The Indian space agency successfully tested a cryogenic engine intended for the upper stage of its GSLV launch vehicle, clearing the way for the next GSLV launch later this year. ISRO tested the engine, powered by liquid hydrogen and liquid oxygen, in a test chamber designed to simulate the low pressure of the upper atmosphere. The test on Wednesday confirmed the performance of the engine, according to Indian officials. The engine will be used on the upper stage of the next Geosynchronous Satellite Launch Vehicle (GSLV), slated to lift off in the latter half of July carrying a communications satellite. A previous GSLV flight using an Indian-developed cryogenic upper stage engine failed in 2010 because of a problem with that engine.
