BEIJING, Nov. 25 (Xinhua) -- The following is a summary of published science and technology news of China.


Two space tracking ships from China's Yuanwang fleet completed their maritime monitoring of the Chang'e-5 probe launch in the Pacific Ocean on Tuesday morning.

The maritime monitoring process lasted a total of 1,100 seconds. The two ships sent accurate real-time data to spacecraft control centers in Beijing and Wenchang, laying the foundation for the Chang'e-5 mission.


China's lunar probe Chang'e-5 successfully carried out its first orbital correction Tuesday night.

The probe conducted the orbital correction at 10:06 p.m. (Beijing Time) when its 3000N engine was operational for about two seconds, and then continued its trip to the moon.

Prior to the orbital correction, the lunar probe had traveled for roughly 17 hours in space, and was about 160,000 km away from Earth. All of the probe's systems were in good condition.


A Chinese museum said it has found the world's smallest dragonflies in terms of body length in samples collected from southwest China.

The samples from Sichuan Province were identified as those of Nannophya pygmaea, commonly known as scarlet dwarf, with the smallest adult specimen having a body length of about 15 mm, according to the Insect Museum of West China. Enditem
