Collisions with cometary dust recorded by the Giotto HMC camera.

Keller, H. U.; Curdt, W.

The authors concentrate on the detailed directional information provided by the Halley Multicolour Camera (HMC) as a result of its excellent resolution and the high attitude stability of the Giotto spacecraft. This information was used to determine the trajectory and to identify attitude excursions caused by discrete dust impacts on the space prob…

The Giotto experiments

Reinhard, R.

Design and performance features of the scientific instruments carried on the Giotto spacecraft are described. The instruments were selected to meet the basic mission goals: characterize the elemental and isotopic composition of volatile components of the cometary coma and the physical processes and chemical reactions in the cometary atmosphere and…

The Giotto encounter with Halley's Comet - First scientific results

Reinhard, R.

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…
