Instruments

Giotto carried ten scientific instruments. They included:

  • a narrow-angle, multicolour camera to obtain pictures of the nucleus
  • three mass spectrometers to measure gas and dust composition
  • a dust impact detector to measure the mass of dust particles striking the shield
  • two plasma experiments to study the solar wind and charged particles
  • an energetic particles analyser to study electrons, protons and alpha-particles
  • a magnetometer to study changes in the magnetic field
  • an optical probe to study brightness of the coma
  • a radio science experiment to investigate the electron environment was also carried out by comparing signals sent at different frequencies from the spacecraft
