The Indian Space Research Organisation (ISRO) is set to launch the PSLV-C60 mission tonight at precisely 10:00 PM IST. This mission marks a significant milestone as it includes the Space Docking Experiment (SpaDeX), aimed at demonstrating India’s capability in autonomous orbital docking—a critical technology for future human spaceflight and satellite servicing missions.
Mission Overview
The PSLV-C60 will carry two small satellites, each weighing approximately 220 kg, designated as SDX01 (Chaser) and SDX02 (Target). These satellites will be placed into a 470 km circular orbit, where they will perform a series of complex maneuvers to achieve docking. The mission is expected to last about ten days, culminating in the docking operation.
Significance of SpaDeX

The innovative mission SpaDeX aims to demonstrate India’s proficiency in orbital docking. Among the many uses for which this technology is crucial are:
- Future Human Spaceflight: Docking technology is crucial for assembling modules of a space station or transferring crew and supplies between spacecraft.
- Satellite Servicing: Enables in-orbit repair, refueling, or upgrading of satellites, extending their operational life.
- Formation Flying: Allows multiple satellites to operate in a coordinated manner, enhancing capabilities for Earth observation, astronomy, and other scientific missions.
Technological Innovations
The mission will test several indigenous technologies, including:
- Docking Mechanism: A low-impact, androgynous peripheral docking system designed for compatibility with various spacecraft configurations.
- Rendezvous Sensors: Advanced sensors to determine relative position and velocity during approach, ensuring precise maneuvering.
- Inter-Satellite Communication: VHF/UHF transceivers for data transfer and synchronization between the two satellites.
Challenges Ahead
Achieving successful docking in space is a complex task, especially given the small size and low inertia of the satellites involved. Even minor disruptions can affect alignment, necessitating extremely precise control systems. ISRO has developed sophisticated algorithms and conducted extensive ground simulations to address these challenges.
Future Implications
A successful SpaDeX mission will place India among a select group of nations with autonomous docking capabilities. This achievement will pave the way for more ambitious projects, such as the planned Bharatiya Antariksh Station (BAS) and collaborative international missions requiring in-orbit assembly and servicing.
