India's heaviest satellite GSAT-19 launched

India's heaviest satellite GSAT-19 launched

The communication satellite GSAT-19 weighs 3136 kilogram during lift off and its intended mission life is ten years. Space X chief launch buggy, Falcon 9 has a payload capacity in excess of 8,000 kg.

The first suborbital test flight of GSLV Mk III was successfully conducted on December 18, 2014. ISRO is still using GSLV Mark II. Its predecessor GSLV Mark II has already become flight-proven with four consecutive successes since January 2014. Beyond ramping up the launch rate itself, his colleagues stated that ISRO will also have to get working on launching six-tonne satellites in the future.

Work on Mark III began early in the millennium but there were many obstacles.

He added that India has "mastered" the cryogenic engine technology with the successful flight demonstration of the CE-20 engine, which generates 44,000 pounds of thrust in vacuum, twice the power of the USA -built Aerojet Rocketdyne RL10 cryogenic engine used on Atlas 5 and Delta 4 rockets. As reported by TOI, the total project cost is estimated to be at ₹2,900 crore.

In order to build a heavy launch rocket, ISRO needed to ideal multi-stage cryogenic engines (engines that use gases liquefied and stored at very low temperatures). If turning the two gases into liquids is tough, making the right kind of tanks that store them and the engines that receive them with the right alloys that can withstand such low temperatures is even tougher.

Hackers could have framed Russia
Comey may criticize the President's actions during his testimony, he will leave the questions of their ultimate legality to Mr. Putin said he was surprised with that hullaballoo around some alleged contacts between Russia's ambassador and Trump team.

The height of the rocket's upper stage is 25 metres and it carries 28 tons of cryo fuel. CE-20 will power the combustor cycle. It also has an acoustic suppression system to keep the noise levels low.

The development of the rocket started back in 1994.

Other than communication satellites, the payload on board the rocket will consist of machinery to be used in monitoring and studying the nature of charged particles and the influence of space radiation on satellites and their electronic components.

India successfully launched its heaviest-ever rocket on Monday which it hopes will eventually be able to carry astronauts into space, a feat that only Russian Federation, the United States and China have achieved, its space agency said. Other improvements, now in the pipeline, will enable Mark III to carry heavier payloads. The United States, Russia, China, Japan and European Space Agency have launched satellites weighing over three tonne.

"The countdown for India's heaviest rocket is progressing smoothly". In 1998, India tested nuclear devices for the second time, leading to more sanctions and therefore the denial of cryogenic engine technology.
