Practice questions
Q1Which sequence correctly reflects the Chandrayaan-2 Vikram landing attempt described by ISRO?
ISRO describes Vikram's Chandrayaan-2 landing attempt as taking place on September 7, 2019, with communication lost after descent from 35 km to around 2 km above the lunar surface. Starting with communication loss reverses the sequence, September 2 is the lander-separation date rather than the landing attempt date, and swapping 2 km and 35 km reverses the stated altitude details.
Q2In the 2003 calendar sequence, where does the Government of India's approval of ISRO's proposal for Chandrayaan-1 fall?
The approval falls in November 2003 because the sourced PSLV-C11/Chandrayaan-1 fact says the Government of India approved ISRO's proposal for the first Indian Moon Mission, Chandrayaan-1, in November 2003. Placing it before September 2003, in October 2003, or after December 2003 changes the month given in the cited fact.
Q3Which sequence correctly reflects the sourced conclusion detail of Chandrayaan-1?
The sourced fact states that Chandrayaan-1 made more than 3400 orbits around the Moon before the mission was concluded. Placing the mission conclusion before those orbits reverses the stated order. Saying exactly 3400 or more than 34000 orbits changes the sourced figure.
Q4With reference to Chandrayaan-1's SARA payload, consider the following statements: 1. It imaged the lunar surface using low-energy neutral atoms. 2. Its relevant energy range was 10 eV to 3.2 keV. 3. It used hard X-rays in the 30 keV to 270 keV region. Which of the statements given above are correct?
Statement 1 is correct because SARA imaged the lunar surface using low-energy neutral atoms. Statement 2 is correct because the cited energy range was 10 eV to 3.2 keV. Statement 3 is wrong because 30 keV to 270 keV is the hard X-ray region of the High Energy X-ray Spectrometer, not SARA's low-energy neutral atom range.
Q5Match the Chandrayaan-1 payload detail with the correct sourced description: List I 1. Number of scientific instruments 2. Countries where instruments were built List II a. 11 b. India, USA, UK, Germany, Sweden and Bulgaria c. 8 d. India, Russia, France, Japan, Germany and Sweden Select the correct match.
The correct pairing is 11 scientific instruments and the set of countries India, USA, UK, Germany, Sweden and Bulgaria. The figure 8 is not the sourced instrument count, and the country set including Russia, France and Japan does not match the cited Chandrayaan-1 payload description.
