Futures of Everyday Life: A Qualitative Content Analysis of Future Personas in Scenarios

FUTURES &FORESIGHT SCIENCE, Volume 8, Issue 1, April 2026.
ABSTRACT Scenario reports, holding a long‐standing tradition in foresight and futures studies, act as an essential document for organizations to prepare for possible, plausible, and alternative futures. Focusing on descriptions and representations of everyday life, we examined 29 future persona narratives from six publications—covering a wide field ...

Optimized Asteroid Rotation and Shape Modeling through an Integrated Shape-from-silhouette and Optical Flow Approach

The Astronomical Journal
Asteroids offer valuable insights into the formation and evolution of the solar system. Understanding their rotation and shape is essential for studying asteroid collision histories and geological processes, as well as for planning exploration missions ...

Effects of asteroid belt and oblateness on the stability and orbits near triangular Lagrange points

Results in Physics
This study investigates the dynamics of an infinitesimal body within the context of the restricted three-body problem, incorporating perturbations arising from the asteroid belt and the oblateness effects of the three bodies.

EFFECT OF NON-SPHERICITY OF GRAVITATIONAL FIELD OF THE ASTEROID ON THE ITS SATELLITES ORBITS EVOLUTION

Odessa Astronomical Publications, 2016
Lately it has become possible to sufficiently precise definition of the physical and geometric characteristics of asteroid systems using radar observations (http://echo.jpl.nasa.gov/~lance/binary.neas.html), which allowed calculating the asymmetry of the

A Simplified Ordinary Differential Equation for the Surface Temperature of Airless Bodies

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract In this work, we develop simplified surface temperature models for spherical bodies with insignificant atmospheres, able to produce a latitude/longitude temperature map that includes seasonality effects. We start from the commonly employed depth‐dependent model by Spencer et al. (1989, https://doi.org/10.1016/0019‐1035(89)90182‐6) based on the

Radiation Forces and Trajectory of Hayabusa2♯ Target 1998 KY26

The Astrophysical Journal Letters
Small near-Earth asteroid 1998 KY _26 has recently become an object of interest because it is the target of the Hayabusa2 ♯ mission and because challenges in fitting its astrometric data have led to classifying it as a dark comet.

Orbital Transfers in a Binary Asteroid System Considering Flattening of the Bodies and Solar Radiation Pressure

Aerospace
This paper aims to investigate the effects of asteroid size and shape and solar radiation pressure in the trajectories of a spacecraft in transfers between the collinear equilibrium points of a binary non-spherical asteroid system.

Phase‐Space Synchronization Driven by Moon‐Magnetosphere Coupling in Gas Giants

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We present a new theoretical framework to describe the rapid and spatially localized loss of energetic particles in planetary radiation belts, focusing on interactions between gas giant magnetospheres and their moons. Observations show that flux depletions—known as microsignatures—often refill on timescales comparable to a single drift period,
