The International Astronomical Union (IAU) has approved the names Cankuzo and Luqa for two Martian craters.

Cankuzo
is a 51.0-km wide crater located at -19.4, 308.01.
The crater was named after a town in Burundi.

Luqa is a 16.5-km wide crater located at -18.22, 228.27.
The crater was named after a town in Malta.

Enhanced 3D Model of Mars Crater Edge Shows Ups and Downs

A dramatic 3D Mars view based on terrain modelling from NASA's Mars Reconnaissance Orbiter data shows "highs and lows" of Mojave Crater.
The vertical dimension is exaggerated three-fold compared with horizontal dimensions in the synthesised images of a portion of the crater's wall. The resulting images look like the view from a low-altitude aircraft. They reflect one use of digital modelling derived from two observations by the orbiter's High Resolution Imaging Science Experiment camera.

Listaverk frá Mars (myndasyrpa)

Frá árinu 2006 hefur Mars Reconnaissance Orbiter geimfar NASA sveimađ umhverfis Mars í tćplega 300 km hćđ. Um borđ í geimfarinu er HiRISE, öflugasta myndavél sem send hefur veriđ út í sólkerfiđ. Myndir HiRISE eru í senn stórglćsilegar og stórfurđulegar og líkjast oft á tíđum fegurstu listaverkum. Hér er ađ finna tuttugu ljósmyndir sem HiRISE hefur tekiđ síđustu árin af yfirborđi Mars. Sumar ljósmyndirnar eru svarthvítar, ađrar vísvitandi í fölskum litum til ţess ađ draga fram smáatriđi sem annars sćjust illa eđa alls ekki.

Mars featured large lakes of melted ice about 3 billion years ago, according to new research suggesting that the planet reached its present, dry state more recently than previously thought.
Observations by British scientists have indicated that a series of depressions near the Martian equator were formed by water in lakes up to 20km wide.
The lake beds have been dated to 3 billion years ago, showing that the surface of Mars was still wet during a period called the Hesperian Epoch.
While it is well-established that Mars was warm and wet during its early history, previous research has indicated that it lost its atmosphere and became cold and dry between 4 billion and 3.8 billion years ago.

Mars south polar region

Title: An evidence for solar activity influence on the meteorological processes in the south polar region of Mars during the great opposition in AD 1924
Authors: Boris Komitov

A time series of the Martian south ice polar cap mean diameter for the period July-December 1924 is investigated. The data are based on the high quality pictures, which are obtained by visual observations of 60 cm telescope in Hamburg Observatory during the great opposition of Mars in AD 1924. After removing of the seasonal trend (caused by the springtime regression of the cap) quasi 36 and 80-82 days cycles in residuals has been obtained. The sunspot activity spectra for the corresponding period is almost the same one. The local maximums of polar cap area residuals occurred about 10 days after the corresponding minimums of sunspot activity. The so obtained results are briefly discussed.

Once upon a time - roughly four billion years ago - Mars was warm and wet, much like Earth. Liquid water flowed on the Martian surface in long rivers that emptied into shallow seas. A thick atmosphere blanketed the planet and kept it warm. Living microbes might have even arisen, some scientists believe, starting Mars down the path toward becoming a second life-filled planet next door to our own.
But that's not how things turned out.
Mars today is bitter cold and bone dry. The rivers and seas are long gone. Its atmosphere is thin and wispy, and if Martian microbes still exist, they're probably eking out a meager existence somewhere beneath the dusty Martian soil.
