Planetary Geology: Goals, Future Directions, and Recommendations [PDF]

open access: yes
Planetary exploration has provided a torrent of discoveries and a recognition that planets are not inert objects. This expanded view has led to the notion of comparative planetology, in which the differences and similarities among planetary objects are ...

Bioinspired Twisted Artificial Muscles with Enhanced Performance for Underwater Applications

open access: yesAdvanced Science, EarlyView.
A climbing plant‐inspired twisted artificial muscle (TAM) with a braided configuration and seal‐inspired thermal insulation enables high‐performance underwater actuation. Enhanced deformation, reduced heat dissipation, and rapid motion are validated through a bionic ray that exhibits straight and turning motions.

Active Seismic Exploration of Planetary Subsurfaces via Compressive Sensing

open access: yesEarth and Space Science
Geophysical measurements, such as seismic experiments, are a key target for scientific activities on planetary surfaces. Dense spatial sampling of such measurements is often desirable, and acquisition is traditionally performed at regular intervals ...
