Adding more thrust

  1. The Vikas engine will improve the payload capability of PSLV, GSLV and GSLV Mk-III launch vehicles.
  2. The space agency has improved the thrust of the Vikas engine that powers all of them.

Main beneficiary: GSLV Mk III

  1. The main beneficiary of the high-thrust Vikas engine is said to be the heavy-lifting GSLV-Mark III launcher, which ISRO expects will now put 4,000-kg satellites to space.
  2. This would be the third Mk-III and the first working one to be designated Mk III Mission-1 or M1.
  3. The first MkIII of June 2017 started with a 3,200-kg satellite and the second one is being readied for lifting a 3,500-kg spacecraft.
  4. The Vikas engine is used in the second stage of the light lifting PSLV; the second stage and the four add-on stages of the medium-lift GSLV; and the twin-engine core liquid stage of Mk-III.

Soon to be replaced

  1. ISRO will phase out Vikas by replacing it first in Mk-III with a cleaner and safer semi-cryogenic engine.
  2. The semi-cryo engine is ready for trial; its stage has just been approved
