Can you spot a speck of space dust? NASA's Stardust spacecraft has been collecting cosmic dust: Aerogel tiles and aluminum foil sat for nearly 200 days in the interstellar dust stream before returning to Earth. Citizen scientists identified most of the 71 tracks where particles were caught in the aerogel, and scanning electron microscopy revealed 25 craterlike features where particles punched through the foil. By performing trajectory and composition analysis, Westphal et al. report that seven… 
Interstellar dust in the solar system: model versus in situ spacecraft data
Context. In the early 1990s, contemporary interstellar dust penetrating deep into the heliosphere was identified with the in situ dust detector on board the Ulysses spacecraft. Later on, interstellar
Flux and composition of interstellar dust at Saturn from Cassini’s Cosmic Dust Analyzer
The results show that, remarkably, these grains lack carbon-bearing compounds and have been homogenized in the interstellar medium into silicates with iron inclusions, which suggest the presence of magnesium-rich grains of silicate and oxide composition, partly with Iron inclusions.
The Dawn of Dust Astronomy
We review 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. A
Cosmic Dust IX
In the early 1990s, contemporary interstellar dust penetrating deep into the heliosphere was identified with the in situ dust detector on board the Ulysses spacecraft. Between 1992 and the end of
Observations of interplanetary dust by the Juno magnetometer investigation
One of the Juno magnetometer investigation's star cameras was configured to search for unidentified objects during Juno's transit en route to Jupiter. This camera detects and registers luminous
Interplanetary Dust, Meteoroids, Meteors and Meteorites
Interplanetary dust particles and meteoroids mostly originate from comets and asteroids. Understanding their distribution in the Solar system, their dynamical behavior and their properties, sheds
Cosmic dust VIII
Fast, Computer-Assisted Detection of μm-Scale Dust Impact Craters on Spacecraft Materials
The NASA Stardust spacecraft included a collector array to capture particles entering the solar system from interstellar space. While a handful of likely interstellar dust grains were identified
Fast, computer‐assisted detection of dust and debris impact craters on Stardust interstellar foils
The NASA Stardust Interstellar Dust collection provides our current best sample set for direct laboratory analysis of dust grains from the contemporary interstellar dust stream. While a handful of


Stardust Interstellar Preliminary Examination IX: High‐speed interstellar dust analog capture in Stardust flight‐spare aerogel
The NASA Stardust mission used silica aerogel slabs to slowly decelerate and capture impinging cosmic dust particles for return to Earth. During this process, impact tracks are generated along the
Stardust Interstellar Preliminary Examination X: Impact speeds and directions of interstellar grains on the Stardust dust collector
On the basis of an interstellar dust model compatible with Ulysses and Galileo observations, we calculate and predict the trajectories of interstellar dust (ISD) in the solar system and the
Discovery of Jovian dust streams and interstellar grains by the Ulysses spacecraft
ON 8 February 1992, the Ulysses spacecraft flew by Jupiter at a distance of 5.4 AU from the Sun. During the encounter, the spacecraft was deflected into a new orbit, inclined at about 80° to the
Stardust Interstellar Preliminary Examination V: XRF analyses of interstellar dust candidates at ESRF ID13
Here, we report analyses by synchrotron X‐ray fluorescence microscopy of the elemental composition of eight candidate impact features extracted from the Stardust Interstellar Dust Collector (SIDC).
Stardust Interstellar Preliminary Examination XI: Identification and elemental analysis of impact craters on Al foils from the Stardust Interstellar Dust Collector
The Stardust Interstellar Preliminary Examination team analyzed thirteen Al foils from the NASA Stardust interstellar collector tray in order to locate candidate interstellar dust (ISD) grain
Perspectives on Interstellar Dust Inside and Outside of the Heliosphere
AbstractMeasurements by dust detectors on interplanetary spacecraft appear to indicate a substantial flux of interstellar particles with masses $>10^{-12}{\ {\rm g}}$ . The reported abundance of

With the discovery of bona fide extraterrestrial materials in the Stardust Interstellar Dust Collector, NASA now has a fundamentally new returned sample collection, after the Apollo, Antarctic
Interstellar dust close to the Sun
The low density interstellar medium (ISM) close to the Sun and inside of the heliosphere provides a unique laboratory for studying interstellar dust grains. Grain characteristics in the nearby ISM
Stardust Interstellar Preliminary Examination VII: Synchrotron X‐ray fluorescence analysis of six Stardust interstellar candidates measured with the Advanced Photon Source 2‐ID‐D microprobe
The NASA Stardust spacecraft exposed an aerogel collector to the interstellar dust passing through the solar system. We performed X‐ray fluorescence element mapping and abundance measurements, for
Interstellar Dust Inside and Outside the Heliosphere
In the early 1990s, after its Jupiter flyby, the Ulysses spacecraft identified interstellar dust in the solar system. Since then the in-situ dust detector on board Ulysses continuously monitored
