ISRO executes advanced satellite manoeuvres resembling aerial dogfights using leftover SPADEX mission fuel. Two satellites (SDX 01 & 02) coordinated at 28,800 km/h—28x faster than a passenger jet.
- The SPADEX mission (launched to test autonomous docking) left 50% fuel unused due to precise execution.
- ISRO repurposed this fuel for an unplanned orbital combat simulation—a first for India.
- The SDX 01 and SDX 02 satellites performed high-speed maneuvers at 28,800 km/h, showcasing:
- Close-proximity operations
- Rapid repositioning
- Potential anti-satellite (ASAT) applications
Global Context: US vs China Space Rivalry
In March 2025, the US Space Force warned about China’s satellite dogfighting tests. US General Michael A. Guetlein stated:
“China is practicing on-orbit combat tactics between satellites—what we call space dogfights.” India’s test signals its growing counter-space capabilities, joining the US and China in advanced orbital warfare tech.
Why This Matters?
- Strategic Deterrence: Proves India can defend its satellites against hostile actions.
- Fuel Efficiency: Highlights ISRO’s ability to repurpose mission resources creatively.
- Space Militarization: Positions India as a key player in evolving space security dynamics.
