2. Historical Background of Chandrayaan Missions

India’s Lunar Journey: Chandrayaan Missions

Chandrayaan-1 (2008): India’s First Leap

• India made history by launching its first mission to the Moon, marking its entry into global lunar exploration.
• The biggest breakthrough? The discovery of water molecules on the Moon’s surface, later confirmed by NASA.
• This mission placed India among an elite group of five nations that had reached the Moon.

Chandrayaan-2 (2019): Ambition Meets Challenge

• ISRO aimed higher with a more advanced mission, including an orbiter, lander (Vikram), and rover (Pragyan).
• The goal was a soft landing, but just moments before touchdown, ISRO lost contact with Vikram, leading to a crash.
• Despite the setback, the orbiter remains operational, sending valuable data on the Moon’s surface and atmosphere.

Chandrayaan-3 (2023): Triumph at the South Pole

• A determined follow-up to correct Chandrayaan-2’s shortcomings, it successfully landed on the Moon’s south pole.
• Equipped with scientific instruments:
  • ChaSTE measured the Moon’s surface temperature.
  • ILSA detected seismic activity.
  • APXS & LIBS analyzed the elemental composition of lunar soil.

Each Chandrayaan mission has pushed India further into the global space frontier, paving the way for Chandrayaan-4’s ambitious lunar sample return in 2027.
