What is the name of the engine that has been developed by the ISRO, which has become the India's first indigenously designed and developed high-thrust rocket engine generating a nominal thrust of 19 tonnes has been successfully endurance hot-tested for 800 seconds?: cryogenic rocket engine
Explanation: Cryogenic engine of C25 Stage operates on Gas Generator Cycle using extremely low temperature propellants Liquid Hydrogen (LH2) at 20 Kelvin (-253 deg C) and Liquid Oxygen (LOX) at 80K (-193 deg C). Thus the engine will be used for powering the Cryogenic stage (C25), the upper stage of the next generation GSLV Mk-III launch vehicle of ISRO, capable of launching four-tonne class satellites. The engine design was totally an in-house effort with experts from different fields like fluid dynamics, combustion, thermal, structural, metallurgy, fabrication, rotor dynamics and control components working together.
What is the name of the Indigenous Visibility Measuring System which has been installed at New Delhi’s Indira Gandhi International Airport thus it become the first Airport in the country to have 10 indigenous systems operating in all its three runways?: Drishti
Explanation: “Drishti” is the name of the indigenously designed Visibility Measuring System which is localy designed and developed by CSIR-National Aerospace Laboratories (CSIR-NAL), Bengaluru and it is made to enable it as easy installation and maintenance. The technology will be primarily used for reporting the runway visual range, which is a critical parameter for safe landing and take-off of aircraft in poor visibility conditions (<25 to >2000 meters). The “Drishti” system is very cost-effective and is a mandatory system required at all airports as per International Civil Aviation Organisation (ICAO) and World Meteorological Organisation (WMO).
Which British physicist on 20 July 2015 launches $100 million search for aliens?: Stephen Hawking
Explanation: British physicist Stephen Hawking with Russian-born billionaire Yuri Milner on 20 July 2015 had announced their ambitious bid to search for extraterrestrial life. The project will include "listening" program — the effort to analyze vast amounts of radio signals in search of signs of life — and a "messaging" program that will include $1 million in prizes for digital messages that best represent the planet Earth. Search of Allein will be supported by the world’s most finest and largest telscopes like 100-meter Robert C Byrd Green Bank Telescope in West Virginia in the United States and the 64-meter Parkes Telescope in New South Wales, Australia and the Lick Observatory in California will conduct a deeper-than-ever search for optical laser transmissions.
On 14 July 2015 which NASA spacecraft has made a history when it flyby of the dwarf planet Pluto some 4.8 billion kilometers from Earth launched from earth in year 2006?: ‘New Horizons’
Explanation: New Horizons, the NASA space probe to study the dwarf planet Pluto, was launched from Cape Canaveral on 19 January 2006.

With this history, scientists also have learned that Pluto (which is once considered the ninth and outermost planet of the solar system) is bigger than Eris with a diameter of about 1,473 miles (2,370 km), some 50 miles (80 km) wider. Eris, one of hundreds of thousands of mini-planets and comet-like objects circling beyond Neptune in a region called the Kuiper Belt. The exact time when New Horizons was closest to Pluto was about 5:19 pm in India. However, the news of its successful flyby was received through a signal in the early morning of 15 July 2015 (IST).
