Question 68: Science and Technology
Which of the following pairs is/are correctly matched?
| Spacecraft | Purpose | |
|---|---|---|
| 1. | Cassini-Huygens | Orbiting the Venus and transmitting data to the Earth |
| 2. | Messenger | Mapping and investigating the Mercury |
| 3. | Voyager 1 and 2 | Exploring the outer solar system |
Select the correct answer using the code given below.
a1 only
b2 and 3 only
c1 and 3 only
d1, 2 and 3
AnswerUPSC’s answer is (b).
Cassini-Huygens was a mission to Saturn and its moons, including Titan, not to Venus, so pair 1 is wrong. MESSENGER was a NASA probe that went into orbit around Mercury in 2011 to map and study the planet. Voyager 1 and 2 were launched in 1977 to explore the outer solar system and later passed into interstellar space. So pairs 2 and 3 are correct.
- 1. Cassini-Huygens went to Saturn and Titan, not Venus.
- 2. MESSENGER mapped and investigated Mercury.
- 3. The Voyagers explored the outer solar system.
Why each option is right or wrong
- (a) Wrong. Cassini-Huygens studied Saturn, not Venus.
- (b) Right. MESSENGER studied Mercury and the Voyagers explored the outer solar system.
- (c) Wrong. Pair 1 is false because Cassini went to Saturn.
- (d) Wrong. Pair 1 is false.
