Astrochemical Inheritance of Terrestrial Planets Water from Local Wet Silicates
Lise Boitard-Crépeau, Stefano Pantaleone, Cecilia Ceccarelli +3
The delivery of water to the inner Solar System rocky planets, including Earth, remains debated, as standard models assume that they formed from dry grains, inside the snowline of…
Microscale Hydrogen, Carbon, and Nitrogen Isotopic Diversity of Organic Matter in Asteroid Ryugu
Larry R Nittler, Jens Barosch, Katherine Burgess +57
We report the H, C, and N isotopic compositions of microscale (0.2 to 2m) organic matter in samples of asteroid Ryugu and the Orgueil CI carbonaceous chondrite. Three regolith p…
Identification of Ammonium Salts on Comet 67P/C-G Surface from Infrared VIRTIS/Rosetta Data Based on Laboratory Experiments. Implications and Perspectives
Olivier Poch, Istiqomah Istiqomah, Eric Quirico +29
The nucleus of comet 67P/Churyumov-Gerasimenko exhibits a broad spectral reflectance feature around 3.2 m, which is omnipresent in all spectra of the surface, and whose attribut…
Science Priorities for the Extraction of the Solid MSR Samples from their Sample Tubes
N. Dauphas, S. S. Russell, D. Beaty +20
Preservation of the chemical and structural integrity of samples that will be brought back from Mars is paramount to achieving the scientific objectives of MSR. Given our knowledge…
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…
Investigating S-type asteroid surfaces through reflectance spectra of Ordinary Chondrites
J. Eschrig, L. Bonal, M. Mahlke +3
We present an in-depth study of the reflectance spectra of 39 equilibrated and 41 unequilibrated ordinary chondrites. We demonstrate that consistent measuring conditions are vital…
Nanoscale mineralogy and organic structure in Orgueil (CI) and EET 92042 (CR) carbonaceous chondrites studied with AFM-IR spectroscopy
Van T. H. Phan, Rolando Rebois, Pierre Beck +3
Meteorite matrices from primitive chondrites are an interplay of ingredients at the sub-micron scale, which requires analytical techniques with the nanometer spatial resolution to…
Miller Range 07687 and its place within the CM-CO clan
Trygve Prestgard, Lydie Bonal, Jolantha Eschrig +3
Miller Range (MIL) 07687 is a peculiar carbonaceous chondrite officially classified as a CO3. However, it has been found to display unique petrographic properties that are atypical…
Water abundance at the surface of C-complex main-belt asteroids
Pierre Beck, Jolantha Eschrig, Sandra Potin +4
Recently published space-based observations of main-belt asteroids with the AKARI telescope provide a full description of the 3 μm band, related to the presence of OH bearing miner…
Spectral reflectance analysis of type 3 carbonaceous chondrites and search for their asteroidal parent bodies
Jolantha Escrig, Lydie Bonal, Pierre Beck +1
Non-differentiated asteroids are among the most primitive objects in our Solar System, having escaped intense heating mechanisms. To help us understand the information contained in…
Mineralogy, chemistry and composition of organic compounds in the fresh carbonaceous chondrite Mukundpura: CM1 or CM2?
S. Potin, P. Beck, L. Bonal +7
We present here several laboratory analyses performed on the freshly fallen Mukundpura CM chondrite. Results of infrared transmission spectroscopy, thermogravimetry analysis and re…
The iron record of asteroidal processes in carbonaceous chondrites
A. Garenne, P. Beck, G. Montes-Hernandez +4
The valence of iron has been used in terrestrial studies to trace the hydrolysis of primary silicate rocks. Here, we use a similar approach to characterize the secondary processes,…
Style and intensity of hydration among C-complex asteroids: a comparison to dessicated carbonaceous chondrites
S. Potin, P. Beck, F. Usui +3
Here we report a comparison between reflectance spectroscopy of meteorites under asteroidal environment (high vacuum and temperature) and Main Belt and Near Earth Asteroids spectra…
Ammonium salts are a reservoir of nitrogen on a cometary nucleus and possibly on some asteroids
O. Poch, I. Istiqomah, E. Quirico +29
The measured nitrogen-to-carbon ratio in comets is lower than for the Sun, a discrepancy which could be alleviated if there is an unknown reservoir of nitrogen in comets. The nucle…
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…
ASIME 2018 White Paper. In-Space Utilisation of Asteroids: Asteroid Composition -- Answers to Questions from the Asteroid Miners
Amara L. Graps, Angel Abbud-Madrid, Paul Abell +41
In keeping with the Luxembourg government's initiative to support the future use of space resources, ASIME 2018 was held in Belval, Luxembourg on April 16-17, 2018. The goal of ASI…
Early formation of planetary building blocks inferred from Pb isotopic ages of chondrules
Jean Bollard, James N. Connelly, Martin J. Whitehouse +6
The most abundant components of primitive meteorites (chondrites) are millimeter-sized glassy spherical chondrules formed by transient melting events in the solar protoplanetary di…
The 15N-enrichment in dark clouds and Solar System objects
Pierre Hily-Blant, Lydie Bonal, Alexandre Faure +1
The line intensities of the fundamental rotational transitions of H13CN and HC15N were observed towards two prestellar cores, L183 and L1544, and lead to molecular isotopic ratios…
