How Far We’ve Come

Back before the 2004 election, there were rumors that the Bush administration was considering withdrawal or renegotiation of the 1967 Outer Space Treaty, which briefly encouraged me. Alas, the pebble disappeared into the pond with nary a ripple.

Now, apparently the administration is instead pushing the Law Of The Sea Treaty. Andy McCarthy is appropriately appalled:

Our current threat environment, coupled with the abysmal performance of international institutions, cries out for a re-thinking all these multi-lateral commitments. Negroponte and England’s claim that we need to ratify LOST in order to demonstrate our commitment to “the rule of law” is absurd. The American people, who do more for the people of the world than any nation in history, have a rule of law; it is known as the Constitution. It allows us to make agreements as needed with nations based on our mutual interests (and it is worth noting that most of the benefits under LOST are already honored under other treaties and international law

Wrong Lessons Learned

In light of the latest assembly mission to the ISS, Clark Lindsey points out one of the many absurdities with the ESAS approach:

I’ve noted before that I find it odd that a fundamental goal of the Constellation project design is to minimize in-space assembly. This is a task in which NASA has actually become quite good. If NASA went to the next stage and combined its in-space operations capabilities with fuel depots and a space tug, it would have the tools and skill sets to do some amazing stuff, especially if it worked in close cooperation with private ventures like Bigelow.

Unfortunately, as with building Ares 1/5 instead of using existing (e.g. EELV) or nearly ready vehicles (e.g. Falcon 9, K-1), the aim seems to be to time warp back to 1972 and continue on to Apollo II, ignoring much of what was learned and developed subsequently.

Indeed.

Ares In Political Trouble?

This wouldn’t surprise me, if true:

No one seems to be all that fond of continuing the development of Ares 1 (a government-owned solution) or the cost of developing something that already exists i.e. something you can buy now (EELVs). Of course, much can change between now and the election – and who will run NASA in 2009. But the writing on the wall is starting to become rather clear.

Space Prizes Continue To Get Interest

This isn’t really a surprise to anyone familiar with him and his history, but Newt Gingrich is continuing to promote prizes for space achievements. I agree with commenters that his proposal of twenty billion for a human Mars mission is a prize too far, not just for all the reasons stated (too much money to raise privately, too long-term a proposition, too little faith in the government to keep its word) but also because I’m not sure that there would be adequate public support for the goal itself. A more incremental approach is indeed required–going from a ten million dollar prize to a twenty billion dollar prize is just too much of a leap.

I also agree with this comment, with a caveat:

IMO, we should start with smaller prizes. I would create three (3) prizes, in the following order: 1) orbital RLVs, 2) LEO propellant depots, and then 3) Processing oxygen on the Moon, and 4) Delivering the oxygen from the lunar surface to a LEO prop depot.

I suspect that it will be a long time before it’s economically viable to deliver lunar LOX to LEO, at least directly. What I would envision happening is a LEO depot, an EML1 depot, and a continuous parade of low-thrust tankers (which might also serve as the depots themselves while in place) moving back and forth between the two locations, delivering propellant to wherever the price dictates. If the tankers could deliver lunar LOX to LEO at a lower cost than delivery from earth, then they would do so. If it only made sense to use lunar LOX one-way as propellant to leave the moon, and it was cheaper to refuel at EML1 for the return using LOX delivered from earth, then that’s what should happen. The important thing is to establish the propellant supply infrastructure, regardless of the source of propellants. Building roads and a gasoline-delivery infrastructure was critical to making reusable cars (as opposed to the one-way Conestoga wagons) practical, and we need to do something similar in space.

Saw The Launch

We watched it from the causeway west of Cocoa Beach. It was a beautiful evening for it–all of the clouds had cleared. I may put up some pictures tomorrow, if they look worth it. Off to bed now, a little after 1 AM.

Welcome, Lord British

In the non-space publication PC Gamer in the July issue, we find that video game celebrity and fellow Austinite Richard Garriott will have a regular column where we will find out about his PC Games from NC Soft like Tabula Rasa and also “what one says to Stephen Hawking while riding the ‘vomit comet.'”

While technically he rode ZEROG non-vomit comet with only 12 parabolas (which doesn’t give me much hope for the space editing in the magazine), Garriott’s space persona includes being Vice Chairman of Space Adventures, the company that has the most space tourism cost of goods sold. He is also the son of astronaut Owen Garriott.

So welcome, Lord British! And keep up the good work bringing science fiction to digital–and analog–life.

I Have To Laugh

Mark Whittington reads a prognosticative puff piece by various NASA officials, and thinks that it’s somehow a rebuttal to all the critics of the program.

What do you expect, Mark? That they’re going to say it’s not going to survive? It’s not like any of them are going to be around and accountable six years from now. Is there anything they could tell you that you wouldn’t believe? Did you know that the word “gullible” isn’t in the dictionary?

Well, at least he admits his confusion.
