Discovery Quadrangle
The Discovery quadrangle (geography), quadrangle lies within the heavily cratered part of Mercury (planet), Mercury in a region roughly antipodal to the 1550-km-wide Caloris Basin. Like the rest of the heavily cratered part of the planet, the quadrangle contains a spectrum of craters and basins ranging in size from those at the limit of resolution of the best photographs to those as much as 350 km across, and ranging in degree of freshness from pristine to severely degraded. Interspersed with the craters and basins both in space and time are plains deposits that are probably of several different origins. Because of its small size and very early segregation into core and crust, Mercury has seemingly been a dead planet for a long time—possibly longer than the Moon.Trask, N.J. & Dzurisin, D. (1984).

Mercury (planet)
Mercury is the first planet from the Sun. It is a rocky planet with a trace atmosphere. While it is the List of Solar System objects by size, smallest and least massive planet of the Solar System, its surface gravity is slightly higher than that of Mars. The surface of Mercury is similar to Earth's Moon, heavily Impact crater, cratered, with expansive rupes system, generated from thrust faults, and bright ray systems, formed by ejecta. Its largest crater, Caloris Planitia, has a diameter of , which is about one-third the diameter of the planet (). Being the most inferior planet, inferior orbiting planet it appears in Earth's sky, always close to the Sun, either as a "morning star" or an "evening star". It stays most of the time the closest to all other planets and is the planet with the highest delta-v needed to travel to from all other planets of the Solar System. Mercury's sidereal year (88.0 Earth days) and sidereal day (58.65 Earth days) are in a 3:2 ratio. This relation ...

Al-Khansa
Tumāḍir bint ʿAmr ibn al-Ḥārith ibn al-Sharīd al-Sulamīyah (), usually simply referred to as al-Khansāʾ (, meaning "snub-nosed", an Arabic epithet for a gazelle as metaphor for beauty) was a 7th-century tribeswoman, living in the Arabian Peninsula. She was one of the most influential poets of the pre-Islamic and early Islamic periods. In her time, the role of a female poet was to write elegies for the dead and perform them for the tribe in public oral competitions. Al-Khansāʾ won respect and fame in these competitions with her elegies, and is widely considered as the finest author of Arabic elegies and one of the greatest and best known female Arab poets of all time. In 629, she went to Medina with a deputation from her clan and, after meeting the Islamic prophet Muhammad, embraced the new religion. Her poetry was later recorded by Muslim scholars, who were studying unaltered Arabic of her time in order to explicate the language of early Islamic texts. Life Al ...
