Abstract Electrostatic charging of the GIOTTO spacecraft in different impact induced charged particle environments was studied with 3D numerical particle-in-cell models. The simulation results are assessed according to first experimental results of GIOTTO and VEGA instruments. Decreasing and even negative spacecraft potentials measured on VEGA near closest approach to the comet suggest the influence of the cometary plasma, which is also confirmed by corresponding numerical simulations.
