<p>Anders Feder: </p> <hr /> <div>Flywheel batteries work by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. The energy is converted back by slowing down the flywheel.<br /> <br /> The space environment has a number of advantages for flywheel energy storage:<br /> * The natural vacuum eliminates energy losses due to atmospheric drag.<br /> * Cryogenic temperatures of space enable superconductor magnetic bearings that minimize friction in the system, without further refrigeration.<br /> * Energy losses due to friction, hysteresis etc. can be utilized to heat the spacecraft.<br /> * Due to the absence of living beings, minimal safety precautions, in case the spinning flywheel 'explodes', has to be made.<br /> * Because of their angular momentum, flywheels can act as reaction wheels for attitude control as well, even while storing energy.<br /> Furthermore, in vehicles, such as a lunar rover, flywheels can stabilize motion due to the gyroscopic effect.<br /> <br /> Current best theoretical energy densities of flywheel batteries are around 200 Wh/kg.</div>

<p>Anders Feder: </p> <hr /> <div>== Requests for information ==<br /> Hello, I am a volunteer of Team FREDNET coordinating communications with Lunarpedia. We regularly need information about the space and lunar environment to support development of our lunar mission, and would be very appreciative if Lunarpedia contributors are able to help us out. I'm adding requests for such information in the list below, in order of importance (most important at top). Not all requests for information are 'mission critical', but in any event it will help draw as complete a picture of the mission environment as possible.--[[User:Anders Feder|Anders Feder]] 13:56, 3 January 2009 (UTC)<br /> ==== Open requests ====<br /> * '''Radiation environment throughout mission'''. We need a thorough characterization of the radiation environment throughout a mission from the Earth to the Moon, including on Earth, in transit and on the Moon.

We need data on the thermal properties of the regolith at the Apollo and Lunakhod landing sites. Parameters of interest include thermal conductivity and solar absorptivity / emissivity. For the Apollo sites, these data should be available from NASA, based on soil samples taken by astronauts on the missions. For the Lunokhod sites, the data should be available from RKA (or secondary sources), based on soil samples returned robotically. --[[User:Anders Feder|Anders Feder]] 18:41, 19 February 2009 (UTC)<br /> * '''Calculating incident infrared radiation on lunar surface'''. This is more of a general physics problem than specifically a lunar science problem: how do you calculate the amount of infrared radiation emitted by the lunar surface that is incident on an area at the surface, such as the sides of our lunar lander?

If you model a very small piece of the surface then direction is irrelevant because energy is emitted in a uniform sphere.

We need to know the composition of the surface material at our landing site to calculate its frictional properties, which in turn will be used to design our rover. We have not selected a landing site yet, but it will most likely be one of the heritage Apollo landing sites.

<p>Anders Feder: New section: Which way to the Moon?</p> <hr /> <div>==Ideas for increasing Lunarpedia Contributors==<br /> *Ads in Moon Society publications?<br /> *Ads in NSS Publications such as Ad-Astra Magazine?<br /> *Ads in international space and astronomical society publications and other moon related projects?<br /> *Giving Aerospace/NewSpace companies the opportunity to write articles about themselves? (currently underway)<br /> *An article on Lunarpedia in Wikipedia?<br /> *Interview with SPACE.com?<br /> *A more eyecatching logo/banner on moon society websites?<br /> *Better placement of the logo/banner on moon society websites?<br /> <br /> Ideas Welcome!<br /> <br /> : Note: Wikipedia does not allow adverstising, promos for Lunarpedia on Wikipedia will probably be &quot;speedily deleted&quot;.[[User:Cfrjlr|Charles F. Radley]] 13:59, 16 March 2008 (UTC)<br /> <br /> ------------------------------<br /> <br /> The logo on the Moon soc web site needs to be rotated so the text is horizontal.<br /> Right now it is easy to ignore by accident, as the text is difficult to read.<br /> <br /> [[User:Cfrjlr|Charles F. Radley]] 19:50, 8 January 2007 (PST)<br /> <br /> ------------------------------<br /> A GIF banner concept I came up with. Same dimensions as lunarpedia logo.<br /> [[User:Jarogers2001|Jarogers2001]] 21:28, 8 January 2007 (PST)<br /> <br /> [[image:Lunarpedia1.GIF]]<br /> <br /> ----<br /> I like the bottom one, but I think you need to move the earth so it would show as a disc and perhaps a stylized crater or two on the moon would help. The basic idea is you have to be able to recognize it as a lithograph or silhouette. --[[User:Mdelaney|MikeD]] 09:26, 12 March 2007 (GMT)<br /> :I downloaded a program that was recommended to me to try and make this image and found out it crashed my system. I may be able to fall back on a picture with no animation but ill need to be pointed in the direction of an archive of high resolution moon pictures. [[User:Jarogers2001|Jarogers2001]] 06:47, 12 March 2007 (PDT)<br /> <br /> ==Artemis Databook==<br /> Is it possible to integrate articles from the Artemis Databook (ex: [http://www.asi.org/adb/05/04/modular-architecture.html http://www.asi.org/adb/05/04/modular-architecture.html]) in to lunarpedia without licensing issues?&lt;BR/&gt;&lt;BR/&gt;[[User:Jarogers2001|Jarogers2001]] 12:44, 10 January 2007 (PST)<br /> <br /> <br /> :No, but we need to reference it more often. Permission te release content to the public domain (merely licencing it won't work) would need to be done on an author by author basis as that's where the copyrights reside. -- [[User:Strangelv|Strangelv]] 18:48, 10 January 2007 (PST)<br /> <br /> <br /> ==Categories==<br /> <br /> The list of categories on the Special Page for Categories [[Special:Categories]] is different (much longer) than the list of Categories of interest on the Main Page [[Main_Page]]. It will be a pain to keep them in sync. I suggest we remove the list of categories from the main page, and put in a link to the Special Page instead. [[User:Cfrjlr|Charles F. Radley]] 05:40, 26 January 2007 (PST)<br /> :Maybe. I don't see it as a long term solution to use maintainer tools for casual users, however. What if we created a small number of supercategories and made sure that all content articles (pure disposable list articles and other overhead need not apply) were placed in at least one of them? Part of my concern about the maintenance tools is that in presents the user with a lot of stuff that is not of direct interest to them coequal or above (by virtue of alphabetization) articles of far greater relevance to someone seeking actual content. -- [[User:Strangelv|Strangelv]] 06:47, 26 January 2007 (PST)<br /> <br /> Is there an automated way of generating a list of only all categories which have content, and hiding the stub categories? [[User:Cfrjlr|Charles F. Radley]] 06:57, 26 January 2007 (PST)<br /> <br /> == Advertising is OK ==<br /> <br /> This needs to be reworded, the word &quot;advertising&quot; is what I have an issue with. The general sense of the paragraph doesn't worry me, just that word. -- [[User:Mdelaney|MikeD]] 09:18, 12 March 2007 (GMT)<br /> <br /> :Promotion? -- [[User:Jarogers2001|Jarogers2001]] 06:38, 12 March 2007 (PDT)<br /> <br /> == Sidebar ==<br /> <br /> I'd like to know what I can remove from the sidebar without causing undue hardship, it's currently a complete and utter shambles.<br /> <br /> Items I think can be removed are:&lt;br&gt;<br /> Under '''Navigation''':&lt;br&gt;<br /> *Category List A-Z&lt;br&gt;<br /> *Complex Search&lt;br&gt;<br /> <br /> Under '''Maintenance''':&lt;br&gt;<br /> Everything<br /> <br /> We could move the Maintenance links to a Maintenance page.<br /> <br /> -- [[User:Mdelaney|Mdelaney]] 14:00, 15 April 2007 (UTC)<br /> <br /> <br /> :At a minimum, we may want to have the regolith box and a link to regularly needed maintenance functions, possibly added to the navigation menu. -- [[User:Strangelv|Strangelv]] 17:41, 15 April 2007 (UTC)<br /> <br /> : The maintenance links could be pushed into the Community portal. [[User:Cfrjlr|Charles F. Radley]] 21:03, 15 April 2007 (UTC)<br /> <br /> ::I don't favor leaving the maintenance links in the sidebar at all, they're visible to guest users and present a cluttered appearance. If this was Joomla I'd make them visible to sysops only, but it's not. I'm not sure if we can easily implement group permissions in the sidebar. -- [[User:Mdelaney|Mdelaney]] 22:26, 15 April 2007 (UTC)<br /> <br /> :::Most of them aren't sysop specific, but things any serious contributor could stand to have easily accessible, especially ones inclined to help with the tedious tasks we've mostly been neglecting. As far as the Community Portal goes, we never really used it -- we might move all of its contents elsewhere and delete it or replace it with a redirect. -- [[User:Strangelv|Strangelv]] 01:21, 16 April 2007 (UTC)<br /> <br /> ::::Ok, here's a suggestion, how about we thin the sidebar out a bit, and rename some of the links so users have some inkling what they're about.<br /> <br /> ::::For example, &quot;List of lists of needed articles&quot; never made sense to me, Peter's Outline probably belongs further up in the Navigation menu. Are there other words we can use in place of Uncategorized or Undescribed? -- [[User:Mdelaney|Mdelaney]] 02:55, 16 April 2007 (UTC)<br /> <br /> :::::Feel free to think of a better name for the List of Lists, but we've gotten far more mileage out of that than Peter's outline. It would be nice for it to be no more than two easily reached clicks away, along with a lot of other things in that menu, most of which are already inconveniently accessible from the special pages menu (so if they,'re going to end up less convenient than they are from there, their continued grouping becomes less optimal -- and if the special pages menu becomes trivially reachable again, the main problem will again be finding them in the alphabetized list -- okay, maybe more clicks is still worth it for some of them) -- [[User:Strangelv|Strangelv]] 14:54, 16 April 2007 (UTC)<br /> <br /> ::::::Did you just argue against yourself and win? -- [[User:Mdelaney|Mdelaney]] 21:14, 16 April 2007 (UTC)<br /> <br /> I've added the banner section to the lower left side bar. I will be talking with Eric Douglas of the [http://amlunsoc.org American Lunar Society] to see if he wants a banner there since he put our link on the amlunsoc.org frontpage. I will attempt to pursue other link exchanges with groups such as FOGE and LPOD. Still gotta bug marsdrive to tie up a banner loose end on marspedia. - [[User:Jarogers2001|Jarogers2001]] 15:47, 4 August 2008 (UTC)<br /> <br /> == Which way to the Moon? ==<br /> <br /> Hello,<br /> I'm a volunteer of the registered Google Lunar X PRIZE contestant Team FREDNET, an open source project to land a rover on the Moon. Development of our lunar mission requires a good deal of research, and I was wondering if you Lunarpedians might be interested in lending us a hand, given our similar spirits of openness and common interest in lunar missions? If you're interested, I could add requests for information from our team somewhere here, so you could contribute any knowledge you may have or are able to find on the subject, and then let us apply it to our mission? The kind of knowledge we're in need of should also have general applicability to Lunarpedia. --[[User:Anders Feder|Anders Feder]] 02:35, 20 December 2008 (UTC)</div>
