In this paper, we will deal with one of the most fascinating problems of the Solar System: the origin of the double face of Iapetus, where one half of the satellite is significantly brighter than the other. The “transfer of mass” process (see Marchi et al. 2001) may be a viable explanation for the visible dichotomy. In this process a satellite undergoes mass transfer from other satellites belonging to the same system. We analyze the pair Hyperion–Iapetus and suggest a possible explanation for the formation of the dark region, which is also known as Cassini Regio. Key words. minor planets, asteroids – solar system: general 1. Introduction 2. Transfer of mass Iapetus’ surface is divided into two parts: one with a very In a previous paper (Marchi et al. 2001), we have studied low albedo, about 0.015–0.05, which covers about a third the efficiency of mass transfer between pairs of satellites of the whole surface; the other with an albedo of about 0.5 in the whole Solar System. -

The presence of water has long been seen as a key condition for life in planetary environments. The Cassini spacecraft discovered water vapour in the Saturnian system by detecting absorption of UV emission from a background star. Investigating other possible manifestations of water is essential, one of which, provided physical conditions are suitable, is maser emission. -

For other uses, see Wiraqucha (disambiguation). Viracocha is the great creator god in the pre-Inca and Inca mythology in the Andes region of South America. Full name and some spelling alternatives are Wiracocha, Apu Qun Tiqsi Wiraqutra, and Con-Tici (also spelled Kon-Tiki) Viracocha. Viracocha was one of the most important deities in the Inca pantheon and seen as the creator of all things, or the substance from which all things are created, and intimately associated with the sea.[1] Viracocha created the universe, sun, moon, and stars, time (by commanding the sun to move over the sky) and civilization itself. Viracocha was worshipped as god of the sun and of storms. He was represented as wearing the sun for a crown, with thunderbolts in his hands, and tears descending from his eyes as rain. Cosmogony according to Spanish accounts According to a myth recorded by Juan de Betanzos,[2] Viracocha rose from Lake Titicaca (or sometimes the cave of Paqariq Tampu) during the time of darkness to bring forth light. -

We find that the satellites have a wide variety of different surface colors, from the negative spectral slopes of the two retrograde satellites S IX Phoebe (S0 = −2:5 ± 0:4) and S XXV Mundilfari (S0 = −5:0 ± 1:9) to the fairly red slope of S XXII Ijiraq (S0 = 19:5 ± 0:9). We further find that there exist a correlation between dynamical families and spectral slope, with the prograde clusters, the Gallic and Inuit, showing tight clustering in colors among most of their members. The retrograde objects are dynamically and physically more dispersed, but some internal structure is apparent. Keywords: Irregular satellites; Photometry, Satellites, Surfaces; Saturn, Satellites. 3 1 Introduction The satellites of Saturn can be divided into two distinct groups, the regular and irregular, based on their orbital characteristics. -

The Chaotic Rotation of Hyperion*
ICARUS 58, 137-152 (1984) The Chaotic Rotation of Hyperion* JACK WISDOM AND STANTON J. PEALE Department of Physics, University of California, Santa Barbara, California 93106 AND FRANGOIS MIGNARD Centre d'Etudes et de Recherehes G~odynamique et Astronomique, Avenue Copernic, 06130 Grasse, France Received August 22, 1983; revised November 4, 1983 A plot of spin rate versus orientation when Hyperion is at the pericenter of its orbit (surface of section) reveals a large chaotic zone surrounding the synchronous spin-orbit state of Hyperion, if the satellite is assumed to be rotating about a principal axis which is normal to its orbit plane. This means that Hyperion's rotation in this zone exhibits large, essentially random variations on a short time scale. The chaotic zone is so large that it surrounds the 1/2 and 2 states, and libration in the 3/2 state is not possible. Stability analysis shows that for libration in the synchronous and 1/2 states, the orientation of the spin axis normal to the orbit plane is unstable, whereas rotation in the 2 state is attitude stable. Rotation in the chaotic zone is also attitude unstable. A small deviation of the principal axis from the orbit normal leads to motion through all angles in both the chaotic zone and the attitude unstable libration regions. Measures of the exponential rate of separation of nearby trajectories in phase space (Lyapunov characteristic exponents) for these three-dimensional mo- tions indicate the the tumbling is chaotic and not just a regular motion through large angles. As tidal dissipation drives Hyperion's spin toward a nearly synchronous value, Hyperion necessarily enters the large chaotic zone. -

Inca Civilization 1425 A.D - 1532 A.D
Inca Civilization 1425 A.D - 1532 A.D The Inca first appeared in the Andes region during the 12th century A.D. and gradually built a massive kingdom through the military strength of their emperors. Known as Tawantinsuyu, the Incan empire spanned the distance of northern Ecuador to central Chile and consisted of 12 million inhabitants from more than 100 different ethnic (cultural) groups at its peak. Well-devised agricultural and roadway systems, along with a centralized religion and language, helped maintain a cohesive (solid) state. Despite their power, the Inca were quickly overwhelmed by the diseases and superior weaponry of Spanish invaders, the last bastion of their immense empire overtaken in 1572. The Inca first appeared in what is today southeastern Peru during the 12th century A.D (1100’s). According to some versions of their origin myths, they were created by the sun god, Inti, who sent his son Manco Capac to Earth through the middle of three caves in the village of Paccari Tampu. After killing his brothers, Manco Capac led his sisters and their followers through the wilderness before settling in the fertile valley near Cusco circa 1200. The expanding reach of the Inca state, lead to the need for information and people to travel quickly throughout the empire. Pachacuti Inca Yupanqui is believed to have been the first Inca emperor to order forced resettlement to squash the possibility of an uprising from one ethnic (cultural) group. In addition, he established the practice in which rulers were prevented from inheriting the possessions of their fathers, thereby making sure that new leaders would conquer new lands and accumulate new wealth of their own. -

Ranging from the earliest cities in the Americas to Inca metropolises, millennia of urban human history along the Andes have left large and striking sites scattered across the country. But cities and monuments do not exist in solitude. Peru’s ancient sites are connected by a vast circulatory system of roads that connected every corner of the country, and thousands of square miles beyond its current borders. The Inca road system, or Qhapaq Ñan, is particularly famous; thousands of miles of trails linked the empire from modern- day Colombia to central Chile, crossing some of the world’s tallest mountain ranges and driest deserts. The Inca state recognized the importance of its road system, and dotted the trails with rest stops, granaries, and religious shrines. Inca roads even served directly religious purposes in pilgrimages and a system of ritual pathways that divided the empire (Ogburn 2010). This project contributes to scholarly knowledge about the Inca and Pre-Hispanic Andean civilizations by studying the roads which stitched together the Inca state. -
