Gaganyaan-1 (from Sanskrit: gagana, "celestial" and yāna, "craft, vehicle") will be the first uncrewed test flight of the Gaganyaan programme, with launch planned for December 2024.

Background

[edit]

The launch was originally scheduled for December 2020,[1] then in December 2021,[2] but it was delayed due to the COVID-19 pandemic.[1] The flight plan was finally ready by April 2022[3] and the launch is expected to take place in 2024,[4] after the TV-D1, TV-D2, TV-D3 and TV-D4.[5] It was proposed in April 2022 that the crew module should be depressurized,[6] something kept in the final planning.[7]

The first orbiter module adaptor assembly (OMA) was supplied by Kineco Kaman Composites on 23 December 2023. The OMA is a conical structure with a diameter of 4 meters, composed of carbon-fiber-reinforced polymers. It is combined with the equipment bay shroud and crew escape module.[8] With the successful qualification of the rocket's engines in February 2024,[9] the mission is scheduled for December 2024.[4][10]

Mission objectives

[edit]

The Gaganyaan spacecraft will be launched, with the humanoid robot Vyommitra, by a Human-rated LVM 3 from Satish Dhawan Space Centre and inserted into a 170 x 408 km orbit.[11][12] The circularisation maneuver will be performed at the third orbit. The landing should follow the same pattern as the TV-D1.[3][13]

After this mission, ISRO will perform four more abort tests before launching Gaganyaan 2,[5] carrying the humanoid robot Vyommitra,[14] which was later decided that it will also fly on G-1.[15].

Mission History

[edit]

The flight is planned in December 2024. The L110 stage for the upgraded LVM3 vehicle arrived at Satish Dhawan Space Center in July, followed by the S200 boosters. A Different Upper stage, the C-32, will be used in lieu of the C-25 for this mission. The C-32 is currently undergoing tests for the flight.[16]

The Abort motors have also arrived at SDSC . The Crew module is in the integration — propulsion and mechanical systems testing phase at the Vikram Sarabhai Space Centre (VSSC) and the service module wiring is going on at URSC.G1 will carry Vyomitra, and also an unpressurized engineering model of the Environmental Control and Life Support System (ECLSS) system.[16]
