I like dobs, you get more aperture for the buck and they are extremely simple to setup.  And I find them perfectly comfortable to use.  I'd only use an EQ if I was into astrophotography.  As for tracking, on most deep space objects you will be using relatively low powers anyway so tracking is a non issue and I find tracking on planets isn't really much of a problem either.

#102 Re: Meta New Mars » Other forums on space exploration? » 2003-07-28 18:55:32

There's a brand new forum at the X-prize site.  They didn't want it publicised yet but you can find it herebig_smile

There's also a new forum at spacedaily.com, the link is near the top lefthand corner of the page in green letters.  I haven't actually registered on that one yet but plan to.

Cool website, here's their NEAP article.  I also went to Spacedev.com but the details they put up are sketchy.  Well at least the project is still posted on their site so maybe NEAP hasn't died a long, torturous death.

#104 Re: Science, Technology, and Astronomy » Mars 11 Earth 4 - hostorically Mars is a hard nut to crack » 2003-07-27 20:26:24

Spooky alright.  They should load up the Pluto Express probe with instruments to study the phenomena (maybe slap an extra RTG on there big_smile .)

#105 Re: Other space advocacy organizations » Space Industrialization - Should a massive attempt at mining occur » 2003-07-27 20:11:08

Has anyone heard about project NEAP (Near Earth Asteroid Prospector) probe?  I'd like to know if this thing is still being worked on.

#106 Re: Science, Technology, and Astronomy » Mars 11 Earth 4 - hostorically Mars is a hard nut to crack » 2003-07-27 09:15:20

No problemo. smile  If there's a gravitational anomaly deviously lying in wait for unsuspecting probes flying to Mars it seems that the type of equipment used to measure variations in the gravitational field around Earth and Moon could detect it.  It's possible the Martian gravity field has already been studied but then again maybe the anomaly is camera shy.   :;):

#107 Re: Not So Free Chat » The death of idealism - A place of mourning. . . . . .or joy? » 2003-07-22 23:16:05

I suppose no ideals would be apt to anarchy. . . .

If you believe that do research into anarcho-syndicalism and anarcho-primitivism.  The idealism of these movements maintains that hierarchical power is always corrupt and exploitative of those at the bottom (among any other things.)  I'm not sure I would go so far though as to say that idealism is always a good thing.  More people have been butchered under the guise of idealism than anything else.  Nazis, after all, were very much into idealism.  And please note, I'm not saying anarchism is right or wrong, only that it does have idealistic roots.

Without idealism, what is the ultimate goal of man?  His own self gratification?  or his neighboors self gratification?

Depends on the brand of ideology you subscribe to.  There are very individualistic political ideologies and very collectivist ones.

#108 Re: Science, Technology, and Astronomy » Metallic Hydrogen - Research Discovers Metallic Hydrogen. . » 2003-07-18 20:53:25

Considering that the Livermore lab is interested in using metallic hydrogen in technology meant to deliberately kill us, I'd say it's a bad thing, but that the spinoffs could be good.  Problem is though, if they did find a way to create metallic hydrogen and it did improve bomb designs would they allow others to use that technology for civilian purposes?  Something tells me they wouldn't. sad

#109 Re: Science, Technology, and Astronomy » Metallic Hydrogen - Research Discovers Metallic Hydrogen. . » 2003-07-18 17:57:19

A possible way to stabilize metallic hydrogen is to create some metallic hydrogen with a extremly heavy duty compressor, then expose it to a extremly large current of electricy and then just expose more electricy and hydrogen to the mix.  (metallic hydrogen is a superconductor)

Peter Hoffman says in his book "Tomorrow's Energy" that it might be possible to keep metallic hydrogen stable by adding small amounts of other materials to it so it becomes an alloy.  According to that same book it takes over a million atmospheres of pressure to create metallic hydrogen.  Apparently metallic hydrogen is also good for nukes since you can pack a lot of hydrogen into a very small space.  That's probably the real reason Lawrence Livermore lab is interested in it.   sad

#110 Re: Not So Free Chat » SETI@HOME->NEWMARS - Discussion - newmars seti@home team » 2003-07-18 17:38:39

I tried the new setiathome client, but it wouldn't show me how much data had been analized and it looks like it's frozen when it's analizing data. I won't know when it's almost done or not. I don't think that I will use it much. Are there any more programs like that but more advanced technically?

You could try http://www.stanford.edu/group/pandegrou … lding@home if your not set on finding alien signals.  Thier program uses distributed computing to simulate the folding of protein molecules that could be put to medical and other uses.

#112 Re: Not So Free Chat » Enviromentalists and Techocrats - The unholy union » 2003-07-15 16:36:21

A lot of environmentalists fear that the advancement of science and technology is going in a direction that's seeks to dominate nature rather than preserve it.  Some examples include genetically altered plants and animals that might escape into the wild that will either outcompete or decimate the ability of their wild cousins to reproduce and military technologies which aren't exactly renown for their environmental record (see this for instance.)  Ultimately a lot of environmentalists believe that technological advancement alienates us further and further from nature.  John Zerzan covers these topics in most of his books.  As soon as I find it I'll post his definition of technology from the "Nihilist's Dictionary."

#113 Re: Mars Rovers / University Rover Challenge » Limited Machine, Unlimited (mostly) Man - Rovers Suck!!!! » 2003-07-15 16:25:53

Rovers have some things going for them though, they are much cheaper and safer to send to Mars.  One of the problems with modern rovers is that they are small and limited energy and instrument wise.  Instead of going through the hoopla of sending people and their instruments, it would be better just to send the instruments in a big, well powered robotic lab that could be better manipulated telerobotically (and I don't mean driving it in real time.)  Anyhow,  humans also break down and only have so much ability to fix equipment that goes haywire.  Ultimately, you can't fix a dead human, especially if they're 53 million miles away.

#114 Re: Human missions » What do you think of returning to the moon? » 2003-07-14 22:53:51

Considering the cost overruns that plague the ISS, and the political idiocy that often dictates its goals, I'm wary of how useful a moonbase would ultimately be.  Will it end up like the ISS, just some half-assed, overpriced pile of cans that fails to do serious science and only keeps a handful of people around to make sure the hinges don't squeak?  I've turned into a real cynic when it comes to government manned space programs.

#115 Re: Science, Technology, and Astronomy » Mars 11 Earth 4 - hostorically Mars is a hard nut to crack » 2003-07-13 21:45:13

Shaun, do you mean the Voyager and the Pioneer spacecraft?  Those are the only two probes that I know of that have managed to ditch the Solar System and encounter those anomalies.  Or maybe Ulysses has been affected by the same forces inside the Solar System?

#116 Re: Intelligent Alien Life » Should Klingon be an official language? » 2003-07-11 03:23:05

Actually he's not kidding.  There are cases where mental patients will speak nothing but Klingon, so the shrinks are searching for people who can translate Klingon into English.  If you google it you can probably find articles about it.

#117 Re: Terraformation » When should we terraform » 2003-07-10 21:33:36

The gremlins must be bored stealing socks out of dryers  because Shaun's July 10 message has also disappeared.

#118 Re: Life support systems » Discover Magazine - July 2003 article » 2003-07-10 21:28:49

What were some of their ideas for recycling the atmosphere?  Did it involve the use of plants or other biological processes?

#119 Re: Science, Technology, and Astronomy » Retire The Shuttle, Designer Says - End spaceflight until we have good ship » 2003-07-10 21:22:39

My vote goes to ending government-funded manned spaceflight altogether even though military interests might have something to say about that.

#120 Re: Interplanetary transportation » Weight reduction to reduce fuel need. - weight reduction over greater ISP » 2003-07-09 20:41:06

It has been proven that steel will be 300-900x stronger when cast in zero gravity.

Can you cite a source on that?  I've read that carbon nanotubes have a theoretical possibility of attaining a tensile strength 200x that of steel, but I've never heard of any materials that could be 900x stronger than steel, at least tensile wise.

#121 Re: Interplanetary transportation » Minimal Propellant SSTO - Using space power to boost from Earth » 2003-07-09 20:32:57

Research at Rennsayler Polytechnical Institute has found that a 1km diameter solar station that could produce up to 20 gigawatts of power.

Another option could be to use giantsolar pumped lasers in orbit that might be able to power the light craft directly even though your method would probably reduce the chance of passengers being fried enroute.

#122 Re: Not So Free Chat » 18th Century:  Age of Enlightenment » 2003-07-09 14:09:43

Of all the philosophers you mention, which would you vote for president if they all rose from the dead and started campaigning?  Which one would you be least inclined to vote for?

#123 Re: Not So Free Chat » Democrats to Mars? » 2003-07-07 10:16:02

Anybody read that MS email about that professor who thinks the next Democratic presidential candidate should push for a manned Mars mission?  I doubt it would impassion the masses to spend their tax money on frivolous flights to Mars when people are hoping to God they can just keep the next paycheck coming in.  Such a campaign issue has the potential to make the Democratic candidate the butt of jokes and appear non-serious in a lot of ways.  It could backfire, especially since half the American public seems convinced now we never even went to the Moon.  Will the Mars trip be a $500 billion dollar stage production?  big_smile

#124 Re: Civilization and Culture » Why anarchy must fail - There will alway be leet » 2003-07-07 09:55:16

99% of human history was spend in a state of relative anarchy.  It was only with the invention of agriculture that massive division of labor made possible the type of political hierarchy and oppression we have today.  Read anthropological studies of the few remaining hunter-gatherer groups that still exist.  They tend to be very egalitarian and non-authoritarian.  It's amazing it took so long for humankind to invent agriculture.  Why is that?  Perhaps, as happened with some Native American tribes, they found it more fulfilling to leave sedentary agriculture behind and return to the foraging way?  Foragers had a superior society in my opinion.  Nowadays we're just regimented, aliennated, and exploited by the power hungery and the ruthless.  I'd love to throwaway the clocks, the technology, the governments, the corporations, and the elitists who think us lowbrows need their every breath and mandate.  But alas, there's too many people to truly return to nature and become feral and wild human beings again.  Civilization is a curse, not a blessing.

#125 Re: Science, Technology, and Astronomy » Russian Race to the Moon - Korolev Biography and what it says » 2003-07-07 01:01:19

I read that book awhile back.  Too bad the USSR's paranoia about the shuttle killed the moonbase plan.   It's ironic how Korolev went from being a slave doing hard labor to becoming the Soviet's top space official.  He easily deserves as much credit as Von Braun for getting the ball rolling in space.
