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
