GSAT-17 is a communication satellite by Ariane-5 launch vehicle from the Guiana Space Centre in Kourou, French Guiana. It will provide replacement capacity supporting the existing television, telecommunication, Digital Satellite news Gathering (DSNG) and VSAT services in the country. This article deals with the ISRO’s GSAT-17 satellite, its features and objective.
The interceptor missile is an anti-ballistic missile (ABM) which is a surface-to-air missile designed to counter ballistic missiles like intermediate range and intercontinental ballistic missiles launched from any country. It is used to deliver nuclear, chemical, biological or conventional warheads in a ballistic flight trajectory. How interceptor missile works and how it is useful is discussed in this article.
The Sun is the star at the centre of the solar system. It is mainly composed of hydrogen and helium. There are various solar missions launched by observatories to study high resolution and close-up view of Sun and its inner heliosphere (the innermost region of our Solar System) to predict and to better understand the intractable or restive behaviour of the star on which our lives depend.
Launch vehicles are used to transport and put satellites or spacecrafts into spaces. The first experimental Satellite Launch Vehicle (SLV-3) was developed in 1980. India has made tremendous strides in launch vehicle technology to achieve self-reliance by the operationalisation of Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV).
The Indian Space programme began in 1962. In 1969, The Indian Space Research Organisation (ISRO) was set up with headquartered in Bangaluru (Bangalore) for the purpose of rapid development in space technology. India launched its first satellite “Aryabhatta” under the leadership of India's first Prime Minister Jawaharlal Nehru, and his close aide and scientist Vikram Sarabhai.
The Climate Variability and Change program seeks to deliver new knowledge and applications for decision-making in climate-sensitive industries and to understand and project climate variability and change and its impacts to improve adaptive responses and to inform policy and decision making.
All eight planets can be seen with a small telescope; or binoculars. And large observatories continue to provide much useful information. But the possibility of getting up close with interplanetary spacecraft has revolutionized planetary science.
The study of the region of space near the Earth helps to determine changes in the Earth's magnetosphere, ionosphere, and upper atmosphere in order to enable specification, prediction, and mitigation of their effects.
The heliosphere is a bubble of charged particles in the space surrounding the Solar System, "blown" into the interstellar medium (the hydrogen and helium gas that permeates the galaxy) by the solar wind.
Stars are accretions of gas that radiate energy through nuclear fusion reactions. Stars form from the gravitational contraction of a cloud of gas and dust with a central core forming rapidly and the remainder of the surrounding cloud falling onto the core to form the star.
