Background
History & Context
What Changed
- ▶
BEFORE: ISRO satellites operated completely independently, lacking the ability to physically connect or share resources once in orbit. NOW: ISRO spacecraft can rendezvous autonomously, mechanically link, and transfer power and control data seamlessly in orbit.
- ▶
BEFORE: India relied entirely on the payload capacity of a single launch vehicle to send mass into deep space. NOW: With docking capabilities, ISRO can launch heavy mission components across multiple rockets and assemble them in orbit, a necessity for Chandrayaan-4.
- ▶
BEFORE: Only the US, Russia, and China possessed operational orbital docking technologies. NOW: India joins this elite group by successfully demonstrating its indigenous 'Bharatiya Docking System' with autonomous built-in intelligence.
