Aug. 23 (UPI) -- China's space agency on Sunday postponed the launch of an ambitious mission to search the south pole of the moon for ice due to poor weather.

The robotic lunar probe Chang'e-7 had been slated to take off on Sunday night but failed to meet launch conditions, the China Manned Space Agency said.

The agency added an "assessment was conducted following the principle of prudence, reliability and absolute mission success," Xinhua reported.

The main reason for the delay was poor weather due to Tropical Depression Narra in the Gulf of Tonkin, Space.com reported.
