Rhea (moon)

Rhea is the second-largest moon of Saturn and the ninth-largest moon in the Solar System. It is the second smallest body in the Solar System for which precise measurements have confirmed a shape consistent with hydrostatic equilibrium, after dwarf planet Ceres, it was discovered in 1672 by Giovanni Domenico Cassini. Rhea was discovered by Giovanni Domenico Cassini on 23 December 1672, it was the second moon of Saturn that Cassini discovered, the third moon discovered around Saturn overall. Rhea is named after the Titan Rhea of Greek mythology, the "mother of the gods", it is designated Saturn V. Cassini named the four moons he discovered Sidera Lodoicea to honor King Louis XIV. Astronomers fell into the habit of referring to them and Titan as Saturn I through Saturn V. Once Mimas and Enceladus were discovered, in 1789, the numbering scheme was extended to Saturn VII, to Saturn VIII with the discovery of Hyperion in 1848. Rhea was not named until 1847, when John Herschel suggested in Results of Astronomical Observations made at the Cape of Good Hope that the names of the Titans and brothers of Kronos, be used.

Rhea is an icy body with a density of about 1.236 g/cm3. This low density indicates. Although Rhea is the ninth-largest moon, it is only the tenth-most-massive moon. Before the Cassini-Huygens mission, it was assumed. However, measurements taken during a close flyby by the Cassini orbiter in 2005 cast this into doubt. In a paper published in 2007 it was claimed that the axial dimensionless moment of inertia coefficient was 0.4. Such a value indicated that Rhea had an homogeneous interior while the existence of a rocky core would imply a moment of inertia of about 0.34. In the same year another paper claimed the moment of inertia was about 0.37. Rhea being either or differentiated would be consistent with the observations of the Cassini probe. A year yet another paper claimed that the moon may not be in hydrostatic equilibrium meaning that the moment of inertia can not be determined from the gravity data alone. In 2008 an author of the first paper tried to reconcile these three disparate results.

He concluded that there is a systematic error in the Cassini radio Doppler data used in the analysis, but after restricting the analysis to a subset of data obtained closest to the moon, he arrived at his old result that Rhea was in hydrostatic equilibrium and had the moment inertia of about 0.4, again implying a homogeneous interior. The triaxial shape of Rhea is consistent with a homogeneous body in hydrostatic equilibrium rotating at Rhea's angular velocity. Models suggest that Rhea could be capable of sustaining an internal liquid-water ocean through heating by radioactive decay. Rhea's features resemble those of Dione, with dissimilar leading and trailing hemispheres, suggesting similar composition and histories; the temperature on Rhea is between 73 K and 53 K in the shade. Rhea has a rather typical cratered surface, with the exceptions of a few large Dione-type chasmata or fractures on the trailing hemisphere and a faint "line" of material at Rhea's equator that may have been deposited by material deorbiting from its rings.

Rhea has two large impact basins on its anti-Cronian hemisphere, which are about 400 and 500 km across. The more northerly and less degraded of the two, called Tirawa, is comparable to the basin Odysseus on Tethys. There is a 48 km-diameter impact crater at 112°W, prominent because of an extended system of bright rays; this crater, called Inktomi, is nicknamed "The Splat", may be one of the youngest craters on the inner moons of Saturn. No evidence of any endogenic activity has been discovered, its surface can be divided into two geologically different areas based on crater density. This suggests; the leading hemisphere is cratered and uniformly bright. As on Callisto, the craters lack the high relief features seen on the Mercury, it has been theorized. On the trailing hemisphere there is a network of bright swaths on a dark background and few visible craters, it had been thought that these bright areas might be material ejected from ice volcanoes early in Rhea's history when its interior was still liquid.

However, observations of Dione, which has an darker trailing hemisphere and similar but more prominent bright streaks, show that the streaks are ice cliffs resulting from extensive fracturing of the moon's surface. The extensive dark areas are thought to be deposited tholins, which are a mix of complex organic compounds generated on the ice by pyrolysis and radiolysis of simple compounds containing carbon and hydrogen; the January 17, 2006 distant flyby by the Cassini spacecraft yielded images of the wispy hemisphere at better resolution and a lower Sun angle than previous observations. Images from this and subsequent flybys showed that Rhea's streaks in fact

Mads Glæsner

Mads Glæsner is a Danish swimmer. He participated at the 2008 Summer Olympics in the 400 metre freestyle and the 1500 metre freestyle disciplines, his swimming club is Vallensbæk-VAT but he trains at the National Training Center in Copenhagen. He competed at the 2012 Summer Olympics in the 4 x 200 m freestyle relay. In June 2013, Glæsner was stripped of a gold and bronze medal from the 2012 World Short Course Championships after testing positive for levomethamphetamine. However, upon appeal to the Court of Arbitration for Sport, Glaesner's 1500-metre freestyle gold medal was reinstated based on the fact that a test after that race, two days after his initial positive test following the 400-metre free, was clean, he still forfeited the 400-metre freestyle bronze. Since he has competed at the 2016 Summer Olympics, in the 400 m freestyle

Brink–Wegner House

The Brink–Wegner House is a historic house located at 110 E. 4th St. in Pierre, South Dakota. The house was built in 1904 for Andrew C. Brink, a real estate contractor; the house's Shingle style design features a gambrel roof and a bay window with a cone-shaped roof on the second floor. Four different shingle designs are used to side the house above the first floor; the house's dining room features a mural on the ceiling, part of an interior the National Park Service called "one of the best period interiors in the State". In 1923, Henry C. Wegner, who owned the state's first automobile agency, bought the home; the house was moved from 109 South Highland Avenue to its current location in 1977. The house was added to the National Register of Historic Places on April 26, 1978
