To the Moon and Beyond: The Timeline of India's Chandrayaan Fleet

India's lunar exploration program, Chandrayaan, has evolved rapidly from an orbit-only science experiment into a fully realized polar landing program.

Here is a breakdown of the three major milestones in the Chandrayaan series:

1. Chandrayaan-1 (2008): Detecting Water Ice

Launched in October 2008, Chandrayaan-1 carried the Moon Impact Probe (MIP), which deliberately struck the lunar surface near Shackleton Crater.

• Discovery: The Moon Mineralogy Mapper ($M^3$), an instrument provided by NASA onboard, conclusively detected the presence of water-ice crystals and hydroxyl molecules in permanently shadowed polar areas, rewriting scientific textbooks.

2. Chandrayaan-2 (2019): A Valiant Attempt

Designed as a massive three-in-one mission containing an Orbiter, a Lander (Vikram), and a Rover (Pragyan).

• The Snag: During the final "15 minutes of terror" of autonomous descent, a minor software glitch caused Vikram to crash-land.
• The Silver Lining: The Orbiter remained completely healthy and continues to relay extremely high-resolution 30cm images of the lunar terrain.

3. Chandrayaan-3 (2023): Perfect Landing

Focusing strictly on landing, this mission carried no complex orbiter (relying instead on Chandrayaan-2's orbiter for relay). It successfully achieved a soft landing on August 23, 2023, establishing the "Shiv Shakti Point" on the Moon.
