Echus_Chasma-398-260508-2204-6-co-01-H1.jpgEchus Chasma (False Colors)65 visiteThe High-Resolution Stereo Camera (HRSC) on board ESA's Mars Express has returned images of Echus Chasma, one of the largest Water Source Regions on the Red Planet.
The data were acquired on September, 25, 2005.
The pictures are centred at about 1° North and 278° East and have a ground resolution of approx. 17 mt/pixel.
Echus Chasma is an approx. 100 Km long and 10 Km wide incision in the Lunae Planum High Plateau North of Valles Marineris, the "Grand Canyon" of Mars. Echus Chasma is the Water Source Region of Kasei Valles, which extends thousands of Km to the North, and its southern-most part. The images of the Echus Chasma plateau show valleys that are about 10 km long and 1000 m deep. The main valley, Kasei Valles, is about 4 km in depth. The smaller valleys, also called sapping canyons, originate from the discharge of groundwater.
Echus Chasma is bounded to the West by the Echus Chasma Plateau, which lies about 4 Km above Echus' floor. MareKromium

SouthPole-MG_SP_Fig02a_H.jpgThe South Pole of Mars (natural colors; credits: Lunexit)65 visiteCaption ESA:"This is a mosaic of images taken by the Mars Express’s Visible and Infrared Mineralogical Mapping Spectrometer, OMEGA.
It shows the Residual South Polar Cap at the end of Northern Winter on the Red Planet. The cap appears clearly asymmetric, its centre being displaced by 3° from the Geographic Pole".MareKromium

Phobos-400-455-20091201.jpgBig Brother and Little Brother65 visitePhobos and Deimos RAW (left panel) and processed images (right panel).
In a first, ESA’s Mars Express Orbiter imaged the Martian Moons Phobos and Deimos together on November, 5th, 2009.
Apart from their ‘wow’ factor, these unique images will help the HRSC team validate and refine existing orbit models of the two moons.
The images were acquired with the Super Resolution Channel (SRC) of the High Resolution Stereo Camera (HRSC). The camera took 130 images of the moons on November 5th at 09:14 CET in a span of 1,5 minutes at intervals of 1", speeding up to 0,5" intervals toward the end. The image resolution is 110 m/pixel for Phobos and 240 m/pixel for Deimos — Deimos was more than twice as far from the camera.
The Super Resolution Channel of the HRSC uses an additional lens, which has a very narrow field of view of just 0,5°, providing four times the magnification than otherwise providing four times the resolution of the HRSC colour stereo channel.
Phobos, the larger of the two moons, orbits closer to the Red Planet, circling it every 7 hours and 39 minutes. It travels faster relative to Mars than the Moon relative to Earth.
Phobos was about 11.800 Km from Mars Express when the images were taken. Deimos, instead, was about 26.200 Km away.MareKromium

PrometheiPlanum.jpgPromethei Terra (Natural Colors + MULTISPECTRUM; credits: ESA & Lunexit)64 visitePromethei Planum, an area seasonally covered with layer of ice more than 3500 mt thick layer of ice in the Martian South Polar Region, was the subject of the High Resolution Stereo Camera’s focus on 22 September 2005 as Mars Express was in orbit above the Red Planet.
Promethei Planum lies at approx. 76° South Lat. and 105° East Long.
An approx. 100 Km-large and 800 mt-deep impact crater is visible in the Northern part of the image. The crater’s interior is partly covered in ice.
In the centre of the image are structures that may have been created by basaltic lava flow from a volcano. This area is covered in ice. The dark dunes towards the bottom of the image are most likely made up of dust originating from this lava flow or volcanic ash.
A broad sheet of ice, which is an extension of the South Polar Ice Cap is located South of the lava flow. The steep flanks clearly show white, clean ice. The thickness of the ice is between 900 and 1100 mt.MareKromium

The image data were acquired from a distance of about 97 Km from Phobos' Surface, with a spatial resolution of about 3,7 mt/pixel, during orbit 5851.
These images have surpassed all previous images from other missions in continuous coverage of the illuminated surface at the highest spatial resolution of 3,7 mt/pixel".
This image has been geometrically corrected and exhibits the original illumination and photometric conditions". MareKromium
