The probe will be in relay with a satellite in halo orbit of the Earth-Moon Lagrange Point L2 launched half a year in advance. Unlike Chang’e-3, the probe will be equipped a low-frequency radio spectrometer. Since the far side of the moon is shielded from electromagnetic interference from the Earth, it’s an ideal place to research the space environment and solar bursts, and the probe can ‘listen’ to the deeper reaches of the cosmos.
