Outgassing events in which [[Volatiles|volatiles]] are vented from deep in the lunar interior to the surface, specifically, [[radon]], [[nitrogen]], [[carbon monoxide]], and [[carbon dioxide]], may be the result of low level [[lunar volcanism|volcanic]] or [[lunar tectonics|tectonic]] events on the [[moon]], and are hypothesized to be the source of the tenuous [[lunar atmosphere]]. Knowing when and where these events occur may help us understand more about [[lunar tectonics]] and how the moon's atmosphere was formed.<br />
<br />
[[Carbon]] and [[Nitrogen]] are both vital elements which will have to be imported from earth or from [[carbonaceous asteroid|carbonaceous asteroids]]. If outgassing events can be predicted it may be possible to [[ISRU|utilize]] this valuable resource.<br />
<br />
The [[Alpha Particle Spectrometer]] aboard [[Lunar Prospector]] was designed to detect these events by tracking the [[alpha particle|alpha particles]] emitted during the decay of [[radon|radon 222]] and [[polonium|polonium 226]] (two increments immediately preceded by [[radium|Ra226]] in the decay series of [[uranium|U238]]). The APS data was obscured by solar activity during the mission, but may be viewable once the effects of solar activity have been filtered out. This task has not been done.<br />
<br />
[[ground penetrating radar|Ground Penetrating Radar]] studies have been made with wavelengths penetrating 10-20 meters via the [http://www.naic.edu/ Arecibo] and [http://www.gb.nrao.edu/ Green Bank] radio observatories, but deeper and higher resolution scans are likely needed to detect further sub-surface gas pockets. Radar dark areas in the 70cm band, termed "halos", have been detected around many [[impact crater]]s. An especially large halo has been detected around [[Aristarchus crater]] and encompasses much of the [[Aristarchus plateau]]. Aristarchus is the major source of recent outgassing events detected via [[radon|Radon 222]] activity. It has been suggested that the Aristarchus halo may be the result of subsurface ice deposits, but this has not been confirmed. Aristarchus is known to be an active outgassing site<ref>[http://www.space.com/scienceastronomy/070730_gassy_moon.html Lunar Flash Mystery Solved: Moon Just Passing Gas] By David Powell posted: 30 July 2007</ref>.<br />
<br />
Many observers have reported witnessing so called "[[Transient lunar phenomena]]" including many amateur Astronomers. The crew of Apollo 11 reported observing a TLP at the crater Aristarchus.<br />
<br />
Although the Moon is relatively inert geologically, the [[lunar atmosphere]] continues to be replenished by lunar outgassing events.<br />

<div>'''Autostub1''' is a script intended to generate over 9,300 location articles: sectors and also craters, maria, rille, and everything else in the available public domain database.<br />
<br />
==Specifications==<br />
{{Cleanup Section}}<br />
These are incomplete and based on what has been targeted for work to date. <br />
<br />
===Sectors===<br />
{{Spec Melt}}<br />
Sectors, aside from two exceptional cases (the poles), are 15 degrees by 15 degrees. The equator has a single ring of sectors between 7.5N and 7.5S. The two polar sectors are 15 degrees in diameter. The sectors line up horizontally against 267.2<SUP>(double-check needed)</SUP>E Mean Earth, or 0 degrees Mare Orientale.<br />
<br />
===Features===<br />
<br />
===Lunar Feature Articles===<br />
Box: Image:Mare Orientale Map GA03 400 8bit.png<br />
Name (from database column 2)<br />
Category (from column 23)<br />
Origin (from column 24)<br />
Map (see Map:Features below)<br />
Coordinates in Mean Earth and Mare Orientale coordinates<br />
Diameter (size?) (from column 10)<br />
Approval status (from columns 18 and 19)<br />
<br />
Description: givig rough simple location description, type of feature, what sector it is centered in and if the calculation says it's probably wholly within the sector.<br />
<br />
Also give alist of sectors that portions of the feature may be located in.<br />
<br />
If the feature is a major crater, give a list of satellite craters.<br />
<br />
If the feature is a satellite crater, give a link to its major crater.<br />
<br />
Give list of references listed in column 21 of the database.<br />
<br />
===Lunar Sector Articles===<br />
There is a sector box from a template. The box is presently specified to list both Mean Earth and Mare Orientale coordinates, but with a change of the template all sector articles could display only one or the other, or change the way in which the information of both is presented. <br />
<br />
At the top of the box is the sector designation, which is presently no longer specified, as it would be good to have a naming system that not only doesn't present a point location to represent a far larger area, but also doesn't invoke either Mare Orientale or Mean Earth as its definitive basis.<br />
<br />
Below is a map as specified in Maps:Sector below.<br />
<br />
Below the map is the center coordinates in both Mean Earth and Mare Orientale.<br />
<br />
Below is a list of adjoining sectorImage:Mare Orientale Map GA03 400 8bit.pngs. Four for all non-polar sectors and twenty-four for the poles.<br />
<br />
The article text begins with a rough, simple description of where the sector is.<br />
<br />
Places of interest are listed, including features centered inside the sector and features that may be in the sector but are centered elsewhere.<br />
<br />
Another section should include surveys and landings, with where to click to get specific geological information. The mechanism to do this is not yet worked out.<br />
<br />
<br />
<br />
===Maps===<br />
<br />
====Source====<br />
{{Spec Melt}}<br />
Three source maps are needed. One for the 25 northernmost sectors, one for the 25 southernmost sectors, and one for all other sectors. Feature edge cases should probably be served by an outer portion of the relevant polar map. <br />
<br />
The polar source maps are not yet produced. A smaller version of the main source map can be found [[:Image:Mare Orientale Map GA03 400 8bit.png|here]]. The full-sized single layer version is 7200 by 2700 pixels and 40 MB compressed. It is calibrated for Mare Orientale coordinates.<br />
<br />
FIELD_MESSAGE_trsitget<br />
<br />
====Feature====<br />
Feature maps use the diameter to estimate the size of the map to be generated. Features below a to be determined size will not be feasible to include maps for from the source maps.<br />
<br />
===Output===<br />
Output is to be in the format used for exporting and importing articles between MediaWiki installations. Each output xml file should be below 2MB (or a to-be-determined more precise size target) to minimize difficulty importing. Test1 was imported in this manner.<br />
<br />
===Database===<br />
The database formatting is outside of the control of this specification. The database was created by the [[USGS]].<br />
