#26 Re: Human missions » Design wanted for Antarctic base - Mars colony? Anyone? » 2004-06-29 23:00:39

Particularily in the cold weather, which I suppose is sort of obvious.

Too bad that Antartica doesn't have the low pressure that Mars has (for feasability tests).

They have done a greenhouse already http://www.antarctichydroponics.com]here.
That is pretty impressive. I would love to see them expand that, particularily with lots of our help.

Holy Crap!

M. A(ntartic). R. S.? We should definitely try to get our fingers into this. Maybe it could be a test-venue for new techniques of construction/habitation suitable for Mars.

#28 Re: Not So Free Chat » Disney's Mission: Space - Edutainment? » 2004-06-28 19:09:23

So Disney has a http://disney.go.com/vacations/missions … h.html]new ride that supposedly is an experience where you are taken on a voyage to Mars, as well as a "simulated" lift-off. I saw a special on it on the Discovery Channel, and I was wondering how accurate/realistic it actually was. Does anyone know anyone who has gone on it and can give thier own opinion?

It sounds like they have gone through a lot of effort to either make it realistic or fun - I can't tell much more from the website. Apparently on your "team" of four you are assigned different roles. Pretty spiffy and attractive to me at least.

I seriously doubt intelligent life originating from Earth, specifically us, will ever end. I am just saying that in 100,00 years it will barely resemble us. It's too bad we couldn't split up those option. Let's take laser-eye surgery, hearing aids and even cosmetic surgery. That is just what we are clumsily doing now. In at most a 100 years gene therapy will be prevalent everywhere. In a bit more it might even be MANDATORY to have your children's genes altered at birth so they can catch up with everyone else/not develop an expensive terminal disease. I mean it is IRRESPONSIBLE once we have significant genetic knowledge to have children that will definitively develop Hungtington's disease or progeria or Alzheimer's. Once those diseases are eliminated (in only a thousand years at ABSOLUTE MOST) where can we go from there? I could see significant genetic redesigning. And if we go on to other planets, who says that our colonists won't be genetically developed to survive or adapt to the planet?

It makes me excited.

So the human species will definitely not exist as it does today in 100,000 years.

I know about Mars Direct but for some reason NASA seems to ignore it. Maybe someone knows why?

Ha ha ha.

There seems to be a multitude of ideas (the majority of which are good and will work) but it seems that all we need is somebody who happens to be in power to go "Yeah, I like that." and devote money to it. We can wait for someone like that with real will until it happens (dumb luck), we can lobby (which the Mars Society does alot of) or we can get a angel investor to make something actually happen (SpaceShipOne).

I must admit SpaceShipOne is a BEAUTIFUL design. I mean just look at it - and it is shirt sleeves. Government agencies get more solid STUFF done but when companies actually do something it is amazing. Another good example would be all the VTOL. I get so excited whenever I see videos of those.

So what do we need? will. to do something. I'll see what I can do here.

#31 Re: Human missions » Sooner the Safer - Only the Paranoid Survive » 2004-06-26 14:45:24

Well he's right. The more locales humanity has the more likely we are to survive any major disaster/conflict.

The thing that people seem to miss out on is that colonization will make the solar system a whole helluva lot more INTERESTING. All the openings of culture and such that will occur because of us spread like primodial goo from planet to planet. Of course there is no clear return on this in sheer $$$. Too bad.

*In a couple of months?  ???  According to the news I heard last night, they've got 14 days.

Can't recall the specifics of the X-Prize (I'm information overloaded as it is).

--Cindy

You also need to send up 3 people on the flight, and they only used one (Melville) this time. I'm not exactly sure if it is the "weight" of 3 people or 3 actual people. The former seems like cheating to me.

I thought Evil Genius had a dimensional port into which he can escape into one a timeless dimension and rebuild his army there.

But perhaps I'm getting out of touch.

We better get to Mars quickly before these foolish notions of grandeur get out of control.

Oh my, if congress read this. tongue

#34 Re: Human missions » The Case Against Mars - Why Mars is not a good target! » 2004-06-17 14:29:29

It appears to be so yes. In the article that John posted earlier, http://www.cns-snc.ca/Bulletin/A_Miller … .pdf]Heavy Water: A manufacturer's guide for the hydrogen century, it says that Venus contains a whopping 2.2% deuterium in it's water, whereas earth only has 0.0155%. The article says there is much less water, however, on Venus (which is why there is more deuterium) so it may be in fact harder to get to.

For clarity, Mars has 0.1% deuterium in its water.

#35 Re: Life support systems » Pizza's!! - How are you going to deal with it? » 2004-06-16 14:02:21

"untested systems"...how about:

It seems that there needs to be a lot of infrastructure in the way of food neccesary to even allow humans to inhabit Mars comfortably. What about sending in advance all the pieces to start a decent farm. Starting with simpler plants, and then working out the bugs and moving on to more complex plants as the technique becomes more refined. (seeds for the difficult to manage plants can be stored in some way until neccesary) This could be an ongoing base on Mars to test the feasibility of different technologies with NO RISK TO HUMANS, while benifiting the potential for human exploration significantly.

Of course it could be run by robots, and would generate more press than the even the current ones which, let's be honest here, take pictures of rocks.

After at least a decade of the project (and possibly more landing and rendezvous on the surface) then it is possible that there will be a sufficiently large and varied infrastructure to support and satisfy the "picky human pallete".

The beauty of this is that it could start at the level of simplicity and scale of the current Mars Rovers - possibly only 4-10 m^2 at the start. And since nothing is consuming the food, all dead matter will be directly re-composted and put back in.

VISUAL: In the foreground, a 15 cm tall vividly green pea plant stands in a small plastic bubble, in stark contrast to the arid red landscape that surrounds it.

It's really sad that we need to go to all sorts of lengths to ensure that astronauts have...I geuss I'll say it..."Happy Meals". Is it possible to just bring along some high-power, high-concentration flavour powder that makes it just taste like the real thing? All you have to do is close your eyes.

#37 Re: Life support systems » Most Important Animal to Mars - What animal will be most useful? » 2004-06-04 10:20:30

At a guess, but a decently informed one, I would go with potatos.

Until we get a potato famine

We need peanuts plants too, because I personally like them and they are high in protein. Speaking of high in protein, what about eating the worms after they die - I hear they are high in protein

#38 Re: Planetary transportation » Navigating on Mars » 2004-06-04 10:16:13

Hmm, thought about it and one problem is that the signal would not travel in a straight line toward the rover but bounce back and forth from the atmosphere and ground thus traveling much farther and giving the wrong distance.

I think the direction finder part would work well though.

Maybe a system that combines information received from a heading gyro and something that measures the amount of wheel rotation?  It could all be combined by a computer program to determine position.

You could use an ADF (automatic direction finder) system just like Earth-based aircraft use. It is an old system but it does have the advantage of working over-the-horizion. However, as far as I know, all it provides is a bearing to the station and does not provide a distance measurement.

http://www.allstar.fiu.edu/aero/ADF.htm … ro/ADF.htm

In the link, as I thought, it says the ADF reflects the radio waves off earth's ionosphere. Now I'm not sure, but I don't think that Mars has the same thing, so this may not work, at least not on the same frequency.

Anyone?

On the GPS issue: Why not every satellite we send up to Mars in the future be equipped with basic technology. At first, the APS (ahem) can actually acknowledge it's "customers" on the ground because there will not be an excessive amount of traffic of "users" using the system. So the satellites can communicate with whoever is on the ground, reducing the number of satellites needed, I think. They don't fill the same role as the GPS beacons, which are just simple beacons.

And another possibility: why not a series of ground-based beacons/weather stations which might have been constructed anyway? Assuming a antenna height of 2 m, the distance to the horizon is 3.7 km If you use a 3 m antenna, the distance increases to 4.5 km. If there's no problem with stretching yourself really thin, the distance can even be 8km between beacons (so you can see both but they can't see eachother). This is also assuming you don't take advantages of natural topography.

So basically what you are proposing is say, Mars Direct, with wheels and a strong rover that can pull it? I like it in principle.

One problem I see is that the Hab may require a lot of beefing up, with shocks and sheer structure, particularily if the terrain is rocky.

Otherwise, why don't we just land a HUGE rover that also happens to be a hab instead of a rover/hab combo? More simplicity, oui? Unless you want to have autonomy for exploration while people stay in the Hab. Well now I am just thinking out loud.

So, major obstacle: weight
