一、Two new satellites of BeiDou Navigation(导航) Satellite System (BDS) ①__________ (send) into space on a Long March-3B carrier rocket from the Xichang Satellite Launch Center in Sichuan Province, China at 2:07 a.m. on November 19, 2018. The satellites entered a Medium Earth orbit ②__________(safe) more than three hours later and will work with 17 other BDS-3 satellites already in space. They are also the 42nd and 43rd ③__________ (member) of the BDS satellite family.

China launched these satellites with ④__________aim of providing navigation services for countries and regions which participate in the Belt and Roa d Proposal by the end of 2018. “This is

a key step for BDS developing ⑤__________a Chinese experimental system to a regional and then a ⑥__________(globe) navigation system,” said Yang Changfeng, chief designer of the BeiDou system. The positioning ⑦__________(accurate) of the BDS-3 system has been improved to 2.5 meters to 5 meters, said Yang.

⑧__________(name) after the Chinese term for the Plough, the BeiDou system has been serving China for 18 years ⑨__________another six BDS-3 satellites will be put into the Medium Earth orbit from 2019 to 2020. The system is expected ⑩__________(provide)

first-class services around the globe by the end of 2020.

二、 Beijing—(13, July) China sent up a new data relay satellite(数据中继卫星), TianlianⅠ-02, on Monday at the Xichang Satellite Launch Centre in South-western Sichuan province. The new satellite will promote the country’s satellite communication network for space docking(对接).

The satellite was launched on a Long-March-3C carrier rocket at 11:41 p.m., sources at the centre told Xinhua News Agency. The satellite separated from the rocket 26 minutes after its launch and was then successfully delivered into a geostationary transfer orbit (地球同步转移轨道).

Developed by the China Academy of Space Technology under the China Aerospace Science and Technology Corporation, the satellite is the country’s second data relay satellite. The first, Tianlian Ⅰ-01, was launched on April 25.2008.

The two satellites will form a netwo rk to improve communications between China’s spacecraft and bases on Earth, according to the centre. They will also be used to help the nation’s first space docking, scheduled for the second half of this year.

As planned, China will launch space module Tiangong-Ⅰ, which was designed as a platform that will dock with an unmanned spaceship, Shenzhou, for the county’s first space-docking mission this year. Two more Shenzhou spaceships will dock with Tiangong-Ⅰ next year, and one will be manned by two or three astronauts, according to China Manned Space Engineering Office, which was the main user of the Tianlian Ⅰ series data relay satellites.

“The new satellite can cover a greater area to track and command the country’s space vehicles
