Question
Fill in the blank and explain the statement with reasoning:
The initial velocity (during launching) of the Managalyaan, must be greater than ______ of the earth.
Solution
The initial velocity (during launching) of the Managalyaan, must be greater than escape velocity of the earth.
Explanation:
Since 24 September 2014, the Mars Orbiter Mission, also known as Mangalyaan, has been orbiting Mars.
It was launched by the Indian Space Research Organization on 5 November 2013.
The initial speed of Mangalyaan must be higher than the escape speed of the earth, which is 11.2 km/s.
The answer to the question is therefore 11.2 km/s.
It travelled over 200 million kilometers and entered the Red Planet's orbit successfully.
The ISRO launched it and was an extremely successful project.
