Founded in the 9th cent., the city was formerly an important port but declined after the building (1819) of the Mahmudiyah Canal, which diverted its trade to AlexandriaAlexandria,

The Rosetta Stone is a granitoid slab inscribed in hieroglyphic, demotic, and Greek with identical texts of a decree by a council of priests during the reign of Ptolemy VPtolemy V
(Ptolemy Epiphanes) , d. 180 B.C., king of ancient Egypt (205–180 B.C.), of the Macedonian dynasty, son of Ptolemy IV. He succeeded to the throne as a small boy, and his reign began with disastrous civil wars.

(roh-zet -ă) An international ESA mission to rendezvous with a comet. It was approved in 1993 as a ‘cornerstone’ mission of ESA's Horizon 2000 program, and the original plan was to bring back to Earth samples taken from a comet's nucleus. The spacecraft was to consist of a cruising module coupled with a landing module and Earth reentry module. The object of the mission was later changed to an 18-month analysis of cometary material. Rosetta was scheduled for launch in 2003 to rendezvous with Comet 46P/Wirtanen in 2011. But the timetable for launch slipped by a year and this fact necessitated the selection of a different target. Thus on Mar. 2 2004 the 3000-kg Rosetta craft was launched from Kourou, French Guiana, by an Ariane-5 rocket and set to encounter Comet 67P/Churyumov-Gerasimenko in 2014. Rosetta's journey to the comet involves three gravity-assist flybys of the Earth and one of Mars. It will pass close to two asteroids, (2867) Steins and (21) Lutetia. Rosetta's task on reaching the comet will be to enter orbit around it and accompany it on its inward journey toward the Sun. The main Rosetta craft will deploy a lander called Philae, which will touch down on the comet's nucleus and carry out on-the-spot measurements of the chemical and physical makeup and properties of the nucleus and coma. It is hoped that these measurements will advance our understanding of the origin of comets, the relationship between cometary and interstellar material, and the implications of that relationship regarding the origins of the Solar System. The nominal end of the Rosetta mission will come when Churyumov-Gerasimenko passes through perihelion in late 2015.

(2) An emulator from Apple that ran PowerPC-based applications on Intel-based Macs under OS X. Included with Apple's first Core Duo-based laptops, Rosetta ran most OS X applications except for those that used specific instructions in the G5 processor. Named after the Rosetta Stone, which inscribed a decree in 196 BC of the Egyptian King Ptolemy V in three languages, the Rosetta emulator was discontinued in the Lion version of Mac OS X. See Mactel.
