Groundbreaking Spadex Mission Set for Launch
The Indian Space Research Organisation (ISRO) is poised to make waves in space exploration with its upcoming Spadex mission, scheduled for liftoff at 9:58 PM on December 30 from the renowned Sriharikota spaceport. This ambitious mission features two vital satellites—SDX01 (Chaser) and SDX02 (Target)—designed to pioneer satellite docking technology in orbit.
In a carefully orchestrated maneuver, the Polar Satellite Launch Vehicle (PSLV-C60) will deploy the two 220-kg satellites into a stable 470-km circular orbit. Initially, the satellites will separate by 10-20 km, utilizing precise adjustments in relative velocity. The Target satellite will then employ its propulsion system to maintain this distance, marking the initiation of what is known as the “far rendezvous.” From here, the Chaser satellite will progressively close the gap until a successful docking is achieved.
Once the satellites are docked, a series of experiments will commence, including the transfer of electrical power and coordinated control of both spacecraft. Following their separation after successful docking, the satellites will activate their respective payloads, designed to operate effectively for two years.
Cutting-edge technologies, such as sophisticated docking mechanisms and advanced sensors, underpin this mission. The Chaser will be outfitted with a high-resolution surveillance camera, while the Target will feature a multispectral payload aimed at monitoring vital resources. Additionally, the mission’s final rocket stage will conduct experiments involving a robotic arm and research on plant growth, showcasing the future of satellite collaboration.
