India could soon join an elite club of nations with space docking technology as the Indian Space Research Organisation (ISRO) successfully launched its Space Docking Experiment (SpaDeX) mission, which aims to demonstrate the capability to dock two satellites in orbit. This is a crucial step for India's future space missions, including the planned Bharatiya Antariksh Station (BAS) and lunar missions.
With launch of PSLV-C60 rocket, on Monday, December 30, 2024, from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, ISRO has indeed made a significant leap with the successful launch of its SpaDeX mission.
The docking process is expected to take place around January 7, 2025. If successful, India will join an elite group of nations with space docking capabilities, including the United States, Russia, and China. The country could be fourth nation globally to have space docking technology.
SpaDeX aims to demonstrate the capability to dock two satellites in orbit, a crucial technology for future space missions. Two small satellites, named Chaser and Target, each weighing around 220 kg, were deployed into a 470 km orbit.
The SpaDeX mission objective to demonstrate the technology required for rendezvous, docking, and undocking of two small spacecraft (SDX01, the Chaser, and SDX02, the Target) in a low-Earth circular orbit.
This technology is essential for India's plans to build its own space station, the Bharatiya Antariksh Station (BAS), and for upcoming lunar missions.
The SpaDeX (Space Docking Experiment) mission by the Indian Space Research Organisation (ISRO) is a significant step towards mastering in-space docking technology.
2. Far Rendezvous: The distance between the two spacecraft increases to 10-20 km.
3. Propulsion System: The Target spacecraft uses its propulsion system to stabilize the separation.
4. Progressive Approach: The Chaser satellite gradually reduces the distance in steps (5 km, 1.5 km, 500 m, 225 m, 15 m, and finally 3 m).
5. Docking: Once within 3 meters, the docking process Begins.
6. Power Transfer: After docking, electrical power transfer between the two satellites is demonstrated.
7. Undocking: The satellites undock and operate independently for up to two years.
This mission is crucial for India's future space ambitions, including the Gaganyaan manned mission and the Bharatiya Antariksh Station.
NASA has been a leader in docking technology since the Gemini program in the 1960s. They continue to use docking technology for the International Space Station (ISS). Roscosmos (Russia) has a long history of expertise in docking technology, dating back to the Soviet era. CNSA (China) or China National Space Administration (CNSA) has successfully demonstrated docking technology with its Shenzhou spacecraft.

Docking Process
1. Deployment: Both spacecraft are deployed simultaneously into orbit with a small relative velocity.2. Far Rendezvous: The distance between the two spacecraft increases to 10-20 km.
3. Propulsion System: The Target spacecraft uses its propulsion system to stabilize the separation.
4. Progressive Approach: The Chaser satellite gradually reduces the distance in steps (5 km, 1.5 km, 500 m, 225 m, 15 m, and finally 3 m).
