Mars Express: From worry to water
In 2004, a year after Europe’s first mission to Mars was launched, the flight dynamics team at ESA’s operations centre encountered a serious problem. New computer models showed a worrying fate for the Mars Express spacecraft if mission controllers continued … Continue reading

Mars Express radar finds liquid water under Mars south polar region
Editor’s note: NASA has commented on this discovery. 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. [The researchers’ paper reporting … Continue reading

Radar shows Mars atmosphere behaves as a single system
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. … Continue reading

Mars Express: Radar echoes from Meridiani Planum
Searching for signs of ice on Mars is complex. To explore whether ice lurks beneath the surface of the Red Planet, ESA’s Mars Express uses its radar to probe the interior. It sends low-frequency radio pulses at Mars and records … Continue reading

Radar shows thick, porous sediments & no ground ice under Meridiani Planum
New findings reveal deposits on Mars that could be interpreted to be ice-rich may contain little or no ice at all, based on an analysis of radar sounder data for Meridiani Planum — an area on the planet’s equator being … Continue reading

Mars ionosphere shaped by crustal magnetic fields
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 … Continue reading
Comet Siding Spring’s effects on Mars atmosphere
Two NASA and one European spacecraft that obtained the first up-close observations of a comet flyby of Mars on Oct. 19, have gathered new information about the basic properties of the comet’s nucleus and directly detected the effects on the … Continue reading

Radar measures thickness of Meridiani Planum sedimentary units
Landed upon and explored by the Opportunity rover, the rocks of Meridiani Planum have been intensively studied, both from orbit and from ground level. Now scientists in a team led by Thomas Watters (Smithsonian Institution) have used the MARSIS ground-penetrating … Continue reading

Hidden valley at the north pole
The north polar cap of Mars has a wide, deep trough called Chasma Boreale that slices into the polar cap for 560 kilometers (350 miles). The floor of the chasma exposes a layer of sand and dust cemented with water … Continue reading
