Astronomy lecture.Western Mare Crisium.Pictures by telescope

These captures of western Crisium sea through the telescope, are presented in another article: Video by astronomical telescope-near Western Mare Crisium.
There are many present craters on this large area, and I will only talk about features that were not discussed before.

We start with Burkhardt crater (57 km), which is located between craters Geminus (86 km), on north, and Cleomedes on south.
Burckhardt is located on two slightly smaller-sized craters on the opposite sides, producing a triple crater formation. Burckhardt E (39 km), is covered by the southwest quadrant of Burckhardt's, while Burckhardt F (43 km), is covered by the northwest quadrant. Crater rim is circular, but somewhat irregular in shape. There is a central peak near the midpoint of the crater floor.

Stucked in the western edge of the crater Cleomedes, is Tralles, and to the east of Cleomedes is the crater Delmotte (32 km), a small crater, whose characteristics are difficult to see because of its position.

Continue to the next photo description below, are craters Macrobius and Tisserand, 64 and 37 km, crater ray Proclus (28 km), and west of Proclus is Palus Somni , an area of 143 km,.

In the third picture below, there are many small craters on the surface of the sea, but also on its edge.
Peirce crater (19 km) with Picard (23 km), are those who are most "into the sea" of Crisium.
Picard's interior has a series of terraces, which seismologists have attributed to a collapse of the crater floor. The lowest point of the crater floor is about 2000 meters below its rim, and has a small hill in the center.

Other craters located further to the edge of the sea are Yerkes (36 km), Lick (31 km), Greaves (14 km), and Glaisher crater (16 km).

Yerkes crater (36 km), it seems interesting, because its inside was almost completely flooded by lava, leaving only a shallow remnant edge above the sea, and the edge is the most visible in west. The floor has a similar albedo with the large Crisium sea, so Yerkes's features are not distinct by surroundings.

About craters Firmicus (56 km) and Apollonius (53 km), I will speak in another article dedicated to them.

Moonscape of these pictures, captures Cleomedes crater (126 km), as I have not never seen it like that on this phase of the Moon. Where in total darkness begins, right there is not the edge of the Moon, but the terminal, the border between light and shadow.

Cleomedes, is also in darkness, but are visible many features that I have not seen before. Notice the eastern edge of the crater interior, with irregular terraces, and also the peak of the center, being lit only the top of it, peak which is surrounded by total darkness.


   Northwest of Cleomedes, are two craters, in the dark here, called Tralles (43 km) (who is "riding" on the edge of Cleomedes), and Debes (31 km) farther northwest. North of Cleomedes, notice Buckhardt crater (57 km), which overlaps Buckhardt E (39 km) is smaller, which remained only half a crater.


Further up north (in the first two pictures in the article) is another dark "pit" situated at the terminal. This is Geminus (86 km), a circular crater with beautiful terraced inner edges.


In the center of photos, notice a vertical line as a smooth plateau with irregular shape, which I guess is an extension of Lacus Bonitatis, located in the bottom of images. On the left in the picture, notice a crater though not large in size, stands out among other small craters. This is called Newcomb (39 km), and to its south is Newcomb J (23 km). Newcomb's floor is very mountainous. On the floor, stuck on the southern edge, is Newcomb A (19 km), a small but deep crater.


Images are Registax processings of a video that have taken a variety of frames, at several levels of quality, merged to form a single image.

        Cleomedes (126 km), is a large lunar crater located on the north-east of the moon, on northern Mare Crisium. Terrain is surrounded by many impact craters. Irregular crater Tralles (43 km), is entering in the northwest edge. To the east is Delmotte (33 km). North of Cleomedes is Burckhardt (57 km).

Outer wall is heavily eroded and worn, especially along the south wall. Cleomedes C (14 km), is located on south-western edge.
Crater floor is almost flat, with a small central peak located north of the midpoint, forming a linear ridge to the northeast. There are several notable small craters on the floor, including a pair of overlapping craters on northwest rim: Cleomedes A, E.

List of east features of the Moon. astronomy lecture

East of the Moon is marked by several interesting features. Most notably is Mare Crisium, a "sea" visible from the Earth with the naked eye as an isolated spot by other seas, dark in colour.
 Notable craters on the east side of the Moon are Posidonius, Petavius ​​and Langrenus, which are the largest in size.
 Even if it seems that East of the Moon has not too many huge craters, actually there are many  small craters as we can see in the list below.

Space missions on the east side of the Moon.

Apollo 16 (1972) with people on board. Apollo 16 was the tenth mission in the Apollo program with humans. It was launched on 16 April 1972 and ended on 27 April. It was a lunar rover mission and brought back 94.7 kg of lunar soil and rock samples.

Apollo 17 with people on board. EVA activity (EVA). Apollo 17 was the 11th and last  manned mission of the Apollo space program. Launched at 12:33 a.m. on 7 December 1972, with a crew of three members: Eugene Cernan, Ronald Evans and Harrison Schmitt. Apollo 17 landing remains the most recent made ​​beyond Earth's orbit.

 Luna 21 (1973) USSR (Union of Soviet Socialist Republics), has successfully carried on the lunar surface rover Lunakhod 2 on January 15, 1973. It sent back 86 panoramic images and over 80,000 TV pictures.

Ranger 8 (1965) USA - intentionally crashed. Launched on February 20, 1965. Ranger 8 successfully sent 7137 images with a resolution of up to 1.5 m.

Surveyor 5 (1967) successfully landed. It sent more than 19,000 images to Earth, and has conducted more than 100 hours of compositional analysis of the surface.
