India successfully fires heaviest launch vehicle

The Indian Space Research Organisation (ISRO) successfully launched its heaviest launch vehicle, GSLV MkIII-D1, and placed the country’s heaviest satellite till date, GSAT-19, into a precise orbit.

  • This was the first orbital mission of GSLV MkIII which was mainly intended to evaluate the vehicle performance including that of its fully indigenous cryogenic upper stage during the flight.
  • Weighing 3136 kg at lift-off, GSAT-19 is the heaviest satellite launched.

ISRO’s GSLV-Mk III

  • GSKV-Mk III  is capable of launching four-tonne satellites in the Geosynchronous Transfer Orbit (GTO).
  • The rocket is also capable of placing up to eight tonnes in a Low Earth Orbit (LEO), enough to carry a manned module.
  • GSLV-Mk III is a three-stage vehicle with two solid motor strap-ons (S200), a liquid propellant core stage (L110) and a cryogenic stage (C-25).
  • It is the first fully functional rocket to be tested with a cryogenic engine.

GSAT-19

  • GSAT-19 satellite developed to help improve telecommunication and broadcasting areas.gsat 19
  • GSAT-19 satellite with a lift-off mass of 3136 kg.
  • It carries Ka/Ku-band high throughput communication transponders and Geostationary Radiation Spectrometer (GRASP) payload to monitor and study the nature of charged particles and the influence of space radiation on satellites and their electronic components.

Tallest bridge across Chenab

Importance of the Bridge

  • World’s tallest railway arch bridge over the Chenab river in Jammu, providing rail connectivity to Kashmir.
  • It will be capable of handling high intensity blasts and resisting the worst possible natural disaster.
  • This is for the first time globally that a bridge is designed to handle high level trinitrotoluene (TNT) blast load.

About the Project

  • The bridge will be a crucial link in the 111-km stretch between Katra (Jammu) and Banihal (Kashmir) which is part of the Udhampur-Srinagar-Baramulla.
  • The railway project aimed at linking Kashmir through rail with the rest of the country.Rail chenab
  • The 1.3 km long bridge over the Chenab at a height of 359 metres will be 35m taller than the Eiffel Tower in Paris and five times the height of the Qutab Minar in Delhi.
  • The project site located at 60 km from the Pakistan border.
  • The construction work of the Chenab Bridge declared as a national project  in August 2004.
