Pre-accretional irradiation of comet 67P/Churyumov-Gerasimenko constituents
Inès Sansberro, Nicolas Fray, Hervé Cottin +11
Comets are thought to have largely preserved the primordial material from which they formed. Therefore, cometary studies provide important clues about the processes involved in the…
Chemical and physical properties of cometary dust
Cecile Engrand, Jérémie Lasue, Diane H. Wooden +1
Cometary dust particles are best preserved remnants of the matter present at the onset of the formation of the Solar System. Space missions, telescopic observations and laboratory…
Presolar stardust in asteroid Ryugu
Jens Barosch, Larry R. Nittler, Jianhua Wang +121
We have conducted a NanoSIMS-based search for presolar material in samples recently returned from C-type asteroid Ryugu as part of JAXA's Hayabusa2 mission. We report the detection…
AMBITION -- Comet Nucleus Cryogenic Sample Return (White paper for ESA's Voyage 2050 programme)
D. Bockelée-Morvan, G. Filacchione, K. Altwegg +27
This white paper proposes that AMBITION, a Comet Nucleus Sample Return mission, be a cornerstone of ESA's Voyage 2050 programme. We summarise some of the most important questions s…
Dust of comet 67P/Churyumov-Gerasimenko collected by Rosetta/MIDAS: classification and extension to the nanometre scale
T. Mannel, M. S. Bentley, P. D. Boakes +9
The properties of the smallest subunits of cometary dust contain information on their origin and clues to the formation of planetesimals and planets. Compared to IDPs or particles…
Identification of organic molecules with a laboratory prototype based on the Laser Ablation-CosmOrbitrap
L. Selliez, C. Briois, N. Carrasco +18
In the Solar System, extra-terrestrial organic molecules have been found on cometary primitive objects, on Titan and Enceladus icy moons and on Mars. Identification could be achiev…
Dome C UltraCarbonaceous Antarctic MicroMeteorites Infrared and Raman fingerprints
E. Dartois, C. Engrand, J. Duprat +5
UltraCarbonaceous Antarctic MicroMeteorites (UCAMMs) represent a small fraction of interplanetary dust particles reaching the Earth's surface and contain large amounts of an organi…
Evidence for depletion of heavy silicon isotopes at comet 67P/Churyumov-Gerasimenko
M. Rubin, K. Altwegg, H. Balsiger +17
Context. The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) was designed to measure the composition of the gas in the coma of comet 67P/Churyumov-Gerasimenko, t…
COSIMA-Rosetta calibration for in-situ characterization of 67P/Churyumov-Gerasimenko cometary inorganic compounds
Harald Krüger, Thomas Stephan, Cécile Engrand +15
COSIMA (COmetary Secondary Ion Mass Analyser) is a time-of-flight secondary ion mass spectrometer (TOF-SIMS) on board the Rosetta space mission. COSIMA has been designed to measure…
