       Hi gang,

       please,anybody could tell me the name of the lunar sea on which the
Alphans has built the base?
       The names the seas more important (maria,in latin) are:

       Oceanus Procellarum
       Mare Imbrium
       Mare Crisum
       Mare Orientale
       Mare Serenitatis
       Mare Nectaris
       Mare Smythii
       Mare Humorum
       Mare Tranquillitatis
       Mare Nubium
       Mare Fecunditatis

      Tank you

I'm not by my reference material right now. Will check tonight. But that's why they were so worried during "The Last Sunset". With any amount of rain, a crater would fill up fast.

According to Starlog's Moonbase Alpha Technical Manual, Alpha is located " the crater Plato, just above the Sea of Showers on what was once called the 'nearside of the moon.'" Of course whether this sometimes "imaginative" source should be considered canon is a matter of personal choice. To me it seems as good as anything else in this instance since I don't recall Alpha's location being mentioned specifically in any of the episodes. Robert

Conversely, since I can't make out the continents on that cloudy crescent Earth, Alpha could be in the far Southern Highlands, which have lots of craters. You can understand this because, if Alpha were on the Moon's equator, in the middle of the near side, then the Earth would be directly overhead, and not near the horizon. The Moon doesn't spin relative to the Earth, so the Earth hangs is virtually the same spot of the lunar sky all of the time. Earth neither rises not sets on the Moon, although the Sun does. Since the Earth is near the Lunar Horizon from Alpha, then Alpha must be somewhere closer to the "edge" of the moon rather than the center of the moon, as seen from Earth. If the tips of the crescent Earth pointed down toward the Lunar horizon, or upward away from the lunar horizon, like a letter "U" then Alpha would be located on either the east side of the Moon's edge, as seen from earth, or on the far west side. But as seen in "Breakaway", the tips of the crescent Earth (also can be called the "horns") are aligned vertically to the lunar horizon, like a reversed letter "C". This puts Alpha either near the Lunar North Pole, or the Lunar South Pole. Of course, Brian Johnson made most of the crescent or gibeous planets look upright, with their Poles at the top and bottom of the TV screen. And everything (planets, Black Sun, Darian ship, etc), as seen from Alpha was near the lunar horizon. Whether they ever had a specific lunar location in mind is still very debatable. Ronald
