Semi-analytical guidance algorithm for autonomous close approach to non-cooperative low-gravity targets [PDF]

, 2014
An adaptive guidance algorithm for close approach to and precision landing on uncooperative low-gravity objects (e.g. asteroids) is proposed. The trajectory, updated by means of a minimum fuel optimal control problem solving, is expressed in a polynomial

Food limitation erodes the thermal tolerance of larvae in an ecologically influential marine herbivore

Ecology, Volume 107, Issue 1, January 2026.
Abstract Biologists often use organismal thermal tolerance to help explain or forecast responses of populations to climate change. Yet many studies quantify thermal tolerance under isolated laboratory conditions despite extreme events, such as heatwaves, often coinciding with other stressors such as nutrient or food limitation.

On the Stability Barrier of Hermite Type Discretizations of Advection Equations

Numerical Methods for Partial Differential Equations, Volume 42, Issue 1, January 2026.
ABSTRACT We establish a stability barrier for a class of high‐order Hermite‐type discretization of 1D advection equations underlying the hybrid‐variable (HV) and active flux (AF) methods. These methods approximate both cell averages and nodal solutions and evolve them in time simultaneously.

Earth's Minimoons: Opportunities for Science and Technology

Frontiers in Astronomy and Space Sciences, 2018
Twelve years ago the Catalina Sky Survey discovered Earth's first known natural geocentric object other than the Moon, a few-meter diameter asteroid designated 2006 RH120. Despite significant improvements in ground-based telescope and detector technology

Asteroid secular dynamics: Ceres' fingerprint identified

, 2015
Here we report on the significant role of a so far overlooked dynamical aspect, namely a secular resonance between the dwarf planet Ceres and other asteroids.

Formation of Asteroid (16) Psyche by a Giant Impact

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

Orbital Capture of Ejecta into Periodic Orbits around Binary Asteroid (65803) Didymos

The Planetary Science Journal
The successful impact of the Double Asteroid Redirection Test (DART) spacecraft on Dimorphos enabled the first-ever extensive observation of a postimpact ejecta tail from a binary asteroid system.

New Insolation Forcing for Paleoclimate Studies

Paleoceanography and Paleoclimatology, Volume 41, Issue 1, January 2026.
Abstract Insolation forcing at the top of the atmosphere is widely used in paleoceanographic and paleoclimatological studies. In paleoclimate simulations, it must reflect Earth’s orbital history. General Circulation Models (GCMs) typically use a modern orbital configuration to allow direct comparison to modern and near‐future scenarios, often with time

The Network State, Exit, and the Political Economy of Venture Capital

Antipode, Volume 58, Issue 1, January 2026.
Abstract This article focuses on the Network State movement as embodying the venture capital (VC) logic of exit. Exit constitutes both a strategy for lucrative returns and an ideology seeking out new territories for financial and technological speculation.
