CHANDRAYAAN-1 SCIENTIFIC PAYLOADS

Chandrayaan-1 is a well –planned mission launched on 22  October 2008, with a significant international participation and with ten scientific  payloads and as impact probe.
Chandrayaan-1 has indigenously developed four core payload/experiments: TMC, HySI, LLRI and HEX and a Moon Impact Probe(MIP) to impact on a predetermined location on the lunar surface.

  • Terrain Mapping stereo Camera (TMC) in the panchromatic band, having 5m spatial resolution and 20 km swath.
  • Hyper Spectral Imaging Camera (HySI) operating in 0.4-0.95 µm band with aspectral resolution of 15 mm and spatial resolution of 80 m with a swath of 20 km
  • Lunar Laser Ranging Instrument (LLRI) with height resolution of less than 5m
  • High Energy X- ray spectrometer (HEX) using Cadminum-Zinc-Telluruide (CdZnTe) detector in the 30-270keV energy region with spatial resolution of 33 km
  • Moon Impact Probe (MIP) as piggyback payload on the main orbiter of the Chandrayaan-1 spacecraft, which will impact on the surface of the Moon.

Apart from the above indigenous payloads/experiments, ISRO solicited proposals through an Announcement of Opportunity (AO) from International and Indian Scientific Community for participating in the mission by providing suitable scientific payloads, complementing the overall Chandrayaan-1 scientific objectives. Out of the proposals received, six experiments were selected for inclusion in Chandrayaan-1 mission; two of the AO payloads, C1Xs and SARA are developed by ESA jointly with ISRO.

  • Chandrayaan-1 X-ray Spectrometer (C1XS) through ESA – collaboration between RutherfordAppleton Laboratory, UK and ISRO Satellite Centre, ISRO. Part of this payload is redesigned by ISRO to suit Chandrayaan-1 scientific objective.
  • Near Infra Red spectrometer (SIR-2) from Max Plank Institute, Lindau, Germany through ESA.
  • Sub keV Atom Reflecting Analyser (SARA) through ESA, collaboration between Swedish Institute of Space Physics, Sweden and Space Physics Laboratory, Vikram Sarabhai Space Center, ISRO. The Data Processing Unit of this payload/experiment is designed and developed by ISRO, while Swedish Institute of Space Physics has developed the payload sensor.
  • Radiation Dose Monitor Experiment (RADOM) from Bulgarian Academy of Sciences.
  • Miniature Synthetic Aperture Radar (Mini-SAR) from Applied Physics Laboratory, Johns Hopkins University and Naval Air Warfare Centre, USA through NASA.
  • Moon Mineralogy Mapper (M3) from Brown University and Jet Propulsion Laboratory, USA through NASA.
