History
The ASLV made four launches, of which one was successful, two failed to achieve orbit, and a fourth achieved a lower than planned orbit which decayed quickly. The type made its maiden flight on 24 March 1987, and its final flight on 4 May 1994.
Three successive failures plunged the project into a crisis. ISRO scientist had to confront new technological challenges and one of the important design changes was the addition of the 2 strap on boosters attached to either side of the first stage. Strap on separation, bulbous heat shield, "closed loop" guidance system as opposed to the "open loop" guidance system of the SLV-3 and heat shield management and separation had to be adapted by the scientists. However, all the problems and new technological challenges were overcome with ISRO's customary resolve and zeal, and the important ASLV program crossed an important rubicon.

Famous quotes containing the word history:
“We are told that men protect us; that they are generous, even chivalric in their protection. Gentlemen, if your protectors were women, and they took all your property and your children, and paid you half as much for your work, though as well or better done than your own, would you think much of the chivalry which permitted you to sit in street-cars and picked up your pocket- handkerchief?”
—Mary B. Clay, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 3, by Susan B. Anthony and Ida Husted Harper (1902)
“History has neither the venerableness of antiquity, nor the freshness of the modern. It does as if it would go to the beginning of things, which natural history might with reason assume to do; but consider the Universal History, and then tell us,—when did burdock and plantain sprout first?”
—Henry David Thoreau (1817–1862)
“In the history of the human mind, these glowing and ruddy fables precede the noonday thoughts of men, as Aurora the sun’s rays. The matutine intellect of the poet, keeping in advance of the glare of philosophy, always dwells in this auroral atmosphere.”
—Henry David Thoreau (1817–1862)
