// ORBITAL LOGISTICS AND PROPULSION TERM
Booster
A booster is a powerful first-stage rocket or an additional solid rocket motor that provides extra thrust during the initial part of a launch.

TECHNICAL DEFINITION
A booster is a primary or auxiliary rocket stage designed to provide initial high-thrust propulsion to a launch vehicle, overcoming gravitational forces and atmospheric drag during the ascent phase, often separating after its fuel is expended to reduce vehicle mass.
BACKGROUND
Skyroot Aerospace Private Limited is an Indian private aerospace manufacturer and commercial launch service provider headquartered in Hyderabad, Telangana. The company was founded by two former ISRO scientists, Pawan Kumar Chandana, and Naga Bharath Daka.
