Two more Chandrayaan instruments to be activated in the middle of December

Two of the 10 remaining scientific instruments onboard India’s first unmanned lunar mission Chandrayaan-1 will be activated in mid-December for conducting experiments.
The sub-kiloelectronvolt (keV) atom reflecting analyser (SARA) and the high-energy x-ray spectrometer (HEX) are scheduled to be activated in mid-December as they need favourable condition from the sun angle. The remaining eight payloads have been energised and are functioning well.
Of the 11 payloads, the moon impact probe (MIP) was successfully lowered onto the lunar surface Nov 14 with excellent results. The other eight instruments are – mini synthetic aperture radar (MiniSAR), moon mineralogy mapper (M3), radiation dose monitor (RADOM), terrain mapping camera (TMC), hyper-spectral imager (HySI), lunar laser ranging instrument (LLRI), imaging x-ray spectrometer (C1XS) and smart near infrared spectrometer (SIR-2).
The MIP camera took about 3,000 images during its 25-minute descent. Some of the images include the ridge of the Shackleton crater and a vivid picture of the field where the probe crash-landed, thus confirming the execution was precise and at the designated place. They are a valuable catch.
The data, received from the mother spacecraft at the deep space network (DSN) at Byalalu, about 40 km from Bangalore, is being caliberated and studied by ISRO scientists.The data is so voluminous that it will take three months to analyse by our experts. The third instrument – the c-band altimeter gave the trajectory of the descent and confirmed whatever we have done was on target. The MIP experiment is unique as the Chinese and Japanese lunar missions did not have such a one.
