News: <\/span><\/b>Geosynchronous Satellite Launch Vehicle-Mark3 (GSLV-Mk3) which is India\u2019s heaviest rocket will enter into the commercial market after attempting to put 36 satellites in Low Earth Orbit (LEO) for UK-based OneWeb on <\/span>October.<\/span>\u00a0<\/span><\/p>\n

ISRO has already launched 345 foreign satellites using Polar Satellite Launch Vehicle (PSLV)<\/span>. <\/span>However, this time it will be GSLV that will launch the satellites.<\/span>\u00a0<\/span><\/p>\n

What is the importance of GSLV-Mk3 on the present mission?<\/span><\/b>\u00a0<\/span><\/h5>\n

GSLV-Mk3 first mission was the Crew Module Atmospheric Re-entry Experiment in 2014. However, it was declared operational in the year 2019 after the launch of Chandrayaan-2.<\/span>\u00a0<\/span><\/p>\n

It was also used in demonstration missions in 2017 and 2018 by launching Gsat-19 and Gsat-29.<\/span>\u00a0<\/span><\/p>\n

Therefore, from past experience, ISRO is confident in this mission as well. This mission will show India\u2019s ability to launch heavier payloads to LEO. <\/span>\u00a0<\/span><\/p>\n

It will also attract commercial customers through Space PSU New Space India Limited (NSIL) and provide future opportunities <\/span>for launches into higher orbits.<\/span>\u00a0<\/span><\/p>\n

There are also strategic benefits of a successful Mk3 such as launching a group of remote-sensing satellites in the future.<\/span>\u00a0<\/span><\/p>\n

However, the future lies in the development of rockets along with the increasing demands and India needs to address it.<\/span>\u00a0<\/span><\/p>\n

What are the current problems with rocket development in India and how can they be solved?<\/span><\/b>\u00a0<\/span><\/h5>\n

India is currently working with GSLV-Mk3 to launch third-party commercial satellites but simply relying on GSLV-Mk3 will not work. <\/span>\u00a0<\/span><\/p>\n

Rocket technology is developing rapidly and India also needs to move along with the global development if it wants to compete with the world leading space agencies.<\/span>\u00a0<\/span><\/p>\n

There is also a need to increase the payload of rockets<\/strong> as GSLV-Mk3 is currently the highest <\/span>payload capacity in India but it is at best only a medium-lift rocket by global standards.<\/span>\u00a0<\/span><\/p>\n

Moreover, India is taking efforts towards manufacturing GSLV-Mk3 to be in the line of competition as NSIL is looking to manufacture more launch rockets (GSLV-Mk3).<\/span>\u00a0<\/span><\/p>\n

India is also looking to develop a<\/span> second spaceport spread across 2,300 acres in Tamil<\/span> Nadu\u2019s Kulasekharapatnam.<\/span>\u00a0<\/span><\/p>\n

However, out of these, the cost of launching a satellite into space is a major concern.<\/span>\u00a0<\/span><\/p>\n

What is the cost of launching a satellite and how can it be reduced?<\/span><\/b>\u00a0<\/span><\/h5>\n

At present, it would cost an estimated Rs 14 lakh to put 1 kg in LEO using a PSLV and an estimated Rs 5. 7 lakhs on an Mk3.\u00a0<\/span>\u00a0<\/span><\/p>\n

However, the cost of global space agencies are also along the same line, but there is a need to reduce the cost and that is why reusable rockets holds importance.<\/span>\u00a0<\/span><\/p>\n

According to ISRO scientists, reusable rockets would reduce one-tenth of the present launch cost but India is a long way away from this technology.<\/span>\u00a0<\/span><\/p>\n

Therefore, to cut the launch cost ISRO is planning to build New Generation Launch Vehicle (NGLV) which is reusable.<\/span>\u00a0<\/span><\/p>\n

What can be the further course of action?<\/span><\/b>\u00a0<\/span><\/h5>\n

ISRO is planning in the right direction and it further needs to develop heavier Mk3 and reliable <\/span>Small Satellite Launch Vehicle (SSLV) to fulfil all types of demands.<\/span>\u00a0<\/span><\/p>\n

Further, any unsuccessful mission like Gaganyaaan should not be a setback for ISRO, and it should always prioritise the development of launch vehicles as it is important for future successful missions.<\/span>\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
