modest ‘webcam’ on Mars Express has proven useful for outreach, education and citizen-science. Now ESA have decided to adopt it as a professional science instrument.

Mars Express was launched in 2003 with a simple, low-resolution camera to provide visual confirmation that its Beagle 2 lander had separated. Once that was done, the camera was switched off, and the craft got on with its main mission using its ‘real’ scientific instruments .

info on the winners.

Their prize is an expenses-paid visit to ESA’s control centre in Darmstadt, Germany, to meet Mars Express flight controllers as well as the centre’s Advanced Mission Concepts Section, who helped to prepare this ‘open data’ contest.
“In our day-to-day work we typically analyse data connected to various real-world topics such as medicine, ecology or finance,” explains the institute’s Bernard Ženko.

Scattered pockets of magnetism across the surface of Mars have a significant influence on the planet's upper atmosphere, according to observations from ESA's Mars Express. Understanding these effects may be crucial for ensuring safe radio communications between Mars and Earth and, eventually, between explorers on the surface of the planet.

As the energetic particles of the solar wind speed across interplanetary space, their motion is modified by objects in their path. A study, based on data from ESA's Mars Express orbiter, has thrown new light on a surprising interaction between the planet Mars and supersonic particles in the solar wind.

Every so often, your smartphone or tablet receives new software to improve its functionality and extend its life. Now, ESA’s Mars Express is getting a fresh install, delivered across over 150 million km of space.
With nearly 15 years in orbit, Mars Express – one of the most successful interplanetary missions ever – is on track to keep gathering critical science data for many more years thanks to a fresh software installation developed by the mission teams at ESA.
The new software is designed to fix a problem that anyone still using a five-year-old laptop knows well: after years of intense usage, some components simply start to wear out.

New research using a decade of data from ESA’s Mars Express has found clear signs of the complex martian atmosphere acting as a single, interconnected system, with processes occurring at low and mid levels significantly affecting those seen higher up.
Understanding the martian atmosphere is a key topic in planetary science, from its current status to its past history. Mars’ atmosphere continuously leaks out to space, and is a crucial factor in the planet’s past, present, and future habitability – or lack of it. The planet has lost the majority of its once much denser and wetter atmosphere, causing it to evolve into the dry, arid world we see today.
However, the tenuous atmosphere Mars has retained remains complex, and scientists are working to understand if and how the processes within it are connected over space and time.

Radar data collected by ESA’s Mars Express point to a pond of liquid water buried under layers of ice and dust in the south polar region of Mars.
Evidence for the Red Planet’s watery past is prevalent across its surface in the form of vast dried-out river valley networks and gigantic outflow channels clearly imaged by orbiting spacecraft. Orbiters, together with landers and rovers exploring the martian surface, also discovered minerals that can only form in the presence of liquid water.

Description
ESA’s Mars Express radar team recently made an exciting announcement: data from their instrument points to a pond of liquid water buried about 1.5 km below the icy south polar ice of Mars.

This image shows what appears to be a large patch of fresh, untrodden snow – a dream for any lover of the holiday season. However, it’s a little too distant for a last-minute winter getaway: this feature, known as Korolev crater, is found on Mars, and is shown here in beautiful detail as seen by Mars Express.
ESA’s Mars Express mission launched on 2 June 2003, and reached Mars six months later. The satellite fired its main engine and entered orbit around the Red Planet on 25 December, making this month the 15-year anniversary of the spacecraft’s orbit insertion and the beginning of its science programme.

Mars Express has revealed the first geological evidence of a system of ancient interconnected lakes that once lay deep beneath the Red Planet’s surface, five of which may contain minerals crucial to life.

Is it only me or does anyone else find this color-scheme "wrong"...

The background image is shown in colours representing topography: reds and oranges are lower elevations, and blues and greens are higher ones.

I usually would choose reds as higher elevations & blues and greens for lower ones.
Like https://www.google.com/mars/ for example.

Yes - but since they looked for lower altitudes rather than higher altitudes...

Do we know how recent those big craters were made ?

Depends on what you call recent. Those must be at least noachian, some are in early noachian highlands, so those could be about 4.5-3.7 billion years old.

A reanalysis of data collected by ESA’s Mars Express during the first 20 months of NASA’s Curiosity mission found one case of correlated methane detection, the first time an in-situ measurement has been independently confirmed from orbit.
Reports of methane in the martian atmosphere have been intensely debated, with Mars Express contributing one of the first measurements from orbit in 2004, shortly after its arrival at the Red Planet.
