Liquid-Propellant Rocket Engine Throttling: A Comprehensive Review [PDF]
Journal of Propulsion and Power, 2009 Liquid-propellant rocket engines are capable of on-command variable thrust or thrust modulation, an operability advantage that has been studied intermittently since the late 1930s. Throttleable liquid-propellant rocket engines can be used for planetary entry and descent, space rendezvous, orbital maneuvering including orientation and stabilization in ...

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 ...
