Gullies-ESP_020661_1440-PCF-LXTT-IPF.jpgGullies in Gasa Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)78 visiteThe so-called "Gully Landforms" - just like the ones shown here, in this NASA - Mars Reconnaissance Orbiter image - can often be found in the Inner Rims (or even below, along the Inner Slopes) of many Impact Craters that are located at the Martian Mid-Latitudes. Some changes in these Gully Landforms were first seen in frames taken by the NASA - Mars Global Surveyor - Mars Orbiter Camera (MGS-MOC) in the AD 2006, and studying such activity has been a high priority for HiRISE ever since (and, in fact, many examples of New Deposits located inside Gully Landforms are now well known).
This frame shows a New Deposit inside some Gully Landforms located on the Inner Rim of Gasa Crater; a very (relatively speaking) "fresh" approx. 7-Km diameter Impact Crater that is found in the Southern Mid-Latitudes of the Red Planet (to be precise, at 35,72° South Latitude and 129.45° East Longitude). Said New Deposit appears of a distinctive gray color, with some patches of white Material too, in this Absolute Natural Color version of the NASA - Mars Reconnaissance Orbiter image n. ESP_020661_1440. The picture was acquired during the Southern Spring of Mars, but the Flow that formed the Deposit occurred in the preceding Winter.
As a matter of fact, the current Gully Activities appear to be concentrated in periods going from the late Winter to the early Spring of Mars, and this circumstance may be a consequence of the Sublimation of the Seasonal Carbon Dioxide (CO2) Frost (which, by the way, is well visible in several Gully "Alcoves" during Wintertime).
Mars Local Time: 15:49 (Middle Afternoon)

Spacecraft altitude: 258,2 Km (such as about 160,3 miles)
Original image scale range: 25,8 cm/pixel (with 1 x 1 binning) so objects ~ 78 cm across are resolved
Map projected scale: 25 cm/pixel
Map projection: EQUIRECTANGULAR
Emission Angle: 11,0°
Sun-Mars-Spacecraft (or Phase) Angle: 47,6°
Solar Incidence Angle: 58° (meaning that the Sun was about 32° above the Local Horizon at the time the picture was taken)

This picture (which is an Original Mars Reconnaissance Orbiter EDM enhanced color frame, identified by the serial n. ESP_020661_1440) has been additionally processed and then re-colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Reconnaissance Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.MareKromium

Fienga - Lunexit Team)111 visiteThe Landforms visible in this observation are quite diverse, with a segment of the Cerberus Fossae (such as a deep Trough extending East-West) and Surrounding Terrain that has been eroded by some Fluid, either Water (actually Mud) or Lava. There are also many Boulders in places, either on steep Slopes or excavated by Impact Craters. The high Hills are Islands of older Terrain surrounded by younger Lavas.

ESP_027378_2540-PCF-LXTT-IPF-2.jpgNorthern Dunes (EDM - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunexit Team)84 visiteThe Dunes visible in this EDM are approximately 100 meters across and they are traversing a bumpy, hard Terrain. Polygonal Patterns are evident in some areas while numerous meter-scale Boulders are strewn throughout the whole Region. The Boulders are more numerous in areas where the Polygonal Patterns are less pronounced. Repeated imaging of this large Dunefield shall reveal whether these Dunes are presently moving (so-called "Migrating Dunes") or not.
