(JANUARY-2024)

ISRO to develop ECLSS for Gaganyaan mission after failing to get it from other countries.

Indian Space Research Organisation (ISRO) will develop the environmental control and life support system (ECLSS) indigenously for the Gaganyaan mission.

The Gaganyaan project aims to demonstrate India’s human spaceflight capability by launching a crew to a 400 km orbit and safely returning them to Earth.
The LVM-3, India’s heaviest rocket, will be used to launch Gaganyaan Mission. It is expected to be launched in 2025.
ISRO initially hoped to acquire the ECLSS from other countries but was unsuccessful.

The Environmental Control and Life Support System (ECLSS) is a subsystem typical of crewed space vehicles which provides all the necessary conditions in order to make life in space possible.
