Payload Development

Infrared mapping by the Moon Mineralogy Mapper on Chandrayaan-1 resulted in the detection of hydroxyl (OH) and water on the uppermost few millimeters of the lunar surface. This was a landmark discovery from planetary science research in our division.
Several instruments are developed/under development in-house by Planetary Science Division members for ISRO’s planetary missions like Chandrayaan-1, Chandrayaan-2, Aditya-L1 and future Mars/Venus missions. These include the following:

• High Energy X-ray Spectrometer
• Alpha Particle X-ray Spectrometer
• Solar X-Ray Monitor
• Chandra’s Surface Thermophysical Experiment(in collaboration with SPL/VSSC)
• Aditya Solar Wind Particle Experiment
• Gamma Ray Spectrometer
• Inter Digitated Transducer Dust Detector
• Impact Ionization Dust Detector
• Lightning Detector
• Radio Occultation Experiment
• Retarding Potential Analyzer
• Langmuir Probe
• Neutral and Ion Mass Spectrometer
• Energetic Ion Spectrometer
