Elastic Properties of Titan Tholins Revealed by Brillouin Spectroscopy
Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract Titan tholins, complex organic solids synthesized by simulating photochemical processes in Titan's atmosphere, are widely regarded as analogs to organic surface materials on the Saturnian moon. Their mechanical properties are critical for understanding the evolution of Titan's geomorphology and crustal layering.

Phase Curves of Kuiper Belt Objects, Centaurs, and Jupiter-family Comets from the ATLAS Survey
The Planetary Science Journal, 2023 The Kuiper Belt objects (KBOs), the Centaurs, and the Jupiter-family comets (JFCs) form an evolutionary continuum of small outer solar system objects, and their study allows us to gain insight into the history and evolution of the solar system. Broadband

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2549-2566, October 2026.Abstract This study investigates the petrography and mineralogy of three L‐type ordinary chondrite meteorites: Northwest Africa (NWA) 4137 (L6), Homestead (L5), and Kunashak (L6). We studied the shock‐related deformation features in the matrix and the characteristics of the melt veins, including the presence or absence of high‐pressure (HP) phases. Our

Evidence for Random Walk Transport of Small Asteroids from the Main Belt to the Inner Solar System
The Planetary Science JournalThe transport of some main-belt asteroids to the inner solar system depends on Yarkovsky radiation forces changing the orbits of those asteroids. However, these forces depend on the rotational states of the asteroids, and YORP radiation forces act to ...

Masses of asteroids and total mass of the main asteroid belt [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractAn estimation of the mass of the main asteroid belt was made on the basis of the new version of EPM2014 ephemerides of the Institute of Applied Astronomy of Russian Academy of Sciences using about 800000 positional observations of planets and spacecraft.

Geography of the asteroid belt [PDF]
, 1978 The CSM classification serves as the starting point on the geography of the asteroid belt. Raw data on asteroid types are corrected for observational biases (against dark objects, for instance) to derive the distribution of types throughout the belt ...

Accessibility of the resources of near Earth space using multi-impulse transfers [PDF]
, 2010 Most future concepts for exploration and exploitation of space require a large initial mass in low Earth orbit. Delivering this mass requires overcoming Earth's natural gravity well, which imposes a distinct obstacle to space-faring.

Utopia Remembers: The Soviet Past in the Imagined Communist Future
The Russian Review, Volume 85, Issue 4, Page 478-494, October 2026.Abstract After a twenty‐five‐year hiatus, the reappearance of utopian literature in 1957 prompted Soviet literary watchdogs to corral the subgenre into an ideologically‐acceptable mold. A key requirement was for future generations to be depicted as reverently commemorating the past.

Asteroids Fail to Retain Cometary Impact Signatures
The Planetary Science JournalA bombardment of comets is thought to have occurred in the inner solar system as a result of a dynamical instability among the giant planets after gas disk dispersal.
