ISRO successfully ground-tests Cryogenic Upper Stage engine meant for rocket GSLV-Mark-III

Indian Space Research Organisation (ISRO) has successfully ground tested the Cryogenic Upper Stage engine meant for the rocket GSLV-Mark-III. In a release, the space agency has said the indegenously developed engine, designated as C25, was tested for a duration of 50 seconds in its Propulsion Complex at Mahendragiri in southern Tamil Nadu, demonstrating all the stage operations.

The performance of the Cryogenic Upper Stage during the test was as predicted. This is the first in a series of two tests. The next one is planned for a flight duration of 640 seconds shortly.

The national space agency has termed the 50 second test as a significant milestone in the development of indigenous cryogenic propulsion technology. It adds, the successful hot test in the first attempt itself demonstrates ISRO’s ability to work in such complex and new areas.

The GSLV-Mark-III rocket fitted with the cryogenic upper stage is expected to lift off in the first quarter of this year, carrying a 4-tonne class communication satellite.
