Study atmosphere, plasma environment and surface of Venus
The Venus Express payload comprises a combination of spectrometers, spectro-imagers and imagers covering a wavelength range from ultraviolet to thermal infrared, a plasma analyser and a magnetometer. This set of instruments is able to study the atmosphere, plasma environment and surface of Venus in great detail.
The investigation aims to enhance our knowledge of the composition, circulation and evolution of the atmosphere of Venus. The surface properties of Venus and the interaction between the atmosphere and the surface are examined and evidence of volcanic activity is sought.
Measurement instruments on Venus Express
Most of the instruments are re-using designs and/or spare hardware originating from either Mars Express or Rosetta and have been fitted onto a spacecraft whose design is derived from Mars Express and adapted to cope with the thermal and radiation environment in Venus orbit.
The instruments were provided by collaborative efforts between scientific institutes in ESA member states and Russia. Principal investigators in different European countries lead the nationally funded collaborations.
