New global maps of Mars released on the 10th anniversary of the launch of ESA's Mars Express trace the history of water and volcanic activity on the Red Planet, and identify sites of special interest for the next generation of Mars explorers.

High above the main body of Mars' atmosphere is a region of weakly ionised gas, known as the ionosphere. New studies, based on observations from Mars Express, show that the dayside ionosphere is more variable and more complex than previously thought.

Despite more than a century of observations, the orbit of the Martian moon Deimos is still not known to a high degree of accuracy, but a new study using images taken by ESA's Mars Express orbiter has provided the best orbital model to date.

Scientists have probed the Sun's corona via the disturbances it causes to radio transmissions from Mars Express, Venus Express and Rosetta. This technique has allowed the detection of coronal mass ejections and revealed the morphology of these colossal solar eruptions in great detail.

A new study of the ancient, cratered highlands of Mars has detected numerous exposures of minerals that were altered by underground water during the planet's early history.

The first targeted, high resolution measurements of Martian gravity have enabled scientists to probe deep beneath the surface of Mars and provide new insights into the formation of the planet's massive volcanoes.

A faint, infrared glow above the winter poles of Mars is giving new insights into seasonal changes in the planet's atmospheric circulation. The tell-tale night emission was detected with the Mars Express OMEGA imaging spectrometer.

Following an anomaly affecting its on-board mass memory, a work-around that changes the way commands are stored and executed by the spacecraft is complete, allowing resumption of full science operations.

The MARSIS radar instrument on board ESA's Mars Express orbiter has discovered a subsurface blanket of low density material around the north polar cap.

The Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) has recently completed a subsurface sounding campaign over the planet's North Pole.

Operational anomalies in the memory system on board Mars Express have caused science observations to be temporarily halted. Both a work-around to enable the resumption of a number of observations and a long-term solution are being investigated.
Published: 31 October 2011
New analysis of data sent back by the SPICAM spectrometer on board ESA's Mars Express spacecraft has revealed for the first time that the planet's atmosphere is supersaturated with water vapour.
Published: 29 September 2011
Detailed studies of hydrated minerals found inside impact craters show that liquid water was widespread not only in the southern highlands, but also beneath the planet's northern plains, confirming that conditions favourable to life once existed all over Mars.

Images from the recent flyby of Phobos, on 7 March 2010, show Mars' rocky moon in exquisite detail, with a resolution of just 4.4 metres per pixel.

On 3 March 2010 Mars Express will make its closest ever approach to Phobos. The close approach provides a first opportunity to perform a unique gravity experiment that may reveal the distribution of mass within this intriguing moon.

New measurements of ozone in the atmosphere of Mars are being obtained in a coordinated observation campaign with Mars Express and a Hawaiian-based telescope

The MARSIS radar sounder instrument on board Mars Express, designed to study the ionosphere, surface and sub-surface of Mars, can unexpectedly also double as a magnetometer

To reconcile measured methane enhancements and variations on Mars with the current global chemical-
climate model, both a strong local source and an as yet unidentified and very effective methane destruction mechanism are required, a recent study finds

From 20 - 24 July an ESA-sponsored Mars Advanced School will be held in Jiaxing, Zhejiang Province, China. About 40 graduate and postdoctoral students, as well as researchers, from mainland China and Taiwan, will attend this intensive, five-day course, with expert teaching staff from Europe and China.

Observations made with the OMEGA imaging spectrometer onboard Mars Express reveal very strong signatures of sulfates and ferric oxides in Aram Chaos. The presence of these chemicals may indicate that significant amounts of water were present in this area in the past.
