Precious Dust Two Mission Converge on Asteroid Sample Returns [PDF]

Far-flung spacecraft deliver incredible views of distant worlds. But there's nothing like bringing samples back to Earth. Instruments carried by spacecraft have limitations-of power, complexity, size, and number.

Disequilibrium oxygen isotope distribution among aqueously altered minerals in Ryugu asteroid returned samples

Meteoritics & Planetary Science
Oxygen 3‐isotope ratios of magnetite and carbonates in aqueously altered carbonaceous chondrites provide important clues to understanding the evolution of the fluid in the asteroidal parent bodies.

Surface Modifications of a Space-weathered Ryugu Sample and the Reflectance Spectral Response

The Planetary Science Journal
Reflectance spectra from the surface of asteroid Ryugu, measured by the Hayabusa2 spacecraft, exhibit a metal-OH absorption at ∼2.7 μ m that is approximately half as deep as the returned samples measured in the laboratory and shifted toward longer ...

Constraining the Effects of Pre- and Post-accretionary Processes on Ryugu Insoluble Organic Matter

The Astrophysical Journal
Asteroidal and cometary fragments have been indicated as possible sources of the building blocks of life for the early Earth. Samples returned from the asteroid Ryugu are uncontaminated and contain organic matter.

Evidence for Magnetically‐Driven Accretion in the Distal Solar System

AGU Advances
Paleomagnetic measurements of meteorites indicate that magnetic fields existed in the inner solar nebula capable of driving accretion at rates similar to those observed for young stellar objects with protoplanetary disks.
