“…Further confirmation that the majority of dust impacts in LEO occurs in clusters, some of which representing circumterrestrial streams, has since been given by the dust-counter-type instruments SPADUS (Tuzzolino et al, 2005), DEBIE-1 & 2 (Schwanethal et al, 2005;Menicucci et al, 2013), and SODAD-1 & 2 (Durin and Mandeville, 2009;Durin et al, 2016Durin et al, , 2022. One of the streams detected by SPADUS could be attributed to a known SRM firing (Neish et al, 2004;Bunte and Drolshagen, 2005), whereas another one appeared to be associated with the explosion of a launch vehicle upper stage (Tuzzolino et al, 2001).…”

Early-generation in situ dust detectors in near-Earth space have reported the occurrence of clusters of sub-micron dust particles that seemed unrelated to human spaceflight activities. In particular, data from the impact ionization detector onboard the HEOS-2 satellite indicate that such swarms of particles occur throughout the Earth’s magnetosphere up to altitudes of 60 000 km—far beyond regions typically used by spacecraft. Further account of high-altitude clusters has since been given by the GEO-deployed GORID detector, however, explanations for the latter have so far only been sought in GEO spaceflight activity. This perspective piece reviews dust cluster detections in near-Earth space, emphasizing the natural swarm creation mechanism conjectured to explain the HEOS-2 data—i.e. the electrostatic disruption of meteoroids. Highlighting this mechanism offers a novel viewpoint on more recent near-Earth dust measurements. We further show that the impact clusters observed by both HEOS-2 and GORID are correlated with increased geomagnetic activity. This consistent correlation supports the notion that both sets of observations stem from the same underlying phenomenon and aligns with the hypothesis of the electrostatic breakup origin. We conclude that the nature of these peculiar swarms remains highly uncertain, advocating for their concerted investigation by forthcoming dust science endeavours, such as the JAXA/DLR DESTINY + mission. This article is part of the theme issue ‘Dust in the Solar System and beyond’.
