The 'Crew Module Uprighting System' (CMUS) in the Gaganyaan mission is primarily designed to:

Ensure the module remains upright after splashdown in the sea

Provide power and propulsion to the crew module during orbit

Protect the parachutes during the atmospheric re-entry phase

Facilitate the separation of the service module from the crew module

In the context of the Gaganyaan mission, what is the primary function of the 'apex cover'?

To protect parachutes and associated subsystems during the mission

To provide propulsion during the launch phase

To serve as the primary interface for the service module

To maintain the upright position of the module after landing

ISRO Gaganyaan system tests

Gaganyaan is a flagship national space mission, and specific technical milestones like system-level qualification tests are frequently asked in the context of India's advancements in space technology.

Notes

ISRO successfully conducted three major system-level qualification tests for the Gaganyaan crew module.
Crew Module Uprighting System (CMUS): A cold-gas-based system designed to ensure the crew module remains in an upright position after splashdown in the sea.
CMUS inflation test: Validated the primary inflation module using stored high-pressure gas to inflate floatation devices via control valves.
Umbilical Mechanism Separation: Tested the separation of the CSU-2 mechanism (Service Module side) from the crew module to ensure clean detachment during re-entry.
The umbilical mechanism consists of CSU-1 (Crew Module side) and CSU-2 (Service Module side), facilitating power and propulsion links.
Apex Cover Separation: Validated the structural integrity of the crew module during the separation of the apex cover, which protects parachutes and associated subsystems before deployment.

Part of a longer story

This is day 2 of 2 in ISRO Gaganyaan mission qualification and system testing, which has been running since 6 July 2026. Reading it whole is usually worth more than reading today alone — the exam asks how something developed.
