Albategnius-2.jpgAlbategnius Crater (2)121 visiteAlbategnius (Al-Battani, Muhammad ibn Jabir) (approx. 850-929)
--------------------------------------------------------------------------------
An Iraqi prince, born in Batan, Mesopotamia (Iraq), who was the leading Astronomer and Mathematician of his time. He drew up improved tables of the Sun and Moon, measured the eccentricity of Earths orbit and the inclination of Earths Equator to its orbital plane. He was capable of making an extremely accurate measurement of the length of the Earth year - which was also used in the Gregorian reform of the Julian Calendar. His observations at Rakku, made over (probably) a 40-year period, were summarized in his work "Movements of the Stars" (first published in Europe in 1537).
Thanks to his contribution, Johannes Hevelius (1611-1687) was able to theorize and discover the secular variation in the Moons motion.

Enceladus-PIA10562.jpgCrescent Enceladus53 visiteCaption NASA:"In the boundary between light and shadow on Enceladus, run the Anbar Fossae a series of narrow, shallow depressions.
Like other features on this geologically active moon, the fossae are named after a location in The Arabian Nights. In this case, they are named after Anbar, Iraq.
Another Iraqi namesake, the Baghdad Sulcus, is one of several warm `Tiger Stripe' fractures at the moon's South Pole from which emanate heat and icy particles (see also PIA11114).
North is up in this image, and Julnar is the largest crater visible in the Northern Hemisphere. One of the women in The Arabian Nights lends her name to this crater which is about 20 Km (about 12 miles) wide.
Fewer craters mark the Southern Hemisphere because they have been erased by later tectonic forces.
The image was taken in Visible Light with the Cassini Spacecraft narrow-angle camera on Dec. 17, 2008. The view was obtained at a distance of approx. 385.000 Km (about 239.000 miles) from Enceladus and at a Phase Angle of 104.
Image scale is roughly 2,5 Km (about 1,6 miles) per pixel".MareKromium

Luna-03.jpgThe Yutu-2 Rover from LRO73 visiteI dati sino ad ora in nostro possesso sono stati raccolti nel Cratere Von Krmn a partire dal 3 gennaio 2019 quando la navicella spaziale cinese Chang'e 4 atterrata al suo interno, cos diventando la prima Navicella Spaziale ad atterrare dolcemente sul lato (a noi) "nascosto" della Luna . Il Sito ha un valore simbolico oltre che scientifico. Theodore von Krmn (1881-1963) stato il consigliere di dottorato di Qian Xuesen , il fondatore del Programma Spaziale Cinese.
Il 4 febbraio 2019, la IAU ha approvato il nome del sito di atterraggio come Statio Tianhe . Il picco centrale del Crater Von Krmn, a nord-ovest del Sito di atterraggio, stato chiamato Mons Tai . Sono stati anche nominati tre piccoli crateri: Hegu, a sud del Landing Site, Zhinyu a Ovest e Tianjin a Nord-Est.MareKromium

SOL872-1152281618_30555-4_Sol872A_P2263_L456atc-A893R1-2.jpgThe Surface of Gusev - Sol 872 (Approx. True Colors; credits: NASA/JPL-Caltech)54 visiteCaption NASA originale:"Zhong Shang is an Antarctic base that the People's Republic of China opened on Feb. 26, 1989, at the Larsemann Hills in Prydz Bay in East Antarctica.
Allan Hills is a location where researchers have found many Martian meteorites, including the controversial ALH84001, which achieved fame in 1996 when NASA scientists suggested that it might contain evidence for fossilized extraterrestrial life. Zhong Shan was the given name of Dr. Sun Yat-sen (1866-1925), known as the "Father of Modern China".
Born to a peasant family in Guangdong, Sun moved to live with his brother in Honolulu at age 13 and later became a medical doctor. He led a series of uprisings against the Qing dynasty that began in 1894 and eventually succeeded in 1911. Sun served as the first provisional president when the Republic of China was founded in 1912".

ZZ-Mercury-Craters-Qi_Baishi_et_al_-PIA14398-PCF-LXTT.jpgTolstoj Basin (Enhanced Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)248 visiteThe various named features present in this color image, Qi Baishi, Hovnatanian, Kalidasa and Tolstoj, create a stunning depiction of Mercury's scarred and variable Surface. Tolstoj, the large basin in the bottom right of the image, represents the war and peace of its namesake's famous novel through its smooth, light-colored center and rough, dark blue exterior.
This image was acquired as part of MDIS's color base map. The color base map is composed of WAC images taken through eight different narrow-band color filters and will cover more than 90% of Mercury's Surface with an average resolution of 1 Km/pixel (0,6 miles/pixel). The highest-quality color images are obtained for Mercury's Surface when both the spacecraft and the Sun are overhead, so these images typically are taken with viewing conditions of low incidence and emission angles.
Date acquired: June, 27th, 2011
Image Mission Elapsed Time (MET): 217689462, 217689478, 217689458
Image ID: 433721, 433725, 433720
Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
WAC filter: 9 (1000 nanometers), 7 (750 nanometers), 6 (430 nanometers) as red-green-blue
Center Latitude: 11,69 South
Center Longitude: 178,1 East
Resolution: 1387 meters/pixel
Scale: the Inner Ring of Tolstoj is roughly 365 Km
