India to launch radar satellite in 2020 Gandhinagar: India will launch in 2020 an advanced satellite equipped with synthetic aperture radar, the first of its kind in the world, that the country is developing in collaboration with NASA, said Indian Space Research Organization (ISRO) former chairman K.Radhakrishnan. Defence Research and Development Organisation (DRDO) director Dr G.Satheesh Reddy said the "smart soldier" concept for the countryâ€™s armed forces was at a critical stage in its development. The two were showcasing India's scientific achievement at the Youth Pravasi Bharatiya Divas. The radar satellite was a key link in India's space research collaboration with NASA. The satellite will incorporate advanced instruments to study in detail climate change, the melting of ice and glaciers, earthquakes, tsunamis, landslides and volcanoes, among others. The studies are important as these phenomena are still not fully understood or can by accurately predicted. The satellite will use two different radar frequencies. The launch vehicle, the launch, the satellite bus, etc. will be India's responsibility. NASA will develop the radar, the communications sub-system, and the GPS receiver, among others. Radhakrishnan said India now occupies the top spot in several areas of space research. The country's 25 satellites now orbit the earth. He said with the Mark III engine, which was successfully tested recently -- getting ready, the country will become self-sufficient in launching heavy satellites. He was greeted with thunderous applause by the audience when he said he can foresee a time when delegates from Mars will attend the Pravasi Bharatiya Divas meet. Satheesh Reddy's smart soldier concept can revolutionise warfare. It includes a battlefield attire incorporating technologies that can spot and neutralise the enemy's moves and launch a counter-attack. Reddy said the "robo soldier" concept, which aims to field bots in the battlefield, was also in the works. From one that possessed zero capability to build missiles, India has now transformed itself into a country that has top-notch missiles in all categories, he said. Earlier, with each achievement, scientists used to take pride in the fact that the country was one of the five, or one of the four, possessing that technology. Then DRDO chief Dr APJ Abdul Kalam used to ask at those times, "Funny fellows, don't we have to be first in the world?" Today, the country is top on supersonic missiles and anti-missile technologies, and have fulfilled Kalamâ€™s dreams, Reddy said. Union science and technology minister Dr Harshvardhan introduced Dr K Radhakrishnan to the delegates of the Youth Pravasi Bharatiya Divas meet as "the great man." In the special session to describe India's scientific achievements, the minister took special care to praise ISRO. He also wondered if it was correct to call someone who had retired just a few days back as ISRO's former chief. He invited Radhakrishnan for his lecture with the introduction that the scientist will not be allowed to "retire and restâ€.
