Hakan Svedhem Biography

ESA's Venus Express launches to begin Europe's first dedicated mission to Venus.

Venus Express enters orbit around Venus and begins preparations for a long-term atmospheric and plasma investigation.

Venus Express observations show a highly variable atmosphere with rapidly changing cloud structures and upper-atmospheric behaviour.

Venus Express measurements help quantify the escape of charged particles from the Venusian atmosphere into space.

Venus Express records large changes in sulfur dioxide abundance that are investigated as possible evidence of recent volcanic activity.

Venus Express surface measurements indicate that the planet's rotation is slightly slower than values derived from Magellan observations.

Venus Express performs experimental aerobraking passes through the upper atmosphere near the end of its mission.

ESA ends Venus Express operations after fuel depletion following more than eight years of observations around Venus.
