Chandrayaan-1, India's first spacecraft mission to the moon, was successfully launched by:

Correct option is B

The correct answer is (b) PSLV-C11.

Chandrayaan-1, India's first mission to the Moon, was successfully launched on October 22, 2008, using the PSLV-C11 (Polar Satellite Launch Vehicle) rocket. The mission was a significant milestone in India's space exploration efforts, as it made important discoveries, including the detection of water molecules on the Moon's surface. The spacecraft was launched from the Satish Dhawan Space Centre in Sriharikota, and it played a vital role in strengthening India's position in space science.

Information Booster

• PSLV-C11
  • A polar satellite launch vehicle, known for its versatility and reliability.
  • Successfully launched Chandrayaan-1 in 2008.
  • The PSLV-C11 is designed for launching satellites into polar orbits and is one of the most used rockets by the Indian ISRO (Indian Space Research Organisation).

Additional Knowledge

• GSLV MkIII

  • The Geosynchronous Satellite Launch Vehicle Mark III is a heavier and more powerful rocket, used for launching more massive payloads into geostationary orbits.
  • It was not used for Chandrayaan-1, but it was used for Chandrayaan-2 in 2019.

• RLV-TD

  • The Reusable Launch Vehicle Technology Demonstrator is an experimental program by ISRO aimed at developing a reusable spaceplane.
  • It was not used for Chandrayaan-1; it is a different project for future space missions.

• GSLV

  • The Geosynchronous Satellite Launch Vehicle is a rocket used for launching satellites into geosynchronous orbits.
  • It was not used for the Chandrayaan-1 mission, which required a smaller launch vehicle like the PSLV.
