India will showcase its capabilities in autonomous satellite docking, a crucial technology for next space missions, through ISRO’s Space Docking Experiment (Spadex). Two 400 kg satellites, Chaser and Target, will be launched simultaneously on a Polar Satellite Launch Vehicle (PSLV) as part of the mission. The docking process is anticipated to take roughly ten days after the launch, which is set for December 30, 2024.
The main objective is to show that two spacecraft, the Chaser and the Target, can independently approach and dock with one another while in orbit. For many space operations, such as satellite maintenance and space station assembly, this intricate manoeuvre is essential.
Methods for preserving exact relative locations between the two satellites during flight will be validated by the mission. For space operations to be coordinated, this capability is essential.
One spacecraft will control its orientation using the Attitude Control System of the other while they are docked. This technology is crucial for ensuring stability and control during docking operations26.
Remote Robotic Arm Operations:
SpaDEX will also test remote robotic arm functionalities, which could be used for tasks such as repairs and maintenance of spacecraft in orbit..
This mission positions India alongside countries like the US, Russia, and China in mastering space docking technology, which is essential for various future missions including space station assembly and interplanetary exploration. The successful demonstration of these technologies could pave the way for ISRO’s ambitious plans, such as the Gaganyaan human spaceflight program and the proposed Bharatiya Antariksha Station.
