The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review
Journal of Field Robotics, EarlyView.ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Geometric Characterization of LEO–GEO Inter‐Satellite Links for Bidirectional Communications
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Incorporating geosynchronous Earth orbit (GEO) and low Earth orbit (LEO) satellites can extend communication services far beyond the reach of terrestrial infrastructure. A key enabler of such architectures is the establishment of inter‐satellite links (ISLs) between LEOs and GEOs to support bidirectional communications.
