Proba-3 achieves precise formation flying
For the first time, two spacecraft in orbit were aligned in formation with millimeter precision and maintained their relative position for several hours without any control from the ground.
Space probes as a research area encompasses the design, deployment, and scientific utilization of uncrewed spacecraft sent beyond Earth orbit to investigate planetary bodies, small Solar System objects, and the heliosphere, and increasingly to perform astrophysical observations from deep space. Research focuses on mission architecture, autonomous navigation and operations, radiation-hardened avionics, long-duration power systems (e.g., RTGs, advanced solar arrays), high-gain communications, and in situ and remote-sensing payloads optimized for extreme environments. The field integrates planetary science, space plasma physics, and instrumentation, emphasizing data acquisition strategies, sample return capabilities, and technology maturation for future interplanetary and interstellar exploration.
