Consider the following statements : The Mangalyaan launched by ISRO 1. is also called the Mars Orbiter Mission 2. made India the second country to have a spacecraft orbit the Mars after USA 3. made India the only country to be successful in making its spacecraft orbit the Mars in its very first attempt Which of the statements given above is/are correct?
- A.1 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
Correct answer
Explanation
The correct answer is C, 1 and 3 only. Mangalyaan is the popular name of ISRO's Mars Orbiter Mission, and India reached Mars orbit on its first attempt, but it was not the second country to do so. The spacecraft was launched on 5 November 2013 by PSLV-C25 from Sriharikota and entered orbit around Mars on 24 September 2014. With that, ISRO became the fourth space agency to reach Mars orbit, after the Soviet space programme, NASA of the United States and the European Space Agency. India was the first country to succeed on its maiden attempt and the first Asian country to reach Mars orbit. The mission was also noted for its low cost, about 450 crore rupees. Statement 1 is correct and statement 3 is correct. Statement 2 is wrong because the Soviet Union and the European Space Agency had reached Mars orbit before India. So option A is wrong because it leaves out statement 3, and options B and D are wrong because they include statement 2. Exam tip: Mangalyaan = MOM, launched 5 Nov 2013, Mars orbit 24 Sep 2014, fourth agency, first on maiden attempt.
