ISRO’s SpaDeX Mission: India’s Leap Into Elite Global Space Club
The Indian Space Research Organisation (ISRO) is set to conclude 2024 with a groundbreaking mission, ISRO SpaDeX (Space Docking Experiment), scheduled for launch on December 30 at 9:58 PM IST from the Satish Dhawan Space Centre, Sriharikota. With this mission, India aims to become the fourth country—after the United States, Russia, and China—to master the complex technology of docking two spacecraft in orbit.

This technological feat is critical for future manned missions, in-orbit refueling, and assembling large structures in space, including space stations.
The Challenge of Space Docking
Docking is one of the most intricate operations in space. It involves two spacecraft coming together at high speeds to lock securely. Any error during this maneuver can lead to catastrophic outcomes, as highlighted in the famous movie Interstellar. ISRO’s SpaDeX mission will test this procedure using two spacecraft: the Chaser (SDX01) and the Target (SDX02), each weighing 220 kilograms.
Once in orbit at approximately 470 kilometers above Earth, the spacecraft will separate and drift 20 kilometers apart over 24 hours. Scientists at ISRO’s Bengaluru mission control will then initiate the precise docking and undocking operations.

Mission Details and Objectives
ISRO SpaDeX will be launched aboard ISRO’s reliable PSLV-C60 rocket. The primary objectives include:
- Demonstrating Docking Technology: Developing and executing rendezvous, docking, and undocking procedures for small spacecraft.
- Power Transfer Demonstration: Testing electric power transfer between docked spacecraft, crucial for in-space robotics.
- Remote Composite Control: Managing the spacecraft remotely from Earth and autonomously in orbit.
- Payload Operations Post-Undocking: Ensuring seamless functionality of spacecraft after separation.
If successful, SpaDeX will pave the way for India’s own space station and enhance the docking capabilities of India’s Reusable Launch Vehicle (RLV), akin to NASA’s space shuttles.
Both NASA and Russia’s Roscosmos have used docking mechanisms extensively to build the International Space Station (ISS). The United States employed its iconic Space Shuttles, including Columbia, Discovery, and Atlantis, while Russia deployed its Buran shuttle. These docking technologies remain integral to space exploration and research.
Microgravity Experiments with POEM-4
In addition to docking, ISRO will utilize the fourth stage of the PSLV rocket, termed POEM-4 (PSLV Orbital Experimental Module 4), as a platform for microgravity experiments. This stage, which would otherwise become space debris, will host 24 payloads for up to three months.
These payloads include contributions from ISRO, academic institutions, and start-ups. Notably, one payload involves testing a robotic arm for capturing tethered debris—a precursor to constructing India’s space station.
A New Era
ISRO SpaDeX represents more than just a technological milestone; it symbolizes India’s growing ambitions in space exploration. From advancing microgravity research to demonstrating robotic capabilities, this mission showcases ISRO’s readiness for the challenges of building a space station and conducting manned missions.
As the world welcomes the New Year, ISRO’s scientists are gearing up for a launch that could propel India into a new era of space innovation.
