Space agency ISRO sent up a rocket carrying India’s 100th satellite along with 30 others, four months after a constant launch failure. The Polar Satellite Launch Vehicle or PSLV lifted off at 9.29 am from Sriharikota (Andhra Pradesh) and a major module that had failed in August didn’t let it down this time, causing relief to the scientists at having crossed a vital hiccup.
1) The 30 other satellites include two other satellites from India and 28 satellites from Canada, Finland, France, Korea, United Kingdom and the United States
2) This will be done through the “multiple burn technology” under which the rocket’s engine is switched off and then switched on to get control of its height.
3) The whole process will consume 2 hours 21 minutes-the longest so far.
4) The heat shield of a satellite is meant to protect it from the friction heat against atmosphere during take-off.
5) The launch became necessary after three atomic clocks of one satellite started malfunctioning. Atomic clocks give out the navigational data and they play a vital role in a Global positioning system.
6) NAViC (system consisting of 7 satellites) powers India’s powerful homegrown Global Positioning System.
7) ISRO’s workhorse PSLV rocket weighs nearly 320 tonnes and has a height of 44.4 meters which is equivalent to a 15-story skyscraper.
