Bengaluru, Nov 20: The Indian Space Research Organisation will launch PSLV-C54/ EOS-06 mission with Oceansat-3 and eight nano satellites, including one from Bhutan, on board from Sriharikota spaceport on November 26.

The launch is scheduled at 11.56 am (rpt 11.56 am) on Saturday, said the national space agency headquartered here.

Asked about the passengers aboard the rocket, a senior ISRO official told PTI on Sunday: “EOS-06 (Oceansat-3) plus eight nano satellites (BhutanSat, ‘Anand’ from Pixxel, Thybolt two numbers from Dhruva Space, and Astrocast – four numbers from Spaceflight USA).

The Indian space agency is gearing up for launching the next set of 36 satellites of the UK-based Network Access Associated Ltd (OneWeb) in January 2023 by testing the crucial cryogenic engine of its rocket LVM3.

The orbiting of first set to 36 satellites happened successfully on Oct 23 from Sriharikota rocket port in Andhra Pradesh with LVM3 rocket also known as Geosynchronous Satellite Launch Vehicle MkIII (GSLV MkIII).

According to the Indian Space Research Organisation (ISRO), the flight acceptance hot test of a CE-20 engine was successfully carried out for a duration of 25 seconds in the High Altitude Test facility of ISRO Propulsion Complex at Mahendragiri.

This engine is earmarked for the LVM3-M3 mission identified for the launch of the next set of 36 numbers of OneWeb India-1 satellites, ISRO said.

The cryogenic upper stage of the LVM3 vehicle (C25 stage) is powered by a CE-20 engine working with liquid oxygen and liquid hydrogen (LOX-LH2) propellants combination. This engine develops a nominal thrust of 186.36 kN in vacuum.

The major objectives of the flight acceptance test were to confirm the integrity of the hardware, assessment of subsystems’ performance and tune the engine for meeting the mission requirements parameters for engine tuning for flight operation.
