Chandrayaan‑1

India’s first mission to the Moon.

Mission Snapshot

Launched in 2008, Chandrayaan‑1 was India’s first lunar mission and marked its arrival as a deep‑space agency. The orbiter mapped the Moon in multiple wavelengths and famously helped confirm the presence of water molecules on the lunar surface.

  • 🚀 Launch vehicle: PSLV‑XL
  • 📅 Launch: 22 October 2008
  • 🛰 Mission type: Lunar orbiter
  • 🎯 Key result: Detection of water / hydroxyl signatures.
Why it matters

Chandrayaan‑1 was built on a tight budget, flew international instruments, and still produced world‑class science.

It set the template for ISRO’s “maximum science per rupee” philosophy.

Science Payloads

The orbiter carried a mix of Indian and international instruments: mineral mappers, X‑ray and gamma‑ray spectrometers, a radar altimeter and more. A Moon Impact Probe was also released to study the thin lunar exosphere during descent.
