Question 14
EasyOriginal questionOn 22 October 2008, a PSLV rocket lifted off from Sriharikota carrying Chandrayaan-1, India's first to the Moon. The spacecraft weighed about 1,380 kg at launch and was built to circle the Moon at a height of 100 km, mapping its surface, its minerals and the chemicals in its rocks.
It was also an effort. Of the eleven scientific instruments on board, some were built in India and others came from the United States, the United Kingdom, Germany, Sweden and Bulgaria. Scientists from many countries were therefore waiting for the data it would send back.
The mission was planned to last two years. , it achieved its major objectives well before that, and in May 2009 its orbit was raised to 200 km. Chandrayaan-1 went round the Moon more than 3,400 times. On 29 August 2009, contact with the spacecraft was lost, and the mission came to an end after less than a year in orbit.
Even so, it had done what it set out to do, and it opened the way for the Chandrayaan missions that followed.
What did Chandrayaan-1 do in May 2009?
Show the answer and explanation
Correct answer: A
Explanation
The third paragraph says that "in May 2009 its orbit was raised to 200 km".
Worth noting
Chandrayaan-1 circled the Moon; the passage never says it landed. Contact was lost in August 2009, not May.
