The human-rated LVM3 stands 53 metres tall and is stacked at SDSC-SHAR
Background
ISRO records that the launch campaign for the first un-crewed Gaganyaan mission began with the stacking of the human-rated LVM3, christened HLVM3, at SDSC-SHAR, with the stacking of the nozzle end segment of the S200 motor.
HLVM3 is derived from LVM3 and designed with enhanced reliability for human safety; it is a three-stage vehicle with a payload capacity of about 10 tonnes to Low Earth Orbit, is 53 meters tall and weighs 640 tonnes.
A Crew Escape System is implemented to ensure crew safety by safe ejection of the Crew Module in a potentially adverse situation, and it is operational from the launch pad till its separation after the atmospheric flight regime.
The page recalls the LVM3-X/CARE mission, in which LVM3-X lifted a Crew Module of mass 3775 kg into a suborbital altitude of 126 km, after which the Indian Coast Guard recovered the module from the Bay of Bengal approximately 1600 km from SDSC-SHAR.
The L110 and C32 stages for HLVM3 were ready at the launch complex and the Crew Escape System elements had been received at SDSC, while the integration of the Crew Module was under way at VSSC and that of the Service Module at URSC.
In plain words
CES Crew Escape System — The system that ejects the Crew Module to safety from the launch pad until it separates after atmospheric flight.
SDSC SHAR Satish Dhawan Space Centre, Sriharikota — ISRO's launch centre on Sriharikota island in Andhra Pradesh, from which its orbital launches fly.
