ISRO Undocks Satellites, Boosting Future Space Mission Capabilities

Why in the news ?

This title highlights ISRO’s achievement in undocking satellites, marking a technological leap for future missions like Chandrayaan-4 and the Bharatiya Antariksha Station. It emphasizes India’s growing expertise in space docking, crucial for lunar exploration and space station assembly.

ISRO Undocks Satellites, Boosting Future Space Mission Capabilities

About the Successful Undocking of Satellites:

  • On March 13, ISRO successfully undocked two satellites, SDX01 (Chaser) and SDX02 (Target), at 9:20 AM.
  • This follows India’s first docking demonstration nearly two months earlier.
  • The undocking process involved extending SDX02’s arm, releasing capture levers, and separating the satellites in orbit.
  • Both satellites are now moving independently in space.
  • India is now the fourth country after the US, Russia, and China to achieve this milestone.

Significance of Docking & Undocking Technology

  • This capability is crucial for upcoming missions like Chandrayaan-4, which aims to bring back Moon samples.
  • For the Bharatiya Antariksha Station, ISRO will use docking technology to assemble five modules in space.
  • The International Space Station (ISS) also relies on similar docking mechanisms for crew and cargo transport.
  • ISRO has also demonstrated power sharing and the ability to command both satellites as a single composite unit.

Future Plans and Developments

  • ISRO officials waited nearly two months after docking to ensure precise execution of the undocking.
  • More docking and undocking experiments will be conducted to refine precision and reliability.
  • Extensive ground simulations and tests ensured a successful first attempt at undocking.
  • Future missions, like Chandrayaan-4, will require multiple docking operations for sample transfer and return to Earth.
  • The docking system developed by ISRO will play a key role in India’s human spaceflight and space station programs.
