Chandrayaan-1 Payloads
The scientific payload had a mass of 90 kg and contained five Indian instruments and six instruments from other countries — a landmark of international collaboration.
Indian instruments
- Terrain Mapping Camera (TMC) — stereo CMOS camera, 5 m resolution, for a complete topographic map of the Moon.
- Hyper Spectral Imager (HySI) — mineralogical mapping in the 400–900 nm band.
- Lunar Laser Ranging Instrument (LLRI) — laser altimeter measuring surface topography.
- High Energy X-ray Spectrometer (HEX) — 30–200 keV measurements of radioactive elements.
- Moon Impact Probe (MIP) — impactor that struck the south pole and detected water vapour.
International instruments
- C1XS X-ray Spectrometer (UK/ESA/ISRO) — mapped Mg, Al, Si, Ca, Ti and Fe abundance.
- SARA — Sub-keV Atom Reflecting Analyser (ESA) — mapped composition using low-energy neutral atoms.
- M3 — Moon Mineralogy Mapper (NASA) — imaging spectrometer that found water/hydroxyl signatures.
- SIR-2 Near-Infrared Spectrometer (ESA) — mineral composition via infrared grating spectrometer.
- Mini-SAR (NASA) — synthetic aperture radar hunting for polar water ice.
- RADOM-7 Radiation Dose Monitor (Bulgaria) — mapped the radiation environment around the Moon.
