SpaDeX Mission

SpaDeX Mission Latest News

The Indian Space Research Organisation (Isro) has successfully completed the undocking of two satellites, part of the Space Docking Experiment (SpaDeX) mission, marking a significant milestone in India's space exploration journey.

About SpaDeX Mission

• SpaDeX mission is a cost-effective technology demonstrator mission for the demonstration of in-space docking using two small spacecraft launched by PSLV.
• The primary objective of the SpaDeX mission is to develop and demonstrate the technology needed for rendezvous, docking, and undocking of two small spacecraft (SDX01, which is the Chaser, and SDX02, the Target, nominally) in a low-Earth circular orbit. Secondary objectives include:
  • Demonstration of the transfer of electric power between the docked spacecraft, which is essential for future applications such as in-space robotics,
  • Composite spacecraft control, and
  • Payload operations after undocking.
• The SpaDeX mission consists of two small spacecraft (about 220 kg each) launched by PSLV-C60.
• Recent Developments:
  • The SPADEX satellites were successfully docked recently. ISRO has now accomplished the pivotal operation of undocking of SPADEX satellites in the very first attempt on 13th March, 2025. 
  • The undocking of the satellites took place in 460 km circular orbit with 45-degree inclination. 
  • The satellites are now orbiting independently and their health is normal. 
  • With this, ISRO has now successfully demonstrated all the capabilities required for rendezvous, docking and undocking operations in a circular orbit.
• Significance:
  • This accomplishment made India the fourth country after USA, Russia and China in the world to achieve the feat.
  • SpaDEx mission is expected to be a stepping stone for India’s future endeavours in space exploration which include getting rocks and soil from the moon on Earth, the proposed Bharatiya Antariksha Station and landing an astronaut on the lunar surface.

What is ISRO?

• Founded in 1969, the Indian Space Research Organisation (ISRO) is the space agency of India, responsible for the planning and execution of space-related activities in the country. 
• ISRO is one of the most prominent and successful space agencies in the world, known for its cost-effective and efficient space missions. 
• ISRO operates under the Department of Space, which reports directly to the Prime Minister of India. The department primarily executes the Indian Space Programme through various ISRO Centres.
