Orbiting the earth
Every now and then you may hear news of satellites (卫星) sent into space. On
Feb 21, for example, US company Space X took 46 satellites into orbit (轨道). On
Feb 27, China sent 22 satellites into space. Why do we need so many satellites? What
do they do for us?
At present, there are more than 3,000 active satellites moving around the Earth,
according to Statista, a German company that works on market data. Satellites have
all kinds of roles, from transmitting TV signals, giving you directions on the road, to
helping scientists with their re-search.
For example, the 22 satellites China just sent up are part of the BeiDou
Navigation Satellite System( 北斗卫星导航系统）.Shared bikes that use BeiDou
chips ( 芯 片 ) can provide more accurate positioning, making them easier to
find. Drones(① 无人机)can also use BeiDou while flying.
Before satellites, TV signals didn't reach very far. Mountains or tall buildings
would block the signals. Phone calls to faraway places were also a problem. Setting
up telephone wires over long distances is difficult. With satellites, TV signals and
phone calls can be sent directly to a satellite and back down to different locations on
Earth. SpaceX's Starlink project is trying to go further.It plans to use satellites to
provide people with internet all over the globe.
Satellites can also provide information about clouds, oceans, land and ice. They
help scientists predict changes in weather and climate. By monitoring wildfires and
volcanoes, satellites help emergency workers(应急人员）deal with natural disasters.
Farmers can use satellite images to decide the best time to water their fields.
Some satellites fly near other planets. They may look for water on Mars or take
close-up pictures of Saturn's rings( 土 星 环 ） .In 2020,video website Bilibili sent a
satellite into space. Its job is to look at other planets and share the pictures and videos
with Bilibili's users.
1. Why are satellites the US and China have sent to space mentioned at the
beginning of the text?
A. To point out which country has the most satellites.
