description Mars Express Overview

Mars Express is a planetary exploration mission developed by the European Space Agency (ESA), launched in 2003 to study the Martian environment. The mission's primary component is an orbiter that remains operational, utilizing instruments like the High Resolution Stereo Camera to map the planet's surface and geology. It also deployed the Beagle 2 lander, which successfully reached the surface but failed to communicate, while the orbiter continues to analyze atmospheric composition and subsurface water.

help Mars Express FAQ

What space agency launched the Mars Express mission?

Mars Express is the European Space Agency's (ESA) first exploration mission to Mars. It was launched in June 2003 and successfully entered orbit later that year, carrying the ill-fated Beagle 2 lander along with it.

What happened to the Beagle 2 lander carried by Mars Express?

Although Mars Express successfully deployed the Beagle 2 lander toward the Martian surface in 2003, the lander failed to communicate after its scheduled touchdown. It was declared lost, though images later revealed it had successfully landed but failed to fully deploy its solar panels.

What significant scientific discoveries has the Mars Express orbiter made?

The orbiter's MARSIS radar instrument famously confirmed the presence of massive deposits of subsurface water ice on Mars. It also discovered evidence of hydrated minerals and mapped the planet's atmospheric composition and surface geology in high detail.

Is the Mars Express mission still operating?

Yes, Mars Express has vastly exceeded its initial planned lifespan of one Martian year (about 687 Earth days) and remains operational. ESA continues to use the aging spacecraft to relay communications from surface rovers and capture 3D imagery of the Martian terrain.
