ISRO Successful test the High Thrust Vikas Engine

ISRO, the space agency which was created history by successfully launching satellite to mars in his first attempt, is now working on Astronaut space mission.

On July 15, ISRO moves a step ahead by successful test of high thrust version of Vikas Engine. This Engine was successfully qualified through a ground test for a duration of 195 seconds at ISRO Propulsion Complex (IPRC), Mahendragiri, Tamilnadu.

Vikas Engine is the workhorse liquid rocket engine powering the second stage of India’s Polar Satellite Launch Vehicle (PSLV), second stage and the four strap on stages of Geosynchronous Launch Vehicle (GSLV) and the twin engine core liquid stage (L110) of GSLV Mk-III.

All the propulsion parameters during the tests were found satisfactory and closely matched the predictions. This ground test has validated the performance adequacy of the Vikas Engine for its use in the upcoming second developmental flight of GSLV Mk-III. This engine will improve the payload capability of PSLV, GSLV and GSLV Mk-III launch vehicles.

Now with this Engine ISRO is capable to launch more weighted satellites and this will become the base for the space flight for men.

What is Nebula. Images of some nebula by Hubble

A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries." How do stars form in a nebula? Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star. Some of the most amazing nebula pictured by Hubble in Milky Way Galaxy The Eagle Nebula’s Pillars of Creation (M 16, Messier 16) The dust and gas in the pi

STARS GOING OUT OF CONTROL

Stars Gone Haywire. As nuclear fusion engines, most stars live placid lives for hundreds of millions to billions of years. But near the end of their lives they can turn into crazy whirligigs, puffing off shells and jets of hot gas. Thanks to Hubble which give us a chance to view these beautiful stars. The Butterfly Nebula Imagine a lawn sprinkler spinning wildly, tossing out two S-shaped streams. At first it appears chaotic, but if you stare for a while, you can trace its patterns. The same S-shape is present in the Butterfly Nebula, except in this case it is not water in the air, but gas blown out at high speed by a star. The S-shape directly traces the most recent ejections from the central region, since the collisions within the nebula are particularly violent in these specific regions of NGC 6302. "This iron emission is a sensitive tracer of energetic collisions between slower winds and fast winds from the stars. It's commonly observed in supernova remnants and active gala

WHAT IS A BLACK HOLE

In April, NASA created a big announcement that they captured first image of black hole. BUT WHAT IS A BLACK HOLE It is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. The result is a gravitational field so strong that nothing, not even light, can escape. Most famously, black holes were predicted by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core. If the core's mass is more than about three times the mass of the Sun, the equations showed, the force of gravity overwhelms all other forces and produces a black hole. HOW THEY ARE FORMED Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.) If the total mass of the star is large e
