But maybe that's the point: make it go away ASAP, by fleshing out articles.

Exactly wink

Great job you're doing, BTW!

Thank you. Everyone is doing a good job!

1) I think NewMars is international. The fact that's in English and most members are from US doesn't mean it's American. Adrian Hon himself is from UK, if I remember correctly, and there are Mars Society Chapters in many other countries.
Of course, you can't force someone that doesn't know the metric system to use it. But, someone can edit after and also put metrics. The way i did it in http://www.newmars.com/wiki/index.php/Mars (the paragraph with temperatures).

2) I was asking for things like: Martian climate vs. Marsian climate. And yes, I got the inspiration from RobS. What do you think ?

3) Well, see the Mars article above. It has information about water on Mars, but there are only common things, not by far enough, so a full article was created, "Water on Mars" (not by me - and it needs to be expanded, BTW). I think it's wise to put inside (for example) the "Mars" article link to "Water on Mars", in the proper context, the way i did. Thus, when someone would like to read more about water on Mars, after reading the Mars article, can easily click there. And yes, I think this adressed exactly the "lot of different things, that could merit their own page" problem.

4) Ok.
Josh ? (Can he hear us ?)

5) Indeed, doing things in that way has no point. But most articles on WikiPedia are too general (and Mars related ones are no exception). There are delicate things you won't see on WikiPedia ever, because it's more of a general encyclopedia. Usually articles there don't get too much into the subject. We might expand those articles even an order of magnitude.

I mean, seriously, in the future there might be enough information on NewMars Wiki to transform it into some kind of Colonist's Manual for Mars. At least, I hope so. It would be great to have everything about Mars on the wiki.

6) New issue: How about other planets ? The Moon ? etc. Is there enough bandwidth and disk space for something like that ?

A few issues I think it's better to discuss here (initially posted on the Main Page Talk)

1. I think that all units in all articles should be in the metric system, with English ones put in paranthesis... It's okay ?

2.  Martian or Marsian ? Well, which one to use ? Martian sound too much like martians (the little green things coming to invade Earth - blah)

3. "Main articles." When we need to write a very general article (Mars for example), for each thing discussed there we should put a Main Article link. (See http://www.newmars.com/wiki/index.php/Mars for example).
I think i'll create a template for this.

4. Update to Wiki ? I think it's a good idea to update the wiki software to version 1.5.6. It has more features (<noinclude> tags for example, which could be quite useful).

5. Also, it's okay if at the begining we literally take some articles from WikiPedia ? I know, it's not supposed to be a rip-off. They are too general anyway and must be expanded later. But we could start from there. Also, WikiPedia is GNU Free Doc License, and allows to take entire articles.

No problem, Rxke.
About stub positioning: i think the stub template {{stub}} should be put at the very beginning of the page. I initially put them to the bottom, but it doesn't sit well there especially after i put them in a frame with border. And also, it should be visible as soon as someone opens an article.
What dou you think ?

#81 Re: Life support systems » Aerogel - don't build - your greenhouse w/o it » 2005-05-11 00:27:38

I think aerogel cracks very easy under some small mechanical pressure (like some wind hitting the greenhouse for a few weeks?)... I least this is what I remember...  sad

#82 Re: Life support systems » Robotic Tomato Harvester » 2005-02-16 03:07:09

IMHO a robotic tomato harvester on a manned mission is quite unnecessary.
But, a robotic "gardener" could be quite useful for certain mission designs, which propose to send a lot of equipment and a greenhouse some time (like 1 year) before the crew itself. The fruits would be conserved, obviously.
But the question arising here is if such a robotic gardener would be dependable enough, so the crew wouldn't have some very very bad surprises when they arrive on Mars.

#83 Re: Life support systems » Getting air on Mars » 2005-02-16 02:41:14

Is yttrium (dunno if that's the right way to write the element in English...) available on Mars? I's a rare-earth metal, no?

Yes, yttria is the oxide of yttrium (Y2O3), which is a rare-earth metal.  smile
If it's available on Earth, you can bet it's available on Mars too. Actually, I think almost any minerals we have here on Earth can be found on Mars too, but in slightly different proportions, with some exceptions, like hematite smile . At least that is what I hope. If it's easily obtainable (are there deposits? are the deposits close to the surface?), that's another set of question, to which future colonists 100-500 years from now will have to answer.

http://pearl1.lanl.gov/periodic/element … ts/39.html :

Yttrium occurs in nearly all of the rare-earth minerals. Analysis of lunar rock samples obtained during the Apollo missions show a relatively high yttrium content.

http://www.webelements.com/webelements/ … Y/key.html :

Pure yttrium is available through the reduction of YF3 with calcium metal.
2YF3 + 3Ca -> 2Y + 3CaF2

But apparently solide oxide electrolysis doesn't produce enough oxygen all by itself, and IMHO it's not a good idea to be dependant of only one source, so there is the need for another sources, like plant photosynthesis and H2O electrolysis.

#84 Re: Life support systems » Getting air on Mars » 2005-02-15 13:22:32

There is a unit, the name escapes me at the moment, that takes in martian carbon dioxide, heats it, and passes it over a ceramic grid.  This separates the oxygen from the carbon monoxide, the carbon monoxide is then discharged.  The machine is small, about the size of a volleyball, and it produces very small amounts of oxygen.  I think I figured out a while back that it would take over 100 of them to provide enough oxygen for two people a day.

Solide oxide electrolysis, using yttria-stabilized zirconia. For example, read this:
