[Séminaire IRAP] Ce jeudi, les personnels de l'IRAP accueilleront Guy Libourel ( @umrGeoazur , Nice) qui offrira une brève restrospective de la mission #OsirisRex (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) de retour d'échantillons de #Bennu, un astéroïde primitif géocroiseur,
et présentera les résultats majeurs obtenus par l’équipe scientifique internationale concernant #Bennu : https://www.irap.omp.eu/event/osirix-rex-une-mission-historique-de-retour-dechantillons-dun-asteroide-primitif/

Bennu Asteroid Samples Show Uneven Distribution of Organic Compounds and Minerals

A recent study of samples collected from asteroid Bennu by NASA’s OSIRIS-REx mission reveals that the asteroid’s chemistry is highly heterogeneous. Scientists found that organic compounds and minerals…

Spannend, die Bausteine des Lebens scheinen in vielen Meteoriten vorzukommen, wie jetzt eine Untersuchung an Proben von #Bennu, #Ryugu und zwei auf der Erde gefundenen Meteoriten nachgewiesen wurde.

Asteroiden wie Bennu, Ryugu etc. enthalten „Bausteine des Lebens“

Die Raumsonde Hayabusa 2 hat 2018/2019 den Asteroiden Ryugu besucht, ist gelandet und hat 2022 Proben auf der Erde abgeliefert. In diesen Proben wurden Aminosäuren (als Bausteine des Lebens) gefunden.

Organic #molecules delivered from #extraterrestrial materials may have played a key role in supplying building blocks for #life on #Earth.

Now scientists report all five canonical #nucleobases—purines (#adenine and #guanine) and pyrimidines (#cytosine, #thymine and #uracil)—in samples returned from the C-type #asteroid (162173) #Ryugu.

Samples from Ryugu, #Bennu and #Orgueil, which have a similar mineralogy and elemental composition, show purine-to-pyrimidine ratios negatively correlating with #ammonia.

These observations indicate that the nucleobases in these samples may have formed via a shared pathway depending on the physicochemical environment of the respective parent bodies.

The detection of diverse nucleobases in asteroid and meteorite materials demonstrates their widespread presence throughout the Solar System and reinforces the hypothesis that carbonaceous asteroids contributed to the #prebiotic chemical inventory of early Earth.

A complete set of canonical nucleobases in the carbonaceous asteroid (162173) Ryugu - Nature Astronomy

Samples returned from the asteroid Ryugu contain all five canonical nucleobases (A, G, C, T and U). Their presence in Ryugu and Bennu supports the hypothesis that carbonaceous asteroids contributed to the prebiotic chemical inventory of early Earth.

Asteroid Bennu’s Rugged Surface Baffled NASA, We Finally Know Why

In one of the biggest surprises of NASA's OSIRIS-REx mission, its target asteroid, Bennu, turned out to be a jagged, rugged world covered in large boulders, with few of the smooth patches of sandy or pebbly material scientists had expected based on observations with Earth-based instruments. Bennu's looks were quite deceiving, and until now, scientists struggled to figure out why.

Low thermal inertia of carbonaceous asteroid Bennu driven by cracks observed in returned samples - Nature Communications

Thermal inertia is used to infer physical properties of asteroid surfaces. Here, authors propose that the low thermal inertia of asteroids Bennu and Ryugu is driven by cracks in rocks resulting from geological processes within the parent body – or more recently through micrometeorite impacts
