It’s A Start

4 Comments

We’re finally starting to take the asteroid threat seriously enough to start dedicating new telescopes to looking for them. A hundred million dollars seems like a pretty cheap insurance policy against another Tunguska or worse, in a populated area.

Unfortunately, we’re not developing the kind of spacefaring capability we need to do something about it if we see one coming. This is one kind of change that I’d be happy to see with the incoming administration. But it remains to be seen what space policy will come out of the process.

Good News, If True

I had suggested this to some people on the transition team, but I’m sure I wasn’t the only one. It looks like the Ares V RFP (and perhaps others) that was going to ruin (as is often the case) the contractors’ holidays with the need to work a proposal, is being postponed (and perhaps going away altogether — we can only hope). It’s a waste of money and contractor resources to force them to bid on a Phase I of a program that’s under review as to whether it should exist at all. Clearly, as noted over at R’n’S, Mike was trying to rush these things to entrench them and make them more of a fait accompli before he leaves, and fortunately, the incoming administration is having none of it.

I’m not sure how that worked, exactly, since they don’t actually have any authority until January, but (just as a guess) if I had been them, I would have told the contractors that I had no intention of funding the program without (at a minimum) a requirements review, which would imply (at a minimum) a rebid, and hope that they would in turn tell NASA that no one would bother to bid now.

Making Our Own Leaves

Here’s an interesting piece on breakthroughs in artificial photosynthesis. My biggest problem with it is that it talks about hydrogen as being “easy to store,” but it doesn’t describe in any way how this is done. Clearly, if you don’t have to carry it in a vehicle (as would be required for transport fuel) the job is a lot easier, but it’s still non trivial. If it’s simply for load leveling, you have a lot more options, but they still come down to three: hydrides, high-pressure gas, or liquid. The latter uses a lot of energy to chill it, and loses it in rewarming.

There is a picture of a notional system in a garage, but it shows a water tank, hydrogen tank, and oxygen tank, and the separated gases (or liquids?). The water tank looks like about half the volume of the separated elements. How realistic is this? What is going on? I’d expect more from an article in Technology Review.

News I Can Use

Sort of.

I had my eyes checked last week (for the first time in three or four years) and discovered that I’m color blind. Sort of. It’s minor enough that it’s never been an issue from a functional standpoint, apparently, and this is the first time that I’ve ever had this problem diagnosed. I went on line to check out some of the tests to confirm it, and I do show up as red-green color blind, but only mildly. That is, I can sometimes make out the things that normal sighted are supposed to see, but some of them just barely very dim, and I can see some (but not all) of the numbers that true red-green color blind people aren’t supposed to at all. On the ones that have one number for normal, and a different one for color-blind, I see the color-blind one more clearly, but I can actually see both. And I’ve never had any trouble distinguishing red from green traffic lights (which would be the biggest problem, I would think, though fully color-blind people know from position). When I look at the pictures that show what the world looks like to normal and deficient eyes, I can very clearly see the vivid red dress as red, whereas it should be more of a greenish color if I were fully color blind. I wonder what this page looks like to someone with no red receptors? Are both pictures the same? And it makes me wonder what the red dress would look like to someone with normal vision (something I’ve never wondered before, because I’ve always thought I had normal vision).

So, the question is, have I always had this borderline condition, and it’s only become apparent now, or was I much better in my youth (I never failed a test as a kid) and have deteriorated a lot with mileage? I’m guessing that maybe I was always borderline, but far enough over the border toward normal earlier that I always passed the test, not realizing that I could have been seeing the numbers more clearly had my color sight been better, and perhaps with age, I’ve drifted into a region where I don’t fully pass any more, but am still a long way from being unable to distinguish red from green.

Anyway, the opthalmologist recommended a follow-up visit to a neuro-opthalmologist, just to make sure that there wasn’t something else going on (just as a precaution, because it’s unlikely that it’s caused by anything serious).

GM’s “Business Plan”

5 Comments

Manzi is on the job, deconstructing it. Bottom line:

…this is not a real business plan, but simply a political document. It exists to provide political cover to members of Congress. But if that’s the case, it’s an unintentionally beautiful illustration of why industrial policy fails. It’s both economically crucial and very hard to allocate capital well; that’s why people who are good at it make so much money. Businesses struggle to do this well, and they’re really trying. What do you think the odds are that this is a wise use of money, when the people involved are barely pretending to try?

All this is doing is kicking the can down the road, and delaying (and making much worse) the inevitable and painful restructuring that has to take place. And I’m not talking about just GM, or the auto industry.

Safe, Simple, Soon

Now, the “off-the-shelf” five-segment first stage for the Ares 1 is going to a new propellant formulation, for environmental reasons. No, that won’t take long or cost much to develop or test. And apparently we don’t even have the capability in country to do it currently — we have to rely on the Swedes.

If they were worried about the environment, they shouldn’t have gone with a solid in the first place.

How long before this monstrosity is put out of its (and our) misery? They need to just take the whole concept out behind the VABarn and put it down with a sledge hammer.
