The X-Ray Spectrometer aboard the
Chang'e-1 moon orbiter started to work on 28 November. The spectrometer was designed and constructed by the Moon Probing Group with the Astroparticle Physics Center of the CAS Institute of High Energy Physics.
The X-ray Spectrometer, composed of an X-ray detector, a solar monitor and an electric-control box, will probe the distribution and contents of useful elements on the moon by analyzing the fluorescent X-ray excited by solar and cosmic rays. Based on the data received through the earth control system of the Beijing Aerospace Control Center, it proves to be working well.
