Indian Space Capabilities

[Nan Yang]

Can anybody tell me what is the propellant/mixture used in Indian boosters/rocket versus that used by other countries? Indian ones leave a trail of heavy smoke whereas when you see the latest launch by China, the one a few months ago by South Korea, etc., they emit a small blue flame (similar to kerosene stove) with a tadtadi sound.

Currently, India uses solids for its first stage and boosters thats why the smoke. China uses earth storeable liquids, so not that much smoke . SK uses semi cryo, blue flame and cleaner. Both India and china planing to swicth to semi cryos

GSLV-MK1 was launched in 2001 that had 1.5T payload capacity of GTO using russian cryo engines ,GSLV MK2 that has indian cryoengine had 1st unsuccessful flight in 2010.
GSLV-MK3 payload to GTO is 4T not 5T.

ISRO begins tests on indigenous Cryogenic Engine for the much awaited GSLV D5 Mission​

GSLV Mark II

The Indian Space Research Organisation (ISRO) has commenced testing the indigenously developed cryogenic engine, which has been mounted on the Geosynchronous Satellite Launch Vehicle (GSLV) — MK II.

Isro chairman K Radhakrishnan had announced earlier that the GSLV D5 mission, carrying GSAT-14, the communication satellite, would be launched on August 6 from the Satish Dhawan Space Centre at Sriharikota.

“Vehicle integration is going on at present. The cryogenic engine has been mounted on the launch vehicle, and elaborate checks are on,” Isro spokesperson Deviprasad Karnik said.

After a series of successful high-altitude tests at Isro's Liquid Propulsion Systems Centre (LPSC) in Thiruvananthapuram in the last few months, the engine was moved to Sriharikota, from where the GSLV will be launched.

The GSLV is a three-stage vehicle — the first stage has solid fuel, and the second stage is an engine carrying liquid propellant. The third stage, the indigenously built cryogenic upper stage, uses cryogenic propellants. According to senior Isro officials, the cryogenic stage enhances India's indigenous capability to launch communication satellites and other ambitious space missions.

This launch is crucial for India as the previous two GSLV missions in 2010 were unsuccessful. Of the two previous missions, one of the launch vehicles was fitted with the Indian cryogenic engine.

The cryo-powered GSLV rockets are important for the country's future space programmes like Chandrayaan-2. All the initial GSLV missions were fitted with cryogenic engines purchased from Russia. In 1992, when the United States pressured Russia to deny India the cryogenic technology, India decided to build the engine on its own.

Since then scientists at Isro have been working on developing an indigenous cryo engine, tested in a previous GSLV mission in 2010, which ended in failure.

Arianespace’s upcoming Ariane 5 launch set for July 26, 2013, INSAT 3D will be orbited along with European Space Agency's Alphasat satellite. INSAT 3D which has a mass at liftoff of approximately 2100 kg, is designed to provide enhanced meteorological observation and the monitoring of land / ocean surfaces. Also carried a data relay transponder, along with a system to assist in satellite aided search and rescue operations. INSAT 3D will be riding as the Ariane 5 mission’s lower payload, located under Alphasat inside the SYLDA dispenser system.
