The HRSC camera on board the Mars Express acquired this image of the Martian horizon primarily because it provides a clear view of the atmospheric structure enveloping the planet. A clear separation between the lower, denser atmosphere and the stratosphere is visible.

The High Resolution Stereo Camera (HRSC) on board ESA's Mars Express orbiter has been delivering high-resolution images from the surface of Mars since January 2004 – in colour and 3-D. A monthly selection of these images is published on the dedicated page that covers the Mars Express mission. Quite often, we receive questions about these images and the geological peculiarities they reveal. Other questions are simply about Mars in general.

Mission HI-SEAS: 'Life on Mars'

Lucie Poulet said goodbye to the outside world for four months; the scientist from the German Aerospace Center DLR is a crewmember in the Mars simulation run by the University of Hawaii at Manoa. Among other things, the 28-year-old scientist will use the second mission within the Hawaii Space Exploration Analogue and Simulation (HI-SEAS) programme to study the influence that light of different wavelengths has on plants. But she will also be the subject of intense observation – the University of Hawaii is using the habitat to examine how the six participants behave and work together during the months of isolation. In this blog she tells about her ‘life on Mars’. read more
