Arresting-Cable System for Robust Terminal Landing of Reusable Rockets

“…In the first navigation step, significant achievements have been made by learning from various mature Mars landing technologies accumulated over the past 50 years [8,9]. Now, based on well-developed high-precision guidance technologies, the guidance errors have been diminished from kilometers to meters with nearly minimum fuel consumption [10][11][12]. In the second terminallanding step, the current vertical-recovery technique requires not only advanced engines that are capable of multiple restarts and thrust modulation within a large range [13][14][15] but also an accurate control system to prevent the rocket from crashing [16,17].…”
