The Indian Space Agency’s (ISRO) Geosynchronous Satellite Launch Vehicle (GSLV) was previously known as the “naughty boy” because of its spotty success rate. After successfully launching INSAT-3DS on February 17, 2024, the GSLV earned the new moniker “smarty boy”

The GSLV’s cryogenic engine uses liquid hydrogen as the main fuel. Hydrogen is a very efficient rocket fuel, but it’s difficult to handle in its natural gaseous form. 

The CE20 cryogenic engine, which powers the cryogenic stage of the human-rated LVM3 launch vehicle for Gaganyaan missions, also recently achieved a major milestone

This collaboration will use ISRO’s GSLVF14 rocket, historically nicknamed the “naughty boy” but now referred to as the “smart boy” after its successful launch of INSAT-3DS on 17 February

The CE-20 cryogenic rocket engine was developed by the Liquid Propulsion Systems Centre (LPSC), a subsidiary of ISRO. The development of the CE-20 is a collaborative effort between the following institutions: 

• Liquid Propulsion Systems Center 
• Vikram Sarabhai Space Centre 
• Isro Propulsion Complex 
• Satish Dhawan Space Centre

In 1987, V Gnanagandhi, the head of ISRO’s cryogenic engine project, wanted to establish a high-pressure hydrogen plant in Mahendragiri near Thiruvanathapuram

The CE-20 is a cryogenic rocket engine developed by the Liquid Propulsion Systems Centre (LPSC), a subsidiary of the Indian Space Research Organisation (ISRO).

The CE-20 cryogenic engine was used in the Chandrayaan-3 mission. The CE-20 is India’s largest cryogenic engine and has been used in six LVM-3 missions since 2017, including the Chandrayaan-2 mission in 2019 and the Chandrayaan-3 mission in 2023

The CE-20 burns liquid hydrogen and liquid oxygen for up to 800 seconds. It’s powered by a gas generator cycle and uses a combination of LOX and LH2 propellants

The Liquid Propulsion Systems Centre (LPSC) is a subsidiary of ISRO that designs and develops the CE-20 cryogenic engine. The LPSC is at the forefront of developing liquid and cryogenic propulsion stages for launch vehicles and auxiliary propulsion systems for both launch vehicles and satellites

Quoting INSAT-3DS Mission Director Tomy Joseph, the report said the naughty boy has matured as a very obedient and disciplined boy, and has become a robust vehicle for ISRO similar to PSLV. According to the report, Vikram Sarabhai Space Centre Director S Unnikrishnan Nair coined the terms “smarty” and “natty” for GSLV.18 Feb 2024

The successful orbiting of India’s third generation weather satellite INSAT-3DS in a copybook style on Saturday has enhanced the confidence about the Geosynchronous Satellite Launch Vehicle (GSLV) rocket for the next prestigious launch, said officials of Indian space agency. The GSLV rocket (formerly GSLV-MkII) had earned the nickname ‘naughty boy’ during its initial days for its inconsistent performance.

Cryogenic engines will make India a bigger player in the global satellite manufacture and launch market. This alone is worth about $25 billion. In totality, the satellite based aerospace economy including the data it garners, and the content it delivers is worth close to $200 billion.

Global telecom, news and entertainment all depend on satellites picking up radio signals and bouncing them around the Earth’s curvature. In consumer terms, Zomato and Swiggy depend on location services from satellites and the news you watch comes via satellite.
