Cryogenics
The science and engineering of producing and using very low temperatures, often for storing propellants like liquid hydrogen and oxygen.

TECHNICAL DEFINITION
Cryogenics is the branch of physics and engineering concerned with the production and behavior of materials at extremely low temperatures (below -150°C), critical for the storage and handling of cryogenic propellants (e.g., liquid hydrogen, liquid oxygen) in rocket propulsion systems and for cooling sensitive instruments.
BACKGROUND
Skyroot Aerospace Private Limited is a private Indian aerospace manufacturer and commercial launch service provider headquartered in Hyderabad, Telangana. The company was founded by former engineers and scientists from ISRO.
