ISRO SpaDeX Docking Mission

Context

The Indian Space Research Organisation (Isro) aborted docking the two satellites (Chaser and Target), part of the Space Docking Experiment (SpaDeX) docking, marking the third postponement of this crucial mission

What is Docking?

Docking in space refers to the process of bringing two spacecraft together while in orbit, so that they can connect and operate as a single unit.
This process is especially critical for missions where separate modules or spacecraft need to be joined in space to complete a task.
This technology is essential for a variety of advanced space missions, including:
- Human spaceflight missions, such as sending humans to the Moon and later bringing lunar samples back to Earth.
- Building and operating a space station, such as India’s planned Bharatiya Antariksh Station.
- Satellite servicing missions, where one spacecraft can dock with another to perform maintenance or refueling.
Currently, only three countries— the United States, Russia, and China— have successfully demonstrated the ability to dock spacecraft in space.
For ISRO, mastering this technology is essential for future missions, including its planned human spaceflight missions and its goal of returning lunar samples from the Moon.

Fact Box:

SpaDeX Mission

The SpaDeX mission is a technology demonstrator that aims to showcase ISRO's capability to perform in-space docking.
This involves bringing two satellites together while in orbit, a complex operation that requires precise control and alignment.
This mission is an important step as ISRO moves towards developing the technology required for future space missions, including more advanced and ambitious projects.
Key Details of the SpaDeX Mission:
- Primary Payloads: The mission involves two spacecraft—SDX01 (Chaser) and SDX02 (Target)—that will be launched into an orbit 5 km apart.
- Mission Process: Over the course of 10 to 14 days, ISRO scientists will attempt to bring the two spacecraft closer to a distance of just 3 meters before they dock at an altitude of 470 km above Earth.
- Payloads on the Spacecraft:
  - SDX01 (Chaser) carries a High Resolution Camera.
  - SDX02 (Target) includes a Miniature Multispectral Payload and a Radiation Monitor Payload. These payloads will help in capturing high-resolution images and monitoring natural resources and vegetation.
- Launch Vehicle: The PSLV-C60 is the rocket carrying the SpaDeX mission. It will also carry 24 secondary payloads in addition to the two primary spacecraft.
