Ryugu Reference Project: Recommendations from the Measurement Definition Team
Meteoritics &Planetary Science, EarlyView.Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,

Mountain‐top spherules: Criteria to identify natural and synthetic particles
Meteoritics &Planetary Science, EarlyView.Abstract Natural microspherules are important tracers of geologic and environmental processes in modern and ancient deposits. However, anthropogenic contamination can dilute natural collections by releasing synthetic microspherules into the environment.

Aqueous alteration in C2‐ung Bells through the analysis of carbonates – Does a CR origin ring true?
Meteoritics &Planetary Science, EarlyView.Abstract Bells is an ungrouped carbonaceous chondrite that has in recent years been proposed as a CR‐an. This link to CR chondrites has previously been identified through the analysis of anhydrous silicates, for example, oxygen isotopic compositions of olivine (Marrocchi et al., 2023).

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract Geologic carbon sequestration (GCS) is widely seen as essential to achieving net‐zero emissions, yet its large‐scale deployment remains impractical mainly due to economic and political reasons. In this article, we explore the idea that enhanced oil recovery (EOR) may serve as a pragmatic steppingstone for getting GCS‐ready infrastructure in ...

The Earth's Greatest Porous Media
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

High energy astrophysical processes
, 2005 We briefly review the high energy astrophysical processes that are related to the production of high energy $ $-ray and neutrino signals and are likely to be important for the energy loss of high and ultrahigh energy cosmic rays. We also give examples for neutrino fluxes generated by different astrophysical objects and describe the cosmological link ...

Researchers' Well‐Being Through My Academic Career in Japan, Germany and USA
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract Upon development of my academic career in Japan, Germany, and USA, I have increasingly recognized the importance of researchers' well‐being. While the research lifestyles in these three countries were distinct, it has been essential for me to maintain good well‐being for the sustainable development of my academic career.
