Introduction to SpaDeX Mission
The Indian Space Research Organisation (Isro) launched the Space Docking Experiment (SpaDeX) mission on December 30, 2024, with the goal of demonstrating technologies required to bring two satellites together in orbit, dock them, separate them, and transfer electrical power between them.
The mission consisted of two satellites, SDX01 and SDX02, each weighing approximately 220 kg. The spacecraft were designed to demonstrate autonomous docking and power transfer capabilities, which are essential for future missions that require spacecraft to join up in orbit.
Background and Objectives
The SpaDeX mission was conceived to address the growing need for advanced space technologies that can facilitate complex orbital operations. With the increasing number of satellites being launched into space, the ability to dock and transfer power between them has become a critical requirement for future space missions.
The primary objective of the SpaDeX mission was to demonstrate the technological capabilities required for autonomous docking and power transfer in space. The mission aimed to achieve this objective by launching two satellites into space and demonstrating their ability to dock, separate, and transfer power between them.
Key Achievements of SpaDeX Mission
Isro achieved the mission's first docking on January 16, 2025, followed by undocking on March 13. On April 20, the satellites completed a second docking, this time autonomously from a distance of 15 metres.
The space agency also demonstrated power transfer between the spacecraft a day later, with electricity from one satellite powering a heater on the other. These capabilities are crucial for future missions, including Chandrayaan-4, India's planned lunar sample-return mission, and the proposed Bharatiya Antariksh Station.
Technological Significance
The SpaDeX mission has established India's capability to demonstrate autonomous docking and power transfer in space, making it only the fourth country to achieve this feat.
The technology developed during this mission could also support future human spaceflight missions involving complex orbital operations. The mission's success has significant implications for the development of India's space program and its future missions.
Re-entry of SpaDeX Satellites
The SpaDeX satellites re-entered Earth's atmosphere on October 12 and 13, marking the end of the mission. According to Space-Track, a US Space Force catalogue of space objects, SDX01 re-entered at 9:38 pm on October 12 over the southern Indian Ocean, west of Australia, while SDX02 followed at 4:35 am on October 13 over the North Pacific, south of the Aleutian Islands.
The satellites' eventual return was preceded by a sustained decline in their orbital altitude. After undocking, they orbited at around 460 km above Earth, with their mean altitude dropping to approximately 413 km by January 1, 2026, and to 312 km by September 1.
