🇯🇵 #JAXA 📆 June 7, 2023 #Hayabusa2 #Ryugu ☄️mission summary 🔬 : #minerals were found to have formed about 5 million years after the start of the #SolarSystem 🌌 (now 4.56 billion years old). https://cosmos.isas.jaxa.jp/the-sample-from-asteroid-ryugu-summary-early-2023/
The #NASA #osirisrex mission is scheduled to bring a sample from asteroid #Bennu back to #Earth 🌏 this September.

Oooh. Now I don't feel so old. :)

Writer Fuel: The "Building blocks of life" recovered from asteroid Ryugu are older than the solar system itself.

Spectral Type and Geometric Albedo of (98943) 2001 CC21, the #Hayabusa2# Mission Target: https://arxiv.org/abs/2304.02917 - "we conclude that JAXA's Hayabusa2# spacecraft will explore an S-type asteroid with albedo and size (0.42-0.56 km when we assume the absolute magnitude of 18.6) similar to (25143) Itokawa."

Japan's #Hayabusa2 probe brought back a molecular component of #RNA and vitamin B (niacin) in the carbon sample it took from asteroid Ryugu. That's (some of) ingredients for life in outer #space.

Les équipes analysant les échantillons de l'astéroïde #Ryugu ont détecté la présence d'uracile, l'une des "lettres de l'alphabet génétique" de l'ARN. Un très beau succès (un de plus !) pour la mission japonaise #Hayabusa2. Ca ne veut évidemment pas dire qu'il y a de la vie sur Ryugu, mais que ce type d'objet a pu apporter sur Terre des ingrédients importants pour l'émergence de la vie.
J'ai répondu à ce sujet à une courte interview de la @RTSInfo

Combined with the findings from Japan's SRMs (#Hayabusa1 and #Hayabusa2), this mission will contribute enormously to what we know about the origin and early stages of our universe. I can't wait!

Massimo Luciani - Uracil and vitamin B3 found in samples from asteroid Ryugu:

Samples of #asteroid #Ryugu collected by #Hayabusa2 had #uracil, one of the informational units that make up #RNA, the molecules that contain the instructions for how to build and operate living organisms. Vitamin #B3 or #niacin, which is an important cofactor for #metabolism in living organisms, was also detected in the same samples

'En junio de 2018, después de un viaje de tres años y medio, la sonda #Hayabusa2 de la Agencia Japonesa el Espacio (JAXA) llegó al asteroide #Ryugu, a 150 millones de kms. aprox. de distancia. Tras tomar muestras, la sonda dejó caer una cápsula con el preciado botín sobre el desierto de Australia en diciembre de 2020. Preservadas de todo contacto, hoy se han difundido los resultados del análisis de esas muestras. Presentan dos componentes básicos para la vida: #uracilo, una de las unidades que componen el #ARN –las moléculas que contienen las instrucciones para construir y hacer funcionar los organismos vivos–, y vitamina B3 o niacina.'

A new study of samples brought back from the #Ryugu asteroid by the #JAXA mission #Hayabusa2, helped to characterize and map different types of carbonate minerals within the samples.

A near-infrared hyperspectral microscope developed by #IAS has been analyzing the entire collection of samples. Hundreds of carbonate-rich zones were detected, including carbonate-rich grains and inclusions that formed within the first millions of years of evolution of our #SolarSystem.

Sunburnt asteroids?! Turns out this resolves a question I've had for ages. When the #Hayabusa2 spacecraft visited #asteroid #Ryugu, the in-situ observations suggested the whole asteroid might have been dried out. But when the sample was returned to Earth, analysis found it packed with hydrated minerals. Sooooo why the contradiction?! Turns out, space weathering can dry out just the top layer. Press release by the authors and chalkboard explainer by me! Link: https://www.isas.jaxa.jp/en/topics/003273.html

#Mastodon! Let's have a #quiz!

Both #asteroid #Ryugu (the destination of the #JAXA #Hayabusa2 mission) and asteroid #Bennu (destination of the #NASA #OSIRISREx mission) are shaped like spinning tops, with a bulging equatorial region. What is thought to be the reason for this shape?
