Apollo Anniversary Thoughts

Nothing has happened since the fortieth anniversary to change my opinions in the long essay I wrote last summer.

Four decades have passed since the first small step on the dusty surface of our nearest neighbor in the solar system in 1969. It has been almost that long since the last man to walk on the Moon did so in late 1972. The Apollo missions were a stunning technological achievement and a significant Cold War victory for the United States. However, despite the hope of observers at the time—and despite the nostalgia and mythology that now cloud our memory—Apollo was not the first step into a grand human future in space. From the perspective of forty years, Apollo, for all its glory, can now be seen as a detour away from a sustainable human presence in space. By and large, the NASA programs that succeeded Apollo have kept us heading down that wrong path: Toward more bureaucracy. Toward higher costs. And away from innovation, from risk-taking, and from any concept of space as a useful place.

As I wrote, Apollo was a magnificent technological achievement, but in terms of opening up space, it was not only a failure, but the false lessons learned from it have held us back ever since.

The History And Future Of Space Exploration

I missed my connection to LA, and am stuck in Chicago until I can find a flight some time tomorrow. It’s kind of late, and I don’t have much time for blogging, and many of you may have already seen it, but Glenn Reynolds has a piece on space exploration in the Journal tomorrow. And of course, Tuesday will be the 41st anniversary of the first steps on the moon. It’s not too late to plan a party to celebrate. I and the co-author, Bill Simon, will be on The Space Show that evening. We may even do a live version of the ceremony, though that’s still TBD.

Flying On Its Own?

I’m getting well-sourced indications that the first SpaceShipTwo drop test will occur today, and that they’re taxiing in Mojave.

They may be having problems. The vehicle is reportedly out on the apron, but all the engines have been shut down.

Well, whatever the problem was yesterday, they seem to have fixed it.

An Urgent Call To Action

Thoughts on tomorrow’s Senate vote on NASA authorization, from Henry Vanderbilt of the Space Access Society:

…let them both know that you support full funding for NASA Commercial Crew, and full funding for NASA space exploration technology, and that you are very much against any new NASA heavy lift booster development as very likely being a massive waste of taxpayer dollars.

Read the whole thing.

[Thursday morning update]

Clark Lindsey has some links to the latest on the bill, here, here and here.

He also has some thoughts on how it could have been a lot worse:

while I don’t want to sugar-coat this awful bill, I’m just saying that it is no cause for despair. My philosophy from the start of this website and blog has been based on a belief that progress usually comes in step-by-step increments. It will be disappointing if the 2011 NASA budget doesn’t make the huge step initially promised. Nevertheless, even this bill is a step forward.

I never have high hopes for space policy. The bill could be a lot better, but just getting rid of Constellation, and particularly Ares, is a huge improvement. I’m willing to take if for now, and start to educate the Republicans so we can get better policy when they take over next year, and hope that they don’t try to undo everything that Obama did, and restore the disastrous Bush policy, simply on partisan grounds. It’s important to have a serious discussion on what we’re trying to accomplish, and how best to do it, regardless of the genesis of various policies. It hasn’t happened yet, but hope springs eternal.

No word about the press conference yet, but here is Hutchison’s official statement.

Saving Private CRuSR

Apparently, among the many other idiotic things that the Senate authorization draft does is to kill the CRuSR program, the NASA initiative to encourage more suborbital science, which will be helpful in growing the industry. There is an effort afoot to fix this.

John Gedmark of the Commercial Space Federation is sending out an alert:

URGENT: Commercial Space in Jeopardy — Call Your Senator TODAY

A new authorization bill for NASA includes major cuts to commercial spaceflight, but Senator Warner has offered an amendment to restore those cuts and move commercial space forward.

The NASA Authorization Bill being proposed cuts the proposed Commercial Crew Program by $2.1 billion (up to 66%), seriously affecting commercial space efforts by such companies as SpaceX, United Launch Alliance, Sierra Nevada Corporation, Boeing, and Orbital Sciences. Senator Warner’s amendment will restore full funding to the program, but he needs YOUR help to get support from other Senators!

The Warner Amendment will be voted on Thursday morning. Now is the time to call your Senator to say, “Please support the Warner Amendment for commercial spaceflight that will create over 10,000 jobs, and reduce our dependence on Russia!” This is your chance to make a difference in the course of space history! (The phone numbers for each Senator on the committee are below, so please check to see if you or your parents are a residents of one of those states!)

Another Blow To The Space Policy Myths

Some people have been counting on the CAIB to support their nonsensical assertions about safety of government versus commercial vehicles. Well, they’re out of luck:

Our view is that NASA’s new direction can be a) just as safe, if not more safe, than government-controlled alternatives b) will achieve higher safety than that of the Space Shuttle, and c) is directly in line with the recommendations of the CAIB.

Just one more nail in the coffin of space policy mythology. There may be good arguments against the new plan, but for the most part, for the past few months, most of the ones I’ve seen have been both tragic and hilarious in their illogic and non-factuality.

[Update a few minutes later]

In reading the whole thing, I think they’re being far too kind (though I understand that they have to be diplomatic):

Second, the CAIB recommended that future launch systems should “separate crew from cargo” as much as possible. This statement is sometimes taken out of context. What it does mean is that human lives should not be risked on flights that can be performed without people; the new plan to procure separate crew and cargo transportation services clearly is consistent with the CAIB’s recommendation. But the recommendation does not disallow the use of a cargo launch system to also fly, on separate missions, astronaut flights. Indeed, the fact that Atlas V and Delta IV are flying satellites right now, including extremely high-value satellites, has helped to prove out their reliability. And the many satellite and cargo missions that Falcon 9 is planned to fly will also produce the same beneficial result.

This is a very important point. First, that people have always misunderstood the “separate crew and cargo” lesson. To the degree it ever made any sense at all (we don’t do it for trucks, or airplanes), it never meant to have different vehicle designs for crew versus cargo. And one of the craziest notions that the Ares defenders had was that it would be “designed” to be so safe that crew could fly on it on its second flight, whereas rockets with a proven record of dozens of consecutive successful flights under their belts were somehow less “safe” than one with only one flight. As the CSF pointed out today:

The demonstrated track records of commercial vehicles, combined with numerous upcoming manifested flights, means that the family of commercial vehicles already has, and will continue to have, a much stronger track record than other vehicles such as Ares I. The Atlas family of rockets has had over 90 consecutive successes including 21 consecutive successes for Atlas V, and additional unmanned flights will occur over the next few years before any astronaut flights begin. Similarly, many flights of the Delta and Falcon vehicles have already occurred or will occur before astronauts would be placed onboard. Astronauts will not be flying on vehicles that lack a solid track record.

By contrast, NASA was planning to place astronauts on just the second full-up orbital flight of the Ares I system. Ares I would have many fewer test flights than Atlas V, Falcon 9, or Delta IV. Furthermore, the first crewed flight of Ares I will not occur until the year 2017 as determined by the Augustine Committee. Thus, at the planned rate of two Ares I flights per year, it would take the Ares I rocket until at least the year 2025 to match the demonstrated reliability that the Atlas V rocket already has today. That is, the commercial rocket has a fifteen-year head start on safety.

Demonstrated reliability through multiple actual flights to orbit is crucial because paper calculations have historically been insufficient to capture the majority of failure modes that affect real, flying vehicles—especially new vehicles flying their first few missions. As the Augustine Committee stated, “The often-used Probabilistic Risk Assessment (PRA) … is not as useful a guide as to whether a new launch vehicle will fail during operations, especially during its early flights.” Demonstrated reliability is crucial.

And it’s something that would have taken decades for Ares to develop, given its horrific costs and low flight rate.

And then it’s nice to see people with these credentials dispense with this nonsense:

It has been suggested by some that only a NASA-led effort can provide the safety assurance required to commit to launching government astronauts into space. We must note that much of the CAIB report was an indictment of NASA’s safety culture, not a defense of its uniqueness. The report (p. 97) notes that “at NASA’s urging, the nation committed to build an amazing, if compromised, vehicle called the Space Shuttle. When the agency did this, it accepted the bargain to operate and maintain the vehicle in the safest possible way.” The report then adds, “The Board is not convinced that NASA has completely lived up to the bargain.”

To put it mildly. And there’s no reason that it would be any different in the future. The institutional incentives haven’t changed, and never will, with a government-run program. Private industry has a very strong motivation not to kill people — it could put them out of business. Government agencies, on the other hand, tend to be rewarded for failure.
