Get ready for some seriously cool space news, ENTECH readers! India is about to make history with its SpaDeX mission, a technological feat that will propel the nation to the forefront of space docking technology. Moreover, it is launching on 30th December 2024 at 21:58 hrs IST from SDSC SHAR, Sriharikota, this mission promises to be a thrilling spectacle.
What is the Experiment?
SpaDeX or space docking isn’t just another space mission; it’s a technology demonstrator. It aims to showcase India’s prowess in in-space docking – the ability to connect two spacecraft in orbit.
Imagine two satellites, the Chaser and the Target, meeting and joining in space – that’s SpaDEX! The Indian Space Research Organisation (ISRO) will use the PSLV-C60 rocket to send them into orbit. Therefore, the mission will demonstrate in-space docking technology, a crucial step for future ambitious projects. Further, successfully achieving this will make India only the fourth country globally to master this complex technology.
Key Objectives
The primary goal? To demonstrate the rendezvous, docking, and undocking of two small spacecraft (SDX01 and SDX02). Furthermore, the mission will test power transfer between the docked spacecraft and demonstrate composite spacecraft control and payload operations after undocking. This is a massive step towards more complex space operations.
The Mission Concept of SpaDeX
Two spacecraft, each weighing around 220 kg, will be launched simultaneously by PSLV-C60 into a 470 km orbit. Also, using precise launch capabilities, the spacecraft will initially separate, then using their own propulsion systems, carefully manoeuvre to meet, dock, and then undock. The whole process is planned to be fully autonomous, showcasing a high level of sophistication.
Innovative Technology In Space Docking
SpaDeX is packed with cutting-edge, indigenously developed technology. Moreover, this includes a unique docking mechanism, a sophisticated sensor suite for precise navigation, advanced power transfer technology, and a clever autonomous rendezvous and docking strategy. These advancements are a testament to India’s engineering expertise and innovation.
Further, the mission will also utilize a novel Relative Orbit Determination and Propagation (RODP) processor, which uses the Global Navigation Satellite System (GNSS) for precise positioning and navigation. All these technological advancements make SpaDeX a truly remarkable mission.
