India is conducting "dogfights" in space—a sophisticated maneuver where two satellites, a chaser and a target, engage in close-range orbital tactics, much like fighter jets in aerial combat, reported several Indian media outlets including NDTV. This is part of ISRO’s SPADEX mission, which aims to advance satellite docking, proximity operations, and autonomous flight capabilities.
Dogfights in space refer to coordinated, close-range maneuvers between satellites, similar to aerial dogfights between fighter jets. In India's case, ISRO has successfully executed this maneuver using its SPADEX mission, where a chaser and target satellite engage in precision orbital tactics.
The satellites, orbiting 500 km above Earth at speeds of 28,800 km/h, have successfully demonstrated docking, undocking, and power transfer between them.
These advancements position India among the elite nations mastering space docking and orbital maneuvering.
This follows similar exercises by China’s defense satellites in 2024, prompting global interest in space-based maneuverability. Last month, it was reported that the U.S. Space Force observed five Chinese satellites executing synchronized movements, practicing tactics for on-orbit space operations conducted in Low Earth Orbit (LEO), last year.
India’s SPADEX mission relies on cutting-edge rendezvous and docking technology to execute these satellite maneuvers. The key technologies involved include:
- Laser Range Finder & Visual Cameras – Used for precise navigation during close-range docking.
- Retroreflectors & Real-Time Imaging – Help align satellites during final approach.
- Inter-Satellite Communication Link (ISL) – Enables autonomous coordination between spacecraft.
- Indigenous Docking Mechanism – Developed by ISRO as part of the Bharatiya Docking System.
- Power Transfer Technology – Allows one satellite to supply energy to another, crucial for future space stations.
- Autonomous Rendezvous Strategy – Ensures satellites can approach and dock without human intervention.
