India’s space odyssey continues. All eyes have turned to Indian Space Research Organisation (ISRO) as it gears up for the Gaganyaan mission – the country’s first human spaceflight mission. And as prep for this upcoming mission, expected to be launched mid-2024, ISRO will be carrying out the Flight Test Vehicle Abort Mission-1 (TV-D1) on Saturday (21 October) at 8 am. This test, scheduled to be held from Sriharikota in Andhra Pradesh will demonstrate if the module in which the crew is housed can separate from the rest of the spacecraft and rocket in cases of emergency, and keep the astronauts inside safe. **Also read: Gaganyaan: How ISRO's astronauts are training hard for spaceflight** As the countdown to this test begins, here’s a behind the scenes look at what’s being done for the monumental journey.

The test will demonstrate the safety of the vehicle for the human space flight mission in future. The 21 October test will be followed by three more test vehicle missions, said ISRO chairman S Somanath.

The government has allocated an estimated budget of Rs 9000 crore for the Gaganyaan mission.

The only previous test flight of the crew module — called the Crew module Atmospheric Re-Entry Experiment or CARE — was carried out in 2014.

ISRO is developing environmental control and life support systems for the crew module, as well as an integrated vehicle health management system which can sense anomalies that could put the life of an astronaut at risk, and trigger actions to abort the mission.
