China is planning on sending the first-ever lunar probe to the dark side of the moon by 2020, a leading engineer announced on state-run television. The goal of the mission would be to examine the geological conditions there with the ultimate aim of installing a radio telescope. 
 
 China's lunar exploration program -- known as Chang'e -- is leading the mission, Zou Yongliao of the Chinese Academy of Sciences' moon exploration department told CCTV in an interview shown Wednesday. A successful landing, which would be the first of its kind, could enable the Chinese to place radio transmitters on the far side of the moon, which currently can't be reached with transmissions from Earth. This new look at the universe woud “fill a void” in humanity's understanding of outer space, Zou said, as quoted by the Associated Press. 
 
 The dark side of the moon is not visible from Earth. While China became the third country (after the United States and the Soviet Union) to land a probe on lunar soil in 2013, reaching the dark side of the moon will require more satellite technology to communicate with the probe, simply because the moon itself is blocking radio transmissions. 
 
 “The communication problem will be solved by having a spacecraft orbiting the moon to relay radio signals from the far side of the moon back to earth,” Michael Brown, an observational astronomer at Monash University in Austrailia, told Al Jazeera. “This shouldn't be too difficult a problem to solve, given spacecraft orbiting Mars regularly relay signals from the Opportunity and Curiosity rovers that are driving around on that planet.” ||||| These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to.

 The Chang'e 4 mission is planned for sometime before 2020, Zou Yongliao from the Chinese Academy of Sciences' moon exploration department told state broadcaster CCTV in an interview broadcast on Wednesday. 
 
 Zou said the mission's objective would be to study geological conditions on the moon's far side, also known as the dark side. 
 
 That could eventually lead to the placement of a radio telescope for use by astronomers, something that would help "fill a void" in man's knowledge of the universe, Zou said. 
 
 Radio transmissions from Earth are unable to reach the moon's far side, making it an excellent location for sensitive instruments. 
 
 China's next lunar mission is scheduled for 2017, when it will attempt to land an unmanned spaceship on the moon before returning to Earth with samples. If successful, that would make China only the third country after the United States and Russia to have carried out such a maneuver. 
 
 China's lunar exploration program, named Chang'e after a mythical goddess, has already launched a pair of orbiting lunar probes, and in 2013 landed a craft on the moon with a rover onboard. 
 
 China has also hinted at a possible crewed mission to the moon. 
 
 China sent its first astronaut into space in 2003 and has powered ahead with a series of methodically timed steps, including the deploying of an experimental space station.
– If everything goes to plan with China's space program—which so far everything has since the country launched its first astronaut in 2003—it will become the first country to land a probe on the "dark side of the moon," the AP reports. This week, Zou Yongliao of the Chinese Academy of Sciences announced plans to send a probe designated Chang'e 4 to the moon's far side by 2020, according to the Asia Times. "China will be the first to complete the task if it is successful," Zou said. In 2013, China became the third country to land a probe—Chang'e 3—on the moon, following the United States and Soviet Union. China plans to study the geology of the far side of the moon—which is never visible from Earth—in order to put a radio telescope there. The dark side of the moon would be ideal for studying radio waves because the moon itself blocks any interfering waves coming from Earth. However, that also makes landing a probe on the moon's far side more difficult, according to the International Business Times. Without radio signals from Earth, China will require additional satellite technology to communicate with the probe. In the meantime, the AP reports that China will be sending an unmanned spaceship to and from the moon to collect samples in 2017. (NASA recently captured an amazing shot of the far side of the moon.)
