Rocky mounds and a plateau on Mars468-20100306-6547-6-co-01-MagelhaensCrater_L.jpgMagellan Crater on Mars

When Mars Express set sail for the crater named after Portuguese navigator Ferdinand Magellan, it found a windblown plateau and mysterious rocky mounds nearby.
Stretching across 190 x 112 km, this region of Mars covers an area of about 21280 sq km, which is roughly the size of Slovenia. It is located to the southwest of the volcanic region Tharsis on the southern highlands of Mars, near the crater Magellan.

Seven years of Mars Express - unusual structures at Magellan Crater

In the southwest of the Tharsis volcanic region on Mars is the large impact crater Magellan, named after the Portuguese explorer Ferdinand Magellan (1480-1521). The High Resolution Stereo Camera (HRSC), carried by ESA's Mars Express orbiter and operated by the German Aerospace Centre (Deutsches Zentrum fr Luft- und Raumfahrt; DLR), acquired images of unusual structures on the southern edge of the crater. The process by which these structures developed is not fully understood.

The whole of Mars' surface was shaped by liquid water around four billion years ago, say scientists.
Signs of liquid water had been seen on southern Mars, but the latest findings reveal similar signals in craters in the north of the Red Planet.
The team made their discovery by examining data from instruments on board Europe's Mars Express and Nasa's Mars Reconnaissance Orbiter

The international Astronomical Union has approved 6 new names for features on Mars:

The 52-km-wide crater, Avarua, located at Latitude: -35.59, Longitude: 109.57, is named after a town in the Cook Islands.

The 42-km-wide crater, Dowa, located at Latitude: -31.38, Longitude: 110.14, is named after a town in Malawi.

The 38-km-wide crater, Fitzroy, located at Latitude: -35.37, Longitude: 112.0, is named after a town in the Falkland Islands/Islas Malvinas.

The 68-km-wide crater, Greg, located at Latitude: -38.29, Longitude: 112.81, is named after the writer Percy Greg (1836-1889).

The 79-km-wide crater, Pl, located at Latitude: -31.02, Longitude: 108.6, is named after the film producer George Pl (1908-1980).

Astronaut's eye view: Mars Express orbiting the Red Planet

Last month, mission controllers commanded the Visual Monitoring Camera (VMC) to acquire an image of Mars every minute during one complete, 7-hour orbit. The VMC is a low-resolution, non-scientific digital camera originally used only to confirm separation of the Mars Express lander in 2003.
The resulting still images have been combined to create a unique video as Mars Express loops between its greatest height above the surface, 10 527 km, to its lowest, at just 358 km, and back again. This is the first such video ever generated from a spacecraft orbiting Mars.

The International Astronomical Union (IAU) has approved the name Oyama for a Martian crater.

Oyama is a 106.8-km wide crater located at 23.66 N, 20.17 W.
The crater was named after Vance I. Oyama, (1922-1998), a biochemist who designed the gas exchange experiment aboard the Viking Mars landers.
