Phobos flyby images
 
15 March 2010
Images from the recent flyby of Phobos, on 7 March 2010, are released today. The images show Mars rocky moon in exquisite detail, with a resolution of just 4.4 metres per pixel. They show the proposed landing sites for the forthcoming Phobos-Grunt mission.

Volcanic ash in Meridiani Planum

12 May 2010
Deposits of volcanic ash colour this view of the Meridiani Planum, as seen by the Mars Express High Resolution Stereo Camera. They also give clues to the prevailing wind direction in this region of Mars.

An Astronaut's-Eye View of Mars
Jun. 2, 2010 | 08:22 PDT | 15:22 UTC

In a spectacular video released to the Web on the seventh launch anniversary of Mars Express, the "Mars Webcam" has captured an astronaut's eye view of one complete orbit around the Red Planet. Volcanoes, canyons, polar caps, and one of Mars' moons march through the view as the spacecraft sweeps its elliptical path in space around Mars.

Someone is wrong on the Internet.

Wet era on early Mars was global

25 June 2010
Conditions favourable to life may once have existed all over Mars. Detailed studies of minerals found inside craters show that liquid water was widespread, not only in the southern highlands, but also beneath the northern plains.

Rocky mounds and a plateau on Mars

28 June 2010
When Mars Express set sail for the crater named after Portuguese navigator Ferdinand Magellan, it found a windblown plateau and mysterious rocky mounds nearby.

Mars's mysterious elongated crater

27 August 2010
Orcus Patera is an enigmatic elliptical depression near Mars equator, in the eastern hemisphere of the planet. Located between the volcanoes of Elysium Mons and Olympus Mons, its formation remains a mystery.

Melas Chasma on Mars: as low as one can go

8 October 2010

There are few places on Mars lower than this. The floor of Melas Chasma sinks nine kilometres below the surrounding plains. New images from the German Aerospace Centre (Deutsche Zentrum für Luft- und Raumfahrt; DLR) operated High Resolution Stereo Camera on ESA's Mars Express orbiter highlight the complex history of this enormous martian canyon.

Light and dark in the Phoenix Lake


12 November 2010
They say you can't judge a book by its cover but, with planets, first impressions do count. New images show where complex fault lines in Mars Phoenicis Lacus region have resulted in terrain with a distinctly contrasting appearance.

Wind and water have shaped Schiaparelli on Mars

10 December 2010
The small crater embedded in the northwestern rim of the Schiaparelli impact basin features prominently in this new image from ESA’s Mars Express. All around is evidence for past water and the great martian winds that periodically blow.

Mars Express puts craters on a pedestal

4 February 2011
ESA's Mars Express has returned new views of pedestal craters in the Red Planet's eastern Arabia Terra.

The scars of impacts on Mars

4 March 2011
ESA's Mars Express has returned new images of an elongated impact crater in the southern hemisphere of Mars. Located just south of the Huygens basin, it could have been carved out by a train of projectiles striking the planet at a shallow angle.

Neighbouring volcanoes on Mars

1 April 2011

ESA’s Mars Express has returned images of mist-capped volcanoes located in the northern hemisphere of the red planet. Long after volcanic activity ceased, the area was transformed by meteor impacts that deposited ejected material over the lower flanks of the volcanoes.

Mars Express sees deep fractures on Mars
 
6 May 2011

Newly released images from ESA’s Mars Express show Nili Fossae, a system of deep fractures around the giant Isidis impact basin. Some of these incisions into the martian crust are up to 500 m deep and probably formed at the same time as the basin.

Springtime at Mars’ south pole
 
7 June 2011

ESA’s Mars Express celebrates eight years in space with a new view of ice in the southern polar region of Mars. The poles are closely linked to the planet’s climate and constantly change with the seasons. Their study is an important scientific objective of the mission.

Phobos slips past Jupiter

17 June 2011

Earlier this month, ESA’s Mars Express performed a special manoeuvre to observe an unusual alignment of Jupiter and the martian moon Phobos. The impressive images have now been processed into a movie of this rare event.

Mars’ northern polar regions in transition

5 August 2011

A newly released image from ESA’s Mars Express shows the north pole of Mars during the red planet’s summer solstice. All the carbon dioxide ice has gone, leaving just a bright cap of water ice.
 
This image was captured by the orbiter’s High-Resolution Stereo Camera on 17 May 2010 and shows part of the northern polar region of Mars during the summer solstice. The solstice is the longest day and the beginning of the summer for the planet’s northern hemisphere.

The ice shield is covered by frozen water and carbon dioxide ice in winter and spring but by this point in the martian year all of the carbon dioxide ice has warmed and evaporated into the planet’s atmosphere.

Only water ice is left behind, which shows up as bright white areas in this picture. From these layers, large bursts of water vapour are occasionally released into the atmosphere.

The polar ice follows the seasons. In winter, part of the atmosphere recondenses as frost and snow on the northern cap. These seasonal deposits can extend as far south as 45°N latitude and be up to a metre thick.

Rare martian lake delta spotted by Mars Express

2 September 2011

ESA’s Mars Express has spotted a rare case of a crater once filled by a lake, revealed by the presence of a delta. The delta is an ancient fan-shaped deposit of dark sediments, laid down in water. It is a reminder of Mars’ past, wetter climate.

The delta is in the Eberswalde crater, in the southern highlands of Mars. The 65 km-diameter crater is visible as a semi-circle on the right of the image and was formed more than 3.7 billion years ago when an asteroid hit the planet.

Mars Express observes clusters of recent craters in Ares Vallis

7 October 2011

Newly released images taken by ESA’s Mars Express show an unusual accumulation of young craters in the large outflow channel called Ares Vallis. Older craters have been reduced to ghostly outlines by the scouring effects of ancient water.
 
In the distant past, probably over 3.8 billion years ago, large volumes of water must have rushed through the Ares Vallis with considerable force. Mars Express imaged the preserved aftermath of this scene on 11 May 2011.

European orbiter discovers water supersaturation in the Martian atmosphere

6 Oct 2011

New analysis of data sent back by the SPICAM spectrometer on board the Mars Express spacecraft has revealed for the first time that the planet's atmosphere is supersaturated with water vapour. This surprising discovery has major implications for understanding the Martian water cycle and the historical evolution of the atmosphere.
