Answer 1

Answer:

• Correct Answer: Option A) 1 and 2 only

• Chandrayaan-1 was announced by PM Vajpayee in his Independence Day speech- True: Prime Minister Atal Bihari Vajpayee announced India's Moon mission (Chandrayaan-1) during his Independence Day address on August 15, 2003.

• It was India's first planetary exploration mission- True: Chandrayaan-1, launched on October 22, 2008, was indeed India's first mission beyond Earth orbit and first planetary exploration mission.

• The spacecraft orbited at 1000 km altitude for high-resolution mapping- False: Chandrayaan-1 initially orbited at approximately 100 km altitude above the lunar surface (not 1000 km). After technical issues, the orbit was raised to 200 km, but it never orbited at 1000 km altitude.
