Space Autonomous Vehicles (SAVs) are robotic spacecraft using AI and pre-programmed logic for missions too risky or complex for humans, enabling independent navigation, docking, resource gathering (like lunar rovers), and scientific research, reducing costs, human error, and communication delays, with key examples including Mars rovers and the reusable X-37B spaceplane, forming the backbone of modern space exploration and infrastructure.

Key Characteristics
AI & Robotics: Utilize cameras, sensors, and AI for real-time decision-making, pathfinding, and obstacle avoidance, much like self-driving cars.
Levels of Autonomy: Range from basic remote control to full independence, executing complex tasks like docking, resource extraction, and surveying.
Mission Types: Include satellites, rovers (Mars, Moon), probes, and reusable spaceplanes (X-37B) for observation, defense, logistics, and research.

Benefits & Importance
Enables Deep Space: Operates in harsh environments (radiation, extreme temps) beyond human tolerance.
Cost Reduction: Less need for constant ground control, lowering operational expenses.
Increased Reliability: Minimizes human error (PEBCAK).
New Capabilities: Opens possibilities for In-Situ Resource Utilization (ISRU) and complex orbital servicing.
Examples
NASA’s Mars Rovers (Curiosity, Perseverance): Navigate Martian terrain, identify targets.
Boeing’s X-37B: Uncrewed spaceplane for technology testing and experiments.
Starfish Space’s Otter: Demonstrating autonomous rendezvous and docking in orbit.
Future & Applications
Space Logistics: Creating autonomous networks for rapid global and interplanetary delivery.
Lunar/Mars Bases: Rovers for resource prospecting and construction.
Defense & Security: Autonomous orbital systems for monitoring and security.
