CHANDRAYAAN-1 was an Indian Space Research Organisation (ISRO) mission launched in collaboration with ESA to study the Moon. It was designed to study the lunar surface at high resolution. It was launched on October 22, 2008. CBK PAN collaborated on two experiments in this project. IR Spectrometer SIR-2 was designed and manufactured for lunar surface observations covering the wavelength range of 0.93-2.4μm with resolution of 6nm. The second instrument CBK PAN was responsible for the Deflector subsystem. Poland created mechanical design and manufactured the instrument.
