Bridging the gap between the realms of robotics and human exploration, India is making significant strides in its ambitious human spaceflight program. Aiming to dispatch three astronauts to low Earth orbit (LEO) by the end of 2024, the nation is primed to undertake its first high-altitude abort test to validate the crew escape system for the upcoming Gaganyaan astronaut mission. Officials at the Indian Space Research Organisation (ISRO) have hinted at a potential launch window in early October or November.

The Test Vehicle Demonstration 1 (TV-D1) will not only evaluate the crew escape system but will also conduct comprehensive tests on the drogue parachutes designed to stabilize and decelerate the spacecraft upon its reentry into Earth’s atmosphere. This mission, set to launch from India’s spaceport in Sriharikota, is the first in a series of uncrewed flights planned throughout 2024 to test key technologies crucial for the success of the Gaganyaan mission.

India’s Ambitious Gaganyaan Mission: A Leap Towards Human Spaceflight

After its successful robotic explorations of the sun and the moon, India is now setting sights on human spaceflight. The Indian Space Research Organisation (ISRO) is aiming to dispatch three astronauts to low Earth orbit (LEO) by the end of 2024. This mission is a leap towards India’s ambitious Gaganyaan astronaut mission.

Preparatory Steps for Launch

The first high-altitude abort test to validate the crew escape system for the Gaganyaan mission is expected to commence in early October or November, as per ISRO officials. This test, known as Test Vehicle Demonstration 1 (TV-D1), will also scrutinize the drogue parachutes, which are designed to stabilize and decelerate the spacecraft during reentry into Earth’s atmosphere.

The launch is planned from India’s spaceport in Sriharikota and will be followed by a couple of uncrewed flights in 2024. These flights aim to test essential technologies for the mission. The schedule for the first crewed mission, which will send three astronauts to LEO at an altitude of 250 miles for three days, will be decided based on these test missions.

Ensuring Safety for the Astronauts

The series of tests to validate the crew escape system was initiated in July 2018 with the first pad abort test. The purpose of this test was to ensure the crew module could safely detach from the launch vehicle in emergency situations.

The reconfigured 143-foot-tall Launch Vehicle Mark-3 (LVM3) rocket, ISRO’s vehicle of choice for the crewed flight next year, has recently received human safety certification. This is a significant milestone for the mission as it ensures the rocket is safe for human travel.

Astronauts’ Training and Technology Tests

From February 2020 to March 2021, four Indian astronauts were trained at Russia’s Gagarin Cosmonaut Training Center near Moscow in preparation for the crewed flight. Earlier this year, ISRO announced that it had resumed tests to perfect its technology and hardware for the human spaceflight program. These tests included successful recovery of a mock crew module from a closed pool and deploying ribbon-type drogue parachutes on a rocket-powered rail track sled.


India’s ambitious Gaganyaan mission represents a substantial advancement in the country’s space program. With its successful execution, India will join the elite club of nations capable of human spaceflight. The rigorous preparation, including safety tests and astronaut training, indicates a strong commitment to the mission’s success. As a science journalist, it’s exciting to witness these remarkable strides in space exploration, and I look forward to the successful launch of the Gaganyaan mission.
