BEIJING, Jan. 18 (Xinhua) -- The following is a summary of published science and technology news of China.

ASTEROID NEAR-EARTH PASS

An asteroid half the size of a football field is set to make a near-Earth pass next month, posing no threat to the planet, the Purple Mountain Observatory of the Chinese Academy of Sciences said.

The asteroid was first spotted by the observatory on Jan. 1. The Minor Planet Center under the International Astronomical Union confirmed the asteroid discovery and designated it 2022 AA, meaning it is the first near-Earth asteroid to be discovered this year. Observation stations in the United States and Chile have since kept a close eye on it.

BIONIC SENSING ARRAY

Chinese researchers have developed a tactile-olfactory sensing array to facilitate search and rescue work in darkness or buried scenarios caused by geological disasters.

The design of the bionic sensing array, inspired by the natural sense-fusion system of star-nose mole, can enable real-time acquisition of the local topography, stiffness, and odor of a variety of objects in non-visual environments.

SATELLITES DELIVERY

The first batch of low-Earth orbit (LEO), broadband communication satellites developed by China's satellite producer GalaxySpace has rolled off the production line.

The six LEO broadband communication satellites, produced by the Beijing-based company within 11 months, have been transported to the launch center and are slated to be launched in the first quarter of 2022.

This is the first time that the country has completed the mass production of LEO broadband communication satellites.
