Science & Technology Mixed Quiz: Set 2

It has three solid stages and a small liquid velocity trimming module, carries up to about 500 kg to a 500 km low earth orbit, and is designed to be assembled and launched by a small team within days so that a customer with one satellite need not wait for…

The Specific Absorption Rate measures how much radio energy from a handset the body takes in, in watts per kilogram of tissue.

GAGAN stands for GPS Aided GEO Augmented Navigation and was developed by ISRO together with the Airports Authority so that civil aircraft in Indian airspace get position information accurate and reliable enough for approach and landing.

The Integrated Guided Missile Development Programme was approved in 1983 and run by the DRDO under Dr A.P.J. Abdul Kalam, which is why he is called the Missile Man of India.

Chandrayaan 1 was launched on 22 October 2008 from the Satish Dhawan Space Centre at Sriharikota and reached lunar orbit within a fortnight.

It was launched on 19 April 1975 by a Soviet launch vehicle, since India had no vehicle of its own at the time, and it carried experiments in X-ray astronomy, solar physics and the ionosphere.

Gaganyaan will fly on the LVM3, the heaviest Indian launch vehicle, modified and certified for carrying human beings and then written as HLVM3.

Chandrayaan-3 weighed close to 3,900 kg at lift-off, far beyond the reach of any lighter Indian rocket, so it flew on LVM3, the vehicle earlier named GSLV Mk III.

Pinaka is the multi-barrel rocket launcher built for the Indian Army by DRDO's Armament Research and Development Establishment, Pune, and named after the bow of Lord Shiva.

Prithvi II is test-fired from the Integrated Test Range at Chandipur on the Odisha coast, the DRDO range used for missile and rocket trials.

Bias in an artificial intelligence system is traced to three sources, the data it learns from, the algorithm that learns, and the people who build and use it; ability is not one of them, because the skill of a model is a measure of how well it performs, not a…

The name was given in 2016 to the Indian Regional Navigation Satellite System, IRNSS, when the seventh satellite of the constellation was placed in orbit, and the word navik also carries the sense of a sailor or navigator, which is why it was chosen.

The full name of the satellite, Ariane Passenger Payload Experiment, contains the answer, since it flew as a passenger on an Ariane launch in 1981 to test the building of a geostationary communication satellite in India.

On 18 July 1980 the four-stage, all-solid SLV-3 placed the small Rohini RS-1 satellite in a low earth orbit from Sriharikota, and India became the sixth nation able to launch its own satellite.

The Polar Satellite Launch Vehicle in its extended configuration carried Chandrayaan 1 on 22 October 2008. The same family of rockets, in the C25 flight, later carried the Mars Orbiter Mission in 2013, which shows how much the Indian space programme achieved with a medium lift vehicle.

The system was designed as a constellation of seven satellites, three of them in geostationary orbit and four in geosynchronous orbits inclined to the equatorial plane, a small number being enough because the service area is regional and not global.

Rakesh Sharma, then a Squadron Leader in the Indian Air Force, became the first Indian in space on 3 April 1984.

The American computer scientist John McCarthy is called the father of artificial intelligence because he coined the term itself in his proposal for the Dartmouth summer research project of 1956, the meeting at which the field was born.

This imaging spectrometer, supplied by the United States space agency and flown on the Indian orbiter, measured how sunlight reflected from the lunar surface and found the absorption signature of water molecules and hydroxyl, especially towards the poles.

Rakesh Sharma flew on Soyuz T-11, launched from Baikonur on 2 April 1984, and docked with the Soviet space station Salyut 7.
