Geosynchronous satellite is placed in the geosynchronous orbit with an orbital period matching the Earth's rotation period. These satellites take 24 hours to complete one rotation around the earth. However, the orbital plane for a typical geosynchronous satellite is generally not the equatorial plane.

The communication platforms based on the communication with the help of these satellites are know. Cryogenics is the study of the production and behaviour of materials at extremely low temperatures below degree Centigrade to lift and place the heavier objects in space. Description: Cryogenic stage is technically a much more complexed system with respect to solid or liquid prop.

In astronomical terms, perturbation is the complex motion observed in a massive body that is subjected to forces other than the gravitational pull by another single, massive body. Other forces can include a third body force, resistance caused by another body, as from an atmosphere, and the off-centre attraction of an oblate body. Description: Perturbations first began to be studied in order to.

These radiant sources were formed approximately twelve billion years ago. Quasar formations take place by collision of galaxies, i. Quasars were foremost identified as red shift sources. It was launched in and is one of the great observatories of NASA. Description: Hubble was created with a need to capture high-resolution images of universe.

It is capable of taking high-resolution images with negligible background light. History: Though the HST launched in , the idea of maki. Heliopause is the outer edge of the heliosphere which acts as the surface of the bubble that surrounds our solar system.

The Heliopause is that part of the solar system which is exposed to particles and ions of deep space. Description: Heliopause is the boundary of the heliosphere which is the spherical region around the Sun.

It is filled with solar magnetic fields and solar wind that consists. Solar panels are those devices which are used to absorb the sun's rays and convert them into electricity or heat. Description: A solar panel is actually a collection of solar or photovoltaic cells, which can be used to generate electricity through photovoltaic effect.

These cells are arranged in a grid-like pattern on the surface of solar panels. Thus, it may also be described as a set of. An aurora is a natural phenomenon which is characterised by a display of a natural-coloured green, red, yellow or white light in the sky.

It is predomi. ISRO was formed in with a vision to develop and harness space technology in national development, while pursuing planetary exploration and space science research. A Lagrangian point is a position or location in space where the combined gravitational forces of two large bodies is equal to the centrifugal force that is felt by a third body which is relatively smaller. The two large bodies here may be the Earth and Sun or the Earth and Moon.

Description: A lagrangian point is also known as a Lagrange point, Liberation point, or L-point. These points are loc. All rights reserved. For reprint rights: Times Syndication Service. Choose your reason below and click on the Report button.

Everything that is needed for life support food, air and water is carried along with astronauts. But this is not a viable solution for the long-term manned missions or a space establishment. Hence, the idea of CELSS came into picture with an aim of creating an environment which is regenerative and can support human life via agricultural means.

CELSS has three major components: 1. Air Regeneration: With the help of foliage plants that emit oxygen during photosynthesis assisted by human respiratory waste, CO2. Water is derived from the excess moisture released by plants as well as from vapours condensate in the air. Waste water revitalization: Specifically designed systems to process waste water to use in toilets and watering plants as well as with the help of aquatic plants in treating water for drinking purpose.

It is actually the transition between corona and the photosphere. It is about 2, to 3, kilometres deep, which is located immediately above the photosphere and just below the corona.

It is normally not visible because its density is very low and due to the excessive brightness of the photosphere. The chromosphere, thus, can be only seen during a complete solar eclipse. During the total eclipse, the moon hides the photosphere and makes way for the reddish chromosphere to be seen. The temperature rises as chromosphere moves farther away from the Sun unlike other objects of the solar system. The temperature of photosphere, for instance, decreases as it moves away from the Sun.

One of the important features of the chromosphere is the presence of spicules on its edges. The spicules are long and thin finger-like gaseous spikes which rise through the chromosphere. The spectrum of chromosphere has emission lines, with H-alpha lines being the strongest of emission lines.

It is the H-alpha emission which actually gives the chromosphere its reddish colour. The red rim can be seen when this H-alpha burns at a high temperature during a total solar eclipse.

The mission comprised an orbiter and an impactor. Launched successfully by the Indian Space Research Organisation ISRO on October 22, , the spacecraft was designed to study the Moon orbiting around it at a height of km from the lunar surface.

Description: The mission provided a major boost to the Indian space program as India effectively researched and indigenously developed the technology to explore the Moon. Chandrayaan-1 was launched aboard PSLV-C11 launch vehicle which successfully inserted the spacecraft into the lunar orbit on November 8, On November 14, , MIP Moon Impact Probe was separated which struck the lunar South Pole in a controlled manner and India emerged as the fourth country in the world to hoist its flag on lunar surface.

After almost a year due to several technical issues and contact failure on August 29, , the ISRO officially declared the mission over. Related Definitions. Popular Categories Markets Live!

CHANDRAYAAN - 1

Overview Segments Results Gallery. The idea of undertaking an Indian scientific mission to Moon was initially mooted in a meeting of the Indian Academy of Sciences in that was followed up by discussions in the Astronautical Society of India in Leading Indian scientists and technologists participated in the deliberations of the Task Force that provided an assessment on the feasibility of an Indian Mission to the Moon as well as dwelt on the focus of such a mission and its possible configuration. After detailed discussions, it was unanimously recommended that India should undertake the Mission to Moon, particularly in view of the renewed international interest in moon with several exciting missions planned for the new millennium. In addition, such a mission could provide the needed thrust to basic science and engineering research in the country including new challenges to ISRO to go beyond the Geostationary Orbit. Further, such a project could also help bringing in young talents to the arena of fundamental research.

Chandrayaan 1- ISRO’s first moon mission has left a glorious legacy! Here’s all you need to know

Chandrayaan-1 was India's first mission to the moon. It operated for almost a year between October and August The lunar orbiter is best known for helping to discover evidence of water molecules on the moon. The Chandrayaan-1 spacecraft was based on an Indian meteorological satellite called Kalpansat. It was about the size of a refrigerator, with a dry weight weight without fuel of about kilograms 1, lbs. Chandrayaan-1 launched on Oct.
