• B. 2 and 3 only
• C. 1 and 3 only
• D. All are correct

Answer 1

Answer:

A. 1 and 2 only

• Correct Answer: Option A ) 1 and 2 only

• Chandrayaan-1 was India's first lunar mission launched by the Indian Space Research Organisation (ISRO) on October 22, 2008.

• "It carried international payloads alongside Indian instruments." - True

• Chandrayaan-1 carried 11 scientific instruments in total, including 5 from India and 6 from international partners including NASA, ESA, and Bulgaria. These international payloads helped in comprehensive lunar studies and fostered international collaboration in space research.

• "It mapped the Moon's surface for mineralogical and chemical studies." - True

• One of the primary objectives of Chandrayaan-1 was to create a three-dimensional atlas of the lunar surface and conduct chemical and mineralogical mapping. The mission successfully mapped the entire lunar surface and made significant discoveries, including the detection of water molecules on the lunar surface.

• "It was launched by GSLV Mk II." - False

• Chandrayaan-1 was launched by PSLV-C11 (Polar Satellite Launch Vehicle), not GSLV Mk II. The PSLV is a reliable launch vehicle with a strong track record and was suitable for this lunar mission, while GSLV is typically used for heavier payloads and geostationary orbit missions.
