चंद्रयान-1 चे शोध आंतराष्ट्रीय दैनिकांत प्रकाशित झालेले आहेत. कोणते अभ्यास चंद्रयान-1 कडून झाले आहेत ?
अ. चंद्राचे रासायनिक मानचित्रण (मॅपिंग)
ब. चंद्राचे खनिजशास्त्रिय मानचित्रण (मॅपिंग)
क. चंद्राचे फोटोजिओलोजिकल (चित्र-भूशास्त्रीय) मानचित्रण
ड. चंद्राचे जीवशास्त्रविषयक मानचित्रण (मॅपिंग)
योग्य पर्याय निवडा :

The correct answer is Option D (Only a, b and c).

Key Points:
• Chandrayaan-1 Science Objectives & Payloads:
• Launched on 22 October 2008 via PSLV-C11 from Sriharikota, carrying 11 scientific payloads (5 Indian, 6 international/NASA/ESA).
• Scientific Investigations Undertaken:
• (a) Chemical Mapping: Carried out by C1XS (Chandrayaan-1 X-ray Spectrometer) and HEX to map magnesium, aluminum, silicon, calcium, and iron distribution.
• (b) Mineralogical Mapping: Carried out by NASA's Moon Mineralogy Mapper (M³) and SIR-2, which confirmed the landmark discovery of water molecules (H₂O/OH) and hydroxyl minerals.
• (c) Photogeological 3D Mapping: Performed by the Terrain Mapping Camera (TMC) and Lunar Laser Ranging Instrument (LLRI) to map lunar surface craters and topography.
• Biological mapping (d) is impossible because the Moon is a sterile, lifeless celestial body without an atmosphere or biological organisms.
• Therefore, the carried out studies were a, b, and c only (Option 4).
• Key Takeaway: Chandrayaan-1 performed chemical, mineralogical, and photogeological mapping, famously discovering water molecules on the Moon.
