Chinese scientists said there's no water on the moon based on data collected by China's first lunar probe.

China Central Television (CCTV) quoted scientists in a report on Sunday as saying that images from a moon-based optical telescope on China's lunar probe Chang'e-3 confirms for the first time in history that no water exists in the Mare Imbrium Plain or Sea of Rains.

"We've measured the amount of water on the surface and found the lowest quantities so far, which meets our expectations," Wei Jianyan, a researcher from the National Astronomical Observatories of the Chinese Academy of Sciences.

Chang'e-3 has achieved other breakthroughs in scientific research since its successful landing on December 14, 2013, and its findings have been acknowledged by international counterparts, according to the State Administration of Science, Technology and Industry for National Defense (SASTIND).

Chang's-3 made the first cross-section map of the moon and discovered a brand-new type of rock - lunar basalt - which shows the geological structure and evolution 330 meters below the surface.

The optical telescope also enables Chinese scientists to complete their first celestial census on the ultraviolet wave band above the moon's North Pole.

"It provides the first sample for astronomers to do comparative studies," said Wei.

The ultraviolet camera on Chang'e-3 has also provided sufficient information for weather forecasting, guaranteed the smooth communication on Earth as well as between spacecrafts and the Earth by observing solar storms.

On Thursday, Chang'e-3 entered its 33rd dormant phase on the moon. No active lunar probe in history has served longer than Chang'e-3, according to SASTIND.

The first lunar rover Yutu, or Jade Rabbit, whose tasks included surveying the moon's geological features and surface substances and looking for natural resources, successfully completed its missions before it was retired.
