Gaganyaan is India’s first human spaceflight mission being developed by the Indian Space Research Organization (ISRO). The goal of the mission is to send a crew of three into low Earth orbit (LEO) for a period of up to seven days.
The Gaganyaan spacecraft is designed to carry three people, and the planned upgraded version will be equipped with rendezvous and docking capabilities.
On October 21, 2023, the Indian Space Research Organization (ISRO) was all set to launch the Demonstration Test Unmanned Vehicle (TV-D1) from the Satish Dhawan Space Center in Sriharikota. The launch was scheduled for 8:30 a.m., but with just five seconds left on the countdown clock, the rocket went into standby mode.
After a detailed analysis of the situation, the ISRO team was able to resolve the issue and TV-D1 was successfully launched at 10:00 AM. The mission was successful
The Gaganyaan mission is a significant milestone in India’s space programme. If successful, India will become the fourth country to send humans into space, after the Soviet Union (later Russia), the United States and China.

Gaganyaan Mission Objectives
- The primary objectives of the Gaganyaan mission are:
- Demonstrate India’s capability to undertake human spaceflight missions
- Gain experience in the design, development and operation of human spacecraft
- Develop the necessary infrastructure for sustainable human spaceflight activities
- Inspire the next generation of scientists and engineers

The Gaganyaan mission is currently scheduled for launch in 2024. The mission will consist of two unmanned test flights and one manned flight.
The first unmanned test flight, known as Gaganyaan-1, is planned for launch in 2023. The primary objective of Gaganyaan-1 is to test the systems and subsystems of the Gaganyaan spacecraft.
A second unmanned test flight, known as Gaganyaan-2, is planned for launch in 2024. The primary objective of Gaganyaan-2 is to test the re-entry and landing system of the Gaganyaan spacecraft.
The crewed flight, known as Gaganyaan-3, is planned for launch in 2024. The Gaganyaan-3 mission will carry a crew of three to LEO for up to seven days.
What is an Interrupt Test Mission?
Gaganyaan Mission: ISRO will begin unmanned flight tests for the Gaganyaan mission.
Preparations are underway for the Test Vehicle-1 (TV-D1) abort mission, which demonstrates the performance of the crew escape system.https://t.co/HSY0qfVDEH @indian navy #Gaganyaan pic.twitter.com/XszSDEqs7w

Today’s unmanned test flight had the main objective of demonstrating the capability of the Crew Escape System (CES) to safely separate the crew module from the launch vehicle in the event of an emergency.
At the predetermined ascent point, the abort scenario will be simulated and the CES will be activated. The CES will separate the crew module from the launch vehicle and deploy a series of parachutes to safely land the crew module in the Bay of Bengal.
The abort test mission is a vital step in the development of the Gaganyaan mission. Successful completion of the test will provide confidence that the CES is capable of safely protecting the crew in the event of an emergency.
Data collected from the test will also be used to refine the CES design and termination procedures.
