Attempt This Question
Not attemptedCorrect Answer: (b) 2 and 3 only
Cassini-Huygens was a joint NASA-ESA probe to Saturn, not Venus, so pair 1 is mismatched. Messenger was a NASA spacecraft that orbited and mapped Mercury, and Voyager 1 & 2 were launched to explore the outer Solar System; pairs 2 and 3 are correctly matched. Hence the right option is ‘2 and 3 only’. ([jagranjosh.com](https://www.jagranjosh.com/articles/ias-prelims-2014-general-studies-i-answer-key-1408860511-1?utm_source=openai))
