		Kepler found that the orbits of the other planets could also be drawn as ellipses with the sun always at one of the foci.
		In 1620 Kepler's mother, who dabbled in the occult, was arrested as a witch and, although not tortured, did not long survive her release, which was procured through her son's long-sustained efforts.
		Kepler's final service to astronomy was his calculation of the times of passage of the inner planets Mercury and Venus across the face of the sun.

		The highlands are composed of a heavily cratered crust composed largely of anorthosite.
		The general Lunar crater morphology is directly related to the size of the crater.
		The central peaks of large impact craters such as Copernicus may be composed of rocks that have been uplifted from deep in the crust.

		Craters are the oldest common features found throughout the solar system [16], and in fact, the largest known crater in the system is known to be on the moon.
		The study of craters and lunar geology in general was at it's height during NASA's lunar missions in the 1960's.
		Measuring the true depth of craters is increasingly difficult as one must make a determination between the measurement from the lunar surface to basin of the crater rather then the from the height of the crater rim.

	Impact craters
		This is the excavation stage when the material excavated from the crater is distributed radially as a blanket of fragmented debris or "ejecta".
		Craters are a most useful tool to establish the relative ages of surfaces and thus to better understand how a planet has evolved, for example, to learn what have been the rates of erosion and sedimentation.
		The martian chronology is a relative chronology by comparison to the lunar one which is absolute and was calibrated by datation established on the lunar samples brought back by the Apollo missions.

		While Reiner Gamma is typical of the lunar swirls, it must be noted that it is not located at the antipode of a major basin, although some argument can be made as to its antipodal source being the far side feature Tsiolkovsky.

		The hills on the lower right of the mosaic are the central peak of the crater, with a height of roughly 1.2 kilometres.
		Gassendi is a scientifically interesting site because it offers lunar landers the possibility of sampling ancient highland rocks (in the crater's central peak) as well as providing ages for both the Humorum impact basin and the Gassendi crater itself.
		The western part of the crater floor, away from the geometric continuation of the western edge of Mare Humorum, is composed of highlands-rich material.

		Lunar Orbiter V photographs are used in the analysis of craters Messier and Messier A. Elston, Donald P., and Charles R. Willingham.
		Initial analysis of Lunar Orbiter photography indicates that the flow has a thickness of at least 20 meters at a point about 4 kilometers east of G in the superimposed schematic on the photograph.
		Lunar Orbiter IV photography of Mare Humorum, at a ground resolution of 54 meters, shows no unusual surface structures which would support the belief that the anomaly is caused by low-thermal-inertia material.

	Astrophotography by Anthony Ayiomamitis
		Named after the German astronomer Johannes Kepler, this 31-km diameter crater lying in Oceanus Procellarum is one of a small number of craters which basically lies in isolation and is relatively young with an estimated age of less than 1.1 billion years.
		Inspection of the image below reveals several interesting features including an explicit surrounding ray pattern indicative of an impact of some sort; a shadow pattern which is a reflection of the nearly 3-km high surrounding walls; a slight suggestion of a central relief; and various craterlets and domes in all four directions.
		The impressive twin craters to the north are Herodotus and Aristarchus; crater Euler is at the northeast corner of the image whereas crater Lansberg is the large formation on the southeast corner.

		Shortly thereafter we were joined by the American Lunar Society and a number of other astronomical organizations (See Table 1) and the International Bright Lunar Rays Project was born.
		Digital imaging is a major factor in the recent resurgence in lunar observing and is particularly well suited to the project.
		His notes, in part, read: “Two linear rays from Kepler to the east intruded onto the mare floor to the east of Suess B and D. Both rays faded in tone as they approached the wrinkle easterly ridge and could not be traced across them.”

		Crater Kepler has spewed out ejecta in ALL directions, and any form and shape can happen when it all comes dropping down; some masses falling upon others causing odd clusters, which SEEN from an angle can LOOK like an artificial construction.

		We have developed methods of describing impact crater morphology using eigenfunction expansion methods to decompose the shape into individual shape components.
		One of the key findings from this research is that small asymmetries are present in impact craters formed by bodies impacting at oblique angles.
		Although the crater is not perfectly symmetrical, it is hard to identify and interpret the asymmetries.
