Odisha, February 2: Indian Space Research Organization ISRO has always placed India on the global level.  Development beyond Earth too matters as soon the technology is going to turn over the present developing phase. ISRO has always stood beyond the lines of possibilities to prove itself. To boost up the capacity of launch, ISRO is under the process of exploring the possibility of involving Indian industry in vital role in production of integrated systems.

Currently India has 39 operational satellites. From which 17 of them are of Earth observation, 13 are for communication, 7 are navigational and the rest 2 are space science satellites. ISRO is planning to build up and nurture the industrial capabilities so that the requirements meet the demands of launching the satellites. The satellites which are designed are utilized in the area of natural resources management, enabling weather forecasting, navigation, infrastructure planning, and disaster management support and satellite communication. Also, two communication satellites are planned to be launched from abroad onboard the Ariane 5 launcher. In coming two years the spacecrafts using Indian launch vehicles which includes four communication satellites, seven earth observation satellites, one navigation satellite and one space science satellite are supposed to be launched.

Like how TeamIndus is one the Indian privately owned space firm is stepping ahead likewise ISRO is making efforts to foster participation of Indian industries for manufacturing of space related hardware. Rocket engines, propellant tanks, spacecraft structures, electronic packages, thermal control systems, solar panels and other launch vehicles will be enhanced and used n ISRO. ISRO has launched many missions like Chandrayan, Atrosat etc and has all the facilities which are required for launching satellites. The list of facilities is as follows:

  • Two operational satellite launch pads,
  • Filling Control Centre (FCC) for propellant filling operations and
  • Mission Control Centre (MCC) & Launch Control Centre (LCC) for coordinating and
  • Conducting the launch operations during the countdown phase till the injection of the satellite into orbit

Last week the ISRO test fired the cryogenic engine in order to boost the technology. Likewise the project for the development of ‘semicryogenic’ engine has been approved and is under development. Following are the activities carried out for the development of semicryogenic engine:

  • Indigenous realization of 35 materials and 22 coating processes
  • Qualification of indigenous bearings for turbo pumps
  • Fabrication of the first hardware for three engine subsystems including low pressure turbo pumps and one high pressure turbo pump through industry
  • Design validation of the low pressure turbo pumps through cold flow trials.

If the semicryogenic engine develops and qualifies successfully; it will lead to its booster stage. An advanced space launcher that can deliver ten-tonne and heavier communication satellites to space requires a booster stage with clustered Semicryogenic engines.
