==Overview==
"Building upon concepts and designs from the past several decades, the [[Mars Homestead Project]]™, the main project of the '''Mars Foundation'''™, seeks to develop a unified plan for building the [[hill-side concept|first habitat]] on Mars by exploiting local materials. The ultimate goal of the project is to build a growing, permanent settlement beyond the Earth, thus allowing civilization to spread beyond the limits of our small planet."

=Main Page development=
I have made an attempt to upgrade the front page to improve design, ease of use and accessability to the wiki. I have tried to focus on accessibility for new users as we need to increase online interest in our efforts.

Some recent updates:
*Inclusion of a "[[Featured articles]]" on the front page (see [[user:Ioneill]] for development details).
*Creating [[Marspedia:About]] page to move bulk text from main page.
*Creating "Marspedia News" section on front page - for development purposes (i.e. new site developments/announcements), '''not''' to advertise new content.

Unresolved areas:
*Copyright notice, should it be moved to a less-prominent position?

For now, over to you! -- [[User:Ioneill|Ioneill]] 04:19, 23 November 2007 (UTC)

:I like the new appearance. It is better than ever! -- [[User:Rfc|Rfc]] 07:43, 23 November 2007 (UTC)

::It looks wonderful; I can't wait to steal it for Lunarpedia. 8) The copyright rules notice is too large and unwieldy, and as you may have noticed, in over a year I've not figured out a more compact solution that imparts the required information. Maybe a terse summary with a link to a more detailed version? How much can we pare down the summary if so? --[[User:Strangelv|Strangelv]] 08:30, 23 November 2007 (UTC)

:::Hi James, I have seen several occurrences of "8)" in your talk. What does it mean? -- [[User:Rfc|Rfc]] 09:10, 23 November 2007 (UTC)

::::It's an emoticon, akin to ''':-)'''. I wear glasses, thus the eight instead of the colon... --[[User:Strangelv|Strangelv]] 11:28, 23 November 2007 (UTC)

:Cool, glad to get people's opinion on it. Kinda melded the Wikipedia format with our own - hopefully we'll be a unique set of wikis in time. I've been looking at the copyright notice, and I think we can work with what we have for now. We must keep in mind, we are in the development phase of this project, so there are going to be a lot of rough edges. As we will (hopefully) have a continuous, and increasing influx of articles, newcomers will need to read the GFDL terms and conditions first. Also, having the copyright notice there is in keeping with Lunarpedia etc., so it's a good visual aid to see we are all in the same "club"!
:James, feel free to copy any of the design aspects and stick them into Lunarpedia, will be nice to see a cool blue and grey version 8) I think the divs and tables are up to par. Seems to be formatted correctly in Firefox and IE, so there shouldn't be too many issues with other operating systems. I've noticed a slight loss in border on the right side of the copyright notice when using FF, will get that fixed.

== Wikipedia based articles ==
I personally support the public domain license, but isin't it alot easier to just fork all the required articles from Wikipedia, then edit them from there? Many articles should be almost complete copies from Wikipedia. Having a "GFDL" namespace seems confusing. [[User:Nawi|Nawi]] 11:36, 1 July 2008 (UTC)
:I don't think there are many articles that should be almost complete copies from Wikipedia. Every Marspedia article is written in the context of building a settlement on Mars, with special orientation to the Martian circumstances. When I started to work for Marspedia I had a similar idea - and an enlightening [[User_talk:Ioneill#Contents from Wikipedia?|discussion with Ioneill]]. -- [[User:Rfc|Rfc]] 20:19, 2 July 2008 (UTC)
::How about "keystone" articles like the Mars Direct article, which Marspedia really should have ASAP? It certainly wouldn't need editing to make it more Mars-y! --[[User:Pete9804|Pete9804]] 19:15, 1 October 2013 (UTC)
I suggest no copy-paste from Wikipedia. Simply type in your thoughts as new work and put a Wikipedia link as an external link. [[User:Miros1|Miros1]] 20:25, 30 September 2012 (UTC)

== Captcha ==
Can the captcha be disabled for registered users or something, because it's pretty annoying. [[User:Nawi|Nawi]] 15:12, 29 June 2008 (UTC)
:Hi Nawi, I agree with you. Since I am an ordinary user I can not change this, but I can give you some explanation about the working principle of the captcha. The ''"gibberish captcha"'' is designed to pop up if the first word of an article is going to be changed (Please see also [[Marspedia:Captcha]]). Also, a captcha pops up for edits that add URLs and for Userlogin. We implemented the ''"gibberish captcha"'' when we experienced frequent attacks by a bot inserting gibberish into Marspedia articles. This captcha works fine, but is certainly a bit annoying when creating new articles. Most edits, however, should not trigger this captcha, since most edits leave the article's first word as is. If you experience a different behaviour, please let me know. -- [[User:Rfc|Rfc]] 07:43, 30 June 2008 (UTC)

Please disable the captcha. It is '''''EXTREMELY''''' annoying. [[User:T.Neo|T.Neo]] 13:25, 3 July 2008 (UTC)
:Possibly [[user:Strangelv|Strangelv]] can disable it for registered users, but I have no idea how to do it. Perhaps it is not possible for the captchas to distinguish registered users from IPs. After all we have to find a good balance of usability and security. If we had no captchas at all, we would get flooded with a torrent of automated spam (as we experienced before the activation of the captchas). -- [[User:Rfc|Rfc]] 18:59, 4 July 2008 (UTC)

== Fountdation of an autonomous colony ==

Is the current FA going to stay on the Main Page forever? I swear is hasn't changed in the last 5 days. [[User:T.Neo|T.Neo]] 12:44, 23 June 2008 (UTC)
:The process of nomination and featuring is not maintained on a daily basis, because nobody is willing to spend the effort so far. For a history please see [[Featured articles]]. -- [[User:Rfc|Rfc]] 12:56, 24 June 2008 (UTC)

O.K. [[User:T.Neo|T.Neo]] 09:09, 27 June 2008 (UTC)

::If possible, could someone write a step by step guide to featuring an article? I mean the coding procedure. I have FTP access if such access is necessary to change the article. I also need to do so on Lunarpedia, but haven't had time to dig through the code to figure out a way to wing it without screwing things up. I doubt that future users will want to go through all of that. -- [[User:Jarogers2001|Jarogers2001]] 07:01, 28 June 2008 (UTC)

:::Nevermind, I figured it out. You guys put your heads together and decide which article you think should be featured and then clear it with Ian. I have this talk paged watched, so I'll know if you post your final decision here. I'll do the grunt work if Ian finds himself otherwise occupied. -- [[User:Jarogers2001|Jarogers2001]] 08:43, 29 June 2008 (UTC)

==Featured Article==
I would like to nominate [[Water]] as the next featured article, although it might be useful to quickly go over it and the most recent results from the lander to make sure it's up to date... -- [[User:Strangelv|Strangelv]] 10:51, 2 November 2008 (UTC)
:Good idea. The ''Interplanetary Internet'' may be replaced by an other article. How about something contemporary? Proposal: [[Mars One]] or [[Curiosity]]? We could also change the ''Featured article'' to ''Currently in the news'' or ''Hot spot'' or ''Most interesting'' or ''In focus'', which does not necessarily refer to the high quality of the article. It might help to attract readers (and authors) who are interested in contemporary stuff. -- [[User:Rfc|Rfc]] 19:27, 22 November 2012 (UTC)

'''''Dear Colleagues,'''''

Your activity is close to us on spirit, we are glad to your successes.

We invite you to discuss the new practical idea of association in the unique program of which the mankind didn't know analogues. The given program has the working name «Otherwise continent» (in Russian - ''[http://ppark.livejournal.com/3678.html «Иной континент»]''). Idea being: to begin in different places of the Earth creation of [http://www.marspedia.org/index.php?title=Independence_from_Earth real planetary settlements], pertinent for conditions of the Moon, Mars, etc. and to offer in this independent settlements habitation and work for high-grade intelligent families.

It will allow to provide advancing development of new land culture and an infrastructure of interplanetary programs which shortly all the same become habitual for earth dwellers. I.e. we begin preventive preparation to grow roots on the planets through inclusion of such independent planetary settlements in a land economic turn, developing thus empty earths, applying renewed energy sources, progressive agrotechnologies, «new pedagogics» and many other innovations which still remain a rarity on the Earth.

Number of inhabitants can exceed and 3 thousand persons in each settlement

There doesn't exist any basic obstacles from the point of view of engineering-technological reserves for this way, both materials Marspedia, and our long-term researches testify it. But the basic alarm is caused by absence in plans and preparations of disembarkation to the planets qualitatively important for settling of planets of strategy – ''strategy of socio-culture dynamics''. This aspect is in especially powerfully developing by our scientists and designers. Mission of the given so-called '''''[http://ppark.livejournal.com/4837.html planetonautics (C)]''' ''strategy also consists in advancing development already on the Earth and at direct participation of all earth dwellers of culture of planetary dwelling …

I.e. for planetonautics priorities vary into how socio-culture drive technology’s development: socio-culture factors become a source of technological development, rather the reverse, as before, in astronautics, for example.

The program is supported by some companies and the research centers of Russia, now we search for partners in a consortium abroad. Their interest is clear: after all in the conditions of crisis such strategy will allow to open new applications for pertinent workings out from any of areas – the industries, astronautics, IT, social technologies, the pedagogic, robotics, transport, the different high technologies, many branches of fundamental and applied science etc., i.e. will suffice affairs on all. There will be new workplaces, families will not break up, new knowledge and technologies, social communications etc. All these workings out be required and inhabitants of independent settlements will be engaged, and superfluous products (energy, a foodstuff, new knowledge, techniques, etc.) will be on sale on a foreign market.

The business plan is developed for the basic land version of independent settlement of type «Solar farm», for three settlements drawings prepare, there is discussion at conferences and on the Internet, students etc. work over themes

We consider that the most suitable time has now come to pour in this strategy the large finance and to provide to it steady progress.

Details it suggested to discuss after your acknowledgment of basic interest.

Yours faithfully,

Nazym F. Sayfullin,

Where does this value come from? -- [[User:Rfc|Rfc]] 18:58, 1 December 2009 (UTC)
:If one designs a pressure vessel to contain 0.5 atmospheres pressure, as might be adequate for a greenhouse, then the atmospheric pressure of Mars, 0.01 atmospheres helps to hold that pressure in so that the differential pressure is 0.49 atmospheres, or 98% of differential pressure for building such a greenhouse in a vacuum. Of course if one wants to maintain 1 atmosphere internal pressure, then the differential pressure on Mars would be 0.99 atmospheres.--[[User:Farred|Farred]] 07:01, 4 December 2009 (UTC)

The Eden Project is a really cool day out but I'm not convinced of the relevance to Mars exploration. It doesn't make reference to anything off-world, or even contained biospheres (in the way Biosphere 2 did).

People from Earth to Mars in 30 days

2013-09-28T20:44:32Z

Pete9804: Add headers, fixed a couple of typos

==Overview==
Using a combination of electric and chemical propulsion it is possible to send people in a rocket from Earth to Mars in 30 days. The electric portion of the system would accelerate nine refuelling depots to prepositioning orbits. The chemical rocket with a human crew would rendezvous with each of the nine refuelling depots, adding about 3056 m/sec in each of ten burns. The nine refuelling depots would be in nine independent orbits. The first would pass Earth at 3,056 m/sec, the second at 6,112 m/sec, the third at 9,168 m/sec and so on. The spaceship to Mars would accelerate to 3,056 and rendezvous with the first tanker just as it passes and likewise with each of the others in turn until it finally achieved the delta v for fast transfer to Mars This would follow an orbit of the same aphelion and perihelion as a Hohmann transfer orbit between Mercury and Saturn,<ref>W. Joseph Armento, ''PHYSICAL DATA FOR THE PLANETS, THEIR SATELLITES AND SOME ASTEROIDS'' in the CRC HANDBOOK of CHEMISTRY and PHYSICS, 64th edition, page F-140</ref> but with the inclination, longitude of ascending node and argument of perihelion needed to intersect Earth's and Mars' orbits. The change in velocity (delta v) necessary to change from Earth's orbit to the transfer orbit is 30,561 m/sec. This is just an example trajectory and there are probably transfer orbits that more efficiently use delta v and can make the 30 day transfer with less than nine refuellings. The fuel transfer technology still needs to be developed and practised to be sure that the fuel transfers and rocket restarts are accomplished without fail, lest the crew be stranded en route. To address the possibility of difficulties with timely, reliable transfer of fuel and difficulties with engine restart, the fuel could be transferred complete with a fresh set of tanks, fresh engine, plumbing and wiring in a stage swap with the tanker. In using this technique, there would be only a mechanical connection between the rocket stage and the Mars bound spaceship. The rocket stage would have its own electrical power and be controlled by radio signals over a short gap. The prepositioning of the fuel depots would begin long before the human crew is launched, on the order of ten years before.
==Implications==
A spaceship for a 30 day voyage could be smaller than one intended for a 180 day voyage because not as much air, food and water would need to be carried. Provision for refueling would add some mass and there would need to be a substantial heat shield for slowing down at Mars. The 30 day mission to Mars may be limited to a fly-by unless other refuelings are scheduled near Mars to cut down the velocity of the spacecraft some before it begins atmospheric braking at Mars. There is a limit to the peak deceleration loading that it is reasonable for humans to endure. The refuelings near Mars and the atmospheric braking in excess of human tolerance could both be done away with if one is willing to settle for a 38 day transfer when Earth and Mars are closest. This uses a modified transfer trajectory with only seven refuelings.
==Concerns==
A concern for the use of multiple refuelings during a journey through the solar system is the possibility of failure of one of the tanker craft to achieve its planned orbit. There have been some failures of ion engines during missions. However NASA is working on a new [http://www.nasa.gov/centers/glenn/about/fs22grc.html Magnetoplasmadynamic Thruster] which should solve the reliability problems. The new electric rocket uses hydrogen instead of Xenon. Since hydrogen is cheaper and available in much larger quantities than Xenon, it is a better choice for reaction mass for a tanker spacecraft. NASA writes that exhaust velocities approaching 100,000 meters per second can be achieved with noncondensable hydrogen plasmas, so a tanker using a Magnetoplasmadynamic Thruster should be able to achieve the delta v necessary for the planned rendezvous. If some failure did prevent a refueling tanker from being in the proper orbit, telemetry would indicate the failure long before the launch of the craft with a human crew. This failure would not cause loss of life because the launch could be aborted.
==Article notes==
Some people commenting on this article indicated that they thought the refuelings would be evenly spaced in time along the 30 day or 38 day trip. However, the refuelings would be bunched together near Earth for acceleration and a refueling near Mars for slowing down if needed. For most of the trip the rocket motor is unused and the spacecraft continues on in its transfer orbit. If two hours is allowed for each rendezvous, docking, stage swap and burn sequence in the 38 day trip, all acceleration would be completed in 16 hours at the start of the trip. Deceleration would be accomplished by atmospheric braking at Mars.
