Among the given options INTELSAT is an example of communication satellite service provider. As of March 2011, Intelsat operates a fleet of 52 communications satellites, which is one of the world's largest fleet of commercial satellites.

Cosmos is an example of weather satellite. It is a type of satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting, covering the entire Earth asynchronously, or geostationary present over the same spot on the equator.

Ernest Rutherford was a New Zealand-born physicist who lived between 1871-1937. He is considered the father of nuclear physics because of his discoveries on atomic structure.

In the last decade nanotechnology entered the policy arena as a technology that is simultaneously promising and threatening, and with a similar Janus-like face, nanotechnology entered the development agenda.

Earth observation satellites that observe the planet for changes in everything from temperature to ice-sheet coverage is ENVISAT which is an environmental satellite. It is operated by the European Space Agency (ESA), it was the world's largest civilian Earth observation satellite

LLRI stands for Lunar Laser Ranging Instrument. It is an instrument proposed for the first Indian lunar mission Chandrayaan-1 and is aimed to study the topography of the Moon’s surface and its gravitational field by precisely measuring the altitude from a polar orbit around the Moon.

The term atomic age is coined by William L. Laurence.  It is the period of history following the detonation of the first nuclear bomb, Trinity, on July 16, 1945, during World War II. 

Rakesh Sharma was a former Indian Air Force pilot. He was the first Indian person to travel in space. On April 2 in 1984, he made his flight aboard to the Soyuz T-11 and became the first Indian to achieve this milestone.

All three, except Charak, are related to the Mathematics:

•     Boddhayana - The Baudhāyana sūtras are a group of Vedic Sanskrit texts which cover dharma, daily ritual, mathematics, etc. They belong to the Taittiriya branch of the Krishna Yajurveda school and are among the earliest texts of the genre, perhaps compiled in the 8th to 6th centuries BCE.

•     Bhaskaracharya - Bhāskara and his works represent a significant contribution to mathematical and astronomical knowledge in the 12th century.

•     Brahmagupta -  Brahmagupta was an Indian mathematician and a    stronomer. He is the author of two early works on mathematics and astronomy: the Brāhmasphuṭasiddhānta, a theoretical treatise, and the Khaṇḍakhādyaka, a more practical text.
  
  Charak on the other hand was one of the principal contributors to Ayurveda, a system of medicine and lifestyle developed in Ancient India.

The northernmost atomic project is the Rajasthan Atomic Power Station (RAPS).  It is located at Rawatbhata in Rajasthan. It is India’s largest nuclear power plant. Its four reactors are already in operation and four more in the pipeline hopes to make the country self-reliant in its energy requirements. The four operational nuclear power reactors contribute 740 MWe of power out of the national capacity of 2720 MWe being generated from 14 nuclear power reactors.

In the twentieth century drastic progress took place in science and technology as never before.Man received a powerful energy source in the form of atomic energy.Man made progress in space research just as in atomic energy.

Aryabhata, a mathematician and a astronomer, wrote a book in Sanskrit known as the Aryabhatiyam. He stated that day and night were caused by the rotation of earth around its own axis, even though it seems as if the sun is rising and setting everyday. He developed a scientific explanation for eclipses as well. He also found a way of calculating the circumference of a circle, which is nearly as accurate as the formula we use today.

The Sushruta Samhita, written around 6th century BCE, discusses subjects such as General Principles, Pathology, Diagnosis, Anatomy, Sensorial Prognosis, Therapeutics, Pharmaceutics, and Toxicology. It is divided into 186 chapters and contains descriptions of 1120 illnesses, 700 medicinal plants, 300 surgical procedures and 120 surgical instruments.

Prof. Rutherford is called the father of Atomic Energy.

The systematic way of acquiring knowledge through observation and experimentation is called science. It organizes knowledge in the form of testable explanations and predictions. Science includes wide range of topics like biological, physical, chemical, universe, space etc. 

The first nuclear test was conducted in Pokhran.

It is a remote location in the Thar Desert region and served as the test site for India's first underground nuclear weapon detonation.
