TL;DR: A review of the development of dust science from the first ground-based astronomical observations of dust in space to compositional analysis of individual dust particles and their source objects can be found in this article.

TL;DR: Grun et al. as mentioned in this paper published and analyzed the complete dataset of 509 recorded impacts of dust particles with masses between 10−16 g −10−7 g. The observed impact rate is compared with a model for the flux of interstellar dust particles which gives relatively good agreement with the observed impact ratio.

Abstract: The objective of this paper is to illustrate the influence of the radiation pressure and the electromagnetic force on dust particles in interplanetary space. Between 1990 and 2001 62 so-called β-meteoroids (β describes the ratio of the radiation pressure force to gravity) were detected as dust particles coming from the inner solar system on hyperbolic orbits. 24 of them were detected shortly after the launch of Ulysses within the ecliptic and 38 of them were recorded primarily passing the Solar poles. Furthermore high speed particles not coming from the direction of the Sun were ejected from the solar system by electromagnetic forces. For the time period until the end of 2008 the effective area for particles coming from the direction of the Sun has been determined. The particles' perihelion distances indicated that they originated within a region of 0.5 AU from the Sun. For the second orbit of Ulysses the flux of β-meteoroids was determined using the same method as during its first revolution. Because of the more defocusing phase during the first orbit of Ulysses the production rate of β-meteoroids has been estimated to be nearly twice of that for the second revolution. On the other hand, an imbalance of the identified β-meteoroids between the north and south pole could not be explained by the solar cycle.

TL;DR: The Triple F ( Fresh From the Fridge) mission as mentioned in this paper was proposed to extract three sample cores of the upper 50 cm from three locations on a cometary nucleus and return them cooled to Earth for analysis in the laboratory.

TL;DR: In this article, the authors used two up-to-date computer models, the ESA Interplanetary Meteoroid Engineering Model (IMEM, Dikarev et al., 2005a, c), and the interstellar dust module of the Interplanned Meteoroid environment for EXploration model (IMEX), to study the detection conditions and fluences of interplanetary and interstellar dust with DDA.
