  1. Re:Shuttle did NOT survive unmodified on USA To Return To Moon By 2015, Then Mars · · Score: 1

    I am also concerned that this announcement will drain all remaining funding from the current unmanned exploration programs

    I was worried about this to, but Bush mentioned in his speech that robots would pave the way for manned missions. So it sounds like at least some of the unmanned exploration will continue. I don't know what it means for the telescopes and things of that nature. (I think, seeing the reaction to the Mars Rover, that the best thing NASA could do for itself is build that multiple-satellite planet-finder telescope that's still in the design stage. Once we start finding Earth-sized Earth-like planets out there, the government will be forced to fund the space program like it does the Pentagon.)

  2. Re:Reflecting on the prior article on USA To Return To Moon By 2015, Then Mars · · Score: 1

    techno-vampire might have been overly optimistic. It is possible that the program might become so popular it would be political suicide to cancel it. There's a lot of excitement about the Mars rovers, and space travel is a lot more important to the average voter than supercoliders (which, I am assuming, average people considered a barely justified expense when they thought about it at all).

    That being said, Bush didn't say much that hasn't been said and then quietly not-acted-upon, before. Since he didn't plan to allocate any more money to the program ($1 billion over 5 years is something like a 1% budget increase), I'm doubt that anything is going to happen at all.

    However, the timing of his speech may have unexpected effect. The Mars Rover has been a publicity bonanza for NASA, and people may hold Bush to his word because they're excited about what's going on already. Also, the Democratic candidates will probably feel compelled to come out with their own "space plans" and will at least have to go on record with what they think should happen. So, there will be some discussion about it, at least as long as the Mars Rover missions are still working. Maybe that will give the whole idea of being serious about space enough momentum that it will become politically important to keep the space plan (whatever it ends up being) going.

    On the whole, though, I wasn't particularly encouraged by what Bush said. I was half hoping that his pro-business credentials would get him to promote a deregulated space market. But, that will probably take a few more years (and some X Prize success) to become a viable option.

    Yeah, it's a problem. Bush is so much more attractive than Dean to conservative voters that he can do almost anything he wants (too easy on the environment, not enough attention to health care or education, a barely defensible economic policy) and we'll still vote for him. I think if Dean gets the Democratic nod, Bush will have so little to worry about as far as re-election is concerned that he won't change his position at all. So I'm really hoping that the Democrats field a strong candidate. Even if I still end up voting for Bush (his performance against terrorists is hard to beat), a strong competitor will force him and the Republicans to improve on areas that they've let slide in the last few years.

    As Politburo was saying, it's early yet...

    The nice thing about these space promises (if and when he makes them), is we'll get to see him act on them before the election. The problem is, of course, that no politician (yet) has been severly hurt by making promises about space and then not delivering. Some day it will be a real issue....

    Thinking it over a bit, I'm pretty close to an indefensible position. It is too close to election time for it to be entirely believable that this was simply something Bush woke up one morning and decided to do. Also, presidential candidates are notorious for touting space-related goals during elections and ignoring them from then on. Us space-geeks are a gullible bunch.

    However, I think it's plausible, judging from Bush's other actions, that he's not simply dangling this out there and hoping the voters will be swayed by his leadership. Also, I don't get the impression he really cares too much about the political race yet (that's where the polls come in: sure it's early, but he's got no worries yet). I don't think I could give factual support for either of these statements without a lot more work than I'm willing to put forth at the moment. So, unless you really want me to defend these, I'm just going to let it go at that.

    It's hard to judge a candidate's motives when he does something right. Is he doing the right thing because he believes in it, or is he just trying to appease the electorate? And, for promises like this, do you trust him to keep them? Because Bush tends to do what he says he's going to do, if he says we're going to Mars, I'm going to trust him somewhat. Enough to vote for him next year? Not soley on his space-credentials, but it's a plus.

    You're not going to believe this, but some of us actually do believe that Bush is a visionary.

    The most recent example: immigration laws are really screwed up, especially with regard to Mexico. Most Republicans want to be tough on immigration. However, Bush stood up and said immigration needs to be changed.

    Other examples:
    The Freedom Car (almost too visionary for my taste).
    Following a defense policy of pre-emption instead of waiting to be hit by terrorists (you might disagree with it, but it's a completely different defensive stance than we've had before. The closest thing to it was when Roosevelt used the navy to protect England before officially entering WWII).

    He may be wrong, but he's got ideas (or, in the case of pre-emption, he's got good advisors) and he's not afraid to talk about them.

    This isn't an election-year ploy for the simple reason that Bush is not running for election yet. He doesn't have to. I haven't seen a poll yet that says he's in danger of being beaten by a Democrat. The Democrats are busy campaigning against each other and tearing each other down.

They are attempting to get nuclear capability.

    Nuclear capability is almost uncontrollable now. Almost, but not quite. The US has every reason to deal swiftly and decisively with hostile nuclear nations. Because if Iran or North Korea get nukes, the US is much, much more vulnerable.

    Because of the danger of anonymous, nuclear strikes by terrorists, a country hostile to the US can't simply have nukes as a defensive measure. The US will see that country as an immediate threat. If you're a small tyranny, you don't want the US considering you a threat these days.

    A lot of the intelligence the forces have been getting is from guys coming in off the street saying that they know where a certain Baathist is hiding. This isn't the most valuable kind of intelligence, (after all, the civilian could just be trying to settle a score with his innocent neighbor) but it has some value, and it's helpful in setting a context for more valuable tips that aren't obviously connected. The generals said today that they expected a lot more intelligence to come in after this capture. This isn't because they expected Saddam to start telling all his secrets (they said that they expected to learn nothing from him), but they expect more civilians to help them now that they have less to fear from the possibility of retribution.

    Every time an Iraqi tips of the coallition forces about a Baathist, that Iraqi is risking his life. The more Baathists caught, the less risk, and the more people willing to contribute, and the whole process snowballs. The more high-profile the capture, the better response from the man-on-the-street. So, an "Iraqi guy tipping them off" is an indication of the improving intelligence capabilities.

    On a related note. The Iraqis marching against terrorism last week were risking their lives. Naturally, considering the terrorism that is going on right now, the marches weren't all that big. But, if they live the month and hold another march, more people will join them. Same idea.

    The fact that the US hasn't invaded a country with nuclear capability is an accident of history at this time. MAD worked pretty well when there weren't many countries with nuclear capability. Now, with Iran and N.K. both attempting to achieve nuclear capability, it is very likely that the US will invade a nuclear country in the near future. There is no way to effectively deter terrorists or unstable countries from using nuclear weapons.

    The current policy of the US seems to be to consider invading unstable, hostile countries before they go nuclear if possible (that was one of the arguments for invading Iraq--Iraq was trying to get nuclear capability). With N.K. and Iran, it may be that the US discovers that they have nuclear capability after the fact. They may plan to invade these countries because of their budding nuclear capability.

    Because of these nations' sponsorship of terrorism, we would need to strike them before they had nuclear weapons, or, barring that, before they had a significant number of nuclear weapons, in order to protect our coastal cities from nuclear shipping cargo.

    I know that Pakistan almost fits into the same category as Iran and North Korea, but we're hanging on to the thread of hope that it's stable enough (and the army will continue to be friendly enough), that it isn't a threat.

    North Korea may be safe from invasion for a while because it could take Japan or South Korea down with it.

    Iran is not safe. If it continues to pursue nuclear capability, and the IAEA continues to act like the UN did with regard to Iraq, it Will be bombed soon. Either by Israel, or the US, or both. And if you're going to bomb that country's army to destroy it's nuclear capability, might as well push it up a notch or two to destroy the mullah's power completely and free the people, right?

It is true that this doesn't prove the US is any further along in their pursuit of Islamic terror cells in Iraq, but use your head. If the US can get inside the workings of the Ba'athists, who have a long-entrenched network and blood ties to the region, they are probably doing ok with a bunch of foreigners who are lost in the country without the help of Ba'athists.

    Sure, the terror isn't over, but the US is getting inside these groups. Every time they make a capture like this, more civilians are emboldened to report terrorists in their neighborhood. Every time they capture or kill a leader, more Islamic teenagers think that maybe, just maybe, their psychotic Imams are wrong when they assure them the American is weak and will be easily be cowed by the passion of the jihadis.

This is like complaining that goes on on this site when money goes to scientific research instead of doing nice things like feeding the poor; things aren't perfect, but that doesn't change the fact that this is a good thing.

It's less likely that the Afganistan troops will be successful, but here's hoping.)

Also, before the war Saddam was a major source. We knew that, and we stopped it. Hopefully someday we'll stop the Saudis from contributing as well.

If the moon base succeeds, his name will (should) be associated with it historically. If it fails, the funding will be quietly cut by some future administration, the government subsidies will have gone to nothing, and the man to blame will be out of office already and not bear the consequences of his poor investment. It's unlikely that his place in history will be diminished by a failed space program (look at Bush Sr.'s plan mentioned in the National Review article.
