Identifying LL Chondrite Near-Earth Asteroids Using LL Chondrite Reflectance Spectra
The Astrophysical Journal LettersMost near-Earth objects are thought to originate from the collisional fragments of the main asteroid belt. One question that remains to be resolved is the proportion of near-Earth objects sampling the core area material of the parent body to the outer ...

Utopia Remembers: The Soviet Past in the Imagined Communist Future
The Russian Review, EarlyView.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.

Experimental Physiology, EarlyView.Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Asteroid Albedo and Size Inversion: A Deep Learning Method and Application Based on Multiparameters
The Astrophysical Journal Supplement SeriesOf nearly 1.5 million asteroids discovered to date, only about 5% have spectroscopic observations, resulting in limited physical property coverage. Multicolor photometry provides taxonomic classifications for the majority of asteroids.
