The Giotto spacecraft passed within 600 km of the Comet Halley nucleus on the sunward side. Dust jets which form spirals around it while the nucleus rotates once every 52-53 hr caused the collision of large dust particles with Giotto starting 15 sec from closest encounter. A nutation induced on the spacecraft by the impacts were damped by on-board systems while sensors continued to record data. Several on-board instruments were badly damaged. The imagery obtained, however, revealed a single nonspherical potato-shaped nucleus about 15 km long and 7-10 km in average diameter. The surface had an albedo of 0.02-0.04 and featured two large dust jets. Spectrometer data confirmed that water vapor is the dominant parent molecule in the coma, and that the majority ionized water ions near the nucleus were joined by carbon, oxygen, sodium, sulfur and iron. The various other molecules and atoms observed near the nucleus, in the coincident solar wind plasma and in the cometary bow shock are delineated. The magnetic field reached a maximum of 57 nT and decreased to zero 4700 km from the nucleus.
