The New Space Race Era: The Exogeoheritage Challenge and Its Conservation
Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract The escalating pace of space exploration has ushered in a new era reminiscent of the space race of the 1960s. However, the discourse on exogeoconservation—the protection of geological heritage—now demands a prominent place in decision‐making processes.

Long-Lived In-Situ Solar System Explorer (LLISSE): Potential Contributions to the Next Decade of Solar System Exploration [PDF]
Venus, while having similar size, mass, and location in the solar system to Earth, varies from Earth in many ways and holds many scientific mysteries despite many missions that have focused on it in the past.

Characterizing Volcanic Eruptions on Venus: Some Realistic (?) Scenarios [PDF]
, 2011 When Pioneer Venus arrived at Venus in 1978, it detected anomalously high concentrations of SO2 at the top of the troposphere, which subsequently declined over the next five years.

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 122-139, January 2026.Abstract The O‐, N‐, Mo‐, Ru‐, Os‐, Cr‐, Ti‐, Ni‐, Fe‐, Nd‐, Ca‐, Zn‐, Sr‐, and Mg‐isotopic compositions of enstatite chondrites are essentially identical to those of the Earth and Moon. These correspondences suggest enstatite chondrites formed at ≈1 AU as the only known chondrite groups that accreted in the vicinity of a major planet. Bulk Earth has a

The Astrophysical Journal LettersBecause of its rotation period of 243 days, Venus is considered a slowly rotating planet. However, its persistent superrotating atmospheric jets, which increase in speed from surface to cloud tops, effectively set a faster rotation speed than the surface

New Phytologist, Volume 249, Issue 1, Page 359-372, January 2026.Summary Pyrenoids are algal CO2‐fixing organelles that mediate approximately one‐third of global carbon fixation. Most pyrenoids are traversed by membranes that are thought to supply them with concentrated CO2. Despite the critical nature of these membranes for pyrenoid function, they are poorly understood, with few protein components known in any ...
