TL;DR: Data at large masses recently analysed from the DIDSY data set show clear evidence of a decrease in the mass distribution index at these masses within the coma, and it is shown that such a value of the mass index can provide sufficient mass for consistency with the observed deceleration.
Journal ArticleDOI

TL;DR: In this paper, the density and the mass spectrum of the dust near comet Halley have been measured by the Giotto space probe's dust impact detection system, showing depletion in small and intermediate masses; at about 600 km from the nucleus, however, the dust activity rises and the spectrum is dominated by larger masses.
Journal ArticleDOI

TL;DR: In the European Space Agency's 1992 Giotto Extended Mission, the Dust Impact Detection System operated successfully during a fly-by that took the spacecraft within about 200 km of the nucleus of comet Grigg-Skjellerup as discussed by the authors.
Journal ArticleDOI
Impacts on Hubble Space Telescope solar arrays: Discrimination between natural and man-made particles
TL;DR: A post-flight investigation was initiated by the European Space Agency to analyze impacts on solar arrays of the Hubble Space Telescope (HST), exposed to space for 8.25 years at approximately 600 km altitude as mentioned in this paper.
Journal ArticleDOI
Hypervelocity impacts on HST solar arrays and the debris and meteoroids population
TL;DR: A post-flight impact investigation was initiated by the European Space Agency to record and analyse the impact fluxes and any potential resulting damage on the two flexible solar arrays of the Hubble Space Telescope as discussed by the authors.
