SPADEX or Space Docking Experiment is a twin spacecraft mission being developed by Indian Space Research Organisation to mature technologies related to orbital rendezvous, docking, formation flying and remote robotic arm operations, with scope of applications in human spaceflight, in-space satellite servicing and other proximity operations.[1]

SPADEX campaign would consist of two IMS-2 class (400 kg) satellites, one would be Chaser and other being Target and both would be launched as co-passengers or auxiliary payloads.[2] Both spacecraft would be injected into slightly different orbits.[3]

Space Docking Experiment is currently scheduled for launch from Satish Dhawan Space Centre aboard a Polar Satellite launch Vehicle.[4][5][6]

Objectives

  • Autonomous rendezvous and docking
  • Controlling one spacecraft with Attitude Control System of other spacecraft while in docked configuration.[1]
  • Formation flying
  • Remote robotic arm operations[citation needed]

Status

With preliminary studies done in 2016,[7] Space Docking Experiment was approved by Government of India with initial funding of ₹10 crore cleared in 2017.[8] In June 2019, ISRO was looking for proposals to study remote robotic arm operation, rendezvous and docking related technologies on its PSLV fourth stage (PS4) orbital platform.[9]
