I Have To Confess

I have never thought of Lori Garver as a snow princess.

Will she be the next administrator, though?

I also have to say that I found this comment disturbing:

Seems highly likely Orion will become ISS only for now.

Let’s sincerely hope not. That would be a major blow to commercial services. Better to just end it, and ramp up COTS.

[Afternoon update]

She’s married, with kids. Shouldn’t she be the Snow Queen (not to be confused with the Ice Queen)?

Not Just A Wind Problem

There’s a good article over at NASA Spaceflight on the lift-off drift problem of the Ares 1.

Safe, simple, soon. Scam.

[Update a couple minutes later]

More at the Orlando Sentinel, on the Congressional Budget Office finding that the vehicle can’t hit its IOC date without billions more. And there will still be a gap.

Billions of dollars to develop a new vehicle we don’t need, when we could have been flying something by 2010 or 2011 with Steidle’s original plan.

It’s Getting Harder And Harder To Surprise

The Orion spacecraft program was reviewed with the wrong configuration. There’s more here:

So an older, immature design of the Orion capsule is brought up for review and passes muster, when it fact it lacks many of the features a flight worthy capsule would have (e.g., a weight that would be liftable, a means of landing that won’t kill the occupants) along with several that a real vehicle wouldn’t have (e.g., extra amounts of hot water for BroomHilda’s cauldron).

That’s not the way the process is supposed to work.

Unfortunately, the IG’s office, not known for their brilliance or their ethics, took the ESMD Viceroy’s non-concurrence with their findings and said, “ok, so sorry to have bothered you,” and moved on.

Can’t anyone here play this game? How much longer before this misbegotten program augers in?

Government Space Programs

Clark Lindsey points out the inherent problem:

I’ve certainly always believed that NASA can get anything to fly with enough time and billions of dollars. The issue is cost-effectiveness. This vehicle, which is obsolete for the 20th century much less the 21st, is simply not going to pay off in terms of making space exploration cheaper or safer.

Ignoring its gigantic price tag for the moment, if Ares I were just one of several competing commercial rocket vehicle projects funded in a COTS type of program, I have no doubt that NASA would have been canceled it long ago just on technical grounds and missed milestones. Unfortunately, when a large project is developed internally, it becomes virtually impossible to stop, especially in a case like this where the top management is so deeply invested in it. The next administration might take another look at Ares but unfortunately the battle for Florida votes has left both candidates committed to it as a jobs program. Such is how a promising vision for space exploration finds itself hung by a boondoggle.

While I agree, I have to say that the last sentence sounds painful. And at least psychically, it is.

Don’t Know Much About Launch Costs

The Space Review is up (a little late–it’s usually available first thing Monday morning, but Jeff is probably recovering from his trip to New Mexico), and it has a couple interesting articles. The first one describes the benefits of amateur efforts toward space settlement. The second one is a relook at the economics of O”Neill’s Island One space habitat. It’s nonsensical, because the author doesn’t understand much about the economics of space launch. Let’s start with this:

O’Neill’s expectations about launch costs (like those of other 1970s-era prophets of space development) proved to be highly optimistic, even given the disagreement about how these are to be calculated. A $10,000 a pound ($22,000 per kilogram) Earth-to-LEO price, almost twenty-five times the estimate O’Neill worked with, is considered the reasonable optimum now.

Considered so by whom? Not by ULA. Not by the Russians. Not by SpaceX. The only launch vehicle that has launch costs that high is the Shuttle, and that’s because it flies so seldom that its per-flight cost is on the order of a billion dollars. In a due-east launch, it can get close to sixty thousand pounds to LEO, and if it cost six hundred million per flight (as it did before Columbia, when the flight rate was higher), that would be about ten thousand bucks a pound. But to call this “optimum” is lunacy. Other existing launchers are going for a couple thousand a pound (the Russians are less based on price, but its not clear what their costs are, and if they’re making money). SpaceX is projecting its price for Falcon 9 to be about forty million, to deliver almost thirty thousand pounds to LEO, so that’s a little over a thousand per pound. And that’s without reusing any hardware.

But even these are hardly “optimum.” The true price drops will come from high flight rates of fully-reusable space transports, and there’s no physical reason that these couldn’t deliver payload for on the order of a hundred dollars per pound or less.

Of course we aren’t going to build HLVs for space colonies, as Gerry O’Neill proposed. If it happens, it will happen when the price does come down, as a result of other markets. But if the point is that Island One is unaffordable at current launch costs, it’s a trivial one–most intelligent observers realize that. But it’s ridiculous to think that lower launch costs can’t be achieved, or even that his stated number has any basis in reality.
