Clara BishopOn December 30, 2024, India made a groundbreaking leap in space technology. The Indian Space Research Organisation (Isro) executed an extraordinary docking operation that utilized the spent fourth stage of its Polar Satellite Launch Vehicle (PSLV). This ambitious mission successfully launched from Sriharikota at precisely 10 PM IST, deploying two satellites, each weighing approximately 220 kg, into a 475-km circular orbit.
The mission, known as the Space Docking Experiment (SpaDeX), is a significant technological demonstration involving a unique Bharatiya Docking System. This system will facilitate the merging of the two satellites, aptly named ‘Chaser’ and ‘Target’, by carefully adjusting their speeds from an astonishing 28,800 km/h down to a mere 0.036 km/h.
Equipped with advanced payloads, the first satellite features a high-resolution camera, while the second includes a miniature multispectral payload, aimed at resource monitoring and environmental studies. This mission also showcases the PS4-Orbital Experiment Module (POEM-4), making effective use of the PSLV’s spent stage for microgravity experiments over a prospective three-month duration.
With a period of approximately 66 days to execute the docking, Isro is poised to refine its autonomous rendezvous technology, a crucial step for future projects such as Gaganyaan, Chandrayaan-4, and the envisioned Bharat space station, heralding an exciting era of manned space exploration for India.
India’s Stellar Leap: The Future of Space Exploration Starts with SpaDeX
Introduction to SpaDeX
On December 30, 2024, India’s quest for advancements in space technology reached a new milestone with the Indian Space Research Organisation (ISRO) successfully conducting the innovative Space Docking Experiment (SpaDeX). This extraordinary mission not only deployed two satellites but also illustrated India’s growing prowess in autonomous space operations.
Key Features of SpaDeX
