TL;DR: In this paper, the impact ionization detector was used for the first time to detect the impact of an iron projectile in the mass range 10−15 to 10−9 g and in the speed range 1 km/s to 70 km /s.

TL;DR: More than 80 and 40 different spokes have been measured at the morning and at the evening ansa, respectively, and the age distribution (i.e., time from radial formation until observation, assuming Keplerian shear) of the leading (old) edges of spokes has its maximum at approximately 9,000 s as mentioned in this paper.

TL;DR: In this article, a special experimental set-up for substrate preparation, dust collection and secondary ion mass spectroscopy (SIMS) analysis of dust under ultrahigh vacuum conditions was developed.

TL;DR: An excellent review of the present understanding of the structure and formation of Jupiter's rings has recently been published by Burns et al. as mentioned in this paper, who summarized the basic ideas and open questions concerning the physical phenomena governing Jupiter's ring.
