ISRO’s GSAT-17, its objective and features

Jun 28, 2017

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.

What is an Interceptor missile and how it is useful

Mar 2, 2017

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.

Space Missions to the Sun: Brief Analysis

Aug 26, 2016

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 Fleets of Indian Space Research Organisation (ISRO) at a Glance

Feb 1, 2016

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).

Indian Space Research Organisation (ISRO) & India’s Space Facilities

Jan 29, 2016

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.

Earth Surface and Interiors

Aug 16, 2012

Earth, the largest and densest rocky planet, was formed about 4.5 billion years ago. The Earth's interior is divided into four layers which is typical of rocky planets. 

Climate Variability and Change

Aug 16, 2012

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.

Planets

Aug 16, 2012

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.

Water and Energy Cycle

Aug 16, 2012

The Water and Energy Cycle Focus Area studies the distribution, transport and transformation of water and energy within the Earth System.

Weather System

Aug 16, 2012

The weather system includes the dynamics of the atmosphere and its interaction with the oceans and land.

Heliophysics

Aug 13, 2012

The term heliophysics was coined in 1981 to denote the physics of the entire Sun: from centre to corona.

Magnetosphere

Aug 13, 2012

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.

Heliosphere

Aug 13, 2012

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.

Carbon Cycle

Aug 13, 2012

Carbon is a very important element, as it makes up organic matter, which is a part of all life. Carbon follows a certain route on earth, called the carbon cycle.

 

Astrophysics

Aug 13, 2012

Astrophysics is the branch of astronomy that deals with the physics of the universe, including the physical properties of celestial objects, as well as their interactions and behavior.

Black Holes

Aug 11, 2012

Black holes are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole.

Space Environment

Aug 11, 2012

Space environment is a branch of astronautics, aerospace engineering and space physics that seeks to understand and address conditions existing in space that affect the operation of spacecraft.

Inner Solar System

Aug 11, 2012

The Solar System has been broken down into two major parts by astronomers: the inner Solar System and the outer Solar System.

Outer Solar System

Aug 11, 2012

Planetary Science missions to the outer planets help reveal secrets about the solar system by observing those outer distant worlds up close.

The Universe

Dec 11, 2010

The Universe is the sum total of all that exists in space and time.

The Solar System

Dec 11, 2010

The solar system is located 26,100 light years from the centre of the Milky Way and was formed about 4540 million years ago from a globe of gas and dust.

The Milky Way Galaxy

Dec 11, 2010

Our galaxy is considered to be a typical spiral galaxy about 75,000 light years in diameter.

Stars

Dec 11, 2010

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.
