	Mare Tranquilitatis
		Mare Tranquilitatis is probably the most well remembered lunar feature from my generation.
		On the lower left (east) edge is Mare Crisium and the bright crater Proclus.
		Left of Theophilus is Mare Fecunditatis and the pair of bright craters, Messier and Messier A. The bright ray stretching to the west of Messier is commonly nicknamed "the comet".

		The Moon - Mare Serenitatis and Mare Tranquilitatis border, 5 April 2006
		This picture shows the border between the Mare Serenitatis (the Sea of Serenity, to the upper-left of the picture) and Mare Tranquility (the well-known Sea of Tranquility, to the lower right of the picture).
		The contrast between the different mare lavas can be even more clearly seen on this enhanced-colour image.

		Rupes Recta is a linear fault scarp in the Mare Nubium to the South West of the three-crater sequence of Ptolemarus, Alphonsus, and Arzachel, and is sometimes known as the "Straight Wall".
		The whole Mare is dotted with craters and traversed by lava snakes, but most promenant are the vast bright rays that shoot across from craters Copernicus, off the picture to the south (although the mountains around it, Montes Carpatus, are clear), and Aristillus, to the Northeast of Archimedes on the lower right of the picture.
		Intersecting Mare Nectaris to the south is the 128km wide walled plain Fracastorius, whose remaining walls and slopes (lost to Mare Nectaris in the north) are dotted with craters and small craterlets.

		Mare Crisium: (North - South) a lava filled basin from the Nectarian Period.
		Mare Imbrium: One of the youngest multi-ring basins, whose lava flooding covered most of the inner rings.
		Mare ridges, inside the crater, likely mark the central peaks (where subsidence was the least).

	Plinius
		is a prominent lunar impact crater lies on the border between Mare Serenitatis in the north and Mare Tranquilitatis in the south.
		South-southeast of Plinius is Ross crater, and to the northeast is Dawes crater.
		The sharp rim of the Plinius crater is slightly oval in form, with a terraced inner wall, and an irregular outer rampart.

		In the south eastern corner, between 4 and 5 o'clock, Mare Australis is visible (Rukl 76).
		To the southeast of Sinus Iridum in the Mare Imbrium, lie two smaller craters, Helicon (Rukl 10) with a diameter of 25 kilometers and Le Verrier (Rukl 11) with a diameter of 20 Kilometers.

	Mare Crisium (Site not responding. Last check: 2007-11-02)
		It is situated near the eastern limb of the Moon and is the first of the giant, lava-filled impact basins to become visible after new moon.
		Just to the right (west) of Mare Crisium is the bright rayed crater Proculus, while further to the west is Mare Tranquilitatis.
		Almost in the centre of Mare Fecunditatis, is the pair of bright craters, Messier and Messier A. The bright ray stretching to the west of Messier is commonly nicknamed "the comet".

	photo of the week
		In July of 1969, the Apollo 11 astronauts landed in Mare Tranquilitatis, a huge impact crater formed in the lunar crust about 4 billion years ago that had been flooded by basaltic lavas 3.6-3.9 billion years ago.
		The Apollo 11 mission landed in a mare because mare are flatter and, consequently, safer places to land than the surrounding highlands.
		At the time of the Apollo 11 mission, little was know about the crust of the more rugged lunar highlands, although the unmanned Surveyor VII mission in 1968 had suggested that the highlands were rich in aluminum.

		As part of a lunar Mare this region consists primarily of basaltic lava.
		The lava flow is a relatively young event the occurred after the main period of crater formation.

		Gassendi A and B were very easy to detect, and on the southern edge of mare Humorum, Doppelmayer was visible.
		There I found, between Mare Crisium and Mare Tranquilitatis, Palus Somni or the marsh of sleep (Rukl 26, Hatfield 3 d4).
		After looking into our different moon atlases we agreed that it had to be Mare Marginis (Rukl 27, Hatfield 3 a4), which lies on the very edge of the lunar nearside.

		Only one LTP (Cameron,1978, No. 393) was observedin the Mare Tranquilitatis (except the Mare Serenitatis Border) before the first probe impact of Ranger 6 on February 2, 1964, about 50 km to the south of the crater Ross.
		This local "wave" of LTP reports is statistically significant Indeed, n=31 LTP in the Mare (in the borders from Fig.1) were reported from February 2, 1964 to September 25, 1969 (Cameron,1978).
		Therefore, the average probability of LTP in the Mare is p=32/1464.

		This feature, which is not a bridge at all, is on the western (selenographic coordinates) side of Mare Crisium.
		I studied what turned out to be the area between Mare Tranquilitatis and Mare Fecunditatis (only 1/4 of which was in sunlight), trying to make it look like the edge of Crisium, but I could never quite succeed.
		Finally, I thought I recognized Mare Serenitatis and Mare Tranquilitatis, with the prominent crater Plinius between them.

		The dark spot at upper right is Mare Moscoviense, the dark area at lower left is Mare Smythii.
		Astronaut Eugene Cernan is quoted as saying "We spent most of the way home, discussing what color the moon was." The moon has subtle colors, and between the glare of the surface, the astronauts' UV visors, and the psychology of sight, the question of color is more difficult than it would appear.
		At the center is Mare Orientale, barely visible from Earth on the limb of the Moon.

		One sure way of doing this is to locate the base in an area that can easily be identified by the trained naked eye, or at least in binoculars.
		This oval Mare, the size of Wisconsin and Upper Michigan together, is clearly distinct from the "chain of seas" that run into each other: Fertility, Tranquility, Serenity, Rains, the Ocean of Storms, etc. I am aware of no one else who is partial to Crisium.
		As the mare basin-filling lava sheets were laid down in distinct episodes with lava tubes likely forming in each layer, there may be many intact lavatubes well below the surface layers in some lunar seas.

		The Mare Tranquilitatis, the Mare Foecunditatis and the Mare Nectaris form Rabbit's head and ears, his tail formed by Mare Nubium.
		Some say that the Mare Imbrium is an egg held between Rabbit's paws.
		Another suggestion is the fact that it takes 28 days, one lunar month, before newborn Hares are ready to leave their mother.

		I suspect this is the easier of the two complexes, as it showed quite as well but the light was not as favorable.
		The classic rille structure is formed around the edge of a mare, or the edges and center of a large crater (probably a slumping effect).
		Perhaps the most spectacular example is Rima Sirsalis, but these groupings near Mare Nectaris and Tranquilitatis are in their own way equally as fascinating, in that they both have tripartite parallel runs.
