At this point the spacecraft was running on an ellipse substantially closer to the planet than during the initial orbit.
Seven further orbit control maneuvers, two with the main engine and five with the thrusters, were required for Venus Express to reach its final operational 24-hour orbit around Venus.Venus Express entered its target orbit at apoapsis on at UTC, when the spacecraft was 151,000,000 kilometres (94,000,000 mi) from Earth.The periapsis was located almost above the North pole (80° North latitude), and it took 24 hours for the spacecraft to travel around the planet.Venus Express studied the Venusian atmosphere and clouds in detail, the plasma environment and the surface characteristics of Venus from orbit.Venus Express (VEX) was the first Venus exploration mission of the European Space Agency (ESA).
Launched in November 2005, it arrived at Venus in April 2006 and began continuously sending back science data from its polar orbit around Venus.
It operates in the visible, ultraviolet, and near infrared spectral ranges, and maps surface brightness distribution searching for volcanic activity, monitoring airglow, studying the distribution of unknown ultraviolet absorbing phenomenon at the cloud-tops, and making other science observations.
It is derived in part by the Mars Express High Resolution Stereo Camera (HRSC) and the Rosetta Optical, Spectroscopic and Infrared Remote Imaging System (OSIRIS).
On 28 November 2014, mission control lost contact with Venus Express.
Intermittent contact was reestablished on 3 December 2014, though there was no control over the spacecraft, likely due to exhaustion of propellant.
It was hoped that The mission was proposed in 2001 to reuse the design of the Mars Express mission.
