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.

25 June 1975 BLACK DAY FOR INDIA (EMERGENCY)

25 June which is considered as black day for india. It was 25 June 1975 when Prime Minister Shri Indri Gandhi declared Emergency through radio in India. In India, "the Emergency" refers to a 21-month period from 1975 to 1977, Officially issued by President Fakhruddin Ali Ahmed under Article 352 of the Constitution, the Emergency was in effect from 25 June 1975 until its withdrawal on 21 March 1977. The order bestowed upon the Prime Minister the authority to rule by decree, allowing elections to be suspended and civil liberties to be curbed. For much of the Emergency, most of Gandhi's political opponents were imprisoned and the press was censored. Several other human rights violations were reported from the time, including a forced mass-sterilization campaign spearheaded by Sanjay Gandhi, the Prime Minister's son. RESION BEHIND EMERGENCY On 12 June 1975, Justice Jagmohanlal Sinha of the Allahabad High Court found the prime minister guilty on the charge of...

Spiral Galaxy Images taken by Hubble Telescope

This is the Andromeda galaxy — otherwise known as M31. This is the neighbouring galaxy of Milky way galaxy (our own galaxy). This is nearly 2 million light years away from earth. This is a NGC 7640 i. e. barred spiral type galaxy. These are recognisable by their spiral arms, which fan out not from a circular core, but from an elongated bar cutting through the galaxy’s centre. This is the part of Andromeda constellation. This is the image of the beautiful barred spiral galaxy NGC 1300. NGC 1300 is considered to be prototypical of barred spiral galaxies. Barred spirals differ from normal spiral galaxies in that the arms of the galaxy do not spiral all the way into the center, but are connected to the two ends of a straight bar of stars containing the nucleus at its center. This 60 million light years away from the earth and belong to the Eridanus Constellation. This is spiral galaxy Messier 77 — a galaxy in the constellation of Cetus, some 45 million light-y...
