ISRO to launch SpaDeX mission today, a major leap in spacecraft docking technology: Know the timing and location

New Delhi (The Uttam Hindu): The Indian Space Research Organisation (ISRO) is set to launch its "Space Docking Experiment" (SpaDeX) mission on December 30, 2024, at 10:00:15 PM IST from the Satish Dhawan Space Centre in Sriharikota. This mission aims to develop and demonstrate technology for the rendezvous and docking of two small spacecraft, designated as SDX01 (Chaser) and SDX02 (Target), each weighing approximately 220 kg. The satellites will be placed in a 470 km low-Earth circular orbit with a 55° inclination.

The primary objectives of the SpaDeX mission include demonstrating precision maneuvers for docking, validating the transfer of electrical power between docked spacecraft, and operating payloads post-undocking. This mission is particularly significant as it lays the groundwork for future lunar missions, such as Chandrayaan-4, by testing capabilities needed for autonomous docking without relying on GNSS support from Earth.

In addition to its docking objectives, SpaDeX will utilize the PSLV's spent fourth stage, known as POEM-4 (PSLV Orbital Experimental Module), as a platform for microgravity experiments. A total of 24 payloads from various academic institutions and startups will be carried on board. The SpaDeX mission is seen as a crucial step for India in advancing its space exploration ambitions. By mastering docking technology, India aims to position itself among the few countries that have achieved this capability, which is essential for missions requiring multiple launches to accomplish common objectives, such as satellite servicing and the assembly of complex structures like the proposed Bharatiya Antariksh Station (BAS). Overall, the SpaDeX mission represents a significant milestone in India's space endeavors, showcasing its expertise in spacecraft docking technology and paving the way for future interplanetary missions and human spaceflight.
