Hellas_Planitia-H0572_0000_ND2_H-PCF-LXTT.jpgFrame H0572_0000_ND2: Hellas Planitia Region220 visiteCaption ESA:"The HRSC on board ESA's Mars Express Spacecraft obtained this image on July, 1st, 2004 during orbit 572 with a ground resolution of approx. 45,1 mt per pixel.
The scene shows a portion of Hellas Planitia, a Region which is about 234 Km wide in the North, 345 Km in the South, about 898 Km in length, and centred at approx. 89 East Long. and 29 South Lat.
This image represents an area on the Northern Eastern Rim of Hellas Planitia, also known as the Hellas Impact Basin in Mars's Southern Hemispere. The Basin is thought to have formed around 3900 Million Years ago in a single massive impact".MareKromium

Phobos-400-455-20091201.jpgBig Brother and Little Brother70 visitePhobos and Deimos RAW (left panel) and processed images (right panel).
In a first, ESAs 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

Echus_Chasma-398-260508-2204-6-co-01-H2.jpgHigh Cliffs Surrounding Echus Chasma on Mars76 visiteWhat created this great cliff on Mars? Did giant waterfalls once plummet through its grooves? With a four-kilometer drop, this high cliff surrounding Echus Chasma, near an impressive impact crater, was carved by either water or lava. A leading hypothesis is that Echus Chasma, at 100-Km long and 10-Km wide, was once one of the largest water sources on Mars. If true, water once held in Echus Chasma likely ran over the Martian Surface to carve the impressive Kasei Valles, which extends over 3000 Km to the North. Even if initially carved by water, lava appears to have later flowed in the valley, leaving an extraordinarily smooth floor. Echus Chasma lies north of tremendous Valles Marineris, the largest canyon in the Solar System. The above image was taken by the robotic Mars Express spacecraft currently orbiting Mars.

NepenthesMensae-385-090408-5212-6-co1-01.jpgNepenthes Mensae (MULTISPECTRUM; credits: Lunexit)111 visiteThe High Resolution Stereo Camera on board ESAs Mars Express Orbiter imaged Nepenthes Mensae, a river delta on Mars, on 22 January 2008.
The data was acquired in the Region lying at approx. 3 North and 121 East, with a ground resolution of 15 mt/pixel.
The southern part of the image shows a structure reminiscent of a river delta on Earth, whose material was eroded from a valley, about 30 Km long and upto 1000 mt deep. This formed a fan-shaped deposit at the mouth of the valley. The rim of the deposit stands roughly 300 mt above the floor of the depression.
The resemblance of the structure to river deltas on Earth suggests that it was formed by a similar mechanism. Scientists believe that sediment transported by water was deposited as the flow of the water slowed down where the channel widened and met the mouth of the river.
The pictures show that the Region was affected by two episodes of flooding.
The first left a cone-shaped deposit, reaching far out into the lowland.
The second episode formed the fan with the distinct margin. This margin could indicate the location where sediments flowed into a standing body of water or ice.
Numerous hills and flat-topped mountains visible in the central part of the depression are remnants of the material that was present in the area.
The material was then eroded forming the depression, leaving behind the elevations visible today.MareKromium
