Mare Humorum, (3) a new estimate of basalt volumes within Humorum, and (4) a comparison of our results with those obtained by previous workers.

Methods The presence of highland material in the ejecta or interior of a crater in the mare indicates that the cratering event penetrated the mare Cited by: On the north edge of Mare Humorum is the large crater Gassendi, which was considered as a possible landing site for Apollo [citation needed] To the south are the floor-fractured Vitello crater, the partially flooded Doppelmayer, and the smaller Puiseux.

To the east are Hippalus crater Coordinates: 24°24′S 38°36′W /. Mare Humorum. Move your mouse over the picture to see the names of the various craters.

Mare Humorum is the most clearly demarcated of the maria in the western hemisphere, and is one of the most-clearly defined impact basins on the whole of the visible side of the Moon. Basalt thicknesses in mare basins have been determined using assumptions about the premare topography of partly buried craters and by comparison to the Orientale basin.

Differences in those assumptions have led to a factor of 4 difference in mare thickness estimates. Further, knowledge of thickness is restricted to areas in which buried craters are present.

Crater Copernicus: Mare Humorum: Crater Gassendi: Oceanus Procellarum: Crater Gimaldi: For those who don’t know, mares, which translate to seas, are the dark, flat areas on the Moon. They were formed from ancient volcanic eruptions. The mares are much younger than the surrounding areas because they have fewer craters than their surroundings.

Gassendi is an impact feature located on the near side of the Moon, at the northern edge of Mare Humorum. The crater is actually much larger. Gassendi is a large lunar impact crater feature located at the northern Craters in the Mare Humorum.

book of Mare was named after French astronomer Pierre Gassendi. The formation has been inundated by lava during the formation of the mare, so only the rim and the multiple central peaks remain above the outer rim is worn and eroded, although it retains a generally circular form.

The mountains surrounding it mark the edge of an old impact basin which has been flooded and filled by mare lavas. These lavas also extend past the basin rim in several places. Results of this Craters in the Mare Humorum.

book included (1) identifying craters and other explosures of highland material within the bounds of Mare Humorum, (2) identifying craters in the highlands adjacents to Mare.

Such a sinking of the mare may also explain the two large, partly flooded craters that seem to slope into Mare Humorum. (Earth-based telescopic photo from the Consolidated Lunar Atlas) Mare Moscoviense. This is an oblique image of the lunar farside. It shows the impact basin that holds Mare Moscoviense.

Mare Humorum, or 'Sea of Moisture', is a small circular mare on the lunar nearside, about kilometres across. The mountains surrounding it mark the edge of an old impact basin which has been. The lowest albedo (~–) in the Mare Humorum has been observed in Dark Mantling Deposits (DMD).

The superposed craters within the Mare Humorum exhibit distinctively higher albedo (~) in the crater interior. The low albedo regions indicate the occurrence of relatively mature and/or mafic compositions within the Mare Humorum.

On the north edge of Mare Humorum is the large crater Gassendi, which was considered as a possible landing site for Apollo Mare Humorum is a scientifically interesting area because it allows the study of the relationships among lunar mare filling, mare basin tectonics, and global thermal evolution to the major mascon maria – regions of.

Note the large fractures arcing around Mare Humorum on the right. These fractures are believed to mark a bending of the lunar surface due to the weight of Mare Humorum. Such a sinking of the mare may also explain the two large, partly flooded craters that seem to slope into Mare Humorum.

Mersenius is a lunar impact crater that is located to the west of the Mare Humorum, in the southwestern part of the the southwest is the crater Cavendish, and to the south-southeast lies ius is 84 kilometers in diameter and kilometers deep. It is from the Nectarian period, to billion years ago.

This crater, located in Mare Humorum, is relatively fresh and very bouldered. LROC NAC MLE, image width is m [NASA/GSFC/Arizona State University].

Why is this crater so bouldered. Bouldery craters are primarily the result of bolides impacting solid material. More cohesive materials produce larger boulders when they are impacted.

Humorum is filled with a thick layer of mare basalt, believed to exceed 3 kilometres in thickness at the centre of the basin. On the north edge of Mare Humorum is the large crater Gassendi, which was considered as a possible landing site for Apollo   This crater, located in Mare Humorum, is relatively fresh and very bouldered.

LROC NAC MLE, image width is m [NASA/GSFC/Arizona State University]. Bouldery craters are primarily the result of bolides impacting solid material. Basalt thicknesses in mare basins have been determined using assumptions about the pre-mare topography of partly buried craters.

Differences in those assumptions have led to a factor of two difference in mare thickness estimates. Further, knowledge of thickness is restricted to areas in which buried craters are present.

We have shown that craters in the mare sometimes excavate highland. Fig. The floor-fractured crater Gassendi ( km in diameter), located on the northern edge of Mare Humorum (Lu- nar Orbiter photograph LO IV- H2).

and fresh craters of about the same diameter (Figure 2). These differences represent estimates of vertical displacement as functions of radial distance for the floor-fractured craters. Crater sequence images available for download.

Four areas are now available: 1) Mare Humorum 2) Clavius 3) Ptolemaeus 4) Mare Nectaris/Fracastorius. I may make one or two more of these (western Mare Fecunditatis?) but the four done (Petavious, Fracstorius/Mare Nectaris, Ptolemaeus and Mare Humorum) are it for now.

For example, this crater is located to the north of Liebig J, a relatively young, bright-rayed crater in Mare Humorum. The Featured Image impact clearly occurred within the Liebig J ejecta blanket, which is less mature and therefore of higher albedo than the surrounding dark mare rock.

This crater ( km diameter) is located on the norhern border of Mare Humorum. Its floor is characterized by the presence of several rimae and central peaks.

On the northern side of Gassendi it is visbile the crater Gassendi A, so that the two craters resemble a diamond ring. Gassendi is an impact feature located on the near side of the Moon, at the northern edge of Mare Humorum. The crater is actually much larger than the field of view visible in this image.

Mare Nectaris: [SE/L13] The Nectaris basin was excavated billion years ago. The oldest features on the Moon formed prior to this event. Mare Nectaris is a classic example of a multi-ring basin. Tuesday night will reveal the attendant Rupes Altai, a high cliff that is a. Based on this crater excavation method, the basalt thicknesses in portions of Mare Humorum, Mare Smythii, Oceanus Procellarum, and Mare Imbrium were estimated by Budney and Lucey, Gillis and Spudis, Heather and Dunkin, and Thomson et al., respectively.

In general, these results are larger than the estimates derived from partially flooded. The relatively smooth basaltic floor of Mare Humorum extends to the south (up) and is pock marked by a number of small regular craters.

There are a number of escarpments and rille systems to the east (right) side of the Gassendi and Mare Humorum which are indicated in the annotated image. Bordered along the western and eastern sides by continental regions of irregular vely small, irregular lunar mare in the southern latitudes of the Moon, amidst the rugged terrain to the south of the larger Mare Humorum.

This composition contains many interesting and characteristic formations. Mare Humorum and a wax seal in the north, Gassendi crater. Ditch complexes in the west: Rimae Mersenius, Rimae de. And one more thing makes them interesting: they all have rille systems on their floors.

Craters like these were dubbed floor-fractured craters by Peter Schultz (now at Brown University), who found more than examples.

Posidonius (L20 in the Lunar ) is a kilometer-wide crater on the northeastern shore of Mare Serenitatis. The western section of Mare Humorum, with Crater Gassendi on its northern edge, is visible on the right side of the photograph, with the rugged, crater-pocked frontier dominating the region leading to the Moon's southwestern visible perimeter.

Note that many of the small and medium-sized craters south and west of Humorum in this sector are unnamed. The Mare is an important topographical unit while the impact crater is an important annular structure on the surface of the moon.

The purpose of this paper is to study the temporal and spatial distribution characteristics of impact craters in the mare area and lay a good foundation for further determination of impact events in the lunar mare area. The crater Gassendi is km in diameter and located on the northern edge of Mare Humorum at °S, °W.

Gassendi features an array of intersecting fractures on its floor, collectively known as the Rimae Gassendi. Some of the largest fractures are thousands of meters wide.

Homework Statement What was the diameter of the object that impacted the moon 3 to 4 billion years ago and created Mare Humorum Homework Equations N(t) = N0(1/2)n The Attempt at a Solution I'm completely lost by this question so I haven't attempted a solution yet but I think I'm.

Lunar Crater Gassendi - posted in Sketching: Protruding into the northern rim of Mare Humorum is the large floor fractured crater Gassendi. The km. walled plain crater is shallow as a result of lava upwelling across the floor especially toward the east where the highest concentrations of floor fractures are located.

The shallow south end is tipped facing the center of Mare Humorum. Region in the SW quadrant of the Moon's nearside between Mare Nubium (to the left) and Mare Humorum (to the right).

The large crater at the lower left is Bullialdus (38 miles diameter). Note the mountain-like formations in the center of the crater, produced by impact "bounceback.".
