Venus Express Mission to Venus

Goals: The European Space Agency's Venus Express was designed to study the atmosphere of Venus, from the surface to the ionosphere. The mission reused the same design as ESA's Mars Express and spare parts from other deep space missions.

Accomplishments: After arriving at Venus in April 2006, Venus Express logged many firsts. One of the most significant findings were signs that Venus had been volcanically active in the last three million years -- suggesting the planet may still be geologically active.

The orbiter also made extensive meteorological maps of Venus, providing measurements of wind fields and temperatures and the chemical composition of the atmosphere. The spacecraft found a striking double-eyed atmospheric vortex that dominates the south pole. It detected water molecules escaping into space, found concrete evidence for lightning in the Venusian atmosphere and provided infrared glimpses of the hot surface.

Venus Express, after running out of propellant, ended its mission in December 2014.

Fast Facts
Venus Express Facts Venus Express returned the clearest indication yet that Venus is still geologically active.

Venus Express is a virtual twin of Mars Express. However, the engineers modified the spacecraft to withstand the harsh environment around Venus (the spacecraft receives four times the amount of solar radiation as Mars Express).

Venus Express is a thrifty mission. To keep costs low, Venus Express also used spare parts from Mars Express and Rosetta.
