Chang’e-4 was a backup probe for the Chang’e-3 mission that landed a spacecraft on the moon two years ago.
"China will be the first to complete the task if it is successful," the agency cited Zou as saying.
He stressed that the moon’s hidden side was attractive to scientists due to the absence of electromagnetic waves, making it an ideal site for low-frequency radio research.
"If we can can place a frequency spectrograph on the far side, we can fill a void," Zou told the conference.
China’s ambitious space program also includes a permanent space station and manned flights to the moon and Mars.
