Data from the Visual Monitoring Camera (VMC) instrument onboard ESA's Mars Express is now available in the Planetary Science Archives (PSA). The data come from observations taken of Mars between 2007 to mid-2020, as well as of the release of the Beagle 2 lander in 2003, and are calibrated for scientific use.

In past decades, spacecraft have sent back huge amounts of complex data about Mars, providing a wealth of information about the planet. More than ever, the scientific community needs a way to sift through, compare, and analyse these data, prompting the development of two new tools for exploring the surface of the Red 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.

A recent study from ESA's Mars Express and NASA's Mars Reconnaissance Orbiter (MRO) provides new evidence for a warm young Mars that hosted water across a geologically long timescale, rather than in short episodic bursts – something that has important consequences for habitability and the possibility of past life on the planet.

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.

There is a wealth of evidence, collected over the past few decades, that suggests liquid water was abundant in the early history of Mars – one of our nearest and most studied neighbours. A recent study, using data from several spacecraft operating at Mars, paints a detailed picture of the rise and fall of standing bodies of water in a region of...
