• ISRO to launch PSLV-C54/EOS-06 mission with Oceansat-3 and eight nano satellites from Sriharikota
Indian Space Research Organization will launch PSLV-C54/EOS-06 mission with Oceansat-3 and eight nano satellites from Sriharikota Space Center on November 26.
The launch is scheduled for 11.46 am on Saturday, the national space agency said. When asked about the passengers on board the rocket, a senior ISRO official said, "The mission will carry EOS-06 (OceanSat-3) plus eight nano satellites ('Anand' from BhutanSat, Pixel from Dhruv space, Thibault number two and Astrocast - contains four numbers from Spaceflight USA).
Separately, the Indian space agency's Vikram Sarabhai Space Center on Sunday conducted the Integrated Main Parachute Airdrop Test (IMAT) of its crew module deceleration system for the maiden Gaganyaan human space flight programme.
The parachute airdrop was conducted in Jhansi district of Uttar Pradesh.
The Gaganyaan deceleration system comprises three main parachutes, besides smaller ACS, pilot and drogue parachutes, to reduce the speed of the crew module to a safe level during landing, ISRO said in a statement.
Of the three main chutes, two are sufficient to land the astronauts on Earth, and the third is redundant, ISRO said, adding that the IMAT test simulated the case when one main chute failed to open. The IMAT test is the first in a series of integrated parachute airdrop tests to simulate various failure conditions of the parachute system to be qualified for use in the first manned spaceflight mission.
In this test, a five ton dummy mass equal to the crew module mass was carried to an altitude of 2.5 km and dropped using an IL-76 aircraft of the Indian Air Force. Two smaller pyro-based mortar-deployed pilot parachutes then towed the main parachutes.
""The fully inflated main parachute reduced the speed of the payload to a safe landing speed. The entire sequence lasted for about 2-3 minutes as the scientists watched with bated breath the various phases of the deployment sequence," ISRO said in a statement.
The design and development of the parachute-based deceleration system is a joint venture between ISRO and the Defense Research and Development Organization (DRDO).
