Orbital dynamics of earth-orbiting 'smart dust' spacecraft under the effects of solar radiation pressure and aerodynamic drag [PDF]
, 2010 This paper investigates how the perturbations due to asymmetric solar radiation pressure, in presence of Earth's shadow, and atmospheric drag can be balanced to obtain long-lived Earth centered orbits for swarms of SpaceChips, without the use of active ...

Thermodynamic Properties of MgAl2O4 Spinel at High Temperatures and High Pressures
Crystals, 2023 Thermodynamic properties of MgAl2O4 spinel are significant in understanding the phase relations of the Earth’s crust and upper mantle, but available values from experimental measurements are limited at ambient pressure conditions to date.

Heliotropic dust rings for Earth climate engineering
, 2013 This paper examines the concept of a Sun-pointing elliptical Earth ring comprised of dust grains to offset global warming. A new family of non-Keplerian periodic orbits, under the effects of solar radiation pressure and the Earth's J(2) oblateness ...

Revisiting Active and Passive Earth Pressure Problems using Three Stability Factors
, 2023 This paper presents rigorous plasticity solutions to the classical active and passive earth pressure problems. The primary method adopted is a conventional equation based on the soil property and three stability factors (Fc, Fs, and Fγ), that are ...

Using dimers to measure biosignatures and atmospheric pressure for terrestrial exoplanets
, 2014 We present a new method to probe atmospheric pressure on Earth-like planets using (O-O) dimers in the near-infrared. We also show that dimer features could be the most readily detectable biosignatures for Earth-like atmospheres and may even be detectable

Ab initio study of the elastic behavior of MgSiO3 ilmenite at high pressure [PDF]
, 1999 We investigate the athermal high pressure behavior of the elastic properties of MgSiO3 ilmenite up to 30 GPa using the ab initio pseudopotential method. Our results at zero pressure are in good agreement with single-crystal elasticity measurements.

Deep carbon cycle constrained by carbonate solubility
Nature Communications, 2021 Carbonate mineral aqueous solubility decreases as carbonates become more Mg-rich during subduction. Coupled with regional variations in amounts of carbon and water subducted, this explains discrepancies in estimates of carbon recycling, suggesting that ...
