2 satellites, one dock': ISRO’s SpaDeX Mission will revolutionize space travel today
The Indian Space Research Organisation (ISRO) is poised to conclude 2024 with a transformative advance in space exploration. On December 30, 2024, at exactly 9:58 PM IST, ISRO is scheduled to launch its eagerly awaited SpaDeX mission on the PSLV-C60. This initiative signifies a crucial turning point for India’s aspirations in space, highlighting the nation's inaugural demonstration of in-space docking technology featuring two small crafts.
The SpaDeX initiative consists of two satellites, SDX01 (the Chaser) and SDX02 (the Target), which are engineered to dock within low Earth orbit. This technological achievement is essential for India's future projects, including lunar missions and the establishment of a national space station. ISRO has assured that the PSLV-C60 is in readiness, with the launch vehicle fully assembled and transported to the First Launch Pad for concluding inspections.
The mission initiates with the deployment of the Target satellite 15 minutes following launch, soon to be followed by the Chaser. By employing precise incremental velocity modifications, the Target spacecraft will gradually separate from the Chaser by 10-20 km, creating the conditions for a series of methodical maneuvers. These maneuvers will involve systematic reductions in the distance between the satellites, culminating in docking—a milestone anticipated to take place in early January 2025.
ISRO characterizes SpaDeX as a landmark achievement in India’s endeavors in space, enhancing competencies in spacecraft rendezvous, docking, and undocking. These technologies are crucial for servicing satellites, managing space station operations, and undertaking interplanetary missions. As stated by ISRO, "SPADEX will act as a vital progression in enhancing India’s space docking capabilities, facilitating future missions that include astronauts, sample returns, and sophisticated space infrastructure."
Compounding the mission’s intricacy, the PSLV-C60 will also transport 24 payloads as a component of the PS4-Orbital Experiment Module (POEM-4). These payloads exemplify ISRO’s commitment to incorporating state-of-the-art research into operational missions, highlighting India’s swift advancement in space exploration.
