“Inspiration caves in with success”, and it has for ISRO with the successful launch of PSLV-C44 flight mission – as an inspiration from that, the space agency is now planning to take the experiments to new levels with plans to upgrade to better advanced space technologies in coming days.
ISRO plans to give the GSLV Mk III, a power upgrade to increase its payload capacity and boost up its efficiency for second Lunar mission – Chandrayaan 2, and other upcoming missions. For this, they will be using the highly refined form of furnace fuel, kerosene to boost the upper stage of GSLV Mk III rocket to increase the payload room. Taking about the improvements needed to up the 4 tons payload capacity to 6 tons, ISRO Chief Dr. K Sivan said that it begins with enhancements to load 30 tons of fuel in the cryogenic stage fuel loading, currently 25 tons – and December 2020 for the test of newly reformed Mk III rockets.
The second is to place semi-cryogenic engine, in place of the current L110 that carries highly refined ‘Kerolax’ with liquefied oxygen. The reformations in technology demand modifications at the second launch pad, the tender notice for which are already issued by Isro to invite quotations. Isro chief says negative for the use of the new for Gaganyan mission. The L110 staged GSLV Mk III is only to carry out manned missions, Isro chief clarifies. The 10 times dense Kerolox is more power generating and stable when compared to the same volume of hydrolox. This will help bring down expenses and save time.
The launch of heavy satellites weighing over 4 tons is backed by services of Arianespace, French Guiana. The same is to be used by India to launch the GSAT-31 communication satellite on February 6 and also GSAT-30 in June replacing INSAT-4A. March 2019 is also marked for the next PSLV-C45 mission carrying DRDO payload- ANISAT, says Dr. Sivan.
