projects as they become more solid.
I’m excited to announce that I've found a great executive team to take over and continue to grow The Seasteading Institute: Michael Keenan and Randy Hencken. I will stay significantly involved as Chairman of the Board, media and diplomatic spokesperson, and strategic advisor, as well as promoting seasteading through our in-progress book Seasteading: How Ocean Cities Will Reinvent Politics. While it is a bittersweet moment for me, I believe my talents are best suited to continuing to expand our portfolio of ventures, while Michael and Randy have the passion and talent to take The Seasteading Institute to the next level.
Similarly, two other staff members—Max Marty, Director of Business Strategy and Dario Mutzabdzija, Director of Legal Strategy—are wrapping up their research and preparing to start Blue Seed, a shipsteading venture, as their contribution to expanding the movement. A commercial sector is vital to seasteading progress, and so we’re thrilled that Max and Dario are helping lead the charge to this next frontier for seasteading, and we’re excited to see where their adventure takes them.
As you can see in this newsletter, we have lots of great progress to report, and Michael and Randy will continue to add new programs to advance the seasteading mission. If you’re interested in reading about the details of our motivation for this expansion, the staff and program changes, and the new ventures, this page has more information.
In service of seasteading,
Patri Friedman
