Abstract: [1] Stardust successfully encountered comet 81P/Wild 2 on 2 January 2004 at a distance of 236.4 ± 1 km. All encounter investigations acquired valuable new and surprising findings. The time-of-flight spectrometer registered 29 spectra during flyby and measured the first negative ion mass spectra of cometary particles. The dust detectors recorded particles over a broad mass range, 10 À11 to 10 À4 g. Unexpectedly, the dust distribution along Stardust's flight path was far from uniform, but instead occurred in sh…
