TL;DR: In this paper, the authors describe the critical role that synchrotron X-ray and infrared microprobes are playing in the search for interstellar dust in the Stardust Interstellar Dust Collector (SIDC).
Enceladus Icy Jet Analyzer (ENIJA) : Search for life with a high resolution TOF-MS for in situ characterization of high dust density regions
R. Srama,Frank Postberg,H. Henkel,T. Klopfer,Yanwei Li,Jonas Simolka,S. Bugiel,Sascha Kempf,Jon K. Hillier,Nozair Khawaja,Mario Trieloff,Bernd Abel,Georg Moragas-Klostermeyer,Heiko Strack,J. Schmidt,Rachel Soja,Zoltan Sternovsky,Tilman Spohn +17 more
TL;DR: The Enceladus Icy Jet Analyzer (ENIJA) as mentioned in this paper is a time-of-flight mass spectrometer for compositional analysis of submicron and micronsized dust particles.
Journal ArticleDOI
A cosmic dust detection suite for the deep space Gateway
P.J. Wozniakiewicz,John Bridges,Mark J. Burchell,William Carey,James Carpenter,V. Della Corte,A. Dignam,M.J. Genge,L. J. Hicks,Martin Hilchenbach,Jon K. Hillier,A.T. Kearsley,Harald Krüger,Sihane Merouane,Ernesto Palomba,F. Postberg,J. Schmidt,R. Srama,Mario Trieloff,M. van-Ginneken,Veerle Sterken +20 more
TL;DR: In this paper, a model payload of detectors for measuring the dust flux in the vicinity of the Moon is described, and the authors predict that the flux is sufficient to permit studies of cometary vs. asteroidal dust and their composition, and to sample interstellar dust streams.
Complex Organic Macromolecular Compounds in Ice Grains from Enceladus
Frank Postberg,Nozair Khawaja,Sascha Kempf,J. H. Waite,Christopher R. Glein,H. W. Hsu,R. Srama +6 more
TL;DR: In this article, the authors used the Cosmic Dust Analyser (CDA) to produce time-of-flight mass spectra of cations generated by high-velocity impacts of individual grains onto a metal target.

TL;DR: The Stardust Interstellar Dust Collection tray as discussed by the authors provides the first opportunity for the direct laboratory-based measurement of contemporary interstellar dust, and has already revealed 16 tracks from particle impacts with an orientation consistent with an interstellar origin, and to date four of the particles associated with these tracks have a composition consistent with the extraterrestrial origin.
