In the future of space travel, spacecraft must be capable of finding each other and docking without human intervention. This is precisely the goal of the Low Earth Orbiting Navigation Experiment for Spacecraft Testing Autonomous Rendezvous and Docking, also known as the STARD (Spacecraft Testing Autonomous Rendezvous and Docking) project.
Led by Darryl May from NASA’s Johnson Space Center and supported by researchers at Texas A&M University and the University of Texas, this experiment focused on refining the navigation and control technologies needed for two spacecraft to meet and connect autonomously in space.
This capability is critical not only for resupply missions to the ISS but also for assembling spacecraft in orbit, servicing satellites, or establishing lunar and Martian habitats. The experiment ran during Expeditions 43 through 48 and involved using real-time data from sensors and navigation systems to simulate close-approach operations.
The testing examined how different software algorithms handled sensor input and how accurately they could guide spacecraft to their targets. Engineers also looked at how microgravity affected the process and how environmental conditions like lighting and orbital debris might influence autonomous docking.
The experiment provided key insights into GPS-based navigation, sensor fusion, and real-time control systems in orbit. The data gathered helped engineers design more reliable autonomous systems, paving the way for fully automated spacecraft missions.
By building smarter spacecraft, we reduce the need for manual control and increase the safety and flexibility of space missions. It’s another leap toward creating sustainable space infrastructure.
