#1351 Re: Interplanetary transportation » Gravito-magnetic effect - "Breakthrough propulsion" » 2002-12-13 20:08:50

now, saying the ISS is pointless is a big stretch.  as for the defense industry, it did give a lot of work to an otherwise dead sector of the economy, which is never a bad thing.  and are you going to tell me NASA designed this hunk of metal so astronauts could have coffee and play games on it all day?

#1352 Re: Interplanetary transportation » Gravito-magnetic effect - "Breakthrough propulsion" » 2002-12-13 18:24:35

the problem with the nasa budget over the past 5 years was that we actually expected the ISS to be an international project.

we were even so unreasonable as to expect other countries, *cough Russia cough* to fulfill their portion of the production.  unfortunately, that didnt happen, and we took over, much, to say the least, of their comittments.  thats the biggest reason for the overruns.

wouldnt bush know this beforehand?  this seems to be the result of some silly errors in planning.

#1354 Re: Not So Free Chat » President Bush - about bush » 2002-12-13 17:07:45

or einstein, much closer to our time.  he would be crushed.

#1355 Re: Not So Free Chat » President Bush - about bush » 2002-12-13 16:24:33

I wouldnt say the greatest, but it has had beneficial effects, yes.

#1356 Re: Not So Free Chat » President Bush - about bush » 2002-12-13 16:10:16

you just contradicted yourself within the same post.  you said we should disarm them, yet we cant because china is next door.

who are we to say?  when are we going to disarm some of our thousands of warheads?  when is russia going to do so?  the way our president is handling the situation of nuclear weapons is terrible-refusing to disarm a single american weapon, arbitrarily selecting nations that "threaten" us, and ignoring others.

#1357 Re: Interplanetary transportation » Project Orion Revisited. - Why not an Earth Launch? » 2002-12-13 07:57:36

i dont fear everything nuclear, thats totally off base.  but blowing up hydrogen bombs in earths atmosphere is another story.  nuclear energy is the future of space exploration--but not every nuclear energy source is as risky as nuclear weapons.

i support nuclear power.  but there are two sides to everything.  you should know that shaun.  just because one person has provided numbers to prove a point, doesnt mean somebody else couldnt provide numbers that show that the opposite is true.

#1358 Re: Interplanetary transportation » Project Orion Revisited. - Why not an Earth Launch? » 2002-12-12 22:03:42

well, let me ask this:  is there any method of propulsion available in the near future that could provide the same benefits as nuclear pulse propulsion, but with less safety risk (at least, less psychological risk...to be honest, im still not sold on blowing up hydrogen bombs in the atmosphere ??? )?

#1359 Re: Intelligent Alien Life » More and more, Mars looking like no life » 2002-12-12 21:56:28

yes, that is the major one, that ive heard of.  how else do you explain the sudden onset of life? 

it was also mentioned on cosmos, and in zubrins books.  i guess zubrin doesnt know his space science.

#1360 Re: Martian Politics and Economy » Space development and Earth's Environment - BAD BAD BAD! » 2002-12-12 21:54:47

if you live anywhere but africa, its kind of ironic.  yes, im sure you would have been the one to say, no, lets not go north, we don't want to kill any more animals for food.  its not fair.  and the strongest, most clever people shouldnt be allowed to succeed, because us lazy, whining people dont have the drive or wherewithal to compete.  boo-hoo.

never mow your lawn again.  thats terraforming, buddy.

#1361 Re: Interplanetary transportation » Project Orion Revisited. - Why not an Earth Launch? » 2002-12-12 21:50:26

i still dont like the idea of exploding nuclear bombs in earth atmosphere.  is there any way to get the ship into space before using the bombs?

maybe the pulses could be combined with another type of nuclear power, where the pulses could be used to provide short periods of high acceleration.  but you seem to be the expert on the issue, nuclearspace.  could this work?

#1362 Re: Planetary transportation » Crawlers - Segmented multilegged rovers » 2002-12-12 20:39:01

. Being squat, they wouldn't fall over. Or topple into gullies or from cliffs (say) if programmed to hesitate with their trailing feet gripping surfaces already traversed by their leading feet...until images of what was ahead had been transmitted (via whatever) to Earth for evaluation.

its funny, i had a lego robot set that could do just that.  well, almost.  it had a photocell that made the robot stop when it came to a black line.  simple progamming, for kids.  well, my guess is that we could make a device extend, say, a yard in front of its legs, attached to the body, that sent sonar beems to the ground.  when it came to a point where the ground dropped significantly, it would stop.

#1363 Re: Interplanetary transportation » Power Limits of Advanced Propulsion » 2002-12-12 19:20:45

this seems great for cargo deliveries (hell, it might even make orbital hangars practical), but my interest in SSTO's is as a fast airplane.  the market would be HUGE.  it could be extremely versatile, delivering people and goods to space and earth on the same, short trip.

is there any work being done over there on that type of vehicle?

and i plan on checkin it out, kinda busy atm.

#1365 Re: Interplanetary transportation » Power Limits of Advanced Propulsion » 2002-12-12 17:15:08

mauk, any way to make that horizontally taking off, like an airplane?  it would allow us to use already existing facilities, and more often.

#1366 Re: Interplanetary transportation » LH2 fuel replacement... - ...NaH / NaBH4? » 2002-12-12 17:12:53

i dont think something that toxic will be looked upon with any more favor than nuclear systems.  in fact, i think that they will make nuclear systems more favorable, which may or may not be a good thing, depending on your perspective.

#1367 Re: Not So Free Chat » President Bush - about bush » 2002-12-12 17:08:26

bah.  i dont want a convicted war criminal in charge of rebuilding Manhattan.

#1368 Re: Other space advocacy organizations » Colonizing asteroids » 2002-12-12 17:07:30

actually, approximately 1/2 g is not that drastic.  people who have lived a long time in zero G (which never has to be the case in mars direct) had no problem getting back home, and living normal lives. 

in my opinion, to build an interplanetary colony would be wasting time and resources that we would better be exploiting by living on the planets the resources come from.  if we were to use asteroid material, its a different story, as i dont see asteroids as being a huge destination for colonization.  but a new colony between planets isnt going to solve overpopulation either. 

theres no reason people have to be sent in "sardine cans" forever.  as technology develops, we will be able to have larger, more comfortable transport ships.  you think the british army came to america in the same conditions as the pilgrims?  no.  as an impetus for development of new ideas and technologies arises, bigger and better things are developed.  just look at computers.  in just twenty years, we've gone from bulky machines about the power of calculators, to the PCs of today.

#1371 Re: Interplanetary transportation » Light-sail propulsion - Solar photon-driven sailing alternatives » 2002-12-12 16:40:15

when phobos mentioned lasers, what i was getting at was that you could put multiple "laser stations" in the outer system to propel missions.  isnt voyager still powered by nuclear reactors?  we could use those to power lasers, no?

#1372 Re: Intelligent Alien Life » More and more, Mars looking like no life » 2002-12-12 16:25:19

earthlings might not be earthlings.  the major theory ive heard about life's origin on earth stems from a comet (or comets) that brought the organic matter needed for life to earth.

#1373 Re: Not So Free Chat » President Bush - about bush » 2002-12-12 16:23:34

i would rather see mccain run again.  he was the best candidate, imho.

#1374 Re: Interplanetary transportation » Project Orion Revisited. - Why not an Earth Launch? » 2002-12-12 14:11:32

we have enough information on all variables that computer simulations can tell us enough to sway the issue one way or another.

#1375 Re: Not So Free Chat » President Bush - about bush » 2002-12-12 14:06:53

and i will treat you as you are, somebody with a big mouth who doesnt have any experience, and likes to argue for the sake of arguing.
