| | Giotto |
 | | Giotto is a dual spin configuration spacecraft with the main spacecraft structure spinning, and carrying all the subsystem equipment and the experiments, and the large paraboloid reflector of the high-gain antenna, the beam of which is inclined 44.3° with respect to the spacecraft's spin axis, kept pointing towards Earth. |
 | | The ionopause was crossed on the inward-bound leg of the journey by Giotto at a distance of 4650 kilometers (2,890 miles), and during the outward bound leg at a distance of 3,940 kilometers (2,450 miles) from the nucleus. |
 | | Giotto's payload had been switched on during the evening of 9 July, with eight of the original complement of 11 experiments still operable: namely the magnetometer, Johnstone plasma analyzer, energetic-particle analyzer, optical-probe experiment, Reme plasma analyzer, dust impact detection system, ion mass-spectrometer, and the radio-science experiment. |
