The main limitations of standard nadir-looking radar altimeters have been knownfor long. They include the lack of coverage (intertrack distance of typically 150 km for theT/P / Jason tandem), and the spatial resolution (typically 2 km for T/P and Jason),

Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Parameterization of Fuel-Optimal Synchronous Approach Trajectories to Tumbling Targets
Docking with potentially tumbling Targets is a common element of many mission architectures, including on-orbit servicing and active debris removal. This paper studies synchronized docking trajectories as a way to ensure the Chaser satellite remains on ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Analytical Modeling of LEO Satellite Mutual Visibility under Perturbations
This present study develops an analytical model for mutual visibility in perturbed Low Earth Orbit (LEO), explicitly accounting for Earth’s oblateness (J2 and J3) and atmospheric drag.

Intermediary LEO propagation including higher order zonal harmonics
Two new intermediary orbits of the artificial satellite problem are proposed. The analytical solutions include higher order effects of the geopotential, and are obtained by means of a torsion transformation applied to the quasi-Keplerian system resulting

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots
Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...
