PSLV rocket (src:ISRO) After being long in the shackles of British Empire, when India restored freedom it had no idea as to how their dreams for having satellites of their own would be fulfilled. Earlier India took the help of the Russian Space Agency(Roscosmos) for starting its space related missions. India's first satellite Aryabhata was actually launched by Russia's Soyuz. But as the days passed by India felt the need of an indigenously developed launch vehicle. This requirement was completed by the introduction of Polar Satellite Launch Vehicle(PSLV) in 1993. Journey of PSLV- The PSLV was introduced in 1993 and had its first launch in September,1993. The first launch was successful in its initial stages but failed in the later ones. The first and the second stage performed as expected but the third stage encountered a problem of attitude control. This prevented the establishment of the satellite in the orbit and the mission failed. An year later, after the...
NASA, the glittering name in the field of astronomy and space science, suffered two set backs this week as its Kepler and Dawn space missions come to an end. The end of the two space missions has lead to the creation of a vacuum in the field of astronomy. Kepler Mission Kepler Spacecraft src: nasa The Kepler mission was launched on 7 March, 2009 to observe the Cynus and Lyra constellation. The basic aim of the mission was to search for planets similar to Earth where life could be sustained. Kepler worked on the principle that there was a decrease in the intensity of light received by the Kepler when a planet orbiting the star under observation came in front of it. Kepler worked well and good till 2013 when two of the four reaction wheels, responsible for fixing the view of the lens towards the Cynus and Lyra constellation, broke. This left the space probe almost paralyzed and forced the scientists to search for ways to rejuvenate it. The Kepler then was reborn as K2 miss...
The Sun, a source of light and energy for the Milky Way galaxy, is the primal reason for the existence of life on Earth. Besides this the Sun also has some mysteries inside it which have remained hidden as of now. But it looks like the scientists are determined to explore every possible nook and corner of the universe and thus make the human race less dependent on variations occurring in the nature. NASA's Parker Solar Probe is an active and suitable example for this. Parker Solar Probe src: nasa NASA, the American space agency, has recently launched a solar probe named Parker Solar Probe with an aim to disclose the reason behind the abnormal behaviour of the Sun and its surroundings. The solar probe was launched on 12 August,2018 equipped with various high-end electronics to push the limits of the humans in space. The solar probe will be the first ever spacecraft to reach a distance of 3.8 million miles from the Sun. Objective of the Mission - Corona sr...
