3.   Aging deceleration: Extension of mammal life, or demonstrated evidence of aging reversal

I can't wait ot see what comes from this one.

I can easily see that you are against desatroying a primitive species on another planet. Why? I just don't why that life would mean so much to you.

#4 Re: Human missions » Using Europa To Terraform Mars - wacky science or real possibility? » 2004-09-27 18:59:45

I always thought that nature lived by the law of survival of the fittest. Species used to die out under stronger species all the time but now when humans get close to doing this they are fought against by enviromentalists. I don't get it. Humans are the fittest and we have the right to do whatever we please as long as it doesn't kill ourselves. I also think that spreading to other worlds is the exact opposite of killing ourselves off because it gives the human race much more chance of surviving a catastrophe.

If there is life on Mars or Europa is it primitive and dying off. Neither of these worlds will ever give rise to intelligence. As the only intelligent species in the solar system we have the right and I dare say the duty to use these worlds as we see fit.

I agree.

Would it be good to build a colony at the bottom of Valles Marineris?

#6 Re: Human missions » Location » 2004-09-21 22:04:18

Im not sure if this has been discussed hear already but where should the first colony be. I think that it should be near the polar ice cap so there would be a water supply. I don't see how else to get water because we haven't identified any  underground aquifiers yet.

Where does everyone else think would be a good place?

I don't see how air could leak out of a solid rock cliff. Would this happen though?

What about this. This could produce enough energy for a local magnosphere.

Another colony design I Liked is roofing a canyon. Since you already have walls and floor the roof is all you need. I think this was from KSR as well. Could this one work?

#9 Re: Human missions » China The Dominant Superpower In 20 Years..... - What does this mean for US? » 2004-09-19 21:37:02

The three gorges dam is made of concrete that is more than 100 meters thick.  It is designed to withstand an earthquake measuring 10 on the Richter scale.  It would be very difficult to destroy it without using nukes.

Just because it was built to withstand that doesn't mean that it could. Cracks were being found in the early stages of development and after they were repaired they reapeared larger. Also the dam is built directly under an active fault line.

Has anyone considered a union with china and other space agencies?

#10 Re: Exploration to Settlement Creation » Constructing a larger settlement - One idea » 2004-09-19 19:44:58

What about KSR idea of melting out a dome in an ice cap. This would not only provide sufficent radiation shielding  but also water and oxygen. I was wondering though if working inside the dome would cause it to melt larger until it reached the outside. I guess the atmosphere inside could be kept at a cold temperature.

Does anyone like this idea?

#11 Re: Human missions » China The Dominant Superpower In 20 Years..... - What does this mean for US? » 2004-09-19 18:41:47

I would think that china may destroy itself in one way or another. The three gorges dam on the yangtze river will soon become a stangnant pond after its completion. Most of the nearby cities dump all of their waste in the river. Once there is a large enough buildup a terrorist attack would easily be able to destroy the dam killing millions with flooding and the millions more with the epedemic the waste water could cause.

Besides taking china out has anyone thought of merely joining with them. I realize that a competion could spur a quick development of many new technologies but it is also true that two heads are better than one. The world is against each other in many different ways. including politics, economics, and even terrorism. Why should we be against eachother on space. I personally think that the worlds space organizations working together toward a common goal would be much better than it is now.

#12 Re: Youth Group / Educational Outreach » Degrees/subjects for future Martian colonists - What will I need to know? » 2004-09-19 18:11:11

I am interested in both chemical engineering and architecture. I know that both of these have pratical uses on Mars but I am still undecided at which I should follow.

#13 Re: Terraformation » Animals on a terraformed Mars - what should we populate Mars with? » 2004-04-24 09:02:37

About withstanding the ride-They could be eggs and sperm

Feed-If Mars is terraformed enough for animals then there should be plants

Waste-Fertilizer big_smile

#14 Re: Terraformation » Methods of terraforming - How to go from bone dry & lifeless » 2004-04-23 16:02:14

I think that a few mohole should be built where the lithosphere is the thinnest so that volcanoes could be made. Also where oceans are going to be because ice should collect before there is a lot of liquid water and the moholes could help heat it from underneath. Also I don't think that they would be that hard. It could all be automated.

#15 Re: Terraformation » Speed Bumps to Terraforming (Anywhere) » 2004-04-23 15:55:11

Even if there aren't vast amounts of water on Mars i shouldn't slow terraforming down too much. We would probably have to pump some of the underground resevoirs to the surface but if there aren't any to pump then you can use that time and money to get astroids. Besides areobraking ice astroids into the atmosphere with add more water vapor to the air than pumping liquid water to the surface would. This water vapor would increase the temp more and release more water from the poles.

Don't the poles go underground also? Like an iceberg where you can only see a small percentage of it. This is what I heard somewhere, don't know if it is true.

#16 Re: Terraformation » Methods of terraforming - How to go from bone dry & lifeless » 2004-04-22 21:03:25

You could also:

Cover the poles with regolith
pump aquifiers to the surface

Or like in KSR Mars triogy we could have a soletta to increase the suns intensity all over the planet and then use a mirror to direct the light int small areas melting the regolith and putting volatiles into the air.

Could this actually be done?

#17 Re: Terraformation » Terraforming Mercury - Is anyone this crazy? » 2004-04-20 20:46:22

Before colonization of Mars we could crash Mercury into it and add a little mass and then use the ejecta to for a moon in proportion to Mars as luna is to terra. It could happen couldn't it?

#18 Re: Terraformation » Terraforming the Earth’s great Deserts - Turning the Sahara into a rainforest. » 2004-04-20 17:15:12

Although canaling water into the Sahara sounds like a good idea I don't think it would be too smart to experiment with orbitting mirrors and to many others things on are home planet. All the more reason to terraform other planets though. To gain experience so that when it is needed Mother Earth could be saved.

#19 Re: Terraformation » Terraforming Venus - methods anyone? » 2004-04-20 17:11:53

Is it possible to bomb some of the atmosphere off? Like dropping large boms into the upper atmosphere where they would explode and expel clouds and gases into space. Could this work?

#20 Re: Terraformation » Speed Bumps to Terraforming (Anywhere) » 2004-04-20 17:08:31

Thats a good comparison. I like that one. I am about 100 pages into Blue Mars right now and through out all the books it really seems that KSR is a green. I know that I am a green. Not only for Mars though. If it was up to me I'd have so many missions to Venus, Mars, The moons of Jupiter, and Titan. But I guess that is only if it was up to me sad

#21 Re: Terraformation » should we or shouldn't we? - Are you for or against Terraforming? » 2004-04-20 17:04:17

Thanks kippy. Your link was much better. Maybe I should try that one on different sites.

#22 Re: Terraformation » Rapid Terraforming... - ...the most ambitious ideas? » 2004-04-20 16:16:20

What type of inscets don't need oxygen? Are there any? If so these could be introduced first. We could fill the martian soil with worms in preparation for plant life.

#23 Re: Terraformation » Rapid Terraforming... - ...the most ambitious ideas? » 2004-04-19 17:31:38

My science teacher once told us that 85% of Earth's oxygen comes from phytoplankton. I'm not sure if this is ture but if it is then wouldn't it be fairly easy to scrub CO2 from the Martian air once the planets is warmed up? I mean you rais ethe temps with greenhouse gases in order to get oceans. Then fill the oceans with algae and plankton. A whole lot of them. Then when there is enogh oxygen add some whales to take care of the plankton and start the ocean biosphere.

Could this idea work?

#24 Re: Terraformation » should we or shouldn't we? - Are you for or against Terraforming? » 2004-04-19 16:55:51

I'm trying this poll on several different Mars sites to see what the percentages are.
